BACKGROUND: Vascular calcification is a major complication in chronic kidney disease (CKD) that increases the risk of adverse clinical outcomes. Geriatric nutritional risk index (GNRI) is a simple nutritional assessment tool that predicts poor prognosis in elderly subjects. The purpose of the present study was to evaluate the correlation between GNRI and severity of vascular calcification in non-dialyzed CKD patients.Methods and Results:We enrolled 323 asymptomatic CKD patients. To evaluate abdominal aortic calcification (AAC), we used aortic calcification index (ACI) determined on non-contrast computed tomography...

BACKGROUND: Brugada-type ECG (Br-ECG) is occasionally observed during acute myocardial ischemia of the right ventricular outflow tract (RVOT). No studies have explored, however, the association of ventricular tachyarrhythmia and development of Br-ECG due to acute ischemia of the RVOT.Methods and Results:The study included 13 consecutive patients with acute ischemia of the RVOT during coronary catheterization. Patients were divided into 2 groups: those with Br-ECG (group B) and those without (group N)...

It is almost a quarter of century that a pioneering work of 2 researchers named Brugada brought the entire scientific community to understanding the molecular, clinical, and electrophysiological aspects of a distinctive syndrome. It affects mainly young adults with syncope and/or sudden cardiac death caused by polymorphic ventricular tachycardia or ventricular fibrillation in the absence of any sign of cardiac degeneration or alteration. Although the involvement of the epicardial layer of the right ventricular outflow tract, and the requirement of pharmacologic challenge for unveiling concealed forms, have been fully characterized, many areas of uncertainties remain to be elucidated, such as the unpredictable usefulness of programmed ventricular stimulation, the role of radiofrequency catheter ablation for reducing ST-segment elevation, and the value of risk stratification in patients diagnosed with upper displacement of right precordial leads...

BACKGROUND: Alamandine is a newly discovered component of the renin-angiotensin system, which regulates blood pressure. In this study, the effect of alamandine on cardiovascular parameters in two-kidney, one clip (2K1C) hypertensive rats and normotensive rats, and the possible roles of the angiotensin II type 1 receptor (AT1R) and the PD123319-sensitive receptors in mediating this effect was investigated.Methods and Results:The cardiovascular parameters were monitored for 10 min before the infusion of the drugs or saline, and for 30 min afterward...

BACKGROUND: The neurohumoral and endothelial responses to the blood pressure (BP) lowering effects of heated water-based exercise (HEx) in resistant hypertension (HT) patients remain undefined.Methods and Results:We investigated these in 44 true resistant HT patients (age 53.3±0.9 years, mean±SEM). They were randomized and allocated to 2 groups, 28 to a HEx training protocol, which consisted of callisthenic exercises and walking in a heated pool for 1 h, three times weekly for 12 weeks and 16 patients to a control group maintaining their habitual activities...

BACKGROUND: Although there have been several reports on the risk factors associated with intima-media thickness (IMT), many questions remain. The purpose of this study was to investigate the association between IMT and cardiovascular risk factors in a Japanese general population.Methods and Results:The study group consisted of 1,583 male subjects undergoing routine health checkups. IMT of the common carotid artery was measured by high-resolution ultrasonography. Brachial-ankle pulse wave velocity (baPWV) was measured using an automated device...

Kathleen M Broughton, Mark A Sussman
Cardiovascular disease remains the leading cause of death worldwide and developing novel therapies to treat and cure the disease remains a high priority in the healthcare research community. Adult stem cells were successful in entering numerous clinical trials over the past 15 years in attempts to regenerate the heart. First-generation adult stem cell therapies for myocardial regeneration were highly promising in small animal models but realized benefits in humans were far more modest. Consequently, second-generation therapeutic approaches in early implementation phases have focused on enhancing cellular properties with higher survival and regenerative potential...

BACKGROUND: The aim of this study was to compare early and late outcomes of tricuspid valve replacement (TVR) and tricuspid valve repair (TVr) for severe tricuspid regurgitation (TR).Methods and Results:From 1994 to 2012, 360 patients (mean age, 58±13 years) with severe TR underwent TVR (n=97, 27%) or TVr (n=263, 73%). Among them, 282 patients (78%) had initial rheumatic etiology, and 307 patients (85%) had preoperative atrial fibrillation. The TVR group had higher total bilirubin, higher baseline central venous pressure, and higher incidence of previous cardiac operation...

BACKGROUND: In patients with myocardial infarction (MI), microvascular obstruction (MVO) determined by cardiac magnetic resonance imaging (CMR) is associated with left ventricular (LV) remodeling and worse prognosis.Methods and Results:In 71 patients with ST-segment elevation MI (STEMI) treated by primary percutaneous coronary intervention (PCI), speckle tracking echocardiography (STE) and CMR were performed early after PCI. All patients underwent CMR at 6 months after hospital discharge to assess the occurrence of LV remodeling...

BACKGROUND: In the EMPA-REG OUTCOME(®)trial, empagliflozin added to standard of care reduced the risk of 3-point major adverse cardiovascular (CV) events (3-point MACE: composite of CV death, non-fatal myocardial infarction, or non-fatal stroke) by 14%, CV death by 38%, hospitalization for heart failure by 35%, and all-cause mortality by 32% in patients with type 2 diabetes (T2DM) and established CV disease. We investigated the effects of empagliflozin in patients of Asian race.Methods and Results:Patients were randomized to receive empagliflozin 10 mg, empagliflozin 25 mg, or placebo...

BACKGROUND: The force-frequency relation (FFR) is a hemodynamic index of the chronotropic relationship between left ventricular (LV) systolic function (percent change in dP/dtmax) and elevation of heart rate. FFR is a marker of myocardial contractile reserve and follows an upward slope in healthy myocardium [monophasic FFR (MoF)], a pattern that becomes biphasic (BiF) under pathological conditions. However, it remains uncertain whether the FFR determines a patient's prognosis. We investigated the promising role of the FFR as a predictor of cardiac events in the setting of hypertrophic cardiomyopathy (HCM)...

Takahiro Komori, Kazuo Eguchi, Toshinobu Saito, Satoshi Hoshide, Kazuomi Kario
BACKGROUND: The cardiovascular prognosis of heart failure with preserved ejection fraction (HFpEF) has been shown to be similar to that of heart failure with reduced ejection fraction (HFrEF). It is unknown which factors predict cardiovascular outcome in HFpEF. We tested the hypothesis that the abnormal pattern of circadian blood pressure (BP) rhythm known as the riser BP pattern is associated with adverse outcomes in HFpEF.Methods and Results:We performed a prospective, observational cohort study of hospitalized HF patients who underwent ambulatory BP monitoring (ABPM)...

BACKGROUND: Obesity has been correlated with various adverse events in patients who receive left ventricular assist devices (LVAD). In this study, we sought to further characterize the role of obesity in this patient population.Methods and Results:We performed a retrospective analysis of 164 patients implanted with a HeartMate II from August 2008 to December 2014. Patients were categorized into 2 BMI groups based on WHO guidelines: BMI 18.5-30 kg/m(2)(n=99) and BMI >30 kg/m(2)(n=65)...
