The aims of the present study were to elucidate features of culprit lesion plaque morphology using optical coherence tomography (OCT) in relation to elevated serum uric acid (sUA) levels and to clarify the impact of sUA levels on adverse clinical outcomes in patients with acute coronary syndrome (ACS). Clinical data and outcomes were compared between ACS patients with sUA ≥6 mg/dl (high-sUA; n = 506) and sUA <6.0 mg/dl (low-sUA; n = 608). Angiography and OCT findings were analyzed in patients with preintervention OCT and compared between groups of high-sUA (n = 206) and low-sUA (n = 273)...

Although late-onset right-sided heart failure is recognized as a clinical problem in the treatment of patients with left ventricular assist devices (LVADs), the mechanism and predictors are unknown. Tricuspid valve (TV) deformation leads to the restriction of the leaflet motion and decreased coaptation, resulting in a functional tricuspid regurgitation that may act as a surrogate marker of late right-sided heart failure. This study aimed to investigate the association of preoperative TV deformation (annulus dilatation and leaflet tethering) with late right-sided heart failure development after continuous-flow LVAD implantation...

A high dose of oral flecainide has been used for acute termination of atrial fibrillation (AF) and atrial flutter or intra-atrial re-entry tachycardia (AFL-IART) in adults. The use of flecainide for these conditions in children has not been well described. We describe our institutional experience on acute termination of AF or AFL-IART in children with a single high dose of oral flecainide in a hospital setting. All patients who received a single high dose of oral flecainide from 2009 to 2016 who were <21 years of age were included...

For warfarin-treated patients with atrial fibrillation (AF) at low thromboembolic risk, recent studies have shown harm associated with periprocedural bridging using low-molecular-weight heparin. Clinician surveys have indicated a preference toward excessive bridging, especially among noncardiologists; however, little is known about actual practice patterns in these patients. We performed a retrospective evaluation of bridging in the setting of gastrointestinal endoscopy. We identified 938 patients with AF on warfarin who underwent esophagogastroduodenoscopy or colonoscopy between 2012 and 2016 at a tertiary health center...

In patients who underwent transcatheter aortic valve implantation (TAVI), postoperative mortality risk is commonly assessed with risk scores such as the Society of Thoracic Surgeons-Postoperative Risk of Mortality (STS-PROM) and EuroSCORE II, in which age plays a dominant role. However, we reason that in the naturally selected oldest-old patients (nonagenarians), this may not be completely justified and that therefore age should play a minor role in decision-making. The objective of this study was to compare procedural outcome and mid-term mortality of transfemoral (TF)-TAVI patients aged ≥90 years with patients aged <90 years...

Diabetes mellitus (DM) is a known risk factor for myocardial infarction (MI); however, data regarding MI subtypes in people with diabetes are limited. In the Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER) trial (n = 9,340), liraglutide significantly reduced the risk of major adverse cardiovascular (CV) events (composite of CV death, nonfatal MI, or nonfatal stroke) versus placebo in patients with type 2 DM and high CV risk. Liraglutide also reduced risk of first MI (292 events with liraglutide vs 339 with placebo)...

Arrhythmic risk stratification in idiopathic dilated cardiomyopathy (IDC) remains a major concern. As the ventricles remodel in time, risk factors for arrhythmic death may change. A cohort of 710 patients with idiopathic dilated cardiomyopathy, without previous ventricular arrhythmias, was retrospectively studied to understand how risks vary in time. The primary end point was a composite of sudden cardiac death, ventricular fibrillation, sustained ventricular tachycardia, and appropriate implantable cardioverter-defibrillator interventions...

Reports on pulmonary hypertension (PH) in the aging congenital heart disease (CHD) population are few and focused on arterial PH and patients with systemic-to-pulmonary shunts. Our objective was to estimate incidence and mortality of adult-onset PH in the CHD population. Using Danish nationwide registries, we identified all patients diagnosed with CHD from 1963 to 1974 and 1977 to 2012. Patients were matched 1:10 by birth year and gender with general population subjects. Between 1977 and 2013 adults >18 years of age were followed up until PH diagnosis, death, or emigration, whichever came first, using data from the Danish National Registry of Patients...

There has been no established echocardiographic parameter to accurately assess left ventricular (LV) relaxation. Impaired LV relaxation assessed by the time constant of LV pressure decline (Tau) is one of the major components of diastolic dysfunction. We sought to noninvasively estimate Tau (eTau) by speckle tracking echocardiography (STE) and to validate the eTau against Tau by catheterization. Tau was reported to be calculated using the isovolumic relaxation time (IVRT), LV end-systolic pressure, and left atrial (LA) pressure...

The aim of this study was to assess the relation of wrist circumference with changes in left ventricular (LV) structure in a population of overweight/obese children and adolescents. One hundred and six children and adolescents were consecutively enrolled. In all subjects body weight, height, wrist circumference, waist circumference, body mass index-standard deviation score, fasting glucose, insulin, lipid profile, and blood pressure were evaluated. All subjects underwent echocardiographic assessment, and the following parameters were evaluated: LV dimension at end diastole and LV dimension at end systole, LV posterior wall thickness at end diastole and LV posterior wall thickness at end systole, interventricular septal thickness at end diastole and interventricular septal thickness at end systole, LV mass, and epicardial adipose tissue (EAT)...

This study sought to investigate the safety of percutaneous left atrial appendage (LAA) occlusion for stroke prevention in patients with nonvalvular atrial fibrillation who have LAA thrombus. From October 2010 to October 2016, LAA occlusions were performed in facilities within a Korean multicenter registry in patients without (n = 132) or with (n = 10) LAA thrombus (detected during preprocedural assessments). The incidences of periprocedural complications, including stroke, pericardial tamponade, major bleeding, and device embolization, were assessed and compared between the groups...

It is unknown whether the association of high-sensitivity troponin I (hs-TnI) with adverse cardiovascular outcomes varies by the presence of chronic kidney disease (CKD). We examined the association of hs-TnI with adverse cardiovascular outcomes in those with and without CKD in 4,107 (mean age, 64 years; 63% men; 20% black) patients from the Emory Cardiovascular Biobank who underwent coronary angiography. CKD (n = 1,073) was defined as estimated glomerular filtration rate <60 ml/min/1.73 m2 or urine albumin/creatinine ratio >30 mg/g at baseline...

Because the Japan Professional Baseball Championship Series (Japan Series) is a stressful sports event, it is possible that watching Japan Series matches may increase the risk of cardiovascular events. Therefore, we investigated the potential association between the Japan Series and the incidence of out-of-hospital cardiac arrest (OHCA) events. National registry data for all cases of OHCA between 2005 and 2014 from 47 prefectures of Japan were obtained. We used a time-stratified case-crossover design with a conditional Poisson regression model to compare OHCA events during the Japan Series with those events that occurred during the periods except for dates of the Japan Series...

We have previously shown a reduction in HF events with cardiac resynchronization therapy with defibrillator (CRT-D) in patients with mild heart failure (HF) and diabetes mellitus (DM). It remains unknown whether HF remission in DM patients with CRT-D translates into reduced mortality. The effects of CRT-D versus an implantable cardioverter-defibrillator (ICD) alone to reduce long-term mortality were assessed in patients with left bundle branch block with DM (n = 386) and without DM (n = 982), enrolled in the Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy (MADIT-CRT)...

We aimed to characterize of the role of insulin-like growth factor-binding protein 7 (IGFBP-7) in heart failure (HF) pathophysiology. IGFBP-7 has been associated with cardiac hypertrophy and diastolic dysfunction in HF. In 86 patients with HF with a preserved ejection fraction (HFpEF) (ejection fraction [EF] ≥45%) and 79 with HF with a reduced ejection fraction (HFrEF), we assessed concentrations of serum IGFBP-7, correlations between serum IGFBP-7 and clinical data, diastolic function, and associations with outcome...

The objective of this study was to evaluate the financial implications and the impact of pre-existing atrial fibrillation (AF) on in-hospital outcomes in patients who underwent transcatheter aortic valve implantation (TAVI) using the Nationwide Inpatient Sample (NIS) database. We identified patients who underwent TAVI from 2011 to 2014. The primary end point was the effect of pre-existing AF on in-hospital mortality. Secondary end points included periprocedural cardiac complications, stroke, and hemorrhage requiring transfusion...

Although depressive disorders have been associated with increased risk of worse outcomes with cardiovascular diseases (CVDs), its relation with access to and quality of cardiovascular care is not well studied. Accordingly, we sought to assess the association between depressive disorders and access and quality of care among United States veterans with CVD. The 2013 Centers for Disease Control's Behavioral Risk Factor Surveillance Survey was utilized to identify a cohort of 13,126 veterans with CVD. Demographic and clinical history were recorded in adults with and without a depressive disorder (defined as self-reported diagnosis of depression, major depression, minor depression, or dysthymia)...
