Heart failure patients are classified by ejection fraction (EF) into distinct groups: heart failure with preserved ejection fraction (HFpEF) or heart failure with reduced ejection fraction (HFrEF). Although patients with heart failure commonly have multiple comorbidities that complicate management and may adversely affect outcomes, their role in the HFpEF and HFrEF groups is not well-characteri...

Cardiovascular risk factors are a significant burden in chronic kidney disease (CKD). Abnormalities of left ventricle (LV) structure and function are present in 70-80% of patients with CKD and more than half of them die of cardiovascular diseases. In this study we aimed to correlate, parathyroid hormone (PTH) levels with left ventricular hypertrophy (LVH) and LV ejection fraction by 2D-Echo-CD ...

To determine the possible relationship between left ventricular dilatation and heart rate changes provoked by the Valsalva maneuver (Valsalva ratio), we studied 9 patients with isolated chronic aortic insufficiency. Left ventricular systolic function was assessed by two-dimensional echocardiography and cardiac catheterization. All patients were asymptomatic (functional class I of the New York H...

Background:Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LV...

Introduction: During coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass (CPB), the role of cardioplegic solution which results in cardiac arrest, is critical. This study was planned to evaluate the clinical impacts of N acetylcysteine (NAC) enriched cold-blood cardioplegia on early reperfusion injury in patients with ischaemic heart disease undergoing CABG Methods: In a...

INTRODUCTION The myocardial performance index (MPI) has been described as a non-invasive Doppler measurement of ventricular function. The aim of this study was to assess MPI following surgical correction of ventricular septal defect (VSD) and to evaluate its impact on postoperative recovery. MATERIAL AND METHODS This is a prospective study involving 30 children (16 girls and 14 boys) operated...

BACKGROUND Left ventricular (LV) remodeling following acute myocardial infarction (MI) is difficult to predict at an individual level although a possible interfering role of vascular function has yet to be considered to date. This study aimed to determine the extent to which this LV remodeling is influenced by the concomitant evolution of vascular function and LV loading conditions, as assessed...

Objective: To identify electrocardiographic parameters that predict extent of early improvement in ejection fraction (EF) in patients with stress cardiomyopathy. Methods: We collected baseline clinical, ECG and imaging data and follow up echocardiography data on 30 consecutive patients with stress cardiomyopathy. The relationship between baseline ECG parameters and Delta EF was evaluated by uni...
