BACKGROUND: Mid-diastolic mitral forward flow (L wave) is occasionally detected in heart failure (HF), but its correlates and prognostic value are still unknown, particularly in light of the type of HF, that is, HF with preserved or with reduced ejection fraction (HFpEF, HFrEF).Methods and Results:Of 151 patients with HF, L wave was observed in 23 of 82 HFrEF patients and in 25 of 69 HFpEF patients. Mitral early diastolic velocity (E), the ratio of E to mitral annulus velocity, and left atrial volume index were greater in the patients with L wave than in those without L wave in both subsets...

BACKGROUND: The aim of the current study was to identify the distribution of length and cost of hospital stay and their associated risk factors in poor-risk Japanese critical limb ischemia (CLI) patients undergoing revascularization.Methods and Results:We analyzed prospectively collected data from 507 CLI patients who required assistance in their daily lives due to disability in activities of daily living and/or cognitive function impairment and who underwent revascularization. The median length and cost of hospital stay were 23 days (IQR, 9-52 days) and ¥2...

BACKGROUND: Recurrent ventricular tachyarrhythmias (VTA) are "A factor" modifiers in the Interagency Registry for Mechanically Assisted Circulatory Support profile. The effect of recurrent VTA on clinical outcome, however, is controversial. We evaluated the impact of recurrent VTA on outcome in Japanese heart transplant candidates with a left ventricular assist device (LVAD).Methods and Results:Sixty-six adult patients with advanced heart failure who were listed for heart transplantation between January 2005 and October 2017 were enrolled in the study...

BACKGROUND: Physical activity is associated with lower risk of coronary and cerebrovascular disease but its potential role in prevention of aortic valve stenosis (AVS) is unclear.Methods and Results:We investigated whether physical activity influences AVS risk in a cohort of 69,288 adults. During a mean follow-up of 15.3 years, 1,238 AVS cases were diagnosed. No associations were observed between AVS and walking/bicycling (≥1 h/day vs. almost never: hazard ratio 0.92, 95% CI 0.74-1...

BACKGROUND: Alamandine differs from angiotensin-(1-7) in a single N-terminal alanine residue. The aim of this study was to investigate whether alamandine protects the heart against reperfusion injury.Methods and Results:After euthanizing Sprague-Dawley rats, hearts were perfused with Krebs-Henseleit buffer for a 20-min pre-ischemic period with or without alamandine, followed by 20 min global ischemia and 50 min reperfusion. Alamandine (0.1 mg/kg) improved the postischemic left ventricular developed pressure and ±dP/dt, decreased the infarct size, and decreased the lactate dehydrogenase levels in the effluent...

BACKGROUND: Despite the revolution of coronary stents, there remain concerns about the risk of stent thrombosis, especially in patients with ST-elevation myocardial infarction (STEMI). The present study compared early vascular healing as a contributing factor to reducing stent thrombosis between Xience everolimus-eluting stents (X-EES) and Synergy everolimus-eluting stents (S-EES) in patients with STEMI.Methods and Results:The present study included 47 patients with STEMI requiring primary percutaneous coronary intervention with X-EES (n=25) or S-EES (n=22)...

BACKGROUND: Pulmonary arterial (PA) wall thickening evaluated by optical coherence tomography (OCT) has been reported in adults with PA hypertension. The purpose of this study was to evaluate the feasibility of OCT for preoperative assessment of the PA wall in children with congenital heart disease (CHD).Methods and Results:Participants comprised 39 patients with ventricular septal defect, atrial septal defect, or patent ductus arteriosus. Attempts were made to evaluate vessels of various diameters using OCT...

BACKGROUND: We have previously demonstrated that umbilical cord plasma natriuretic peptide (NP) levels reflect the severity of heart failure (HF) in fetuses with congenital heart defects (CHD). The aim of this study was to evaluate the significance of amniotic fluid (AF) NP levels in the assessment of HF in fetuses with CHD or arrhythmia.Methods and Results:This was a prospective observational study at a tertiary pediatric cardiac center. A total of 95 singletons with CHD or arrhythmia, and 96 controls from 2012 to 2015 were analyzed...

BACKGROUND: In a previous study, a low level of miR-126-3p in endothelial progenitor cells (EPCs) was linked to the outcome of ischemic cardiomyopathy (ICM) patients. However, it remains unclear whether transplantation with miR-126-3p-overexpressing EPCs (MO-EPCs) can improve the cardiac function of ICM animal models.Methods and Results:miR-126-3p overexpression by lentiviral vector significantly increased migration and tube-like structures of EPCs from ICM patients. MO-EPCs or non-modified EPCs (NM-EPCs) were transplanted into nude rats with ICM induced by coronary artery ligation...

BACKGROUND: Our aim was to investigate the baseline clinical and echocardiographic parameters for predicting left ventricular (LV) dysfunction after anthracycline chemotherapy and heart failure (HF) hospitalization in a single cancer disease.Methods and Results:We studied 73 patients with malignant lymphoma and preserved LV ejection fraction (LVEF). Echocardiography was performed before and after anthracycline chemotherapy. Global longitudinal strain (GLS) was determined from 3 standard apical views...

BACKGROUND: It is unclear whether renal dysfunction affects warfarin control in patients with non-valvular atrial fibrillation (NVAF).Methods and Results:Using a dataset from the J-RHYTHM Registry, time in therapeutic range (TTR) of the international normalized ratio (INR) of prothrombin time, and creatinine clearance (CrCl) were determined in elderly patients aged ≥70 years. Target INR values were 1.6-2.6 following Japanese guidelines. Incidences of thromboembolism, major hemorrhage, and all-cause death were determined over 2 years...

BACKGROUND: Although the coronary artery calcium score (CACS) is a prognostic measurement in asymptomatic individuals, it is measured in symptomatic patients using coronary computed tomography angiography (CCTA). We aimed to examine the predictive value of the CACS for mid- to long-term cardiovascular mortality and morbidity in patients who underwent CCTA.Methods and Results:We studied 736 patients with suspected coronary artery disease (CAD) who underwent CCTA. During a median follow-up period of 6...
