RATIONALE: Pulmonary arterial hypertension (PAH) is a devastating disease characterized by progressive vasoconstriction and obliterative vascular remodeling that leads to right heart failure (RHF) and death. Current therapies do not target vascular remodeling and RHF, and only result in modest improvement of morbidity and mortality. OBJECTIVE: To determine whether targeting HIF-2α with a HIF-2α-selective inhibitor could reverse PAH and RHF in different rodent PAH models...

A high mean platelet volume (MPV) level has been demonstrated to predict poor clinical outcomes in patients with cardiovascular disease. However, the relationship between MPV and mortality in patients with acute cardiorenal syndrome (ACRS) is unknown. Therefore, we investigated the predictive value of MPV for in-hospital mortality of patients with ACRS who received continuous renal replacement therapy (CRRT) in this study.We retrospectively analyzed the demographics, etiology, severity of illness, prognosis, and risk factors of ACRS patients who underwent CRRT in our hospital from January 2009 to December 2014...

Recent studies report that a single subtype of α1-adrenergic receptor (α1-AR), the α1A-subtype, mediates robust cardioprotective effects in multiple experimental models of heart failure, suggesting that the α1A-subype is a potential therapeutic target for an agonist to treat heart failure. Moreover, we recently found that the α1A-subtype is present in human heart. The goal of this study was to assess the inotropic response mediated by the α1A-subtype in human myocardium, and to determine if the response is down-regulated in myocardium from failing human heart...

Cardiac hypertrophy is one of the major risk factors for chronic heart failure. The role of endophilinA2 (EndoA2) in clathrin-mediated endocytosis and clathrin-independent endocytosis is well documented. In the present study, we tested the hypothesis that EndoA2 protects against angiotensin II (Ang II)-induced cardiac hypertrophy by mediating intracellular angiotensin II type 1 receptor (AT1-R) trafficking in neonatal rat cardiomyocytes (NRCMs). Cardiac hypertrophy was evaluated by using cell surface area and quantitative RT-PCR (qPCR) analyses...

Type 2 diabetes is a major and accelerating public health challenge. Between 1980 and 2014, a period of just 35 years, the number of adults with diabetes globally is estimated to have increased from 108 million to 422 million, due not only to sharply rising obesity rates, but also to increasing population size, and longer life expectancy. The increase in numbers is due to an increasing prevalence of diabetes worldwide, increasing population size, and longer life expectancy. Overall, worldwide age-standardized adult diabetes prevalence doubled from 4...

αE-catenin is a component of adherens junctions that link the cadherin-catenin complex to the actin cytoskeleton. The signaling function of this protein was recently revealed. In the present study, we investigated the role of αE-catenin in the pathogenesis of heart failure. We mated αE-catenin conditional knockout mice with αMHC-Cre mice and evaluated their mutant offspring. We found that αE-catenin knockout caused enlargement of the heart and atria, fibrosis, the upregulation of hypertrophic genes, and the dysregulation of fatty acid metabolism via the transcriptional activity of Yap and β-catenin...

PURPOSE OF THE REVIEW: Cardiovascular diseases (CVDs) are the principal killers of women. In this review, we summarize data regarding CVD and mortality after hypertensive disorders of pregnancy (HDP), and highlight clinical, research and policy needs to mitigate this risk. RECENT FINDINGS: Robust data indicate that women with HDP have substantially higher risk of future CVD, with a 3.7-fold increase in the risk of chronic hypertension, a 4.2-fold increase in the risk of heart failure, an 81% increase in the risk of stroke, and double the risk of atrial arrhythmias, coronary heart disease, and mortality when compared to women with normotensive pregnancies...

Type 2 diabetes (T2D) is associated with numerous comorbidities that significantly reduce quality of life, increase mortality and complicate treatment decisions. In a recent cardiovascular outcomes trial, Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME), the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin was shown to reduce cardiovascular (CV) mortality and heart failure in high-risk patients with T2D with a previous CV event or with established CV disease (CVD)...

Heart failure (HF) is a primary cause of morbidity and mortality worldwide. As the most widely studied and commonly applied natriuretic peptide (NP), B-type natriuretic peptide (BNP) has the effects of diuresis, natriuresis, vasodilation, anti-hypertrophy, and anti-fibrosis and it inhibits the renin-angiotensin-aldosterone and sympathetic nervous systems to maintain cardiorenal homeostasis and counteract the effects of HF. Both BNP and N-terminal pro B-type natriuretic peptide (NT-proBNP) are applied as diagnostic, managing, and prognostic tools for HF...

Congenital diveticula and aneurysm of the heart are rare and most often located at the apex of the left ventricle. They pose a significant risk for cardiac failure and arrhythmias. In contrast, nonapical diverticula of the right ventricle (RV) have a much more benign course. We present a child with Trisomy 21, atrioventricular septal defect, and large nonapical diverticulum of the RV that was neither addressed during surgery nor needed any medical treatment during 1-year follow-up.
