The aim of this study was to quantify the relation between classical risk factors (smoking, diabetes, BMI, waist circumference, blood pressure, and lipids), risk factor targets, and risk of recurrent major atherosclerotic cardiovascular events (MACE). This was first done for recurrent MACE ≤65 years in patients aged <60 years and second for recurrent MACE ≤2.5 years after a first cardiovascular event. Data were used from the Second Manifestations of Arterial Disease study (n = 5,115), a prospective cohort of patients with a recent (≤1 year) first cardiovascular event...

Impaired left atrial emptying fraction (LAEF) is an important predictor of mortality in patients with heart failure. As it may reflect increased LV wall stress, it might predict ventricular arrhythmia (VA) specifically. This study evaluated the predictive value of LAEF assessed with cardiovascular magnetic resonance (CMR) imaging with respect to appropriate device therapy (ADT) for VA and compared its role with CMR assessed scar size and other risk factors. In total, 229 patients (68% male, 63 ± 10 years, 61% ischemic cardiomyopathy) with LV ejection fraction ≤35% who underwent CMR and implantable cardioverter defibrillator (ICD) implantation for primary prevention in 2005 to 2012 were included...

Implantable cardioverter defibrillators (ICDs) reduce the risk of sudden cardiac death in patients with impaired left ventricular ejection fraction (LVEF). However, there are limited data on the long-term benefit of ICD therapy in patients whose LVEF subsequently improves. We conducted a meta-analysis to evaluate the effect of LVEF improvement on ICD therapy during follow-up. Incidence rate ratios (IRRs) with 95% confidence intervals (CIs) were calculated using random-effects modeling. Sixteen studies with 3,959 patients were included in our analysis...

The results of the Placement of AoRtic TraNscathetER Valves (PARTNER) 2 trial established the feasibility of transcatheter aortic valve replacement (TAVR) for intermediate surgical risk patients. The expansion of TAVR into the low-risk patient population will largely depend on its durability outcomes due to the high life expectancy in low-risk patients. Long-term follow-up results from low-risk clinical trials will take several years to be reported. Given this, we performed a systematic review of current long-term data to provide further insights into TAVR durability and long-term patient survival...

Co-morbidities increase markedly with aging, and they often negatively affect its prognosis. Although mortality with transcatheter mitral valve repair (TMVr) is significantly less than for open mitral valve surgery in patients at high surgical risk, it remains a concern to identify which patients will benefit from this treatment. Some prognostic metrics have been reported to guide better patient selection; however, universal risk stratification measures have not been established. This study aimed to determine if age-adjusted Charlson co-morbidity index (CCI) could predict mortality in patients who underwent TMVr and to assess its discriminatory performance in long-term outcomes...

Statins have been shown to decrease stroke risk in patients with cardiovascular risk factors but not to prevent recurrence of ischemic stroke in patients with atrial fibrillation (AF). The present subanalysis aimed to clarify the efficacy of combined use of warfarin and statins in patients with nonvalvular AF (NVAF) with coronary artery disease, diabetes mellitus (DM), or hypertension. The effects of adding statins to warfarin were compared with those of warfarin alone in patients with NVAF with the data set of J-RHYTHM Registry, a prospective, observational study with a 2-year follow-up...

The new European Society of Cardiology guidelines reclassified heart failure according to left ventricular ejection fraction, recognizing patients with mid-range EF (mrEF; 40% to 49%) as a distinct group. We sought to investigate the clinical profile, in-hospital outcomes, and long-term mortality of ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention who had mrEF. We conducted a retrospective study of 2,086 consecutive patients with STEMI between December 2007 and June 2016 who underwent primary percutaneous coronary intervention and had a comprehensive echocardiographic examination performed within 72 hours of hospital admission...

Congenital long QT syndrome (LQTS) is characterized by QT prolongation with predisposition to life-threatening arrhythmia. There have been sporadic reports of LQTS coexisting with more common forms of congenital heart disease (CHD). However, the diagnosis of LQTS when CHD is present may be confounded by several common variables including postoperative electromechanical factors predisposing to ventricular arrhythmia, intrinsic, and postoperative QRS abnormalities. This report documents a single-center experience with patients who have both genetically confirmed LQTS and CHD to examine their modes of presentation and factors associated with making the diagnosis of LQTS in this patient population, as well as potential confounding variables that may mask or delay both LQTS diagnosis and initiation of therapy...

Data evaluating the impact of the periprocedural administration of novel oral anticoagulants (NOACs) on complications in the setting of pulmonary vein (PV) isolation using cryoballoon (CB) is limited. In the present study, our aim was to analyze procedural characteristics and incidence of complications in those patients who underwent CB ablation for atrial fibrillation and the impact of NOACs on adverse events compared with vitamin K antagonists (VKAs). Consecutive patients with drug resistant atrial fibrillation who underwent PV isolation by CB as index procedure were retrospectively included in our analysis...

Previous trials have found that statin therapy reduces low-density lipoprotein cholesterol (LDL-C) level and the risk of cardiovascular events. However, the benefit of statin therapy in patients with baseline LDL-C levels ≤ 50 mg/dl is less clear. Therefore, the aim of this study was to assess whether patients with acute myocardial infarction (AMI) who have baseline LDL-C levels ≤ 50 mg/dl would benefit from statin therapy in real-world clinical practice. We analyzed the clinical data of 1,048 patients (67...

Cardiac resynchronization therapy (CRT) improves cardiac hemodynamics. Therefore, the maintenance dose of loop diuretic therapy might be reduced. Consecutive patients who underwent CRT (n = 648) were retrospectively evaluated. Loop diuretic dose was recorded at baseline before implantation and 6 months later with patients classified into 4 groups: (1) no loop diuretic, (2) down-titration, (3) unchanged dose, and (4) up-titration. Afterward total loop diuretic exposure was calculated. Renal function trajectories were evaluated as the difference between implantation and censoring serum creatinine (Cr) value...

As transcatheter aortic valve replacement has become an alternative treatment for patients at high risk for surgical aortic valve replacement, bicuspid aortic valve (BAV) draws our attention again. The reported frequency of BAV was 0.5% to 2% in western population. However, there was no such epidemiologic study in Chinese population. Our study sought to investigate the prevalence and complications of BAV in China by echocardiographic database. A total of 668 cases who were confirmed with BAV, identified from 195,708 echocardiographic records of 157,039 patients in the echocardiographic database of West China Hospital (between June 2008 and June 2012), were analyzed retrospectively...

We aimed to study the association between the American Heart Association cardiovascular health (CVH) score and job strain in the Brazilian Longitudinal Study of Adult Health baseline. We analyzed data from 11,351 active workers (aged 35 to 74 years) without overt cardiovascular disease and who had complete data. Job strain was assessed using the 17-item Brazilian version of the Swedish Job Demand-Control-Support Questionnaire. Clinical (fasting plasma glucose, total cholesterol, and blood pressure) and lifestyle (diet, physical activity, smoking, and body mass index) components of CVH score were assessed according to the American Heart Association criteria...

In urban populations, worsening renal function (WRF) is well established in patients hospitalized with acute decompensated heart failure with preserved ejection fraction (HFpEF). However, the mechanisms for development of WRF in the setting of acute HF in HFpEF are unclear. In the present study, we sought to characterize conventional echocardiographic measures of right ventricular (RV) chamber size and function to determine whether RV dysfunction and/or adverse RV remodeling is related to WRF in patients with HFpEF...

Change in 6-minute walk distance (6MWD) has been used as a clinical marker in pulmonary hypertension. Determinants and worsening of 6MWD remain a matter of debate because nonpulmonary factors have an impact on the 6MWD. We hypothesized that future reduction of 6MWD in patients with systemic sclerosis (SSc) was more closely associated with cardiac dysfunction. We prospectively performed standard clinical and echocardiographic evaluations in SSc patients with the 6-minute walk test at enrollment. Features associated with the 6MWD were sought in a multiple linear regression analysis and compared using standardized β...

Carotid stenting (CAS) has been mainly offered to those patients considered at "high risk" for open carotid endarterectomy based on available data from large randomized clinical trials. However, several recent studies have called medical "high risk" into question for CAS indication. The REAL-1 trial evaluated the safety and perioperative and long-term effectiveness in patients with significant carotid artery stenosis with "high-risk" criteria treated with CAS and proximal protection device (MOMA) compared with those with standard surgical-risk features...

Once arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is diagnosed, the incidence of sudden cardiac death (SCD) is rare and prognosis is favorable, highlighting the value of early disease recognition. To inform strategies to diagnose ARVD/C before SCD, we sought to characterize clinical, genetic, and family history features of ARVD/C cases first recognized after SCD or resuscitated SCD (sudden cardiac arrest [SCA]). We identified 66 ARVD/C cases submitted to the Johns Hopkins ARVD/C Registry in whom disease was first recognized after SCD (n = 45) or SCA (n = 21) and compared their clinical, genetic, and demographic features with 352 patients (227 probands) diagnosed with ARVD/C by 2010 Task Force Criteria before any arrest...

We sought to examine the impact of calcific deposits on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The outcomes of 1,476 consecutive CTO PCIs performed in 1,453 patients (65.5 ± 10 years, 85% male) between 2012 and 2016 at 11 US centers were evaluated. Moderate or severe quantity of calcium was present in 58% of target lesions. Calcified lesions were more tortuous and more likely to have proximal cap ambiguity and interventional collaterals. PCI of moderately/severely calcified CTOs more often required use of the retrograde approach (54% vs 30%, p <0...

Historically, coronary artery bypass graft (CABG) surgery has been the standard revascularization method for unprotected left main coronary artery (LMCA) disease. Over the last decade, several randomized controlled trials (RCTs) have shown favorable results for percutaneous coronary intervention (PCI) with drug-eluting stent (DES) compared with CABG; however, no RCT has been conducted directly comparing DESs with medical therapy alone (MTA). Furthermore, the 2 most recently reported larger RCTs, using new-generation DESs reached somewhat conflicting conclusions comparing the 2 revascularization strategies...
