Several rare mutations associated with familial lone atrial fibrillation (AF) have been identified; however, the phenotypes are varied and poorly elucidated.Here, we report a 29-year-old woman with AF refractory to anti-arrhythmic drugs. Her family history revealed early-onset and persistent AF in her father and brother as well. Genetic analysis subsequently demonstrated a c.421G>A mutation in the KCNQ1 gene. Unique phenotypes including absence of both atrial appendages, extremely high atrial frequencies, and refractoriness to both ablative and pharmacological therapy were observed. Our study suggests the need for further exploration of the function of KCNQ1 and the mechanism of AF.

Background and aimsLeft ventricular hypertrophy (LVH) is prevalent in obese individuals. Besides, both of LVH and obesity is associated with subclinical LV dysfunction. However, little is known about the interplay between body fat and LVH in relation to all-cause death in patients with coronary artery disease (CAD).MethodsIn this retrospective cohort study, a total of 2243 patients with angiographically proven CAD were included. Body fat and LV mass were calculated using formulas. Higher body fat was defined as the percentage of body fat was greater than 75th percentile. LVH was defined according to guidelines’ definition. Patients were divided into four groups: group 1, lower body fat and no LVH; group 2, lower body fat and LVH; group 3, higher body fat and no LVH; group 4, higher body fat and LVH. Cox-proportional hazard models were used to observe the interaction effect of body fat and LVH on all-cause death.ResultsOver 2.2 years, there were 120 deaths. Patients with higher body fat and no LVH (group 3) had similar risk of death (adjusted HR 1.83, 95%CI 1.00-3.38, P = 0.054) compared to the reference group (group 1), while patients with lower body fat and LVH (group 2) had the highest risk (adjusted HR 2.15, 95%CI 1.26–3.64, P = 0.005) of death. The results were robust after different degree of adjustment.ConclusionCertain amount of BF was not associated with increased risk of all-cause death in patients with CAD, even seems protective in those concomitant with LVH.

Background Contemporary heart failure medications have led to considerable improvement in the survival of patients with heart failure. However, limited evidence is available regarding the effect of those medications in patients with idiopathic dilated cardiomyopathy (IDCM), particularly in China. We sought to analyze the trends in clinical characteristics and the prescription rate of recommended therapies and its prognostic impact in patients with IDCM. Methods From 2009 to 2016, 1441 consecutive patients (age: 55±14 years, 68% men, LVEF: 33% ± 12%) fulfilling World Health Organization criteria for IDCM were enrolled in the current retrospective cohort study. Temporal trends of baseline clinical characteristics, treatment and prognosis were analyzed, and potential influential factors were explored. Results Rates of patients receiving angiotensin-converting enzyme inhibitors/angiotensin II receptors blockers, β-blockers, aldosterone receptor antagonists and diuretics increased from 55%, 45%, 58%, 51% in 2009 to 67%, 69%, 71%, 64% in 2016, respectively (P < 0.05); whereas, the proportion of patients receiving digoxin decreased from 39% in 2009 to 28% in 2016 (P < 0.05). The overall proportion of patients with optimal guideline-directed medical therapy (GDMT) was 44.6%; however, that rate increased from 33% in 2009 to 41%, 49% and 56% in 2012, 2014 and 2016 respectively (P < 0.05). Patients with optimal GDMT had a better outcome than those without, but there was no temporal trend toward improvement in the overall long-term prognosis of IDCM patients with the years. There was a trend towards admission of patients with milder disease and toward increased admission to a cardiology ward with the years. Conclusions An improvement in prescription rates of guideline-recommended medications in IDCM patients was observed. However, it remains suboptimal, and there is still some room for improvement. The prognosis of patients with optimal GDMT was better than those without. Moreover, the following patient category also had an improved prognosis: patients with LVEF ≥ 40%, with device therapy, and those admitted to a cardiology ward.

Few data are available regarding the prevalence and clinical significance of right ventricular systolic dysfunction (RVSD) in hypertrophic cardiomyopathy (HC) patients. This study aimed to evaluate right ventricular (RV) systolic function by cardiovascular magnetic resonance and explore the prevalence and prognostic significance of RVSD in HC patients. A total of 226 patients with HC assessed by cardiovascular magnetic resonance were included in this retrospective study. RVSD was defined by RV ejection fraction (RVEF) ≤45% and was present in 26 (11.5%) patients. Association between RVSD, clinical characteristics, and outcomes were analyzed. RVEF was significantly lower in patients with RVSD than without RVSD (36.2 ± 7.0% vs 60.5 ± 7.4%, p0.001). There was a positive correlation between RVEF and left ventricular ejection fraction (r = 0.45; p0.001). During a mean follow-up of 30.5 ± 23.9 months, there were 22 (9.7 %) all-cause mortality, including 12 (5.3%) cardiovascular death. Kaplan-Meier analysis showed a significantly higher risk for cardiovascular mortality in patients with RVSD (p = 0.026), but no significant difference in all-cause mortality (p = 0.118) and heart failure related rehospitalization (p = 0.485). On multivariate Cox regression analysis, RVSD (hazard ratio 5.36; confidence interval 1.39 to 20.77; p = 0.015) and RVEF (hazard ratio 0.94; confidence interval 0.89 to 0.98; p = 0.011) were independent predictors of cardiovascular mortality. In conclusion, RVSD is a common phenotype and a strong independent predictor of cardiovascular mortality in HC patients.

Background: The impact of renal function on the prognostic value of N-terminal pro–B-type natriuretic peptide (NT-proBNP) remains unclear in coronary artery disease (CAD). This study sought to investigate the value of using NT-proBNP level to predict prognoses of CAD patients with different estimated glomerular filtration rates (eGFRs). Methods: A retrospective analysis was conducted from a single registered database. 2087 consecutive patients with CAD confirmed by coronary angiography were enrolled. The primary endpoint was allcause mortality. Results: The mean follow-up time was 26.4 ± 11.9 months and death events occurred in 197 cases. The NT-proBNP levels increased with the deterioration of renal function, as well as the optimal cutoff values based on eGFR stratification to predict endpoint outcome (179.4 pg/mL, 1443.0 pg/mL, 3478.0 pg/mL, for eGFR ≥ 90, 60–90 and < 60 mL/min/1.73 m2, respectively). Compared with the routine cut-off value or overall optimal one, stratified optimal ones had superior predictive ability for endpoint in each eGFR group (all with the highest Youden’s J statistics). And the prognostic value became weaker as eGFR level decreased (eGFR ≥ 90 vs. 60–90 vs. < 60 mL/min/1.73 m2, odds ratio [OR] 7.7; 95% confidence interval [CI] 1.7–33.9 vs. OR 4.8; 95% CI 2.7–8.5 vs. OR 3.0; 95% CI 1.5–6.2). Conclusions: This study demonstrated that NT-proBNP exhibits different predictive values for prognosis for CAD patients with different levels of renal function. Among the assessed values, the NT-proBNP cut-off value determined using renal function improve the accuracy of the prognosis prediction of CAD. Moreover, lower eGFR is associated with a higher NT-proBNP cut-off value for prognostic prediction.

Statins therapy in the secondary prevention of coronary artery disease (CAD) is associated with a lower risk of adverse cardiovascular events. However, little is known regarding the association of elderly patients with nutritional risk on statin therapy. To investigate whether older patients with CAD who were at nutritional risk gain similar survival benefit from statins therapy as their counterparts without nutritional risk. We conducted a retrospective hospital-based cohort study among 1705 patients with CAD who were older than 65 years of age, using coronary heart disease database from 2008 to 2012. Nutritional status of included patients was gauged using the geriatric nutritional risk index. After stratification by nutritional status, the hazard of all-cause death was compared between those with or without statins therapy. Of the 1705 patients included in the study (mean age 72 years; 73% male), all-cause death occurred in 146 (9.2%) patients with statins use and in 33 (26.2%) patients without statins use. The rate of all-cause death was higher in patients not receiving statins irrespective of nutritional status. After adjustments for potential confounders, the HR with statins use was 0.33 (95% CI 0.20–0.55) in patients without nutritional risk and 0.47 (95% CI 0.22–1.00) in patients with nutritional risk. No interaction effect was detected between nutritional status and statins use in relation to all-cause death (P value for interaction effect 0.516). Despite of the patient’s nutritional status, statins therapy as a secondary prevention in elderly CAD patients was associated with decreased risk of all-cause death.

Tremendous effort has been invested in reducing the prevalence of atherosclerotic cardiovascular disease (ASCVD) in China. Meanwhile, accumulating evidence has emerged to show the benefits of statins in the prevention of cardiovascular disease. The present study investigated the change trends of statins prescription at discharge among patients with ASCVD in recent years, differences across subtypes of ASCVD, and associated factors. The study included 51,972 patients with a discharge diagnosis of ASCVD who were hospitalized in West China Hospital from 2008 to 2014. Trends of statins prescription rates between subtypes of ASCVD were compared and potential influential factors were explored. The overall statins prescription rate in patients with ASCVD was 58.8%. Adjusted odds ratios (ORs) of increase in prescription rate per year were 1.15 (95% CI 1.13-1.17, p

Few studies to date address the predictive ability of CHA2DS2-VASc and R2CHADS2 in CAD patients. Our aim is to investigate the prognostic performance of CHADS2, CHA2DS2-VASc and R2CHADS2 scores in patients with coronary artery disease (CAD). Angiographically obstructive CAD patients were enrolled. The prognostic performance of the three risk scores was evaluated using Cox hazards models. In addition, we compared their predictive values by calculating C statistics, net reclassification improvement (NRI) and integrated discrimination improvement (IDI). The endpoints are death from any cause and cardiovascular death. Of 3295 subjects with CAD, the mean CHADS2, CHA2DS2-VASc and R2CHADS2 scores are 1.2 ± 1.0, 2.4 ± 1.4, and 1.6 ± 1.4, respectively. The CHADS2-guided risk classification is markedly distinct from CHA2DS-2-VASc- and R2CHADS2-guided ones. Over a median follow-up of 24 months, a total of 290 (rate 4.00/100 person-year) deaths occurred, and 163 (rate 2.2/100 person-year) were attributed to cardiovascular deaths. Event rates increase by CHADS2, CHA2DS2-VASc and R2CHADS2 (P for trend

Fibrinogen (Fib) is considered to be a potential risk factor for the prognosis of patients with acute coronary syndrome (ACS), but it is unclear whether Fib level have synergistic effects to enhance the prognostic value of the GRACE score in patients with ACS. A retrospective analysis was conducted from a single registered database. 2253 consecutive patients with ACS confirmed by coronary angiography were enrolled and were grouped into 3 categories by the tertiles of admission plasma Fib levels. The end points were all-cause mortality and cardiac mortality. The mean follow-up time was 27.2 ± 13.1 months and death events occurred in 223 cases and cardiac death events occurred in 130 cases. Cumulative survival curves indicated that the risk of all-cause death increased with increasing Fib level (mortality rates for Tertile 1 vs. Tertile 2 vs. Tertile 3 = 6.6% vs. 10.8 %vs. 12.3%, p < 0.001). Cox multivariate regression analysis indicated that compared with other traditional risk factors, plasma Fib level is independently correlated with all-cause death (HR 1.33, 95% CI 1.04-1.70). However, incorporating elevated Fib level into the GRACE model did not significantly increase the predictive value of the GRACE score; for instance, AUC only increased from 0.703 to 0.713 (p = 0.765). In conclusion, Fib level at admission was independently associated with death risk among Chinese patients with ACS. However, the incorporation of Fib level at admission into the GRACE score did not improve this score's predictive value for death risk among these patients.

There is a controversy surrounding the correlation between fibrinogen (Fib) level and prognosis of coronary artery disease (CAD). We try to investigate the role of the subtypes of CAD in this controversy.A retrospective analysis was conducted from a single center CAD registered database. 3020 consecutive patients with CAD confirmed by coronary angiography were enrolled. The end points were all-cause mortality.The mean follow-up time was 27.2±13.1months and death events occurred in 258 cases. Mortality rates for patients with CAD and those in the stable coronary artery disease (SCAD) and unstable angina pectoris (UAP) groups exhibited an overall rising trend as Fib levels increased (log rank test, all p0.05). However, similar trends were not detected in patients with acute myocardial infarction (AMI). The results of a Cox proportional-hazards regression analysis showed that Fib level was independently correlated with the risk of death in patients with CAD as well as those in the SCAD and UAP groups (CAD, HR 1.40, CI 1.16-1.68; SCAD, HR 1.86, CI 1.24-2.79; UAP, HR 1.42, CI 1.06-1.90). In the AMI group, however, no independent correlation was observed between Fib level and mortality.The different proportions of subtypes of CAD affected the correlation between Fib level and the clinical prognosis of patients with CAD. This is maybe a clue to explain the controversy.

Gender plays a crucial role in the prevalence, clinical presentation, management and outcomes of various cardiovascular diseases. The aim of this study was to evaluate the impact of gender on clinical manifestations and outcomes in the Chinese patients with hypertrophic cardiomyopathy (HCM).We evaluated 576 Chinese patients (316 males) who were diagnosed with HCM at West China Hospital from 2008 to 2016 and followed over 3.2 ± 2.3 years.Compared to male patients, female patients were older (57.2 ± 16.7 years vs. 53.0 ± 15.7 years, P = 0.002) and more symptomatic [New York Heart Association class III-IV symptoms 46.9% vs. 30.7%, P0.001] at the time of diagnosis, and had higher left ventricular outflow tract gradient at rest [33 (12-58) mmHg vs. 24 (8-42) mmHg, P = 0.007]. During the follow-up period, survival analysis showed no significant differences in the incidences of all-cause mortality (P = 0.657) and cardiovascular mortality (P = 0.214) but the rate of rehospitalization due to heart failure was higher in females than in males (P = 0.015). Multivariable Cox analysis showed that left ventricular ejection fraction (hazard ratio [HR], 0.96 [95% confidence interval [CI], 0.94-0.99]; P = 0.003) and New York Heart Association class III-IV (HR, 2.86 [95% CI, 1.38-5.94]; P = 0.005) were independently associated with cardiovascular mortality.Compared to males, females were older and more symptomatic at presentation, and had higher risk of progression to heart failure in Chinese HCM patients but there were no differences in cardiovascular mortality.

Currently, there are no studies addressing the influence of age on the prognostic information of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in Asian population with acute coronary syndrome (ACS). The purpose of this study was to investigate the prognostic performance of NT-proBNP in Chinese patients with ACS across different age groups. A total of 1512 ACS patients with venous blood NT-proBNP measured were enrolled. Patients were divided into tertiles based on their ages (

We present a case of aortic coarctation combined with ascending-descending aorta dilatation and concomitant aortic valve regurgitation. The technique involved using endovascular stenting, a two-stage balloon dilation procedure post-stent implantation and a Bentall procedure.

Background Ageing is a risk factor for both coronary artery disease (CAD) and reduced renal function (RRF), and it is also associated with poor prognosis in patients with CAD or RRF. However, little is known about whether the impact of RRF on clinical outcomes are different in CAD patients at different age groups. This study aimed to investigate whether ageing influences the effect of RRF on long-term risk of death in patients with CAD. Methods A retrospective analysis was conducted using data from a single-center cohort study. Three thousand and two consecutive patients with CAD confirmed by coronary angiography were enrolled. RRF was defined as an estimated glomerular filtration rate (eGFR) of less than 60 ml/min. The primary endpoint in this study was all-cause mortality. Results The mean follow-up time was 29.1 ± 12.5 months and death events occurred in 275 cases (all-cause mortality: 9.2%). The correlation analysis revealed a negative correlation between eGFR and age (r = − 0.386, P

Background Elderly patients with coronary artery disease (CAD) frequently complicated with more cardiovascular risk factors, but received fewer evidence-based medications (EBMs). This study explored the association of EBMs compliance in different age groups and the risk of long-term death. Methods A retrospective analysis was conducted from a single registered database. 2830 consecutive patients with CAD were enrolled and grouped into 3 categories by age. The primary end point was all-cause mortality and secondary endpoint is cardiovascular mortality. Results The mean follow-up time was 30.25 ± 11.89 months and death occurred in 270 cases,including 150 cases of cardiac death. Cumulative survival curves indicated that the incidence rates of all-cause death and cardiovascular death increased with age (older than 75 years old vs. 60 to 75 years old vs. younger than 60 years old, mortality: 18.7% vs. 9.6% vs. 4.1%, p

Frequent premature atrial complexes (PACs) are universal in the general population; however, their clinical significance is unclear. We hypothesize that frequent PACs are associated with increased risk of stroke and death. The PubMed (from 1966 to April 2017) and Embase (from 1974 to April 2017) databases were searched for longitudinal studies that reported the relation of PACs with incidence of stroke and death with various etiologies. Study quality was evaluated, and the relative risks (RR) of unfavorable outcomes in subjects with frequent PACs vs those without were calculated. Eleven studies with overall high quality were eligible according to inclusion criteria. The meta-analysis demonstrated that frequent PACs were associated with an increased risk of stroke (unadjusted RR: 2.20, 95% confidence interval [CI]: 1.79-2.70; adjusted RR: 1.41, 95% CI: 1.25-1.60) and death from all causes (unadjusted RR: 2.17, 95% CI: 1.80-2.63; adjusted RR: 1.26, 95% CI: 1.13-1.41), cardiovascular diseases (unadjusted RR: 2.89, 95% CI: 2.20-3.79; adjusted RR: 1.38, 95% CI: 1.24-1.54), and coronary artery disease (unadjusted RR: 2.74, 95% CI: 1.64-4.58; adjusted RR: 1.74, 95% CI: 1.27-2.37). No significant publication bias was detected. The association was robust in sensitivity analysis, subgroup analysis, and pooled analysis of estimates adjusting for confounding factors. Frequent PACs are not benign phenomena; they are associated with higher risk of unfavorable outcomes. Further research on the optimal management of subjects with frequent PACs is urgently required.

Objective To analyze the current usage of optimal medical therapy (OMT), influencing factors, and the predictive value of OMT for all-cause mortality in coronary artery disease (CAD) patients with different subgroups. Methods A total of 3176 CAD patients confirmed by coronary angiography were included. OMT was defined as the combination of anti-platelet drugs, statins, beta blockers, and angiotensin converting enzyme inhibitors or angiotensin receptor blockers. Factors for OMT and its prognostic value were analyzed in CAD patients across different subgroups. Results Out of 3176 patients, only 39.8% (n = 1265) were on OMT at discharge. Factors associated with OMT at discharge were pre-admission OMT and discharge department. All-cause mortality occurred in 6.8% (n = 217) of patients. Multivariate analyses indicated that OMT was significantly associated with reduced all-cause mortality (HR: 0.65, 95% CI: 0.45–0.95; P = 0.025). Sub-group analyses indicate that male acute coronary syndrome (ACS) patients were more likely to receive survival benefits with OMT at discharge. The positive impact of OMT at discharge was more apparent after 24 months, regardless of revascularization therapy. Four-drug combination of OMT was superior to 3-drug combination therapy in ACS patients but not in stable patients. Conclusions OMT was associated with significant improvement in survival in patients with CAD. The positive impact of OMT was distinct in the CAD patients with different characteristics.

OBJECTIVES Our aim was to investigate whether the presence of metabolic syndrome (MetS) and diabetes mellitus (DM) influenced the N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and its prognostic performance in coronary artery disease (CAD). PATIENTS AND METHODS The present study enrolled a total of 1638 CAD patients. Multivariate regression analyses were carried out to relate NT-proBNP to metabolic components, nondiabetic MetS, DM, and MetS score. Furthermore, we examined the prognostic performance of NT-proBNP in patients with non-MetS, nondiabetic MetS, and DM. RESULTS NT-proBNP levels correlated inversely with BMI (β=-0.11, P=0.003) and correlated positively with fasting glucose (β=0.12, P=0.001). There were no significant relationships of NT-proBNP with other metabolic parameters. Compared with non-MetS, the presence of DM significantly increased NT-proBNP levels (P=0.004), whereas nondiabetic MetS did not influence NT-proBNP levels (P=0.954). During the median follow-up of 21 months, 109 all-cause deaths occurred. NT-proBNP levels independently predicted all-cause deaths irrespective of the presence of nondiabetic MetS and DM (Pinteraction=0.43). CONCLUSION DM, but not nondiabetic MetS, is associated with higher NT-proBNP levels. NT-proBNP can still predict death in patients with CAD, even with the confounding effect of MetS and diabetes.

Few studies to date address the predictive ability of CHA

Background Whether body composition is associated with the N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and its prognostic performance in acute coronary syndrome (ACS) remains unknown. We aimed to investigate the influence of body composition on the NT-proBNP level and its prognostic performance among ACS patients. Methods In total, 1623 ACS patients with NT-proBNP data were enrolled. Percent body fat and lean mass index were estimated using the Clínica Universidad de Navarra—Body Adiposity Estimator equation. Patients were divided into three groups according to the tertiles of sex-specific body mass index, percent body fat, or lean mass index. The endpoints were death from any cause and cardiovascular death. Results Body mass index was inversely correlated with NT-proBNP levels (β = −0.036, P = 0.003). Lean mass index, but not percent body fat, was inversely associated with NT-proBNP levels (β of lean mass index = −0.692, P = 0.002). During a median follow-up of 23 months, 161 all-cause deaths occurred, and of these, 93 (57.8 %) were attributed to cardiovascular causes. Multivariate Cox analysis showed that the NT-proBNP level independently predicted all-cause mortality or cardiovascular death in the lower body mass index, lean mass index, and percent body fat groups. However, the prognostic performance of NT-proBNP was attenuated in patients with high body mass index, lean mass index, and percent body fat. In the subgroup of patients with diabetes, inverse associations between NT-proBNP levels and body mass index or body composition were not observed. In addition, the negative influence of high body mass index and body composition on the prognostic performance of the NT-proBNP level appeared to be attenuated. Conclusions Body mass index and lean mass index, but not percent body fat, are inversely associated with NT-proBNP levels. The prognostic performance of this biomarker may be compromised in patients with high body mass index, percent body fat, or lean mass index. Additionally, the influence of body composition on the NT-proBNP level and its prognostic performance might be attenuated in diabetic patients with ACS.

Our aim was to illustrate the effect of higher activated clotting time (ACT) values versus lower ACT values on thrombotic or hemorrhagic events in coronary atherosclerotic heart disease (CHD) patients undergoing percutaneous coronary intervention (PCI). PubMed, Embase, Web of Science, and Cochrane Library were searched. Observational studies assessing ACT related major adverse cardiac event (MACE) and major bleeding were included. Studies were allocated into three groups. Group 1 included studies with low percentage of participants prescribed with glycoprotein IIb/IIIa inhibitors ([GPI] ≤30%), Group 2 with high percentage of participants prescribed with GPI (>30%), and Group 3 with routine direct thrombin inhibitors (DTI) prescription. The cutoff is designed as 300s (290-310s) for Group 1, and 250s (240-260s) for Group 2. With regard to MACE and major bleeding in Group 1, there was no significant difference between higher ACT values and lower ACT values (risk ratio [RR] for MACE, 1.16, 95% confidence interval [CI], 0.65-2.05, p=0.62, I(2)=94%, RR for major bleeding, 0.96, 95% CI, 0.66-1.40, p=0.83, I(2)=0%). Likewise, no significant difference was found in Group 2 between higher ACT values and lower ACT values (RR for MACE, 1.15, 95% CI, 0.97-1.35, p=0.10, I(2)=0%, RR for major bleeding, 0.85, 95% CI, 0.45-1.60, p=0.61, I(2)=83%). In conclusion, ACT may not have a substantial effect on thrombotic or hemorrhagic complications. Under current clinical practice, target ACT may be higher than what is necessary to prevent thrombotic events. We may achieve a relative low ACT level to preserve efficacy and enhance safety.

Background TAVR is a rapidly spreading treatment option for severe aortic valve stenosis. Significant coronary artery disease (CAD) is present in 40% to 75% of patients undergoing TAVR. However, when to treat the concomitant coronary artery lesions is controversial. Methods This is a systematic review comparing concomitant PCI and TAVR versus staged PCI and TAVR. The OVID database was systematically searched for studies reporting PCI in patients undergoing TAVR. A random effects model was used to calculate the pooled odds ratio (OR) with 95% confidence intervals. Results Four observational studies and a total of 209 patients were included in this analysis. Overall 30-day mortality was similar between concomitant PCI and TAVR versus staged PCI and TAVR [OR: 1.47 (0.47-4.62); P = .51], renal failure was not significantly different between both groups [OR: 3.22 (0.61-17.12); P = .17], periprocedural myocardial infarction was not different between the 2 groups [OR: 1.44 (0.12-16.94); P = .77], life-threatening bleeding did not differ between both groups [OR: 0.45 (0.11-1.87); P = .27], and major stroke also was not significantly different [OR: 3.41 (0.16-74.2); P = .44]. Conclusion These data did not show a significant difference in short-term outcomes between concomitant PCI and TAVR versus staged PCI and TAVR.

Rationale: Coarctation of aorta in adulthood is usually complicated by other cardiovascular anomalies, posing great technical challenge for intervention. Patient concerns: Here, we report an extremely rare case of aortic arch coarctation combined with a poststenotic biloculated calcified aneurysm and hypoplastic left subclavian artery. Interventions: First, an extra-anatomic bypass was established, along with narrowing of aorta just proximal and distal to the aneurysm. While the bypass graft significantly relieved trans-coarctation gradient, the latter procedure decreased intra-aneurysm pressure and created landing zones for aneurysm occlusion. Six months later, 2 muscular ventricular septal defect occluders were deployed at the proximal and distal orifice of the aneurysm. Outcomes: Follow-up computed tomography angiography confirmed the absence of contrast leakage into aneurysm. Conclusions: A 2-stage hybrid approach described here appears to be feasible, safe, and associated with favorable clinical outcomes in the treatment of complicated aortic coarctation and poststenotic aneurysm.

Bisphosphonates have shown potential to inhibit atherosclerosis in animal experiments; however, whether bisphosphonates therapy lowers the risk of incidence of myocardial infarction (MI) is debated. We performed the meta-analysis and trial sequential analysis (TSA) to investigate the relation between bisphosphonates therapy and incident MI.Pubmed and Embase databases were systematically searched in April 2015 to identify studies, which compared the incidence of MI in subjects receiving bisphosphonates with that in subjects not receiving the agents. Meta-analysis was conducted using random effects model in consideration of statistical heterogeneity between studies. Reliability of the results from meta-analysis was examined using TSA.Six observational studies (n = 440261) and 3 randomized control trials (RCTs, n = 11,024) met the eligible criteria. In the pooled analysis of observational studies, bisphosphonates therapy was not associated with reduced risk of MI either using unadjusted estimates (relative risk 0.93, 95% confidence interval (CI), 0.75-1.15) or estimates adjusted for confounding factors (hazard ratio 1.01, 95% CI, 0.84-1.21). Furthermore, hazard of incident MI did not differ between alendronate users and nonusers. TSA showed that evidence from observational studies firmly precluded the association between bisphosphonates and incident MI. Pooled analysis of RCTs also suggested no benefits of decrease in incident MI associated with bisphosphonates therapy (relative risk 1.05, 95% CI, 0.53-2.09). However, TSA demonstrated that evidence from RCTs was insufficient to draw a conclusion.Despite the encouraging findings from animal studies, bisphosphonates therapy is not associated with reduced risk of MI.

The aim of the present review was to investigate the association between the use of oral β-blockers and prognosis in patients with acute myocardial infarction (AMI) who underwent percutaneous coronary intervention (PCI) treatment. A systematic literature search was conducted in Pubmed (from inception to September 27, 2014) and Embase (Ovid SP, from 1974 to September 29, 2014) to identify studies that compared the outcome of patients with AMI taking oral β-blockers with that of patients not taking after PCI. Systematic review and meta-analysis were performed with random-effects model or fixed-effects model. Ten observational studies with a total of 40,873 patients were included. Use of β-blockers was associated with a reduced risk of all-cause death (unadjusted relative risk 0.58, 95% confidential interval 0.48 to 0.71; adjusted hazard ratio 0.76, 95% confidential interval 0.62 to 0.94). The potential benefit of β-blockers in preventing all-cause death was not similar in all population but was restricted to those with reduced ejection fraction, with low use proportion of other secondary prevention drugs or with non–ST-segment elevation myocardial infarction. The association between the use of β-blockers and improved survival rate was significant in ≤1-year follow-up duration. Rates of cardiac death, myocardial infarction, and heart failure readmission in patients using β-blockers were not significantly different from those in patients without β-blocker therapy. In conclusion, there is lack of evidence to support routine use of β-blockers in all patients with AMI who underwent PCI. Further trials are urgently needed to address the issue.

The purpose of this study was to discuss the present situation of discharge medications in coronary artery disease (CAD) patients with different levels of renal function and assess the potential impact of these medications on the prognosis of this patient population. A retrospective cohort study was conducted. From July 2008 to Jan 2012, consecutive patients with CAD confirmed by coronary angiography of West China Hospital were enrolled and were grouped into 3 estimated glomerular filtration rate (eGFR) categories: ≥60, 30 to 60, and
