Background The performance of current diagnostic algorithms of the American College of Cardiology/American Heart Association (ACC/AHA), National Institute for Health and Care Excellence (NICE) and European Society of Cardiology (ESC) in patients with stable chest pain and coronary artery calcium (CAC) remains a matter of debate. We compared their merits in patients with CAC and investigated the additional value of the CAC score to improve diagnostic accuracy and risk stratification. Methods and results Patient data were obtained from a prospective registry of 642 consecutive patients. Mean age 63 (SD 11) years, 50% male. According to the guidelines, low and intermediate/high pre-test probability groups were constructed. Patients were reclassified based on their CAC score. Obstructive coronary artery disease (CAD) was observed in 14%. All models performed modestly in accurately predicting CAD (c-statistic <0.65). After addition of the CAC score, the c-statistic of the NICE model increased to 0.75 (95% confidence interval (CI) 0.73-0.78) which was just non-significant compared to the ESC model (0.71 95% CI 0.67-0.74) and performed significantly better than ACC/AHA (0.68 (95% CI 0.64-0.72)). After reclassification more than 50% of patients were classified low risk in NICE and ESC, while the prevalence of obstructive CAD (4.8% and 5.2% respectively) did not increase. Conclusions Addition of the CAC score to the studied models improved the ability to safely rule-out obstructive CAD and identified other patients at high risk for future coronary artery events. These results suggest that incorporating CAC score will lead to substantially less downstream testing and lower costs., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Objectives: The aim of this study was to evaluate the very long-term clinical outcome after radioactive stent (RS) implantation and intracoronary β radiation brachytherapy (IRBT)., Background: Radioactive stents (RS) and intracoronary β radiation brachytherapy (IRBT) were introduced to prevent restenosis after percutaneous coronary intervention (PCI). Both techniques were associated with a higher incidence of major adverse cardiac events (MACE) in the short and intermediate-term follow up as compared to conventional PCI., Methods: One hundred and thirty-three patients received radioactive stents ( 32 P) and 301 patients were treated with IRBT adjunctive to PCI. These groups were propensity matched to respectively 266 and 602 control patients who were treated with routine PCI during the same inclusion period. Endpoints were all-cause mortality and MACE, defined as all-cause death, any myocardial infarction or any revascularization., Results: Median follow-up duration was 17 years. All-cause mortality rates were similar in all groups. Adjusted hazard ratios for MACE and mortality in the RS cohort were 1.55 (95% CI 1.20-2.00) and 0.92 (95% CI 0.63-1.34), respectively. Adjusted hazard ratios for MACE and all-cause mortality in the IRBT cohort were 1.41 (95% CI 1.18-1.67) and 0.95 (95% CI 0.74-1.21), respectively. The difference in MACE rates was predominantly driven by coronary revascularizations in both groups, with a higher MI rate in the IRBT group as well., Conclusions: Coronary radiation therapy was associated with early increased MACE rates, but the difference in MACE rates decreased beyond 2 years, resulting in a comparable long-term clinical outcome. Importantly, no excess in mortality was observed., (© 2019 The Authors. Catheterization and Cardiovascular Interventions published by Wiley Periodicals, Inc.)

Objectives: This study assessed whether adenosine stress-only perfusion cardiac magnetic resonance (CMR) following a positive coronary artery calcium (CAC) score improved the diagnostic yield of invasive coronary angiography (CAG) in patients with stable chest pain. The study also established the association between positive CAC scores and stress-induced myocardial ischemia., Background: The diagnostic yield of catheterization among patients with suspected coronary artery disease (CAD) is low. Improved patient selection and diagnostic testing are necessary. The CAC score can minimize unnecessary diagnostic testing, and in low-risk patients, normal CMR results have a high negative predictive value. Less comprehensive protocols may be sufficient to guide further work-up., Methods: A total of 642 consecutive patients (mean age: 63 years; 50% women) with stable chest pain and CAC scores of >0 who were referred for CMR were enrolled. Patients with a perfusion defect were subsequently examined by CAG. Patients were followed up for 1 year. Outcome was obstructive CAD., Results: Obstructive CAD was present in 12% of patients. For CAD diagnosis, the sensitivity of adenosine CMR was 90.9% (95% confidence interval [CI]: 88.7 to 93.1), specificity was 98.7% (95% CI: 97.9 to 99.6), positive predictive value was 92.0% (95% CI: 89.8 to 94.1), and negative predictive value was 98.6% (95% CI: 97.6 to 99.5). A CAC score between 0.1 and 100 without typical angina was associated with obstructive CAD in only 3% of patients. Patients with nonanginal chest pain and a CAC score ≥400 had obstructive CAD (16%)., Conclusions: Stress-only adenosine CMR had high diagnostic accuracy and served as an efficient gatekeeper to CAG in stable patients with a CAC score >0. Patients with CAC scores between 0.1 and 100 could be deferred from further testing in the absence of clinical features that suggested high risk. However, in patients with CAC score ≥400, functional testing should be indicated, regardless of the type of chest pain., (Copyright © 2020 American College of Cardiology Foundation.

Objective: To examine the strength of the association between exercise capacity and health-related quality of life (HRQOL) during and after cardiac rehabilitation (CR) in patients with acute coronary syndrome (ACS) who completed CR., Design: Prospective cohort study., Setting: Outpatient CR center., Participants: Patients (N=607) with ACS who completed CR., Interventions: Multidisciplinary 12-week exercise-based CR program., Main Outcome Measures: At baseline (pre-CR), the 6-Minute Walk Test (6MWT) was performed to determine exercise capacity, and the MacNew Heart Disease Health-related Quality of Life questionnaire was used to assess HRQOL. Measurements were repeated immediately after completion of CR (post-CR): at 12 months and 18 months follow-up. Multivariable linear regression, including an interaction term for time and exercise capacity, was applied to study the association between exercise capacity and HRQOL at different time points relative to CR, whereas model parameters were estimated by methods that accounted for dependency of repeated observations within individuals., Results: Mean age in years ± SD was 58±8.9 and 82% of participants were male. Baseline mean 6MWT distance in meters ± SD was 563±77 and median (25th-75th percentile) global HRQOL was 5.5 (4.6-6.1) points. Mean 6MWT distance (P<.001) and the global (P<.001), physical (P<.001), emotional (P<.001) and social (P<.001) domains of HRQOL improved significantly during CR and continued to improve during follow-up post-CR. Independent of the timing relative to CR (ie, pre-CR, post-CR, or during follow-up), a difference of 10 m 6MWT distance was associated with a mean difference in the global HRQOL domain of 0.007 (95% confidence interval [CI], 0.001-0.014) points (P=.029) and a mean difference in the physical domain of 0.009 (95% CI, 0.001-0.017) points (P=.023)., Conclusions: Better exercise capacity was significantly associated with higher scores on the global and physical domains of HRQOL, irrespective of the timing relative to CR, albeit these associations were weak. Hence, CR programs in secondary prevention should continue to aim at enhancing both HRQOL and exercise capacity., (Copyright © 2020 American Congress of Rehabilitation Medicine.

Background: Coronary artery calcium (CAC) scanning has evolved into an important subclinical prediction method for cardiovascular diseases in asymptomatic subjects. However, the prognostic implication of CAC scanning in symptomatic individuals is less clear., Objectives: To assess the prognostic utility of CAC in predicting risk of major adverse cardiac events (MACE) in stable patients with suspected CAD., Methods: We did a systematic electronic literature search for studies presenting original data in CAC score, and reporting cardiovascular events in stable, symptomatic patients as primary outcome. Primary outcome of the meta-analysis was the occurrence of MACE, a composite of late coronary revascularization, hospitalization for unstable angina or heart failure, nonfatal myocardial infarction, and cardiac death or all-cause mortality. Using random effects models, we pooled relative risk ratios of CAC for MACE, and adjusted hazard ratios (HR) of the associations between different CAC strata (CAC 0-100,100-400, and ≥ 400, versus CAC = 0) and incident MACE., Results: We included 19 observational studies (n = 34,041). In total, 1601 events were analyzed, of which 158 in patients with CAC = 0. The pooled relative risk ratio was 5.71 (95%-CI: 3.98;8.19) for subjects with CAC > 0. The pooled estimate of adjusted HRs demonstrated increasing, positive associations, with the strongest association for CAC > 400 (HR: 4.88; 95%-CI: 2.44;9.27)., Conclusions: This meta-analysis demonstrated that increased levels of CAC are strongly and independently associated with increased risk for MACE in stable, symptomatic patients with suspected CAD, showing increasing risk with greater CAC scores. Application of CAC scanning as a prediction method could be useful for a considerable number of such patients., (Copyright © 2019. Published by Elsevier B.V.)

Objective: In this secondary analysis of data from the OPTICARE trial, we compared the effects of two behavioral interventions integrated into cardiac rehabilitation to standard rehabilitation with regard to functional capacity, fatigue, and participation in society., Design: This is a randomized controlled trial., Setting: This study was conducted in a cardiac rehabilitation setting., Subjects: A total of 740 patients with acute coronary syndrome were recruited for this study., Interventions: Patients were randomized to (1) three months of standard rehabilitation; (2) cardiac rehabilitation plus nine months after-care with face-to-face group lifestyle counseling; or (3) cardiac rehabilitation plus nine months after-care with individual lifestyle telephone counseling., Main Measures: Functional capacity (6-minute walk test), fatigue (Fatigue Severity Scale), and participation in society (Utrecht Scale for Evaluation of Rehabilitation-Participation) were measured at randomization, 3, 12, and 18 months., Results: Additional face-to-face sessions resulted at 12 months in 12.49 m more on the 6-minute walk test compared to standard rehabilitation ( P = .041). This difference was no longer present at 18 months. Prevalence of fatigue decreased from 30.2% at baseline to 11.9% at 18 months compared to an improvement from 37.3% to 24.9% after standard rehabilitation (between-group difference: odds ratio = 0.47; P = .010). The additional improvements in functional capacity seemed to be mediated by increases in daily physical activity. No mediating effects were found for fatigue. No additional improvements were seen for participation in society. Additional telephonic sessions did not result in additional intervention effects., Conclusion: Extending cardiac rehabilitation with a face-to-face behavioral intervention resulted in additional long-term improvements in fatigue and small improvements in functional capacity up to 12 months. A telephonic behavioral intervention provided no additional benefits.

Objectives: Our goal was to evaluate the outcomes of the first patients treated by venous coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCIs) with balloon angioplasty at a single centre who have reached up to 40 years of life-long follow-up., Methods: We analysed the outcomes of the first consecutive patients who underwent (venous) CABG (n = 1041) from 1971 to 1980 and PCI (n = 856) with balloon angioplasty between 1980 and 1985. Follow-up was successfully achieved in 98% of patients (median 39 years, range 36-46) who underwent CABG and in 97% (median 33 years, range 32-36) of patients who had PCI., Results: The median age was 53 years in the CABG cohort and 57 years in the PCI cohort. A total of 82% of patients in the CABG group and 37% of those in the PCI group had multivessel coronary artery disease. The cumulative survival rates at 10, 20, 30 and 40 years were 77%, 39%, 14% and 4% after CABG, respectively, and at 10, 20, 30 and 35 years after PCI were 78%, 47%, 21% and 12%, respectively. The estimated life expectancy after CABG was 18 and 17 years after the PCI procedures. Repeat revascularization was performed in 36% and 57% of the patients in the CABG and PCI cohorts, respectively., Conclusions: This unique life-long follow-up analysis demonstrates that both CABG and PCI were excellent treatment options immediately after their introduction as the standard of care. These procedures were lifesaving, thereby indirectly enabling patients to be treated with newly developed methods and medical therapies during the follow-up years., (© The Author(s) 2019.

Background: Myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) is useful in the evaluation of cardiac allograft vasculopathy (CAV) in heart transplant (HTx) recipients. The current study evaluated the long-term prognostic value of stress SPECT MPI for predicting all-cause mortality and cardiac events in HTx recipients., Methods: The study population consisted of 166 HTx recipients (mean age 54 ± 10 years, 84% male) who underwent exercise or dobutamine stress 99m Tc-tetrofosmin SPECT MPI for the assessment of CAV. An abnormal SPECT MPI was defined as the presence of a fixed or a reversible perfusion defect. Endpoints were all-cause mortality, cardiac mortality, and non-fatal myocardial infarction (MI)., Results: MPI abnormalities were detected in 55 patients (33%), including fixed defects in 28 patients (17%), partially reversible in 17 patients (10%), and completely reversible defects in 10 patients (6%). During a median follow-up of 12.8 years (range 0-15, mean follow-up 9.5 years), 109 (66%) patients died (all-cause mortality), of which 67 (40%) were due to cardiac causes. A total of 5 (3%) patients experienced a non-fatal MI. HTx recipients with a normal stress 99m Tc-tetrofosmin SPECT MPI had a significantly better prognosis as compared with those with an abnormal study, up to 5 years after the initial test. The presence of a reversible perfusion defect was a significant predictor of all-cause mortality, cardiac mortality, and major cardiac events, during the entire follow-up period., Conclusions: Stress 99m Tc-tetrofosmin SPECT MPI provides valuable prognostic information for the prediction of long-term outcome in HTx recipients. Patients with a normal stress 99m Tc-tetrofosmin SPECT MPI have a significantly better prognosis as compared with those with an abnormal study, up to 5 years after initial testing.

Objectives: The Heart Team has been recommended as standard care for patients with coronary artery disease (CAD). However, little is known about the real benefits, potential treatment delays and late outcomes of this approach. Our goal was to determine the safety and feasibility of multidisciplinary Heart Team decision making for patients with CAD., Methods: We retrospectively assessed 1000 consecutive cases discussed by the Heart Team between November 2010 and January 2012. We assessed (i) time intervals between different care steps involving the Heart Team; (ii) the distribution of patients according to the complexity of their CAD; and (iii) the 5-year survival as estimated from Kaplan-Meier curves., Results: Of 1000 case discussions, 40 were repeat cases, resulting in 960 unique cases. The mean age was 65 years, 73% were men, and 29% had diabetes. Native vessel disease was present in 86.4%, of which 69% had simple 1-vessel disease (1VD) or 2-vessel disease (2VD), and 31% had complex left main (LM) or 3-vessel disease (3VD). The time interval between referral by a community hospital and final treatment was less than 6 weeks for 90% of cases. Treatment decisions were delayed in 35% of cases due to a need for additional diagnostic information. For simple 1- or 2VD with or without proximal left anterior descending artery involvement, treatment was medical therapy in 6% and 12%, respectively; percutaneous coronary intervention (PCI) in 88% and 85%, respectively; and coronary artery bypass grafting (CABG) in 6% and 3%, respectively. For 3VD disease, treatment was equally split between CABG and PCI (46% for both). PCI was preferred for isolated LM or LM with 1VD (81% vs CABG 16%), whereas CABG was preferred in LM with 2- or 3VD (71% vs PCI 19%). The 5-year mortality rate was 16% for 1- or 2VD, 17% for 3VD, 3% for isolated LM or with 1VD and 27% for LM with 2- or 3VD., Conclusions: In this single-centre analysis, the Heart Team approach was feasible, with decision making and treatment by the Heart Team following within a short time after referral. However, the timing of treatment could be further optimized if adequate information and imaging were available at the time of the Heart Team meeting. The final treatment recommendation by the Heart Team was largely in accordance with clinical guidelines.

Background: Renal dysfunction and anaemia are common in patients with acute heart failure (HF). It is not known whether their combined presence has additive prognostic value. We investigated their prognostic value separately and in combination, on prognosis in acute HF patients. Furthermore, we examined whether the improvement in prognosis was comparable between patients with and without renal dysfunction., Methods and Results: This prospective registry includes 1783 patients admitted to the (Intensive) Coronary Care Unit for acute HF in the period of 1985-2008. The outcome measure was the composite of all-cause mortality, heart transplantation and left ventricular assist device implantation. In patients without renal dysfunction, anemia was associated with worse 30-day outcome (HR 2.91; [95% CI 1.69-5.00]), but not with 10-year outcome (HR 1.13 [95% CI 0.93-1.37]). On the contrary, anemia was found to influence prognosis in patients with renal dysfunction, both at 30 days (HR 1.93 [95% CI 1.33-2.80]) and at 10 years (HR 1.27 [95% CI 1.10-1.47]). Over time, the 10-year survival rate improved in patients with preserved renal function (HR 0.73 [95% CI 0.55-0.97]), but not in patients with renal dysfunction., Conclusion: The long-term prognosis of acute HF patients with a preserved renal function was found to have improved significantly. However, the prognosis of patients with renal dysfunction did not change. Anemia was a strong prognosticator for short-term outcome in all patients. In patients with renal dysfunction, anemia was also associated with impaired long-term prognosis., Competing Interests: The authors have declared that no competing interests exist.

Aims: We aimed to assess the effects of a multidisciplinary cardiac rehabilitation (CR) program on survival after treatment with primary percutaneous coronary intervention (pPCI) for acute coronary syndrome (ACS)., Methods and Results: Using propensity matching analysis, a total of 1159 patients undergoing CR were 1:1 matched with ACS patients who did not undergo CR and survived at least 60 days. The Kaplan-Meier analyses and multivariate Cox regression analysis were applied to study differences in survival. During follow-up, a total of 335 (14.5%) patients had died. Cumulative mortality rates at 5 and 10 years were 6.4% and 14.7% after CR and 10.4% and 23.5% in the no CR group (P < 0.001). Cardiac rehabilitation patients had 39% lower mortality than non-CR controls [10-year mortality 14.7% vs. 23.5%; adjusted hazard ratio (HR) 0.61; 95% confidence interval (CI) 0.46-0.81]. A total of 915 (78.9%) patients completed CR and had 46% lower mortality than those who did not complete CR (10-year mortality 13.6% vs. 18.9%; adjusted HR 0.54; 95% CI 0.42-0.70)., Conclusion: Patients who underwent pPCI for ACS, with a CR program had lower mortality than their non-CR counterparts. Mortality was particularly low in patients who completed the program. In conclusion, CR is still beneficial in terms of survival.

Background: It is not entirely clear whether ischemia burden on stress single-photon emission computed tomography (SPECT) effectively identifies patients who have a long-term benefit from coronary revascularization., Methods: The study population consisted of 719 patients with ischemia on stress SPECT. Early coronary revascularization was defined as percutaneous coronary intervention or coronary artery bypass grafting ≤90 days after SPECT. Patients who underwent late revascularization (>90 days after SPECT) were excluded (n = 164)., Results: Of the 538 patients (73% men, mean age 59.8 ± 11 years), 348 patients had low ischemia burden (<3 ischemic segments) and 190 patients had moderate to high ischemia burden (≥3 ischemic segments). A total of 76 patients underwent early revascularization. During a median follow-up of 12 years (range 4-17), 283 patients died of whom 125 due to cardiac causes. Early revascularization was beneficial on all-cause mortality (HR 0.46, 95% CI 0.30-0.46) and cardiac mortality (HR 0.54, 95% CI 0.29-0.99)., Conclusions: Patients with myocardial ischemia on stress SPECT who underwent early revascularization had a lower all-cause mortality and cardiac mortality during long-term follow-up as compared to patients who received pharmacological therapy alone. This difference in long-term outcomes was mainly influenced by the survival benefit of early revascularization in the patients with moderate to high ischemia burden.

Aims: Currently, comparative data on procedural and long-term clinical outcome of outflow tract (OT) idiopathic ventricular arrhythmia (IVA) ablation with manual (MAN), contact force (CF), and magnetic navigation system (MNS) ablation are lacking. The aim of this study was to compare the procedural and long-term clinical outcome of MAN, CF, and MNS ablation of OT IVAs., Methods and Results: Seventy-three patients (31 MAN, 17 CF, and 25 MNS patients; consecutive per group) with OT IVA, who underwent catheter ablation in our centre were analysed. Procedural success rates (success at the end of the procedure), procedural data and long-term follow-up data were compared. Baseline patient demographics were comparable. Procedural success rates were similar (MAN 81%, 71% CF, and MNS 92%; P = 0.20). Median fluoroscopy time was shorter in the MNS group: MAN 29 (16-38), CF 37 (21-46), and MNS 13 (10-20) min (P = 0.002 for MNS vs. CF and MAN). The overall complication rate was: MAN 10%, CF 0%, and MNS 0% (P = 0.12). Median follow-up was: MAN 2184 (1672-2802), CF 1721 (1404-1913), and MNS 3031 (2524-3286) days (P <0.001). Recurrences occurred in MAN 46%, CF 50%, and MNS 46% (P = 0.97). Repeat procedures were performed in MAN 20%, CF 40%, and MNS 33% (P = 0.32)., Conclusion: Procedural and long-term clinical outcome of OT IVA ablation are equal for MAN, CF, and MNS. MNS has a favourable procedural safety profile due to the shorter fluoroscopy time compared with MAN and CF.

Left ventricular (LV) diastolic dysfunction is one of the important mechanisms responsible for symptoms in patients with heart failure. The aim of the current study was to identify parameters that may be used to detect early signs of LV diastolic dysfunction in diabetic pigs on a high fat diet, using conventional and speckle tracking echocardiography. The study population consisted of 16 healthy Göttingen minipigs and 18 minipigs with experimentally induced metabolic dysfunction. Echocardiography measurements were performed at baseline and 3-month follow-up. The ratio of peak early (E) and late filling velocity (E/A ratio) and the ratio of E and the velocity of the mitral annulus early diastolic wave (E/Em ratio) did not change significantly in both groups. Peak untwisting velocity decreased in the metabolic dysfunction group (- 30.1 ± 18.5 vs. - 23.4 ± 15.5 °/ms) but not in controls (- 38.1 ± 23.6 vs. - 42.2 ± 23.0 °/ms), being significantly different between the groups at the 3-month time point (p < 0.05). In conclusion, whereas E/A ratio and E/Em ratio did not change significantly after 3 months of metabolic dysfunction, peak untwisting velocity was significantly decreased. Hence, peak untwisting velocity may serve as an important marker to detect early changes of LV diastolic dysfunction.

Background: Both dobutamine stress echocardiography (DSE) and myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) are frequently used for cardiac risk stratification. The long-term relative prognostic value of these modalities has not been studied. Therefore, this study evaluated the long-term prognostic value of DSE compared to MPI in patients unable to perform exercise testing., Methods: This prospective, single center study included 301 patients (mean age 59 ± 12 years, 56% men) unable to perform exercise tests who underwent DSE and dobutamine stress 99m Tc-sestamibi MPI. End points during follow-up were all-cause mortality, cardiac mortality, and nonfatal myocardial infarction (MI). Univariable and multivariable Cox proportional hazards regression models were used to identify independent predictors of outcome. The probability of survival was calculated using the Kaplan-Meier method., Results: A total of 182 patients (60%) had an abnormal DSE and 198 (66%) patients had an abnormal MPI. The agreement between DSE and MPI was 82% (κ = 0.62). During a median follow-up of 14 years (range 5-18), 172 deaths (57%) occurred, of which 72 (24%) were due to cardiac causes. Nonfatal MI occurred in 46 patients (15%). The multivariable analysis demonstrated that an abnormal DSE was a significant predictor of cardiac mortality (HR 2.35, 95% CI [1.17-4.73]) and hard cardiac events (HR 2.11, 95% CI [1.25-3.57]). Also, an abnormal MPI result was a significant predictor of cardiac mortality (HR 3.03, 95% CI [1.33-6.95]) and hard cardiac events (HR 2.06, 95% CI [1.12-3.79])., Conclusions: DSE and MPI are comparable in predicting long-term cardiac mortality and hard cardiac events in patients unable to perform exercise testing.

Background: Standard cardiac rehabilitation (CR) is insufficient to help patients achieve an active lifestyle. The effects of two advanced and extended behavioral CR interventions on physical activity (PA) and sedentary behavior (SB) were assessed., Methods: In total, 731 patients with ACS were randomized to 1) 3months of standard CR (CR-only); 2) 3months of standard CR with three pedometer-based, face-to-face PA group counseling sessions followed by 9months of aftercare with three general lifestyle, face-to-face group counseling sessions (CR+F); or 3) 3months of standard CR, followed by 9months of aftercare with five to six general lifestyle, telephonic counseling sessions (CR+T). An accelerometer recorded PA and SB at randomization, 3months, 12months, and 18months., Results: The CR+F group did not improve their moderate-to-vigorous intensity PA (MVPA) or SB time compared to CR-only (between-group difference=0.24% MVPA, P=0.349; and 0.39% SB, P=0.529). However, step count (between-group difference=513 steps/day, P=0.021) and time in prolonged MVPA (OR=2.14, P=0.054) improved at 3months as compared to CR-only. The improvement in prolonged MVPA was maintained at 18months (OR=1.91, P=0.033). The CR+T group did not improve PA or SB compared to CR-only., Conclusions: Adding three pedometer-based, face-to-face group PA counseling sessions to standard CR increased daily step count and time in prolonged MVPA. The latter persisted at 18months. A telephonic after-care program did not improve PA or SB. Although after-care should be optimized to improve long-term adherence, face-to-face group counseling with objective PA feedback should be added to standard CR., (Copyright © 2017 Elsevier B.V.

Objective: The OPTICARE (OPTImal CArdiac REhabilitation) randomised controlled trial compared two advanced and extended cardiac rehabilitation (CR) programmes to standard CR for patients with acute coronary syndrome (ACS). These programmes were designed to stimulate permanent adoption of a heart-healthy lifestyle. The primary outcome was the SCORE (Systematic COronary Risk Evaluation) 10-year cardiovascular mortality risk function at 18 months follow-up., Methods: In total, 914 patients with ACS (age, 57 years; 81% men) were randomised to: (1) 3 months standard CR (CR-only); (2) standard CR including three additional face-to-face active lifestyle counselling sessions and extended with three group fitness training and general lifestyle counselling sessions in the first 9 months after standard CR (CR+F); or (3) standard CR extended for 9 months with five to six telephone general lifestyle counselling sessions (CR+T)., Results: In an intention-to-treat analysis, we found no difference in the SCORE risk function at 18 months between CR+F and CR-only (3.30% vs 3.47%; p=0.48), or CR+T and CR-only (3.02% vs 3.47%; p=0.39). In a per-protocol analysis, two of three modifiable SCORE parameters favoured CR+F over CR-only: current smoking (13.4% vs 21.3%; p<0.001) and total cholesterol (3.9 vs 4.3 mmol/L; p<0.001). The smoking rate was also lower in CR+T compared with the CR-only (12.9% vs 21.3%; p<0.05)., Conclusions: Extending CR with extra behavioural counselling (group sessions or individual telephone sessions) does not confer additional benefits with respect to SCORE parameters. Patients largely reach target levels for modifiable risk factors with few hospital readmissions already following standard CR., Trial Registration Number: ClinicalTrials.gov NCT01395095; results., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Objectives: We aimed to develop a model to predict long-term mortality after percutaneous coronary intervention (PCI), to aid in selecting patients with sufficient life expectancy to benefit from bioabsorbable scaffolds., Background: Clinical trials are currently designed to demonstrate superiority of bioabsorbable scaffolds over metal devices up to 5 years after implantation., Methods: From 2000 to 2011, 19.532 consecutive patients underwent PCI in a tertiary referral hospital. Patients were randomly (2:1) divided into a training (N = 13,090) and validation (N = 6,442) set. Cox regression was used to identify determinants of long-term mortality in the training set and used to develop a risk model. Model performance was studied in the training and validation dataset., Results: Median age was 63 years (IQR 54-72) and 72% were men. Median follow-up was 3.6 years (interquartile range [IQR] 2.4-6.8). The ratio elective vs. non-elective PCIs was 42/58. During 88,620 patient-years of follow-up, 3,156 deaths occurred, implying an incidence rate of 35.6 per 1,000. Estimated 5-year mortality was 12.9%.Regression analysis revealed age, body mass index, diabetes mellitus, renal insufficiency, prior myocardial infarction, PCI indication, lesion location, number of diseased vessels and cardiogenic shock at presentation as determinants of mortality. The long-term risk model showed good discrimination in the training and validation sets (c-indices 0.76 and 0.74), whereas calibration was appropriate., Conclusions: A simple risk model, containing 9 baseline clinical and angiographic variables effectively predicts long-term mortality after PCI and may possibly be used to select suitable patients for bioabsorbable scaffolds., (© 2017 Wiley Periodicals, Inc.)

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia in the emergency department. The CHA 2 DS 2 -VASc score helps to predict thromboembolic risk; however, the rate of other adverse cardiac events is more difficult to predict., Hypothesis: The biomarker N-terminal pro-brain natriuretic peptide (NT-proBNP) has prognostic value in patients presenting to the emergency department with AF., Methods: During a 1.5-year period, a prospective study was performed in consecutive patients presenting to the emergency department with AF on the presenting electrocardiogram. At baseline, NT-proBNP was measured. The primary endpoints were all-cause death and major adverse cardiac events (MACE: all-cause mortality, myocardial infarction, or revascularization)., Results: A total of 355 patients were included (mean age, 71 years; 55% male). The median duration of follow-up was 2 years. After adjustment for baseline variables, the logNT-proBNP was independently correlated with death (hazard ratio [HR]: 1.54, 95% confidence interval [CI]: 1.18-1.99) and MACE (HR: 1.27, 95% CI: 1.03-1.58). After adjustment for baseline variables, a high NT-proBNP value (>500 pmol/L) was independently correlated with death (HR: 2.26, 95% CI: 1.19-4.28), and for MACE a trend was seen (HR: 1.67, 95% CI: 0.96-2.91) compared with a low value (<250 pmol/L)., Conclusions: In patients presenting to the emergency department with AF, higher NT-proBNP values are independently associated with an increased mortality and MACE. Therefore, this biomarker may be a useful prognostic marker in the management and treatment of these patients., (© 2018 Wiley Periodicals, Inc.)

Background: Hypertrophic cardiomyopathy (HC) is characterized by left ventricular (LV) hypertrophy and associated with papillary muscle (PM) abnormalities. The aim of this study was to evaluate the utility of three-dimensional echocardiography (3DE) for the geometric assessment of LV hypertrophy and PM morphology., Methods: The study included 24 patients with an established diagnosis of HC and 31 healthy controls. 3DE was performed using an iE33 or EPIQ 7C ultrasound system with an X5-1 transducer. QLAB software was used for the 3D analysis of LV wall thickness (LVWT) and PM morphology and hypertrophy; the number and cross-sectional area (CSA) of anterolateral and posteromedial PMs; and the presence of bifid or accessory PMs., Results: Patients with HC had a larger LVWT compared to controls in all segments (p < 0.001), and LVWT was largest in the midventricular septal segment (2.12 ± 0.68 cm). The maximum LVWT followed a spiral pattern from the LV base to the apex. The CSA of both anterolateral and posteromedial PMs was larger in patients with HC than in controls (1.92 vs. 1.15 cm 2 ; p = 0.001 and 1.46 vs. 1.08 cm 2 ; p = 0.033, respectively). The CSA of the posteromedial PM was larger in patients with LVOT obstruction than in those without (2.64 vs 1.16 cm 2 , p = 0.021)., Conclusions: 3DE allows the assessment of LV geometry and PM abnormalities in patients with HC. 3DE demonstrated that the maximum hypertrophy was variable and generally located in a spiral from the LV base to the apex.

Purpose: The association between body mass index (BMI) and subjective health status before and after cardiac rehabilitation (CR) and 1 year later was compared in patients undergoing primary percutaneous coronary intervention (pPCI) who did (CR group) and did not receive CR (no-CR group). The aim was to investigate the association between BMI and subjective health status based on the Short Form-12 questionnaire., Methods: Between 2009 and 2011, 242 patients with pPCI with an acute myocardial infarction completed a CR program and were compared with 115 patients in the no-CR group. All patients completed the Short Form-12 questionnaire at baseline, at 12 weeks, and at 1-year followup. The CR program consisted of a 2 sessions per week for 1.5 hours each for 12 weeks. Patients were categorized into 3 groups based on BMI: normal weight, overweight, and obese., Results: Compared with patients in the no-CR group, CR group patients in the overweight group significantly improved their subjective health status after CR and these improvements were sustained at 1-year followup. CR patients in the normal weight and obese groups did not significantly improve subjective health status. The overweight patients had the highest improvement in subjective health status (OR = 3.4 post-CR and 5.1 at 1 year of followup)., Conclusions: After CR, overweight patients showed the best improvement in subjective health status. CR did not significantly improve subjective health status in normal-weight and obese patients.

Objectives: To compare the occurrence of acute stent recoil in two different stent types (platinum chromium and cobalt chromium) and identify the potential predictors of significant acute stent recoil., Background: Acute stent recoil is frequently observed after percutaneous coronary intervention and has been associated with in-stent restenosis and in-stent thrombosis. Different stent designs may result in varying degrees of stent recoil., Methods: From a registry of "all-comers" treated with either the Xience Prime Cobalt Chromium or Promus Premier Platinum Chromium stent, a random sample of 100 patients was drawn. Acute stent recoil was defined as the minimal luminal diameter (MLD) of the last inflated balloon minus the MLD after, divided by the MLD of the last inflated balloon. Significant acute stent recoil was defined as recoil ≥10%., Results: A total of 123 lesions (61 Xience Prime vs 62 Promus Premier) in 100 patients were analyzed. Acute stent recoil of 8.6 ± 4.9% was observed in the Xience Prime group versus 8.7 ± 4.2% in the Promus Premier group, P = 0.970. In a multivariate model for significant acute stent recoil, a stent/vessel ratio ≥1 (hazard ratio 4.64 [1.94-11.12], P = 0.001), a balloon/stent ratio >1 (hazard ratio 3.83 [1.12-13.14], P = 0.032) and direct stenting (hazard ratio 0.42 [0.18-0.96], P = 0.039) were identified as predictors., Conclusions: No significant differences were observed in the extent of acute stent recoil between the Xience Prime and the Promus Premier stent. A larger stent/vessel ratio, a larger balloon/stent ratio, and direct stenting were associated with significant acute stent recoil ≥10%. © 2017 Wiley Periodicals, Inc., (© 2017 Wiley Periodicals, Inc.)

Background: Dobutamine stress myocardial perfusion imaging (MPI) is a useful alternative for the evaluation of coronary artery disease (CAD) in elderly patients who are unable to perform an exercise stress test. However, data on the long-term prognostic value of stress MPI in elderly patients are lacking. Therefore, this study evaluated the long-term prognostic value of dobutamine stress MPI in elderly patients unable to perform an exercise test., Methods: The study population consisted of 247 elderly patients (mean age 71 ± 5 years) who underwent dobutamine stress single-photon emission computed tomography (SPECT) MPI. An abnormal SPECT study was defined as the presence of fixed and/or reversible perfusion defects. A summed stress score (SSS) was obtained to estimate the extent and severity of perfusion defects. End points during follow-up were all-cause mortality, cardiac mortality, and nonfatal myocardial infarction (MI)., Results: During a median follow-up of 14 years (range 12-16), 168 (68%) patients died (all-cause mortality), of which 56 (23%) were due to cardiac causes. Nonfatal MI occurred in 19 (8%) patients. Kaplan-Meier survival curves showed that MPI provided optimal risk stratification in patients with normal and abnormal MPI. Multivariable analysis identified an abnormal MPI as a strong significant predictor of all-cause mortality and cardiac events. A multivariable analysis also revealed that a reversible defect and SSS were strong long-term predictors of cardiac mortality and hard cardiac events., Conclusion: Dobutamine stress 99m Tc-tetrofosmin SPECT provides incremental prognostic information for the prediction of long-term cardiovascular outcomes in elderly patients, unable to perform exercise testing. Dobutamine stress MPI is useful in risk classifying elderly patients.

Objective: We studied differences in long-term (i.e., 10 year) prognosis among patients with acute heart failure (HF) with and without diabetes over the last three decades. In addition, we investigated whether the degree of prognostic improvement in that period was comparable between patients with and without diabetes., Research Design and Methods: This prospective registry included all consecutive patients aged 18 years and older admitted to the Intensive Coronary Care Unit with acute HF in the period of 1985-2008. A total of 1,810 patients were included; 384 patients (21%) had diabetes. The outcome measure was the composite of all-cause mortality, heart transplantation, and left ventricular assist device implantation after 10-year follow-up., Results: The 10-year outcome in patients with diabetes was significantly worse than in those without diabetes (87% vs. 76%; adjusted hazard ratio [HR] 1.17 [95% CI 1.02-1.33]). Patients admitted in the last decade had a significantly lower 10-year event rate than patients admitted in the first two decades, both among patients without diabetes (adjusted HR 0.86 [95% CI 0.75-0.99]) and patients with diabetes (adjusted HR 0.80 [95% CI 0.63-1.00])., Conclusions: The long-term outcome of patients with diabetes is worse than that of patients without diabetes. However, the long-term prognosis improved over time in both groups. Importantly, this improvement in long-term prognosis was comparable in patients with and without diabetes. Despite these promising results, more awareness for diabetes in patients with acute HF is necessary and there is still need for optimal treatment of diabetes in acute HF., (© 2017 by the American Diabetes Association.)

Background: Since the early 2000s the treatment of choice for an acute myocardial infarction has moved from thrombolytic therapy to primary PCI (pPCI). As a result, the majority of patients undergoing PCI shifted from stable angina pectoris (SA) to acute coronary syndrome (ACS). Additionally the previously observed association between depression and anxiety and long-term outcome in patients who underwent a PCI may have been changed. The main objective of this study was to investigate the predictive value of depression and anxiety for 10-year mortality, in a cohort with post-PCI patients treated for SA versus patients treated for ACS., Methods: This prospective single center cohort consists of a consecutive series of patients (n=528) treated with PCI. At 1month post-PCI, patients completed the Dutch version of the Hospital Anxiety and Depression Scale (HADS)., Results: After adjustment for baseline characteristics depression was associated with higher 10-year mortality post-PCI (HR 1.58 95% Confidence Interval [95% CI] 1.04-2.40). In the ACS population no association between depression and 10-year mortality was found (HR 1.05 95% CI 0.62-1.79), in contrast to the SA population (HR 1.97 95% CI 1.09-3.57). After additional adjustment for anxiety, depression was no longer associated with higher mortality., Conclusions: Anxiety at baseline was associated with an increased 10-year mortality rate after PCI. Depression was also associated with higher 10-year mortality, however the association disappeared after additional adjustment for anxiety. This finding was more pronounced in patients presenting with SA as compared to those presenting with ACS, which might be a result of the increasing number of ACS patients treated with pPCI., (Copyright © 2017 Elsevier Ireland Ltd.

Purpose: Coupling interval (CI) variability of premature ventricular contractions (PVCs) is influenced by the underlying arrhythmia mechanism. The aim of this study was to compare CI variability of PVCs in different myocardial disease entities, in order to gain insight into their arrhythmia mechanism., Methods: Sixty-four patients with four underlying pathologies were included: idiopathic (n = 16), non-ischemic dilated cardiomyopathy (NIDCM) (n = 16), familial cardiomyopathy (PLN/LMNA) (n = 16), and post-MI (n = 16)-associated PVCs. The post-MI group was included as a reference, on account of its known re-entry mechanism. On Holter registrations, the first 20 CIs of the dominant PVC morphology were measured manually after which median ΔCI and mean SD of CI/√R-R (= CI of PVC corrected for underlying heart rate) were obtained. Two observers independently measured PVC CIs on pre-selected Holter registrations in order to determine inter- and intra-observer reliability., Results: The largest ΔCI was seen in the PLN/LMNA group (220 ms (120-295)), the lowest in the idiopathic group (120 ms (100-190)). The ΔCI in the PLN/LMNA group was significantly larger than the post-MI group (220 ms (120-295) vs 130 ms (105-155), p = 0.023). Mean SD of CI/√R-R in the PLN/LMNA group was also significantly higher than in the post-MI group (p = 0.044). Inter- and intra-observer reliability was good (ICC = 0.91 vs 0.86 and 0.96 vs 0.77, respectively)., Conclusions: Low ΔCI and SD of CI/√R-R of idiopathic and NIDCM PVCs suggest that the underlying arrhythmia mechanisms might be re-entry or triggered activity. Abnormal automaticity or modulated parasystole are unlikely mechanisms. High CI variability in PLN/LMNA patients suggests that the re-entry and triggered activity are less likely mechanisms in this group.

Background: It remains unclear whether feelings of being disabled are a relevant psychological factor that determines long term outcome after percutaneous coronary intervention (PCI). Therefore, we evaluated 'feelings of being disabled' as an independent risk factor for mortality 12years post-PCI., Methods: The study population comprised a consecutive series of CAD patients (n=845) treated with PCI as part of the Taxus-Stent Evaluated At Rotterdam Cardiology Hospital (T-SEARCH) registry. Of these patients n=646 (age 63years, 75% male) completed the subscale 'feelings of being disabled' of the Heart Patients Psychological Questionnaire (HPPQ), within the first month after PCI., Results: At 12year follow-up, n=209 patients (32%) died. Of the 162 females n=73 (45%) experienced high feelings of being disabled (High-FOBD) and of the 484 males, n=134 (28%) reported high-FOBD. Patients with high feelings of being disabled had a two-fold increased risk of mortality at 12-year follow-up (HR=1.86, 95% CI=1.41-2.45). After adjusting, high feelings of being disabled remained a predictor of 12-year mortality (HR=2.53, 95% CI=1.30-4.90)., Conclusions: This study confirms that psychosocial variables like feelings of being disabled influence cardiac morbidity and mortality. Furthermore, there is no difference in mortality between men and women with high feelings of being disabled 12years post-PCI. It is important that clinicians are aware that PCI-patients who feel disabled have a less favorable survival and that the difference in survival is even greater for women who feel disabled., (Copyright © 2017 Elsevier Ireland Ltd.

Objective: To objectively measure changes in both moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) during and after standard cardiac rehabilitation (CR)., Design: Prospective cohort study., Setting: Outpatient CR center., Participants: Patients (N=135) with acute coronary syndrome (ACS) who completed CR., Interventions: Multidisciplinary CR according to current guidelines., Main Outcome Measures: The proportion of time spent in MVPA and SB was objectively measured with an accelerometer. The distribution of time in MVPA and SB was also determined (eg, average length of time periods spent in MVPA and SB). All measurements were obtained before CR, after CR, and at 1-year follow-up., Results: Patients' time in MVPA during waking hours increased by .65% (≈5min) during CR (P=.002) and remained increased at 1-year follow-up (P=.037). The MVPA distribution did not change. During CR, time spent in SB decreased by 2.49% (≈22min; P<.001), and SB time became more fragmented with more breaks and shorter SB periods (P<.001). These SB improvements were maintained at 1-year follow-up (P<.001)., Conclusions: Patients with ACS achieved a small improvement in MVPA time during CR, but MVPA distribution remained unchanged. More substantial improvements occurred for SB time and distribution. However, by the end of CR, patients still spent relatively little time in MVPA and a long time in SB, which is known to be detrimental to cardiovascular health. Although CR programs have the potential to improve physical behavior, our findings highlight the need to develop adjusted CR targets that address the amount and distribution of MVPA and SB., (Copyright © 2017 American Congress of Rehabilitation Medicine.

Background: Speckle tracking echocardiography (STE) is an echocardiography modality that is able to measure left ventricular (LV) characteristics, including rotation, strain and strain rate. Strain measures myocardial fibre contraction and relaxation. This study aims to assess the effect of renal sympathetic denervation (RDN) on functional myocardial parameters, including STE, and to identify potential differences between responders and non-responders., Methods: The study population consisted of 31 consecutive patients undergoing RDN in the context of treatment for resistant hypertension. Patients were included between December 2012 and June 2014. Transthoracic echocardiography and speckle tracking analysis was performed at baseline and at 6 months follow-up., Results: The study population consisted of 31 patients with treatment-resistant hypertension treated with RDN (mean age 64 ± 10 years, 15 men). The total study population could be divided into responders (n = 19) and non-responders (n = 12) following RDN. RDN reduced office blood pressure by 18.9 ± 26.8/8.5 ± 13.5 mmHg (p < 0.001). A significant decrease was seen in LV posterior wall thickness (LVPWd) (0.47 ± 1.0 mm; p = 0.020), without a significant change in the LV mass index (LVMI). In the total cohort, only peak late diastolic filling velocity (A-wave velocity) decreased significantly by 5.3 ± 13.2 cm/s (p = 0.044) and peak untwisting velocity decreased significantly by 14.5 ± 28.9°/s (p = 0.025)., Conclusion: RDN reduced blood pressure and significantly improved functional myocardial parameters such as A-wave velocity and peak untwisting velocity in patients with treatment-resistant hypertension, suggesting a potential beneficial effect of RDN on myocardial mechanics.

Objective: Follow-up of right ventricular performance is important for patients with congenital heart disease. Cardiac magnetic resonance imaging is optimal for this purpose. However, observer-dependency of manual analysis of right ventricular volumes limit its use. Knowledge-based reconstruction is a new semiautomatic analysis tool that uses a database including knowledge of right ventricular shape in various congenital heart diseases. We evaluated whether knowledge-based reconstruction is a good alternative for conventional analysis., Design: To assess the inter- and intra-observer variability and agreement of knowledge-based versus conventional analysis of magnetic resonance right ventricular volumes, analysis was done by two observers in a mixed group of 22 patients with congenital heart disease affecting right ventricular loading conditions (dextro-transposition of the great arteries and right ventricle to pulmonary artery conduit) and a group of 17 healthy children. We used Bland-Altman analysis and coefficient of variation., Results: Comparison between the conventional method and the knowledge-based method showed a systematically higher volume for the latter group. We found an overestimation for end-diastolic volume (bias -40 ± 24 mL, r = .956), end-systolic volume (bias -34 ± 24 mL, r = .943), stroke volume (bias -6 ± 17 mL, r = .735) and an underestimation of ejection fraction (bias 7 ± 7%, r = .671) by knowledge-based reconstruction. The intra-observer variability of knowledge-based reconstruction varied with a coefficient of variation of 9% for end-diastolic volume and 22% for stroke volume. The same trend was noted for inter-observer variability., Conclusion: A systematic difference (overestimation) was noted for right ventricular size as assessed with knowledge-based reconstruction compared with conventional methods for analysis. Observer variability for the new method was comparable to what has been reported for the right ventricle in children and congenital heart disease with conventional analysis., (© 2017 Wiley Periodicals, Inc.)

Background: A new-generation everolimus eluting platinum-chromium stent (EePCS), offering improved radial strength, radiopacity and conformability compared to everolimus-eluting cobalt-chromium stents (EeCCS), was evaluated with regard to safety and efficacy in an all-comer cohort., Methods: A total of 1000 consecutive all-comer patients (including acute coronary syndrome, multivessel disease, calcified lesions) treated with an EePCS (Promus Premier™, Boston Scientific, Natick, Massachusetts) from May 2013 to October 2014 were compared to 1000 consecutive patients treated with an EeCCS (Xience Prime™, Abbott Vascular, Santa Clara, California) from April 2012 to May 2013. Patients were clinically followed for 1year., Results: Mean age was 66±12years with diabetes in 20.7%, previous infarction in 22.7%, and ACS as the indication in 71.2% of patients. The mean number of stents per patient was 1.8±1.13. Total stented length was 35±25mm. Lesion classification was B2/C in 73.9% of patients. At 1year the primary endpoint of major adverse cardiac events (all-cause mortality, myocardial infarction [MI], ischemia-driven target vessel revascularization [TVR]) was reached in 11.7% in the EePCS cohort and 10.9% in the EeCCS cohort (adjusted HR 1.01 [0.77-1.33]; p=0.95). No significant differences were noted in the individual clinical endpoints all-cause mortality (6.8% versus 6.4%), MI (2.2% versus 2.3%), and TVR (4.3% versus 3.7%) in the respective EePCS and EeCCS cohorts. Stent thrombosis occurred in 0.8% and 1.0% respectively., Conclusions: In all-comer patients undergoing percutaneous coronary intervention, the use of EePCS was associated with similar 1-year clinical outcome as compared to EeCCS., (Copyright © 2017 Elsevier B.V.

Background: Some aspects of prognosis are not reflected by cumulative survival estimates. These aspects include information on the time already survived by the patient and the patient's survival compared with the general population. Conditional survival (ie, conditional on having survived a certain period of time already) and relative conditional survival (ie, compared with the general population) do incorporate these aspects. We investigated these measures of prognosis in patients undergoing percutaneous coronary intervention., Methods and Results: We studied 17 903 consecutive patients undergoing percutaneous coronary intervention between 2000 and 2014. Cumulative survival was estimated for patients with ST-segment-elevation myocardial infarction (n=5996, 853 deaths), non-ST-segment-elevation myocardial infarction (n=5371, 901 deaths), and stable angina pectoris (n=6536, 965 deaths) in 4 age categories. One-year conditional and relative conditional survival up to 10 years post-percutaneous coronary intervention was calculated. The results demonstrated that 1-year cumulative survival for patients with ST-segment-elevation myocardial infarction aged ≥76 years was 83%. One-year conditional survival, conditional on surviving the first month, was 92% in this group, and relative conditional survival (relative to the general population) was 99%. In younger age categories and in patients with non-ST-segment-elevation myocardial infarction and stable angina pectoris , similar patterns were found albeit less pronounced. Five-year relative conditional rendered similar results., Conclusions: Relative conditional survival provides a comprehensive picture of patient prognosis, particularly for older patients with ST-segment-elevation myocardial infarction. Although, as expected, their cumulative survival is low, once they survive the first month after percutaneous coronary intervention, their prognosis is comparable to that of the general population. Therefore, relative conditional survival estimates provide an important, meaningful addition when discussing prognosis with patients., (© 2017 American Heart Association, Inc.)

Objectives: To assess whether the RXi Navvus system compared to the use of standard Fractional Flow Reserve (FFR) wires reduces total contrast volume, radiation and overall study cost in a real world patient population referred for coronary angiography or percutaneous coronary intervention., Background: FFR is the mainstay of functional hemodynamic assessment of coronary artery lesions. The RXi Navvus system (ACIST Medical Systems, Eden Prairie, MN) is a monorail microcatheter with FFR-measurement capability through optical pressure sensor technology., Methods: This is an investigator-initiated, prospective, single-center, observational cohort study. A total of 238 patients were enrolled, 97 patients with Navvus and 141 with conventional pressure-wire based FFR (PW-FFR). Final analyses were performed on the cohort in which only 1 device was used (82 Navvus procedures vs. 136 PW-FFR procedures)., Results: No significant differences were found in the total amount of contrast used (150±77 vs 147±79ml; p=0.81), radiation use (6200±4601 vs. 5076±4655 centiG∗cm 2 ; p=0.09) or costs (€1994,- vs. €1930,-; p=0.32) in the Navvus vs. PW-FFR groups respectively., Conclusions: No significant differences were found in the amount of contrast used, total procedural costs or radiation when the Navvus system was used as compared to conventional FFR wires., Condensed Abstract: CONTRACT is an investigator-initiated, prospective, single-center, observational cohort study that evaluated whether the RXi Navvus system compared to the use of standard Fractional Flow Reserve (FFR) wires reduces total contrast volume, radiation and overall study cost in a real world patient population referred for coronary angiography or percutaneous coronary intervention. Use of the RXi Navvus system was associated with comparable procedural costs, amount of radiation and contrast used as compared to PW-FFR systems., (Copyright © 2017 Elsevier Ireland Ltd.

Aims: Previous studies have reported the safety and feasibility of both time-domain optical coherence tomography (TD-OCT) and Fourier-domain OCT (FD-OCT) in highly selected patients and clinical settings. However, the generalizability of these data is limited, and data in unselected patient populations reflecting a routine cathlab practice are lacking. We compared safety of intracoronary FD-OCT imaging to intravascular ultrasound (IVUS) imaging in a large real-world series of consecutive patients who underwent invasive imaging during coronary catheterization in our centre., Methods and Results: This is a prospective, single-centre registry of patients scheduled for coronary angiography or intervention undergoing intracoronary imaging with FD-OCT or IVUS between April 2008 and December 2013. Intra-procedural and major in-hospital adverse events that could be possibly related to invasive imaging were registered routinely by the operator as part of our clinical report and prospectively recorded in our database. These events were retrospectively individually adjudicated by an independent safety committee. Between April 2008 and December 2013, 13 418 diagnostic or interventional coronary catheterization procedures were performed. Of these, 1142 procedures used OCT and 2476 procedures used IVUS. Invasive imaging-related complications were rare, did not differ between the two imaging methods (OCT: n = 7, 0.6%; IVUS: n = 12, 0.5%; P = 0.6), and were self-limiting after retrieval of the imaging catheter or easily treatable in the catheterization laboratory. No major adverse events, prolongation of hospital stay, or permanent patient harm was observed., Conclusion: FD-OCT is safe in an unselected and heterogeneous group of patients with varying clinical settings., (Published on behalf of the European Society of Cardiology.

Background: Cardiac rehabilitation (CR) is recommended as secondary prevention in primary percutaneous coronary intervention (pPCI) patients. This study was conducted to expand the knowledge about age-effects of CR in pPCI patients. The aim of this study was to compare changes in subjective health status (SHS) during and after CR between patients <60years and patients ≥60years, who underwent pPCI after myocardial infarction., Methods: Between 2009 and 2011, in total 282 pPCI patients who participated in CR were included. Patients completed the Short Form 12 (SF-12) questionnaire at baseline (pre-CR), 3months (post-CR) and 12months follow-up. Patients were divided into two age-groups, <60years versus ≥60years. To compare improvements in SHS between groups, Generalized Estimating Equations (GEE) analyses were performed., Results: The mean physical component summary (PCS) score improved over time in both groups and even reached mean levels of the normative Dutch population. The improvement on the PCS score was equal in both age groups. The mental component summary (MCS) score also improved in both groups. Patients <60years reported on average more improvement on the MCS score than patients ≥60years (Exp(B) 1.019; 95%CI 1.009-1.030; P<0.001). However, mean levels of the normative Dutch population were not reached by patients <60years., Conclusion: Even though pPCI patients <60years reported more improvement on the MCS score, mean levels of the normative Dutch population were not reached. Therefore, a tailored CR program with more focus on their mental status, may be beneficial in younger patients., (Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.)

Objective: The aim of this study was to investigate the psychosocial needs of both parents of children with CHD (aged 0-18 years) and patients themselves (aged 8-18 years) in the week before cardiac surgery or a catheter intervention. Patients Eligible participants included all consecutive patients (0-18 years) scheduled to undergo cardiac surgery or a catheter intervention in our hospital between March, 2012 and July, 2013. Psychosocial needs were assessed using a disease-specific questionnaire designed for this study, consisting of a 83-item parent version and a 59-item child version (for children ⩾8 years), each covering five domains: physical/medical, emotional, social, educational/occupational, and health behaviour; two items assessed from whom and in what format psychosocial care was preferred. Quality of life was also assessed. Interventions If parents/patients reported a need for psychosocial care, referral to adequate mental health-care professionals was arranged., Results: More than 40% of participating parents and >50% of participating children reported a need for psychosocial care on each of the five domains. Needs for psychosocial care for parents themselves were highest for those with children aged 0-12 years. Parents and patients report clear preferences when asked from whom and in what format they would like to receive psychosocial care. Quality of life was relatively high for both parents and patients. Psychosocial care interventions in our hospital increased significantly after the implementation of this study., Conclusions: Results show that psychosocial care is rated as (very) important by both parents and children during an extremely stressful period of their life.

Background: Poor subjective health status significantly predicted short-term mortality in patients with coronary artery disease (CAD). However, the relation between subjective health status and long-term mortality remains limited in patients treated with PCI. The aim of this study is to investigate the association between subjective health status and 14-year mortality in patients treated with percutaneous coronary intervention (PCI)., Methods: A consecutive cohort with 1111 patients treated for CAD who completed the SF-36 questionnaire was included between 2001 and 2002 as part of the RESEARCH registry., Results: After adjustment, physical functioning (HR: 1.96; 95% CI: 1.59-2.43), social functioning (HR: 1.53; 95% CI: 1.24-1.88), role limitations due to physical functioning (HR: 1.75; 95% CI: 1.41-2.16), role limitations due to emotional functioning (HR: 1.34; 95%CI: 1.08-1.67), mental health (HR: 1.52; 95% CI: 1.24-1.88), vitality (HR: 1.66; 95% CI: 1.35-2.03), bodily pain (HR: 1.63; 95% CI: 1.32-2.02) and general health (HR: 1.82; 95% CI: 1.49-2.23) were all associated with an increased risk of 14-year mortality., Conclusion: Physical and mental subjective health status as measured with the SF-36 appeared to be a strong predictor for 14-year mortality in post-PCI patients., (Copyright © 2016 Elsevier Ireland Ltd.

Objective: To provide prospective information on long-term outcome after surgical correction of valvular pulmonary stenosis (PS)., Methods: Fifty-three consecutive patients operated for PS during childhood between 1968 and 1980 in one centre are followed longitudinally for 37±3.4 years, including extensive in-hospital examination every 10 years., Results: Survival information was available in 100% of the original 53 patients. Cumulative survival was 94% at 20 years and 91% at 40 years. Excluding perioperative mortality (<30 days), survival was 94% at 40 years. Of 46 eligible survivors, 29 participated in the in-hospital examination and 15 gave permission to use their hospital records (96% participation). Cumulative event-free survival was 68% after 40 years: 25% needed a reintervention, 12% underwent pacemaker implantation and 9% had supraventricular arrhythmias. Early reinterventions were mainly for residual PS, late reinterventions for pulmonary regurgitation. Subjective health status was good. Exercise capacity was normal in 74% (median 96 (82-107)% of expected workload). Right ventricular and left ventricular (LV) dysfunction was found in 13% and 41%, respectively. The use of a transannular patch and younger age at surgery were predictive for late events (HR 3.02 (95% CI 1.09 to 8.37) and HR 0.81/year (95% CI 0.66 to 0.98), respectively). Use of inflow occlusion compared with cardiopulmonary bypass showed a trend towards more reinterventions (HR 3.19 (95% CI 0.97 to 10.47))., Conclusions: Survival up to 40 years after successful PS repair is nearly normal. Subjective health status is good and there is a low incidence of arrhythmias. Reinterventions, however, are necessary in one-quarter and 40 years postoperatively several patients show LV dysfunction., (Published by the BMJ Publishing Group Limited.

Background: Heart failure (HF) has a poor prognosis. Patients with acute heart failure in particular have a high risk of dying. However, there is a lack of data regarding their long-term mortality and changes there-in with time. The aim of our study was to describe trends in short- and long-term mortality of patients hospitalized with acute HF in the period from 1985 through 2008. In addition, we determined the prognostic worth of the aetiology of HF., Methods and Results: We included a consecutive series of 1810 patients with acute HF in this prospective registry in the period of 1985 through 2008. The cumulative one-year mortality rate of the patients was 35%. The short-term prognosis remained unchanged over the decades. However, the cumulative mortality rate ten years after admission was lowest in the last decade (73% in 2000-2008 vs. 78% in 1985-1999, p=0.001). After multivariable adjustment, the ten-year mortality rate was lower in the last decade as compared to the first decade (hazard ratio (HR) 0.83; 95% confidence interval (CI) 0.71-0.96). Ischemic cardiomyopathy was associated with a higher mortality (HR 1.32; 95% CI 1.12-1.54) when compared to other causes of HF., Conclusions: Patients admitted with acute HF were found to have both high short-term and long-term mortality. Long-term prognostic improvement in the last decade was observed among patients with a reduced ejection fraction. While patients with HF due to valvular heart disease had the best prognosis, an ischemic aetiology of HF was associated with the worst outcome., (Copyright © 2016 Elsevier Ireland Ltd.

The role of early coronary revascularization in the management of stable coronary artery disease remains controversial. The aim of this study was to evaluate the impact of early coronary revascularization on long-term outcomes (>10 years) after an ischemic dobutamine stress echocardiography (DSE) in patients with known or suspected coronary artery disease. Patients without stress-induced ischemia on DSE and those who underwent late coronary revascularization (>90 days after DSE) were excluded. The final study cohort consisted of 905 patients. A DSE with a peak wall motion score index of 1.1 to 1.7 was considered mild to moderately abnormal (n = 460), and >1.7 was markedly abnormal (n = 445). End points were all-cause and cardiac mortality. The impact of early coronary revascularization on outcomes was assessed using Kaplan-Meier survival analysis and Cox's proportional hazard regression models. Early coronary revascularization was performed in 222 patients (percutaneous coronary intervention in 113 [51%] and coronary artery bypass grafting in 109 patients [49%]). During a median follow-up time of 10 years (range 8 to 15), 474 deaths (52%) occurred, of which were 241 (51%) due to cardiac causes. Kaplan-Meier survival curves showed that both in patients with a markedly abnormal DSE and a mild-to-moderately abnormal DSE, early revascularization was associated with better long-term outcomes. Multivariable analyses revealed that early revascularization had a beneficial effect on all-cause mortality (hazard ratio 0.60, 95% confidence interval 0.46 to 0.79) and cardiac mortality (hazard ratio 0.49, 95% confidence interval 0.34 to 0.72). In conclusion, early coronary revascularization has a beneficial impact on long-term outcomes in patients with myocardial ischemia on DSE. Early coronary revascularization was associated with better outcomes not only in patients with a markedly abnormal DSE but also in those with a mild to moderately abnormal DSE., (Copyright © 2016 The Author(s).

Aims: Many studies have examined the prognostic value of myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) for the prediction of short- to medium-term outcomes. However, the long-term prognostic value of MPI in patients with diabetes mellitus remains unclear. Therefore, this study assessed the long-term prognostic value of MPI in a high-risk cohort of patients with diabetes mellitus., Methods and Results: A high-risk cohort of 207 patients with diabetes mellitus who were unable to undergo exercise testing underwent dobutamine stress MPI. Follow-up was successful in 206 patients; 12 patients were excluded due to early revascularization. The current data are based on the remaining 194 patients. Follow-up end points were all-cause mortality, cardiac mortality, and nonfatal myocardial infarction. The Kaplan-Meier survival curves were constructed, and univariable and multivariable analyses were performed to identify predictors of long-term outcome. During a mean follow-up of 8.1 ± 5.9 years, 134 (69%) patients died of which 68 (35%) died due to cardiac causes. Nonfatal myocardial infarction occurred in 24 patients (12%), and late (>60 days) coronary revascularization was performed in 61 (13%) patients. Survival analysis showed that MPI provided optimal risk stratification up to 4 years after testing. After that period, the outcome was comparable in patients with normal and abnormal MPI. Multivariable analyses showed that MPI provided incremental prognostic value up to 4 years after testing., Conclusion: In high-risk patients with diabetes mellitus, dobutamine MPI provides incremental prognostic information in addition to clinical data for a 4-year period after testing., (Published on behalf of the European Society of Cardiology.

Background: Low marital quality is associated with adverse health outcomes and lower personal well-being. Loneliness increases the risk of cardiovascular disease and mortality and predicts poor quality of life. The aim of this study was to investigate the association between marital quality and loneliness and subjective health status in primary percutaneous coronary intervention (pPCI) patients who underwent cardiac rehabilitation (CR)., Design/methods: In a prospective cohort study, pPCI patients that followed CR were included between 2009-2011. A total of 223 patients responded to the Short Form 12 (SF-12) (subjective health status), Maudsley Marital Questionnaire (MMQ-6) (marital quality) and University of California, Los Angeles - Revised (UCLA-R) questionnaires at baseline (pre-CR) and at three months (post-CR) or at 12 months follow-up. Subjective health status is displayed by a physical component summary (PCS) score and a mental component summary (MCS) score. Generalized estimating equation (GEE) analyses were performed to test improvements in subjective health status., Results: Changes over time in subjective health status scores were similar between patients with optimal marital quality vs patients with less optimal marital quality and non-lonely patients vs lonely patients. The MCS level at one-year follow-up of both patients with less optimal marital quality and lonely patients was lower compared with a healthy Dutch population (respectively; mean MCS score 47.3 (standard deviation (SD) 10.5); p = 0.013 and mean MCS score 46.1 (SD 11.2); p = 0.010)., Conclusion: Both patients with less optimal marital quality and lonely patients did not reach the MCS level of a healthy Dutch population. Therefore, extra care and support should be given to these patients in a CR programme., (© The European Society of Cardiology 2016.)

Aims: This study aimed to evaluate the prognostic value of high-sensitivity C-reactive protein (hsCRP) during 10-year follow-up after percutaneous coronary intervention (PCI)., Methods and Results: Between April and October 2002, hsCRP was measured in 468 all-comer patients who underwent PCI with sirolimus-eluting stent implantation for stable coronary artery disease or acute coronary syndrome. The primary endpoint was the composite of all-cause mortality or myocardial infarction at 10-year follow-up. Kaplan-Meier event curves displayed ongoing divergence of the hsCRP groups (hsCRP <1 mg/L: 14.7% vs. 1-3 mg/L: 31.1% vs. >3 mg/L: 43.1%). After adjustment for established cardiovascular risk factors and clinical presentation in a Cox regression model, higher CRP levels were associated with a higher incidence of the composite endpoint (>3 mg/L vs. <1 mg/L: HR 2.87, 95% CI: 1.69-4.87, p<0.001; 1-3 mg/L vs. <1 mg/L: HR 2.30, 95% CI: 1.31-4.03, p=0.004). Although adding hsCRP to a prediction model containing conventional cardiovascular risk factors did not significantly improve discriminatory power (area under the receiver operating characteristic curve 0.71 to 0.73, p=0.56), hsCRP was able to improve risk classification (net reclassification index=0.40, p=<0.001)., Conclusions: In patients undergoing PCI, higher CRP levels at the time of the procedure are predictive for 10-year mortality and myocardial infarction. High-sensitivity CRP may be a useful biomarker to improve further risk assessment in patients undergoing PCI.

The prognostic value of dobutamine stress echocardiography (DSE) at >10-year follow-up is unknown. The aim of this study was to assess the very long-term prognostic value of DSE in a high-risk cohort of patients with known or suspected coronary artery disease. This prospective, single-center study included 3,381 patients who underwent DSE from January 1990 to January 2003. Two-dimensional echocardiographic images were acquired at rest, during dobutamine stress, and during recovery. Follow-up events were collected and included overall mortality, cardiac death, nonfatal myocardial infarction, and revascularization. The incremental value of DSE in the prediction of selected end points was evaluated using multivariate Cox proportional hazard analysis. During a mean follow-up of 13 ± 3.2 years (range 7.3 to 20.5 years), there were 1,725 deaths (51%), of which 1,128 (33%) were attributed to cardiac causes. Patients with an abnormal DSE had a higher mortality rate (44% vs 35% at 15-year follow-up, p <0.001) than those with a normal DSE. When comparing echocardiographic variables at rest to variables at maximum dose dobutamine, the chi-square of the test improved from 842 to 870 (p <0.0001) and from 684 to 740 (p <0.0001) for all-cause mortality and cardiac death, respectively. DSE provided incremental value in predicting all-cause mortality, cardiac death, and hard cardiac events. There seems, however, to be a "warranty period" of approximately 7 years, when the survival curves of a normal and abnormal DSE no longer diverge., (Copyright © 2016 Elsevier Inc.

Aims: Early risk stratification is important in patients with cardiogenic shock from ST-elevation myocardial infarction (STEMI). We aimed to develop a simple risk chart that includes clinical parameters that are readily available at time of hospital admission to assess risk of 30-day mortality., Methods and Results: A series of 544 STEMI patients admitted to undergo primary percutaneous coronary intervention and presenting with cardiogenic shock were included between 2000 and 2012. Overall 30-day mortality was 38.4% and did not change over the years (p-trend=0.64). Baseline variables that were available at time of hospital admission were entered into a logistic regression model in a forward stepwise manner. Only age (odds ratio (OR) per year 1.05, 95% confidence interval (CI) 1.04-1.07, p<0.001), initial serum lactate level (OR per mmol/l 1.17, 95% CI 1.11-1.24, p<0.001) and initial creatinine level above the upper limit of normal (OR 2.89, 95% CI 1.90-4.37, p<0.001) remained independent predictors, and were subsequently used to develop a risk chart that stratifies risk of 30-day mortality into categories ranging from 0-20% to 80-100%. The calibration plot showed a close relationship between expected and observed mortality. The risk chart had a higher discriminative accuracy than the GRACE score (c-index 0.75 vs. 0.66, p=0.009). Adding variables that were obtained from coronary angiography and during clinical course did not significantly improve discriminative accuracy of risk chart (c-index 0.77, p=0.48)., Conclusion: Mortality of patients with cardiogenic shock from STEMI undergoing primary percutaneous coronary intervention can be well predicted already at time of hospital admission by a risk chart that uses only three variables, namely, age, initial serum lactate and creatinine level., (© The European Society of Cardiology 2015.)

Background: Subjective health status is an increasingly important parameter to assess the effect of percutaneous coronary intervention (PCI) in clinical practice. Aim of this study was to determine medical and psychosocial predictors of poor subjective health status over a 10 years' post-PCI period., Methods: We included a series of consecutive PCI patients (n = 573) as part of the RESEARCH registry, a Dutch single-center retrospective cohort study., Results: These patients completed the 36-item Short-Form Health Survey (SF-36) at baseline and 10 years post-PCI. We found 6 predictors of poor subjective health status 10 years post-PCI: SF-36 at baseline, age, previous PCI, obesity, acute myocardial infarction as indication for PCI, and diabetes mellitus (arranged from most to least numbers of sub domains)., Conclusions: SF-36 scores at baseline, age, and previous PCI were significant predictors of subjective health status 10 years post-PCI. Specifically, the SF-36 score at baseline was an important predictor. Thus assessment of subjective health status at baseline is useful as an indicator to predict long-term subjective health status. Subjective health status becomes better by optimal medical treatment, cardiac rehabilitation and psychosocial support. This is the first study determining predictors of subjective health status 10 years post-PCI.

Background: Depression has been shown to be an independent risk factor for short-term mortality in patients with coronary artery disease (CAD). There are studies suggesting that depression might also be associated with long-term mortality. Anxiety has also been associated with mortality. This study aimed to further investigate the predictive value of depression and anxiety symptoms on all-cause mortality, 10 years after percutaneous coronary intervention (PCI)., Methods: The study population comprised a consecutive series of CAD patients (n = 1411) treated with PCI between September 2001 and October 2002 at the Erasmus Medical Centre, Rotterdam. The Hospital Anxiety and Depression Scale (HADS) was completed by 1112 patients at baseline to assess levels of depression and anxiety. The endpoint was defined as all-cause mortality., Results: The prevalence of depression and anxiety was 24.8% and 27.7%, respectively. The cumulative all-cause mortality rate in depressed patients was 37% versus 20% in non-depressed patients (log-rank p < 0.001). After adjustment, depression remained a predictor of all-cause mortality (hazard ratio (HR) 1.77; 95% confidence interval (CI) 1.36-2.29). Cumulative survival rates did not differ for anxious versus non-anxious patients (log-rank p = .79). However, after adjustment, anxiety was associated with an increased risk for all-cause mortality (HR 1.50; 95% CI 1.14-1.98). A sub-analysis showed that cumulative survival rates did not differ for depressed and anxious patients versus depressed but non-anxious patients (log-rank p = 0.46)., Conclusions: Depression is associated with an increased risk of 77% for all-cause mortality, 10 years post-PCI, independently of anxiety. Although anxiety was associated with all-cause mortality, it has no additional value in the case of co-occurring depression., (© The European Society of Cardiology 2015.)

Objective: To determine longitudinal changes in psychopathology in a cohort of patients 30-43 years after their first cardiac surgery for Congenital Heart Disease (CHD) in childhood, to compare outcomes of the 30- to 43-year follow-up with normative data, and to identify medical predictors for psychopathology., Methods: This study is the third follow-up of this cohort. The first and second follow-ups of this same cohort were conducted in 1990 and 2001, respectively. At all three follow-ups, psychopathology was assessed with standardised, parallel questionnaires. In 2011, subjective health status was assessed by the Short Form-36. Medical predictor variables were derived from medical examinations and medical records., Results: In this third follow-up, a total of 252 patients participated. Of these, 152 patients participated in all three follow-ups. Over a 30-year period, proportions of patients showing psychopathology decreased significantly. At the 30- to 43-year follow-up, overall outcomes on psychopathology for the CHD sample were similar or even better compared with normative groups. Subjective health status was also better compared with normative data. No differences were found between cardiac diagnostic groups. Medical variables that predicted the course of psychopathology over time were as follows: the scar, as judged by the patient, results of the first cardiac surgery, and the number of hospitalisations., Conclusions: Over a 30-year period, psychopathology decreased in patients with CHD. Levels of psychopathology in these patients, who are now aged between 30 and 54 years, were comparable or even better than normative data.
