To investigate right ventricular function in hemodialysis patients with preserved left ventricular ejection fraction (LVEF) using twodimensional speckle tracking echocardiography. Methods: Patients with end-stage kidney disease (ESKD) who were on regular hemodialysis and had preserved LVEF and a group of age- and sex-matched control subjects were recruited for the study in Bach Mai Hospital.

Many patients with heart failure (HF) with reduced ejection fraction (HFrEF) have improved or restored left ventricular ejection fraction (LVEF). Within context heart failure with recovered or improved ejection fraction (HFiEF) has been proposed as a new category of HF.

Moyamoya disease (MMD) was first used as a descriptor for a stenoocclusive process that affects primarily the internal carotid arteries (ICA) in a bilateral fashion in 1969. Characterized by recurrent ischemic events in the developing brains of young patients, the process is one that often decimates the quality of life of affected individuals.

In patients undergoing cardiac surgery, a reduced preoperative left ventricular ejection fraction (LVEF) is common and is associated with a worse outcome. Available outcome data for these patients address specific surgical procedures, mainly coronary artery bypass graft (CABG). Aim of our study was to investigate perioperative outcome of surgery on patients with low pre-operative LVEF undergoing a broad range of cardiac surgical procedures.

Hypoxia affects myocardial oxygen supply resulting in subclinical cardiac dysfunction in obstructive sleep apnea (OSA) patients, with cardiovascular complications being associated with increased oxidative burst (OB). The aims of our study were to assess left ventricular (LV) dynamic myocardial deformation and diastolic reserve at rest and upon exercise, along with OB determination in this patients subset.

Takotsubo cardiomyopathy (TC) is characterized by a transient decrease in ejection fraction and a reversible left ventricular dysfunction. The pathophysiology of TC is not completely understood. Heterogeneous and multifactorial mechanisms are involved: drugs, emotional and physical stress, genetic and hormonal factors.

Epicardial adipose tissue has been proposed to participate in the pathogenesis of heart failure. The aim of our study was to assess the expression of thermogenic genes (Uncoupling protein 1 (UCP1), peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α), and PR-domain-missing 16 (PRDM16) in epicardial adipose tissue in patients with heart failure, stablishing the difference according to left ventricular ejection fraction (reduced or preserved).
