BACKGROUND The South African Heart Association (SA Heart) is an affiliate of the European Society of Cardiology (ESC). SA Heart endorses ESC treatment guidelines with modification to suit local circumstances. The Heart Failure Society of South Africa (HeFSSA) is a special interest group of SA Heart. This guideline has been compiled on behalf of the HeFSSA and is based on the ESC guidelines for ...
24 Heart failure (HF) as a clinical syndrome is posing an increasing social and economic burden, particularly in developed countries with their ageing populations.1 No single pathophysiological mechanism can explain the clinical manifestations of HF, which presents as the unfavourable endpoint of a many cardiac diseases; most commonly ischaemic heart disease, hypertension, idiopathic dilated ca...
BACKGROUND The goal of this study was to determine if left ventricular (LV) global longitudinal strain (GLS) predicts heart failure (HF) readmission in patients with acute decompensated heart failure. METHODS AND RESULTS Two hundred ninety one patients were enrolled at the time of admission for acute decompensated heart failure between January 2011 and September 2013. Left ventricle global lo...
BACKGROUND Abnormal sleep dynamics in patients with heart failure is one of the mechanisms for the relative predominance of central sympathetic outflow over parasympathetic tone. This study was designed to examine whether central sympathoinhibition could improve the sympathovagal imbalance related to rapid-eye-movement (REM)/non-REM ultradian sleep rhythm in these patients. METHODS AND RESULT...
BACKGROUND Chronic kidney disease (CKD) has been linked to higher heart failure (HF) risk. Anemia is a common consequence of CKD, and recent evidence suggests that anemia is a risk factor for HF. The purpose of this study was to examine among patients with HF, the association between CKD, anemia and inhospital mortality and early readmission. METHODS We performed a retrospective cohort study ...
BACKGROUND We previously reported that the fixed-dose combination of isosorbide dinitrate and hydralazine hydrochloride (FDC I/H) significantly decreased the risk of all-cause death and first hospitalization for heart failure (HF) and improved quality of life in patients with New York Heart Association class III or IV heart failure in the African-American Heart Failure Trial (A-HeFT). The curre...
BACKGROUND Ischemic heart disease (IHD) is the most common cause of heart failure (HF); however, the role of revascularization in these patients is still unclear. Consensus on proper use of cardiac imaging to help determine which candidates should be considered for revascularization has been hindered by the absence of clinical studies that objectively and prospectively compare the prognostic in...
Background Characterizing myocardial mechanical properties is valuable in understanding cardiomyopathy with and without clinical heart failure (HF). We sought to examine the incremental value of strain assessment in patients with left ventricular systolic dysfunction without HF (LVSD), HF with reduced ejection fraction (HFrEF), LV diastolic dysfunction without HF (LVDD) and HF with preserved EF...
The study was conducted to examine the effects of ICI 118,551 on the systolic function of cardiac muscle cells of rats in heart failure and determine the molecular mechanism of selective β2-adrenergic receptor (β2-AR) antagonist on these cells. The chronic heart failure model for rats was prepared through abdominal aortic constriction and separate cardiac muscle cells using the collagenase dige...
BACKGROUND Microalbuminuria is considered a major risk factor predisposing to cardiovascular morbidity and mortality. Microalbuminuria levels in patients with or without diabetes have been associated with a higher risk of chronic heart failure (HF). However, there are limited data regarding prevalence of microalbuminuria in chronic heart failure and its prognostic value. The aim of this study w...
