Evidence about the effectiveness and safety of dog visits in pediatric oncology is limited. We conducted a randomized controlled trial (n=26) of dog visits versus usual care among pediatric oncology inpatients. Psychological functioning and microbial load from hand wash samples were evaluated. Parental anxiety was a secondary outcome. We did not observe a difference in the adjusted mean present functioning score (−3.0; 95% confidence interval [CI], −12.4 to 6.4). The difference in microbial load on intervention versus control hands was −0.04 (95% CI, −0.60 to 0.52) log10 CFU/mL, with an upper 95% CI limit below the prespecified noninferiority margin. Anxiety was lower in parents of intervention versus control patients. We did not detect an effect of dog visits on functioning; however, our study was underpowered by low recruitment. Visits improved parental anxiety. With hand sanitization, visits did not increase hand microbial levels. Clinicaltrials.gov NCT03471221. [ABSTRACT FROM AUTHOR]

• This analysis reports the effects of intravenous ferric derisomaltose (FDI) in a population of patients with heart failure and iron deficiency anemia in the IRONMAN trial. • Intravenous FDI was well-tolerated and improved quality of life and may reduce morbidity and mortality in patients with heart failure, anemia, and iron deficiency. • This will help shared decision-making in the management of patients with heart failure in countries where intravenous FDI is only licensed for the treatment of iron deficiency when accompanied by anemia. In some countries, intravenous ferric derisomaltose (FDI) is only licensed for treating iron deficiency with anemia. Accordingly, we investigated the effects of intravenous FDI in a subgroup of patients with anemia in the IRONMAN (Effectiveness of Intravenous (IV) Iron Treatment Versus Standard Care in Patients With Heart Failure and Iron Deficiency) trial. IRONMAN enrolled patients with heart failure, a left ventricular ejection fraction of ≤45%, and iron deficiency (ferritin <100 µg/L or transferrin saturation of <20%), 771 (68%) of whom had anemia (hemoglobin <12 g/dL for women and <13 g/dL for men). Patients were randomized, open label, to FDI (n = 397) or usual care (n = 374) and followed for a median of 2.6 years. The primary end point, recurrent hospitalization for heart failure and cardiovascular death, occurred less frequently for those assigned to FDI (rate ratio 0.78, 95% confidence interval 0.61–1.01; P =.063). First event analysis for cardiovascular death or hospitalization for heart failure, less affected by the coronavirus disease 2019 pandemic, gave similar results (hazard ratio 0.77, 95% confidence interval 0.62–0.96; P =.022). Patients randomized to FDI reported a better Minnesota Living with Heart Failure quality of life, for overall (P =.013) and physical domain (P =.00093) scores at 4 months. In patients with iron deficiency anemia and heart failure with reduced left ventricular ejection fraction, intravenous FDI improves quality of life and may decrease cardiovascular events.

The authors used the BCIS (British Cardiovascular Intervention Society) database to define the factors associated with percutaneous coronary intervention (PCI) procedural complexity. Complex high-risk indicated percutaneous coronary intervention (CHIP-PCI) is an emerging concept that is poorly defined. The BCIS (British Cardiovascular Intervention Society) database was used to study all PCI procedures in the United Kingdom 2006-2016. A multiple logistic regression model was developed to identify variables associated with in-hospital major adverse cardiac or cerebrovascular events (MACCE) and to construct a CHIP score. The cumulative effect of this score on patient outcomes was examined. A total of 313,054 patients were included. Seven patient factors (age ≥80 years, female sex, previous stroke, previous myocardial infarction, peripheral vascular disease, ejection fraction <30%, and chronic renal disease) and 6 procedural factors (rotational atherectomy, left main PCI, 3-vessel PCI, dual arterial access, left ventricular mechanical support, and total lesion length >60 mm) were associated with increased in-hospital MACCE and defined as CHIP factors. The mean CHIP score/case for all PCIs increased significantly from 1.06 ± 1.32 in 2006 to 1.49 ± 1.58 in 2016 (P < 0.001 for trend). A CHIP score of 5 or more was present in 2.5% of procedures in 2006 increasing to 5.3% in 2016 (P < 0.001 for trend). Overall in-hospital MACCE was 0.6% when the CHIP score was 0 compared with 1.2% with any CHIP factor present (P < 0.001). As the CHIP score increased, an exponential increase in-hospital MACCE was observed. The cumulative MACCE for procedures associated with a CHIP score 4+ or above was 3.2%, and for a CHIP score 5+ was 4.4%. All other adverse clinical outcomes were more likely as the CHIP score increased. Seven patient factors and 6 procedural factors were associated with adverse in-hospital MACCE and defined as CHIP factors. Use of a CHIP score might be a future target for risk modification.

The aims of this study were to use a national percutaneous coronary intervention (PCI) registry to study temporal changes in procedure volumes of PCI using rotational atherectomy (ROTA-PCI), the patient and procedural factors associated with differing quartiles of operator ROTA-PCI volume, and the relationship between operator ROTA-PCI volumes and in-hospital patient outcomes. Whether higher operator volume is associated with improved outcomes after ROTA-PCI is poorly defined. Data from the British Cardiovascular Intervention Society national PCI database were analyzed for all ROTA-PCI procedures performed in the United Kingdom between 2013 and 2016. Individual logistic regressions were performed to quantify the independent association between annual operator ROTA-PCI volume and in-hospital outcomes. In total, 7,740 ROTA-PCI procedures were performed, with a negatively skewed distribution and an annualized operator volume median of 2.5 procedures/year (range 0.25 to 55.25). Higher volume operators undertook more complex procedures in patients with greater comorbid burdens than lower volume operators. A significant inverse association was observed between operator ROTA-PCI volume and in-hospital mortality (odds ratio [OR]: 0.986/case; 95% confidence interval [CI]: 0.975 to 0.996; p = 0.007) and major adverse cardiac and cerebral events (OR: 0.983/case; 95% CI: 0.975 to 0.993; p < 0.001). Additionally, lower rates of emergency cardiac surgery (OR: 0.964/case; 95% CI: 0.939 to 0.991; p = 0.008), arterial complications (OR: 0.975/case; 95% CI: 0.975 to 0.982; p < 0.001) and in-hospital major bleeding (OR: 0.985/case; 95% CI: 0.977 to 0.993; p < 0.001) were associated with higher ROTA-PCI operator volume. Sensitivity analyses in several subgroups demonstrated a consistency of improved outcomes as annual ROTA-PCI volume increased. An annual volume of <4 ROTA-PCI procedures/year was observed to be associated with increased major adverse cardiac and cerebral events, with 239 of 432 operators (55%) not exceeding this threshold. In-hospital adverse outcomes occurred less frequently as ROTA-PCI operator volume increased. These data suggest that operator volume is an important factor determining outcome after ROTA-PCI.

Background: Complex high-risk and indicated revascularization using percutaneous coronary intervention (CHIP-PCI) is an emerging concept that is poorly studied.Objective: To define temporal changes in CHIP-PCI volumes, and the relationship between operator CHIP-PCI volume and patient outcomes.Methods and Results: Data were analyzed on all CHIP-PCI procedures undertaken for stable angina in England and Wales between 2007 and 2014. Operator volume data was available for 2012-14. CHIP-PCI was defined by patient characteristics (age ≥80years, left ventricular (LV) ejection fraction <30%, previous CABG, or chronic renal failure) and/or by procedural characteristics (left main PCI, chronic total occlusion PCI, LV support, use of rotational atherectomy or laser atherectomy). CHIP-PCI as a percentage of total PCI increased from 28.1% in 2007 to 36.2% in 2014 (P < .001). Between 2012 and 2014, a total of 30,268 CHIP-PCI cases were performed. Total operator volume varied from 1 to 580 cases with median total operator volume of 29 cases. Higher operator volumes were associated with a greater degree of patient comorbidity and increasing procedural complexity. After adjustment for baseline difference, in-hospital major bleeding (P < .001 for trend), access site complications (P < .001) and coronary perforation (P = .002) were associated with increasing operator CHIP-PCI volumes. However, the frequency of in-hospital death (P = .394) and 12-month mortality (P = .638) were similar across the volume quartiles. Higher volumes quartiles were associated with a greater likelihood of same day discharge (P < .001).Conclusions: CHIP-PCI cases are an increasingly large population in contemporary PCI practice. Higher operator volumes were not associated with improved 12-month survival.Condensed Abstract: Data were analyzed on all complex high-risk and indicated revascularization using percutaneous coronary intervention (CHIP-PCI) procedures in England and Wales between 2007 and 2014. CHIP-PCI as a percentage of total PCI increased from 28.1% in 2007 to 36.2% in 2014 (P < .001). Median total operator volume was 29 cases with higher volumes associated with more patient comorbidity and increasing procedural complexity. In-hospital major bleeding (P < .001 for trend), access site complications (P < .001) and coronary perforation (P = .002) all associated with increasing operator CHIP-PCI volumes. However, trends for in-hospital death (P = .394), and 12-month mortality (P = .638) were similar across the volume quartiles. [ABSTRACT FROM AUTHOR]

We assessed the effects of opioid dose and risk reduction initiatives on opioid overdose rates among patients on chronic opioid therapy (COT). Using an interrupted time series design, we compared trends in overdose rates. We compared patients on COT in settings that implemented a COT dose reduction initiative and then a COT risk stratification/monitoring initiative to similar patients on COT from control settings. From 2006 to 2014, 31,142 patients on COT (22,673 intervention, 8,469 control) experienced 311 fatal or nonfatal opioid overdoses. In primary analyses, changes in opioid overdose rates among patients on COT did not differ significantly between intervention and control settings with the implementation of either dose reduction or risk stratification/monitoring. In planned secondary analyses, overdose rates decreased significantly (17% per year) during the dose reduction initiative among patients on COT in intervention settings (relative annual change, 0.83; 95% confidence interval, 0.70-0.99), but not in control settings (0.98. 95% confidence interval, 0.70-1.39). We conclude that overdose rates among patients on COT were not decreased by risk stratification and monitoring initiatives. Results were inconsistent for COT dose reduction, with no significant difference between intervention and control settings (primary hypothesis test), but a significant decrease in overdose rates within the intervention setting during dose reduction (secondary hypothesis test). PERSPECTIVE: Risk stratification/monitoring interventions among patients on COT did not decrease opioid overdose rates. The effects of COT dose reduction on opioid overdose rates were inconsistent. Greater decreases in COT dose, a larger control group, or both may have been needed to identify conclusive reductions in opioid overdose rates. [ABSTRACT FROM AUTHOR]

Objectives The authors sought to determine the relationships between left radial access (LRA) or right radial access (RRA) and clinical outcomes using the British Cardiovascular Intervention Society (BCIS) database. Background LRA has been shown to offer procedural advantages over RRA in percutaneous coronary intervention (PCI) although few data exist from a national perspective around its use and association with clinical outcomes. Methods The authors investigated the relationship between use of LRA or RRA and clinical outcomes of in-hospital or 30-day mortality, major adverse cardiovascular events (MACE), in-hospital stroke, and major bleeding complications in patients undergoing PCI between 2007 and 2014. Results Of 342,806 cases identified, 328,495 (96%) were RRA and 14,311 (4%) were LRA. Use of LRA increased from 3.2% to 4.6% from 2007 to 2014. In patients undergoing a repeat PCI procedure, the use of RRA dropped to 72% at the second procedure and was even lower in females (65%) and patients >75 years of age (70%). Use of LRA (compared with RRA) was not associated with significant differences in in-hospital mortality (odds ratio [OR]: 1.19, 95% confidence interval [CI]: 0.90 to 1.57; p = 0.20), 30-day mortality (OR: 1.17, 95% CI: 0.93 to 1.74; p = 0.16), MACE (OR: 1.06, 95% CI: 0.86 to 1.32; p = 0.56), or major bleeding (OR: 1.22, 95% CI: 0.87 to 1.77; p = 0.24). In propensity match analysis, LRA was associated with a significant decrease in in-hospital stroke (OR: 0.52, 95% CI: 0.37 to 0.82; p = 0.005). Conclusions In this large PCI database, use of LRA is limited compared with RRA but conveys no increased risk of adverse outcomes, but may be associated with a reduction in PCI-related stroke complications.

Aims: Access site choice for cases requiring rotational atherectomy (PCI-ROTA) is poorly defined. Using the British Cardiovascular Intervention Society PCI database, temporal changes and contemporary associates/outcomes of access site choice for PCI-ROTA were studied.Methods and Results: Data were analysed from 11,444 PCI-ROTA procedures performed in England and Wales between 2007 and 2014. Multivariate logistic regression was used to identify predictors of access site choice and its association with outcomes.Results: For PCI-ROTA, radial access increased from 19.6% in 2007 to 58.6% in 2014. Adoption of radial access was slower in females, those with prior CABG, and in patients with chronic occlusive (CTO) or left main disease. In 2013/14, the strongest predictors of femoral artery use were age (OR 1.02, [1.005-1.036], P = .008), CTO intervention (OR 1.95, [1.209-3.314], P = .006), and history of previous CABG (OR 1.68, [1.124-2.515], P = .010). Radial access was associated with reductions in overall length of stay, and increased rates of same-day discharge. Procedural success rates were similar although femoral access use was associated with increased access site complications (2.4 vs. 0.1%, P < .001). After adjustment for baseline differences, arterial complications (OR 15.6, P < .001), transfusion (OR 12.5, P = .023) and major bleeding OR 6.0, P < .001) remained more common with FA use. Adjusted mortality and MACE rates were similar in both groups.Conclusions: In contemporary practice, radial access for PCI-ROTA results in similar procedural success when compared to femoral access but is associated with shorter length of stay, and lower rates of vascular complication, major bleeding and transfusion.

Dose reduction and risk mitigation initiatives have been recommended to reduce opioid-related risks among patients receiving chronic opioid therapy (COT), but questions remain over whether these initiatives worsen pain control and quality of life. In 2014 to 2015, we interviewed 1,588 adult COT patients within a health care system in Washington State and compared those who received dose reduction and risk mitigation initiatives in primary care clinics (intervention) with patients in comparable health care settings without initiatives (control). The primary outcomes were pain assessed using the pain, enjoyment, and general activity (PEG) scale, a 3-item scale to assess global pain intensity and interference, with secondary measures including depression (Patient Health Questionnaire-8 scale). Generalized estimating equations for linear regression models were used to estimate differences in mean scores between intervention and control sites. Estimated differences, adjusted for patient characteristics and weighted for nonresponse, between patients at intervention and control clinics were not clinically significant for the PEG (-.03, 95% confidence interval = -.25 to .19) or Patient Health Questionnaire-8 (-.64, 95% confidence interval = -1.19 to -.08). We found no evidence that COT patients in clinics with dose reduction and risk mitigation initiatives had clinically meaningful differences in pain intensity, interference with activities and enjoyment of life, or depressive symptoms compared with control health care settings.Perspective: This article evaluates the effect of dose reduction and risk mitigation initiatives, such as those recently recommended by the Centers for Disease Control and Prevention, to reduce risks associated with COT on global pain and interference, depressive symptoms, and perceived pain relief and bothersomeness of side effects.

Objectives This study sought to examine the relationship between access site practice and clinical outcomes in patients requiring percutaneous coronary intervention (PCI) following thrombolysis for ST-segment elevation myocardial infarction (STEMI). Background Transradial access (TRA) is associated with better outcomes in patients requiring PCI for STEMI. A significant proportion of STEMI patients may receive thrombolysis before undergoing PCI in many countries across the world. There are limited data around access site practice and its associated outcomes in this cohort of patients. Methods The author used the British Cardiovascular Intervention Society dataset to investigate the outcomes of patients undergoing PCI following thrombolysis between 2007 and 2014. Patients were divided into TRA and transfemoral access groups depending on the access site used. Multiple logistic regression and propensity score matching were used to study the association of access site with in-hospital and long-term mortality, major bleeding, and access site–related complications. Results A total of 10,209 patients received thrombolysis and PCI during the study time. TRA was used in 48% (n = 4,959) of patients; 3.3% (n = 336) patients died in hospital, 1.6% (n = 165) of patients experienced major bleeding, 4.2% (n = 437) experienced major adverse cardiac events (MACE), and 4.6% (n = 468) experienced 30-day mortality. After multivariate adjustment, TRA was associated with significantly reduced odds of in-hospital mortality (odds ratio [OR]: 0.59; 95% confidence interval [CI]: 0.42 to 0.83; p = 0.002), major bleeding (OR: 0.45; 95% CI: 0.31 to 0.66; p < 0.001), MACE (OR: 0.72; 95% CI: 0.55 to 0.94; p = 0.01), and 30-day mortality (OR: 0.72; 95% CI: 0.55 to 0.94; p = 0.01). Conclusions TRA is associated with decreased odds of bleeding complications, mortality, and MACE in patients undergoing PCI following thrombolysis and should be preferred access site choice in this cohort of patients.

Purpose Safe firearm storage practices are associated with a lower risk of self-inflicted injury and death. Whether such practices and relevant beliefs differ between households of adolescents with and without mental illness is unknown. Methods We used survey and administrative data to perform a two-stage cross-sectional study of parents/guardians of adolescents who were 11–17 years, enrolled in a managed care plan in 2004 and living in a household with a firearm. Multivariable Poisson models compared the prevalence of three firearm storage practices between households of adolescents with (depression or bipolar disorder) and without mental illness (no psychiatric or substance use disorder), including whether all firearms were locked, any firearms were loaded, and all firearms were locked and unloaded. We used chi-square tests to compare responses to Likert items assessing beliefs relevant to storage practices between households. Results Adolescents with mental illness were present in 141 (50.5%) of 279 study households. Their mean age was 14.5 years, and 54.8% were male. The mean age of parent/guardian respondents was 47.0 years, and 17.9% were male. Respondents from nearly 70% of households reported that all household firearms were stored locked and unloaded. In unadjusted and adjusted analyses, there were no significant differences in the prevalence of three firearm storage practices or in beliefs relevant to those practices between households of adolescents with and without mental illness. Conclusions These findings add to a growing body of evidence suggesting that firearm storage practices do not differ based on household mental health risk factors for self-harm.

Objectives This study sought to determine the risk factors for post-transcatheter aortic valve replacement (TAVR) dialysis and to determine the impact of pre-TAVR or post-TAVR dialysis on mortality. Background TAVR is now established as an alternative treatment to surgical aortic valve replacement. Data examining the impact of dialysis on outcomes after TAVR are lacking. Methods The UK TAVI (Transcatheter Aortic Valve Implantation) Registry was established to report outcomes on all TAVR procedures performed within the United Kingdom (2007 to 2014). Data were collected prospectively on 6,464 patients with a median follow-up of 625 days. Results The proportion of patients on dialysis before TAVR has remained constant at 1.8%. After TAVR, the proportion of patients newly needing dialysis after TAVR has fallen from 6.1% (2007 to 2008) to 2.3% (2013 to 2014). The risk of new dialysis requirement after TAVR was independently associated with lower baseline renal function, year of procedure, impaired left ventricular function, diabetes, use of an Edwards valve, a nontransfemoral approach, need for open surgery, and moderate-to-severe aortic regurgitation after the procedure. Requirement for new dialysis after TAVR was associated with higher mortality at 30 days (hazard ratio: 6.44; 95% confidence interval: 4.87 to 8.53) and at 4 years (hazard ratio: 3.54; 95% confidence interval: 2.99 to 4.19; p < 0.001 for all) compared with patients without dialysis requirement. Conclusions The proportion of patients needing dialysis after TAVR has decreased over time. Post-TAVR dialysis is associated with increased mortality. Factors identified with dialysis requirement after TAVR require further investigation. [ABSTRACT FROM AUTHOR]

Objectives The aims of this study were to examine the relationship between body mass index (BMI) and clinical outcomes following percutaneous coronary intervention (PCI) and to determine the relevance of different clinical presentations requiring PCI to this relationship. Background Obesity is a growing problem, and studies have reported a protective effect from obesity compared with normal BMI for adverse outcomes after PCI. Methods Between 2005 and 2013, 345,192 participants were included. Data were obtained from the British Cardiovascular Intervention Society registry, and mortality data were obtained through the U.K. Office of National Statistics. Multiple logistic regression was performed to determine the association between BMI group (<18.5, 18.5 to 24.9, 25 to 30 and >30 kg/m 2 ) and adverse in-hospital outcomes and mortality. Results At 30 days post-PCI, significantly lower mortality was seen in patients with elevated BMIs (odds ratio [OR]: 0.86 [95% confidence interval (CI): 0.80 to 0.93] 0.90 [95% CI: 0.82 to 0.98] for BMI 25 to 30 and >30 kg/m 2 , respectively). At 1 year post-PCI, and up to 5 years post-PCI, elevated BMI (either overweight or obese) was an independent predictor of greater survival compared with normal weight (OR: 0.70 [95% CI: 0.67 to 0.73] and 0.73 [95% CI: 0.69 to 0.77], respectively, for 1 year; OR: 0.78 [95% CI: 0.75 to 0.81] and 0.88 [95% CI: 0.84 to 0.92], respectively, for 5 years). Similar reductions in mortality were observed for the analysis according to clinical presentation (stable angina, unstable angina or non–ST-segment elevation myocardial infarction, and ST-segment elevation myocardial infarction). Conclusions A paradox regarding the independent association of elevated BMI with reduced mortality after PCI is still evident in contemporary U.K. practice. This is seen in both stable and more acute clinical settings. [ABSTRACT FROM AUTHOR]

Objectives The aim of this study was to assess, using a national percutaneous coronary intervention (PCI) database, access-site choice and outcomes after chronic total occlusion (CTO) PCI. Background Given the influence of access site on outcomes, the use of radial access in CTO PCI warrants further investigation. Methods Data were analyzed from the British Cardiovascular Intervention Society dataset of 26,807 elective CTO PCI procedures performed in England and Wales between 2006 and 2013. Multivariate logistic regression was used to identify predictors of access-site choice and its association with outcomes. Results There was a significant decrease in femoral artery (FA) access from 84.6% in 2006 to 57.9% in 2013. Procedural factors associated with FA access included dual access (odds ratio [OR]: 3.89; 95% confidence interval [CI]: 3.45 to 4.32), CrossBoss/Stingray (OR: 1.87; 95% CI: 1.43 to 2.12), intravascular ultrasound (OR: 1.32; 95% CI: 1.21 to 1.53), and microcatheter use (OR: 1.18; 95% CI: 1.03 to 1.39). There was an association between FA access and the number of CTO devices used (p = 0.001 for trend). Access-site complications (1.5% vs. 0.5%; p < 0.001), periprocedural myocardial infarction (0.5% vs. 0.2%; p = 0.037), major bleeding (0.8% vs. 0.2%, p < 0.001), transfusion (0.4% vs. 0%; p < 0.001), and 30-day death (0.6% vs. 0.1%; p = 0.002) were more frequent in patients undergoing CTO PCI using FA access. An access-site complication during CTO PCI was associated with significant increases in transfusion (8.0% vs. 0.1%; p < 0.001), procedural coronary complication (17.3% vs. 5.8%; p < 0.0001), major bleeding (8.4% vs. 0.3%; p < 0.001), and mortality at all time points. Conclusions FA access remains predominant during CTO PCI, with case complexity and device size associated with its use. Access-site complications were more frequent with FA use and strongly correlated with adverse outcomes. [ABSTRACT FROM AUTHOR]

Background: The performance of emerging transcatheter aortic valve implantation (TAVI) clinical prediction models (CPMs) in national TAVI cohorts distinct from those where they have been derived is unknown. This study aimed to investigate the performance of the German Aortic Valve, FRANCE-2, OBSERVANT and American College of Cardiology (ACC) TAVI CPMs compared with the performance of historic cardiac CPMs such as the EuroSCORE and STS-PROM, in a large national TAVI registry.Methods: The calibration and discrimination of each CPM were analyzed in 6676 patients from the UK TAVI registry, as a whole cohort and across several subgroups. Strata included gender, diabetes status, access route, and valve type. Furthermore, the amount of agreement in risk classification between each of the considered CPMs was analyzed at an individual patient level.Results: The observed 30-day mortality rate was 5.4%. In the whole cohort, the majority of CPMs over-estimated the risk of 30-day mortality, although the mean ACC score (5.2%) approximately matched the observed mortality rate. The areas under ROC curve were between 0.57 for OBSERVANT and 0.64 for ACC. Risk classification agreement was low across all models, with Fleiss's kappa values between 0.17 and 0.50.Conclusions: Although the FRANCE-2 and ACC models outperformed all other CPMs, the performance of current TAVI-CPMs was low when applied to an independent cohort of TAVI patients. Hence, TAVI specific CPMs need to be derived outside populations previously used for model derivation, either by adapting existing CPMs or developing new risk scores in large national registries.

Objectives: To quantify and study the distribution of innervation of the left atrium and the pulmonary veins in humans. Background: Damage to cardiac nerves has been hypothesized as the explanation for successful radiofrequency ablation of atrial fibrillation. Methods: From January 2003 to September 2003, histologic and quantitative studies of innervation of the left atrium and the pulmonary veins was performed in 43 consecutive necropsied adult hearts (30 men and 3 women; mean age 45.5 ± 12.4 years). The left atrium was sectioned in 1-cm slices from left to right, with the plane of section perpendicular to the long axis of the heart. Sections of the pulmonary veins at their ostia and sections 1 cm away of this structure also were obtained. Nerve fiber density was counted manually for each case and expressed as the mean number per slice. Results: Numerous epicardial nerve fibers and ganglia having distinct patterns of distribution in the left atrium were found. Nerve density was significantly higher at the ostia of the four pulmonary veins than in their distal part (7.1 ± 2.1 vs 5.2 ± 1.3 for left upper pulmonary vein; 6.3 ± 1.5 vs 5.2 ± 1.7 for right upper pulmonary vein; 7.4 ± 2 vs 5.9 ± 2 for left lower pulmonary vein; 6.7 ± 1.8 vs 3.9 ± 1.3 for right lower pulmonary vein). The left superior vein was significantly more innervated than the right inferior vein (12.3 ± 3 vs 10.6 ± 1.4). Gradients of innervation were found from right to left (9.8 ± 4.6 vs 18.5 ± 6.6, P &#60; .05) and from the front to the rear of the atrium (17.2 ± 6.4 vs 20.7 ± 6.5, P &#60; .05). The same heterogeneous distribution was observed at the myocardial level but with thinner nerve fibers, making quantification difficult. Only very thin nerve fibers were present in the endocardium. Conclusions: The human left atrium exhibits several gradients of innervation at discrete sites. These findings may have clinical implications for radiofrequency ablation of atrial fibrillation.

Objectives This study used a large national cohort to examine patterns of thrombectomy use in ST-segment elevation myocardial infarction (STEMI) and the relationship to mortality. Background The impact of coronary thrombectomy on mortality in STEMI has not been definitively established. Published trial data have been insufficiently powered to address this. Methods The U.K. national registry was used to study 98,176 patients treated with primary percutaneous coronary intervention (PCI), between January 1, 2006, and December 31, 2013. Patients were grouped on the basis of whether they received thrombectomy or not; subgroups of simple (manual aspiration) and complex (mechanical) thrombectomy were also evaluated. The primary endpoint was 30-day mortality. The principal adjusted analysis used propensity score matching (PSM). A sensitivity analysis was performed using logistic regression controlled for the propensity score. Results Thrombectomy use markedly increased in the United Kingdom between 2008 and 2010 but plateaued thereafter at slightly below 50% of all primary PCI cases. No significant mortality difference was seen, in adjusted analyses, between the overall thrombectomy group and the no thrombectomy group, at 30 days or 1 year (at 30 days, PSM average treatment effect [ATE] coefficient 0.0028, 95% confidence interval: −0.0048 to 0.0104; p = 0.47). Likewise, no difference was seen between the simple (manual) thrombectomy versus no thrombectomy, at either time point (at 30 days, PSM ATE coefficient 0.0007, 95% confidence interval: −0.0049 to 0.0063; p = 0.80). By contrast, the complex (mechanical) thrombectomy group demonstrated a significantly higher mortality than the no thrombectomy group at 1-year follow-up (PSM ATE coefficient 0.0434, 95% confidence interval: 0.0081 to 0.0786; p = 0.017). Conclusions Coronary thrombectomy was not associated with lower mortality in primary PCI for STEMI when used in our large all-comer cohort in a selective manner on the basis of physician judgment. These findings are consistent with other negative clinical outcomes in recent large randomized controlled trials studying routine manual thrombectomy in primary PCI. [ABSTRACT FROM AUTHOR]

Objectives The U.K. Transcatheter Aortic Valve Implantation Registry reported 30-day and 1-year mortality rates of 7.1% and 21.4%, respectively, for patients who underwent transcatheter aortic valve replacement (TAVR) in the United Kingdom between 2007 and 2009. The study aim was to report long-term outcomes in this same cohort of patients. Background There are few data on outcomes beyond 3 years after TAVR in any notable number of patients. Methods Data from all TAVR procedures performed in the United Kingdom between January 2007 and December 2009 were prospectively collected. All-cause mortality status was reported in March 2014. Mortality tracking was achieved in 97.7% patients. Results The minimal time from replacement to census was 4.1 years, and the maximal time was 7.0 years. The 3- and 5-year survival rates were 61.2% and 45.5%, respectively. Independent predictors of 3-year mortality were renal dysfunction (hazard ratio [HR]: 1.65), atrial fibrillation (HR: 1.36), logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) ≥18.5 (HR: 1.33), respiratory dysfunction (HR: 1.28), and ventricular dysfunction (left ventricular ejection fraction <30%) (HR: 1.53). Coronary artery disease (HR: 1.28) and age (HR: 1.03) were additional independent predictors of mortality at 5 years. Stroke within 30 days of TAVR was the only independent procedural predictor of mortality at 3 and 5 years (HR: 2.17 at 3 years). Device type, access route, and paravalvular leak did not independently predict long-term outcome. Conclusions In the large U.K. Transcatheter Aortic Valve Implantation Registry, long-term outcomes after TAVR are favorable with 3- and 5-year survival rates of 61.2% and 45.5%, respectively. Long-term survival after TAVR is largely determined by intrinsic patient factors. Other than stroke, procedural variables, including paravalvular aortic leak, did not appear to be independent predictors of long-term survival. [ABSTRACT FROM AUTHOR]

OBJECTIVES: This study sought to define the prevalence and prognostic impact of blood transfusions in contemporary percutaneous coronary intervention (PCI) practice. BACKGROUND: Although the presence of anemia is associated with adverse outcomes in patients undergoing PCI, the optimal use of blood products in patients undergoing PCI remains controversial. METHODS: A search of EMBASE and MEDLINE was conducted to identify PCI studies that evaluated blood transfusions and their association withmajor adverse cardiac events (MACE) andmortality. Two independent reviewers screened the studies for inclusion, and data were extracted from relevant studies. Random effects meta-analysis was used to estimate the risk of adverse outcomes with blood transfusions. Statistical heterogeneity was assessed by considering the I² statistic. RESULTS: Nineteen studies that included 2,258,711 patients with more than 54,000 transfusion events were identified (prevalence of blood transfusion 2.3%). Crude mortality rate was 6,435 of 50,979 (12.6%, 8 studies) in patients who received a blood transfusion and 27,061 of 2,266,111 (1.2%, 8 studies) in the remaining patients. Crude MACE rates were 17.4% (8,439 of 48,518) in patients who had a blood transfusion and 3.1% (68,062 of 2,212,730) in the remaining cohort. Meta-analysis demonstrated that blood transfusion was independently associated with an increase in mortality (odds ratio: 3.02, 95% confidence interval: 2.16 to 4.21, I² = 91%) and MACE (odds ratio: 3.15, 95% confidence interval: 2.59 to 3.82, I² = 81%). Similar observations were recorded in studies that adjusted for baseline hematocrit, anemia, and bleeding. CONCLUSIONS: Blood transfusion is independently associated with increased risk of mortality and MACE events. Clinicians should minimize the risk for periprocedural transfusion by using available bleeding-avoidance strategies and avoiding liberal transfusion practices. [ABSTRACT FROM AUTHOR]

Objectives This study sought to determine the relationships among access site practice, clinical presentation, and procedural outcomes in a large patient population. Background Transradial access (TRA) has been associated with improved patient outcomes in selected populations in randomized trials. It is unclear whether these outcomes are achievable in clinical practice. Methods Using the BCIS (British Cardiovascular Intervention Society) database, we investigated outcomes for percutaneous coronary intervention procedures undertaken between 2007 and 2012 according to access site practice. Patients were categorized as stable, non-ST-segment elevation acute coronary syndrome (NSTEACS) and ST-elevation acute coronary syndrome (STEACS). The impact of access site on 30-day mortality, major adverse cardiac events, bleeding, and arterial access site complications was studied. Results Data from 210,260 TRA and 229,687 transfemoral access procedures were analyzed. Following multivariate analysis, TRA was independently associated with a reduction in bleeding in all presenting syndromes (stable odds ratio [OR]: 0.24, p < 0.001; NSTEACS OR: 0.35, p < 0.001; STEACS OR: 0.47, p < 0.001) as well as access site complications (stable OR: 0.21, p < 0.001; NSTEACS OR: 0.19; STEACS OR: 0.16, p < 0.001). TRA was associated with reduced major adverse cardiac events only in patients with unstable syndromes (stable OR: 1.08, p = 0.25; NSTEACS OR: 0.72, p < 0.001; STEACS OR: 0.70, p < 0.001). TRA was associated with improved outcomes compared with a transfemoral access (TFA) with a vascular closure device in a propensity matched cohort. Conclusions In this large study, TRA is associated with reduced percutaneous coronary intervention–related complications in all patient groups and may reduce major adverse cardiac events and mortality in ACS patients. TRA is superior to transfemoral access with closure devices. Use of TRA may lead to important patient benefits in routine practice. TRA should be considered the preferred access site for percutaneous coronary intervention. [ABSTRACT FROM AUTHOR]

Objectives This study sought to determine mortality rates among cardiogenic shock (CGS) patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome in the contemporary treatment era and to determine predictors of mortality. Background It is unclear whether recent advances in pharmacological and interventional strategies have resulted in further improvements in short- and long-term mortality and which factors are associated with adverse outcomes in patients presenting with CGS and undergoing PCI in the setting of acute coronary syndrome. Methods This study analyzed prospectively collected data for patients undergoing PCI in the setting of CGS as recorded in the BCIS (British Cardiovascular Intervention Society) PCI database. Results In England and Wales, 6,489 patients underwent PCI for acute coronary syndrome in the setting of CGS. The mortality rates at 30 days, 90 days, and 1 year were 37.3%, 40.0%, and 44.3%, respectively. On multiple logistic regression analysis, age (for each 10-year increment of age: odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.51 to 1.68; p < 0.0001), diabetes mellitus (OR: 1.47, 95% CI: 1.28 to 1.70; p < 0.0001), history of renal disease (OR: 2.03, 95% CI: 1.63 to 2.53; p < 0.0001), need for artificial mechanical ventilation (OR: 2.56, 95% CI: 2.23 to 2.94; p < 0.0001), intra-aortic balloon pump use (OR: 1.57, 95% CI: 1.40 to 1.76; p < 0.0001), and need for left main stem PCI (OR: 1.90, 95% CI: 1.62 to 2.23; p < 0.0001) were associated with higher mortality at 1 year. Conclusions In this large U.K. cohort of patients undergoing PCI in the context of CGS, mortality remains high in spite of the use of contemporary PCI strategies. The highest mortality occurs early, and this time period may be a particular target of therapeutic intervention. [ABSTRACT FROM AUTHOR]

Objectives This study sought to evaluate in-hospital outcomes and 3-year mortality of patients presenting with unprotected left main stem occlusion (ULMSO) treated with primary percutaneous coronary intervention (PPCI). Background Limited data exists about management and outcome following presentation with ULMSO. Methods From January 1, 2007 to December 21, 2012, 446,257 PCI cases were recorded in the British Cardiovascular Intervention Society database of all PCI cases in England and Wales. Of those, 568 were patients having emergency PCI for ST-segment elevation infarction (0.6% of all PPCI) who presented with ULMSO (TIMI [Thrombolysis In Myocardial Infarction] flow grade 0/1 and stenosis >75%), and they were compared with 1,045 emergency patients treated with nonocclusive LMS disease. Follow-up was obtained through linkage with the Office of National Statistics. Results Presentation with ULMSO, compared with nonocclusive LMS disease, was associated with a doubling in the likelihood of periprocedural shock (57.9% vs. 27.9%; p < 0.001) and/or intra-aortic balloon pump support (52.5% vs. 27.2%; p < 0.001). In-hospital (43.3% vs. 20.6%; p < 0.001), 1-year (52.8% vs. 32.4%; p < 0.001), and 3-year mortality (73.9% vs 52.3%, p < 0.001) rates were higher in patients with ULMSO, compared with patients presenting with a patent LMS, and were significantly influenced by the presence of cardiogenic shock. ULMSO and cardiogenic shock were independent predictors of 30-day (hazard ratio [HR]: 1.61 [95% confidence interval (CI): 1.07 to 2.41], p = 0.02, and HR: 5.43 [95% CI: 3.23 to 9.12], p<0.001, respectively) and 3-year all-cause mortality (HR: 1.52 [95% CI: 1.06 to 2.17], p = 0.02, and HR: 2.98 [95% CI: 1.99 to 4.49], p < 0.001, respectively). Conclusions In patients undergoing PPCI for ULMSO, acute outcomes are poor and additional therapies are required to improve outcome. However, long-term outcomes for survivors of ULMSO are encouraging. [ABSTRACT FROM AUTHOR]

Objectives: The purpose of this study was to compare baseline characteristics and medium-term prognosis in South Asian and Caucasian patients undergoing percutaneous coronary intervention (PCI). Background: It is unclear whether South Asians undergoing PCI have worse outcomes than Caucasians. Methods: We performed a retrospective analysis of 279,256 patients undergoing PCI from 2004 to 2011 from the British Cardiovascular Intervention Society national database, of whom 259,318 (92.9%) were Caucasian and 19,938 (7.1%) were South Asian (South Asian includes patients of Pakistani, Indian, Bangladeshi, or Sri Lankan ethnic origin). The main outcome measures were in-hospital major adverse cardiac and cerebrovascular events and all-cause mortality during a median follow-up of 2.8 years (interquartile range: 1.5 to 4.5 years). Results: South Asians were younger (59.69 ± 0.27 years vs. 64.69 ± 0.13 years, p > 0.0001); more burdened by cardiovascular risk factors, particularly diabetes mellitus (42.1 ± 1.2% vs. 15.4 ± 0.4%, p > 0.0001); and more likely to have multivessel coronary disease than Caucasians. In-hospital rates of major adverse cardiac and cerebrovascular events were similar for South Asians and Caucasians (3.5% vs. 2.8%, p = 0.40). Unadjusted Kaplan-Meier estimates of all-cause mortality showed better survival for South Asians compared with Caucasians, after PCI for either acute myocardial infarction or angina. Age-adjusted analysis revealed increased mortality (hazard ratio: 1.24; 95% confidence interval: 1.18 to 1.30), but after adjustment for the substantial variation in baseline risk factors including diabetes, there was no significant difference between South Asians and Caucasians (hazard ratio: 0.99; 95% confidence interval: 0.94 to 1.05). Conclusions: In this large, contemporary cohort of patients treated by PCI, South Asians were younger but had more extensive disease and major risk factors, particularly diabetes. However, after correcting for these differences, in-hospital and medium-term mortality of South Asians was no worse than that of Caucasians. This suggests that in South Asians, the high prevalence of diabetes exerts an adverse influence on mortality, but ethnicity itself is not an independent predictor of outcome.

Objectives: This study sought to investigate the influence of access site utilization on mortality, major adverse cardiac and cardiovascular events (MACCE), bleeding, and vascular complications in a large number of patients treated by primary percutaneous coronary intervention (PPCI) in the United Kingdom over a 5-year period, through analysis of the British Cardiovascular Intervention Society database. Background: Despite advances in antithrombotic and antiplatelet therapy, bleeding complications remain an important cause of morbidity and mortality in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing PPCI. A significant proportion of such bleeding complications are related to the access site, and adoption of radial access may reduce these complications. These benefits have not previously been studied in a large unselected national population of PPCI patients. Methods: Mortality (30-day), MACCE (a composite of 30-day mortality and in-hospital myocardial re-infarction, target vessel revascularization, and cerebrovascular events), and bleeding and access site complications were studied based on transfemoral access (TFA) and transradial access (TRA) site utilization in PPCI STEMI patients. The influence of access site selection was studied in 46,128 PPCI patients; TFA was used in 28,091 patients and TRA in 18,037. Data were adjusted for potential confounders using Cox regression that accounted for the propensity to undergo radial or femoral approach. Results: TRA was independently associated with a lower 30-day mortality (hazard ratio [HR]: 0.71, 95% confidence interval [CI]: 0.52 to 0.97; p < 0.05), in-hospital MACCE (HR: 0.73, 95% CI: 0.57 to 0.93; p < 0.05), major bleeding (HR: 0.37, 95% CI: 0.18 to 0.74; p < 0.01), and access site complications (HR: 0.38, 95% CI: 0.19 to 0.75; p < 0.01). Conclusions: This analysis of a large number of PPCI procedures demonstrates that utilization of TRA is independently associated with major reductions in mortality, MACCE, major bleeding, and vascular complication rates.

Background: Neurologic complications (NCs) are a rare but potentially devastating complication that may follow percutaneous coronary intervention (PCI). In recent years, there has been an increase in use of transradial access, driven by a developing body of evidence that favors its use over femoral access. Concerns have been raised, however, that transradial access may increase the risk of NC compared with transfemoral access. We aimed to investigate the influence of access site selection on the occurrence of NCs through a period of transition during which transradial access became the dominant route for PCI procedures performed in the United Kingdom. Methods: We performed a retrospective analysis of the British Cardiovascular Intervention Society database between January 2006 and December 2010. The data were split into 2 cohorts based on access site. An NC was defined as a periprocedural ischemic stroke, hemorrhagic stroke, or transient ischemic attack occurring before hospital discharge. Binary logistic multivariate analysis was used to investigate the influence of access site utilization on NCs and adjust for measured confounding factors. Results: Between 2006 and 2010, the use of radial access increased from 17.2% to 50.8% of all PCI procedures. A total of 124,616 radial procedures and 223,476 femoral procedures were studied with a NC rate of 0.11% in each cohort. In univariate (odds ratio 1.01, 95% CI 0.82-1.24, P = .93) and multivariate analysis (odds ratio 0.99, 95% CI 0.79-1.23, P = .91), there was no significant association between the use of radial access and the occurrence of NCs. Conclusion: These results suggest that radial access is not associated with an increased risk of clinically detected NCs, even during a period when there was a rapid evolution in the preferred access site for PCI in the United Kingdom. These are reassuring results, particularly for operators embarking on a change to radial access for PCI. [Copyright &y& Elsevier]

Background: Novel treatment strategies are required to reduce the development of acute kidney injury (AKI) in patients undergoing cardiac surgery. In this respect, remote ischemic preconditioning (RIPC), a phenomenon in which transient nonlethal ischemia applied to an organ or tissue protects another organ or tissue from subsequent lethal ischemic injury, is a potential renoprotective strategy. Study Design: Secondary analysis of 2 randomized trials. Setting & Participants: 78 consenting selected nondiabetic patients in a university teaching hospital undergoing elective coronary artery bypass graft (CABG) surgery recruited to 2 previously reported randomized studies. Intervention: RIPC consisted of three 5-minute cycles of right forearm ischemia, induced by inflating a blood pressure cuff on the upper arm to 200 mm Hg, with an intervening 5 minutes of reperfusion, during which time the cuff was deflated. The control consisted of placing an uninflated cuff on the arm for 30 minutes. Outcomes: AKI measured using Acute Kidney Injury Network (AKIN) criteria, duration of hospital stay, in-hospital and 30-day mortality. Results: Numbers of participants with AKI stages 1, 2, and 3 were t (3%), 3 (8%), and 0 in the intervention group compared with 10 (25%), 0, and 0 in the control group, respectively (P = 0.005). The decrease in AKI was independent of the effect of concomitant aortic valve replacement and cross-clamp times, which were distributed unevenly between the 2 groups. Limitations: Retrospective analysis of data. More patients in the RIPC group underwent concomitant aortic valve replacement with CABG; although we have corrected statistically for this imbalance, it remains an important confounding variable. Conclusions: RIPC induced using transient forearm ischemia decreased the incidence of AKI in nondiabetic patients undergoing elective CABG surgery in this retrospective analysis. A large prospective clinical trial is required to study this effect and clinical outcomes in patients undergoing cardiac surgery. [ABSTRACT FROM AUTHOR]

Summary: Accurate preoperative localisation of deep inferior epigastric artery perforator (DIEaP) provides optimal surgical planning for DIEaP flaps. Cross-sectional imaging by contrast-enhanced magnetic resonance angiography (CE-MRA) has advantages over previously described techniques for perforator imaging including reduced radiation exposure and better muscle to vessel contrast. A retrospective series of 10 unilateral free breast reconstructions following preoperative CE-MRA of the anterior abdominal wall is presented. Mean age of the patients at the time of surgery was 50.3 years (range 44–63 years). An average of 2.8 perforators per study (range 1–5) was identified. Mean perforator luminal diameter was 2.6mm (1.4–4.0mm) with a mean intramuscular course length of 22.3mm (6.4–51.9mm). Perforator course length was classified as 17% long intramuscular course (>4cm), 80% short intramuscular course (<4cm) and 3% paramedian. In all 10 patients, DIEaP flaps were successfully elevated. In all cases the flaps were elevated on vessels identified in preoperative review of the CE-MRA. There was a significant difference in the rates of conversion from DIEaP to transverse rectus abdominis myocutaneous (TRAM) flaps in the group who underwent CE-MRA in comparison to historical controls from the previous year (P =0.025). CE-MRA is an effective tool for DIEaP flap planning. [Copyright &y& Elsevier]

Summary: Background: Long-term follow-up of weight loss interventions is essential, but collecting weights can be difficult, and self-reports inaccurate. We examined the relationship between weight measures obtained in the context of a weight loss trial and in routine clinical care. Methods: Body weight data from a trial of behavioral obesity treatment among 88 obese women and 203 women age 40–65 years with comorbid obesity and depression were compared against weight data entered into an electronic medical record (EMR) during routine clinical care. Study and EMR weights and weight changes were then compared at 6 and 12 months using scatterplots, Pearson’s correlations, and t-tests. Results: The 12-month follow-up rate for this trial was 77%. Among the 224 12-month completers, 142 women (63%) had an EMR weight within 90 days of their 12-month study weight. Study and EMR weights were highly correlated (0.99), with a mean difference of 0.1kg. The correlation between two measures of 12-month weight change using study and EMR weights was 0.96. These results were robust to sensitivity analyses that explored the impact of different-sized windows for matching clinical weights with study weights. Among the 67 women who were missing study weights at 12 months, 33 (49%) had an EMR weight available within 90 days of their missed follow-up appointment. Conclusions: Weight measures routinely obtained in clinical care are highly correlated with those obtained by trained research staff and may be used, without statistical correction, to achieve higher rates of long-term follow-up in weight loss studies.

One hundred patients with contraindications to the femoral approach were randomized to undergo diagnostic coronary angiography via percutaneous radial puncture or brachial artery cutdown. Procedure duration, fluoroscopy time, and total radiation dose were significantly less via the radial route, whereas procedural success, complication rates, and pain scores were comparable; we conclude that the radial technique should be the arm approach of choice for new trainees, although there will be occasions when radial access fails and a brachial approach is required.

Background Gender is a strong predictor of periprocedural major bleeding complications after percutaneous coronary intervention (PCI). The access site represents an important site of such bleeding complications, which has driven adoption of the transradial access (TRA) use during PCI, although female gender is an independent predictor of transradial PCI failure. This study sought to define gender differences in access site practice and study associations between access site choice and clinical outcomes for PCI over a 6-year period, through the analysis of the British Cardiovascular Intervention Society observational database. Methods and Results In-hospital major adverse cardiovascular events (a composite of in-hospital mortality and in-hospital myocardial reinfarction and target vessel revascularization), in-hospital bleeding complications, and 30-day mortality were studied based on gender and access site choice (transfemoral access, TRA) in 412,122 patients who underwent PCI between 2007 and 2012 in the United Kingdom. Use of TRA increased in both genders over time, although this lagged behind in women (21% in 2007 to 58% in 2012) compared with men (24% in 2007 to 64% in 2012). In both men and women, TRA was independently associated with a lower in-hospital major adverse cardiovascular event (odds ratio [OR] 0.82, 95% CI 0.76-0.90; OR 0.75, 95% CI 0.66-0.84), in-hospital major bleeding (OR 0.54, 95% CI 0.44-0.66; OR 0.26, 95% CI 0.20-0.33), and 30-day mortality (OR 0.80, 95% CI 0.73-0.89; OR 0.82, 95% CI 0.71-0.94), respectively. Conclusions Where possible, TRA should be considered as the preferred access site choice for PCI, particularly in women in whom the greatest reductions bleeding end points were observed across all indications.

Background Erythropoiesis-stimulating agents (ESAs) have been investigated in small studies in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Erythropoiesis-stimulating agents did not show a clear effect on left ventricular function or clinical outcome, but some studies suggested an increased risk of thromboembolic events. Methods A systematic literature search in MEDLINE was performed, until December 2012. We included randomized clinical trials investigating the effect of ESAs in STEMI patients undergoing primary PCI, with ≥30 days of follow-up. The primary end point was a composite of all-cause mortality, myocardial infarction, and stent thrombosis after PCI. Secondary end point was all-cause mortality. Results Individual patient data were obtained from 10 of 11 trials, including 97.3% (1,242/1,277) of all patients randomized to control (n = 600) or to ESAs (n = 642). Baseline characteristics were well balanced between the treatment allocations. Mean follow-up time was 248 (±131) days. The primary end point occurred in 3.5% (20/577) in the control group and in 2.1% (13/610) in the ESA group (hazard ratio for ESAs, 0.63; 95% CI [0.31-1.27]; P = .20). Mortality occurred in 13 (2.3%) in the control group and 5 (0.8%) in the ESA group (hazard ratio for ESAs, 0.38; 95% CI [0.13-1.06]; P = .06). Conclusions Erythropoiesis-stimulating agent administration does not result in an increased risk of adverse cardiac events in STEMI patients undergoing primary PCI. Results of ongoing studies may provide further insight to the potential beneficial clinical effects of ESAs in STEMI patients. [ABSTRACT FROM AUTHOR]

Background: Cardiogenic shock (CS) remains the leading cause of mortality in patients hospitalized with acute myocardial infarction (AMI). The transradial access site (TRA) has become increasingly adopted as a default access site for percutaneous coronary intervention (PCI); however, even in experienced centers that favor the radial artery as the primary access site during PCI, patients presenting in CS are often treated via the transfemoral access site (TFA); and commentators have suggested that CS remains the final frontier that has given even experienced radial operators pause. We studied the use of TRA in patients presenting in CS in a nonselected high-risk cohort from the British Cardiovascular Intervention database over a 7-year period (2006-2012). Methods: Mortality (30-day) and major adverse cardiac and cerebrovascular events (a composite of in-hospital mortality, in-hospital myocardial reinfarction, target vessel revascularization, and cerebrovascular events) were studied based on TFA and TRA utilization in CS patients. The influence of access site selection was studied in 7,231 CS patients; TFA was used in 5,354 and TRA in 1,877 patients. Results: Transradial access site was independently associated with a lower 30-day mortality (hazard ratio [HR] 0.56, 95% CI 0.46-0.69, P = 0 < .001), in-hospital major adverse cardiac and cerebrovascular events (HR 0.64, 95% CI 0.53-0.76, P < .0001) and major bleeding (HR 0.37, 95% CI 0.18-0.73, P = .004). Conclusions: Although the majority of PCI cases performed in patients with cardiogenic shock in the United Kingdom are performed through the TFA, the radial artery represents an alternative viable access site in this high-risk cohort of patients in experienced centers.

Summary: Background: Obesity and depression are closely linked, and each has been associated with disability. However, few studies have assessed inter-relationships between these conditions. Design and methods: In this study, 4641 women aged 40–65 completed a structured telephone interview including self-reported height and weight, the Patient Health Questionnaire (PHQ) assessment of depression, and the World Health Organization Disability Assessment Schedule II (WHODAS II). The survey response rate was 62%. We used multivariable regression models to assess relationships between obesity, depression, and disability. Results: The mean age was 52 years; 82% were White; and 80% were currently employed. One percent were underweight, 39% normal weight, 27% overweight, and 34% obese. Mild depressive symptoms were present in 23% and moderate-to-severe symptoms were present in 13%. After multivariable adjustment, depression was a strong independent predictor of worse disability in all 7 domains (cognition, mobility, self-care, social interaction, role functioning, household, and work), but obesity was only a significant predictor of greater mobility, role-functioning, household, and work limitations (P <0.05) (overweight was not significantly associated with any disability domain). Overall, the effect on disability was stronger and more pervasive for depression than obesity, and there was no significant interaction between the two conditions (P >0.05). Overweight and obesity were associated with 5760 days of absenteeism per 1000 person-years, and depression was associated with 18,240 days of absenteeism per 1000 person-years. Conclusions: The strong relationships between depression, obesity and disability suggest that these conditions should be routinely screened and treated among middle-aged women.

Summary: Data from a trial of a 26-session structured group behavioral weight loss intervention were used to examine how group attendance, weight loss, and changes in depression clustered within therapy groups. Participants were recruited via a population-based survey of female health plan members aged 40–65. The sample included 143 women attending 13 therapy groups. Average number of sessions attended was 15.9 (S.D. 7.2) and average weight loss over 12 months was 4.24kg (S.D. 7.79kg). In hierarchical (random effects) linear models predicting attendance and weight loss, attendance did cluster significantly within therapy groups (F =2.83, df=12, p =.002; ICC=.14) but weight loss (F =0.89, df=12, p =.56; ICC=.00) and change in depressive symptoms (F =0.25, df=12, p =.99; ICC=.00) did not. Accounting for baseline characteristics of group participants had no significant effect on these findings. Relatively small average weight loss in this sample may have limited our ability to detect clustering of weight loss within groups. We conclude that clinicians should consider addressing the effects of drop-out on other group members and that researchers should consider the impact of clustering in analyses of data regarding group treatments.

Background Poor quality cardiopulmonary resuscitation (CPR) predicts adverse outcome. During invasive cardiac procedures automated-CPR (A-CPR) may help maintain effective resuscitation. The use of A-CPR following in-hospital cardiac arrest (IHCA) remains poorly described. Aims & methods Firstly, we aimed to assess the efficiency of healthcare staff using A-CPR in a cardiac arrest scenario at baseline, following re-training and over time (Scenario-based training). Secondly, we studied our clinical experience of A-CPR at our institution over a 2-year period, with particular emphasis on the details of invasive cardiac procedures performed, problems encountered, resuscitation rates and in-hospital outcome (AutoPulse-CPR Registry). Results Scenario-based training: Forty healthcare professionals were assessed. At baseline, time-to-position device was slow (mean 59 (± 24) s (range 15-96 s)), with the majority (57%) unable to mode-switch. Following re-training time-to-position reduced (28 (± 9) s, p < 0.01 vs baseline) with 95% able to mode-switch. This improvement was maintained over time. AutoPulse-CPR Registry: 285 patients suffered IHCA, 25 received A-CPR. Survival to hospital discharge following conventional CPR was 28/260 (11%) and 7/25 (28%) following A-CPR. A-CPR supported invasive procedures in 9 patients, 2 of whom had A-CPR dependant circulation during transfer to the catheter lab. Conclusion A-CPR may provide excellent haemodynamic support and facilitate simultaneous invasive cardiac procedures. A significant learning curve exists when integrating A-CPR into clinical practice. Further studies are required to better define the role and effectiveness of A-CPR following IHCA. [ABSTRACT FROM AUTHOR]
