BACKGROUND
Anemia is common in patients with chronic heart failure (CHF) and is associated with a poor prognosis. However, only a minority of patients with CHF have impaired renal function or underlying hematinic deficiencies. It has been shown that inhibition of the renin-angiotensin system is
Heart disease is associated with the accumulation of resident cardiac fibroblasts (CFs) that secrete extracellular matrix (ECM), leading to the development of pathological fibrosis and heart failure. However, the mechanisms underlying resident CF proliferation remain poorly defined. Here, we report
The benefits of physical activity in cardiovascular diseases have long been appreciated. However, the molecular mechanisms that trigger and sustain the cardiac benefits of exercise are poorly understood, and it is anticipated that unveiling these mechanisms will identify novel therapeutic targets.
Myocardial infarction (MI) in mice results in cardiac rupture at 4-7 days after MI, whereas cardiac fibrosis and dysfunction occur later. N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) has anti-inflammatory, anti-fibrotic, and pro-angiogenic properties. We hypothesized that Ac-SDKP reduces
Common models of chronic heart failure (CHF) do not always result in parameters and symptoms that can be extrapolated to the clinical situation of patients with end-stage heart failure. The aim of this study was to establish and validate a new model of CHF in the rat. CHF was induced in Wistar Kyoto
Heart failure is a leading cause of death and disability. Galectin-3 expression is associated with myocardial fibrosis; recombinant galectin-3 can induce myocardial fibrosis in experimental animals. However, the fact that endogenous galectin-3 is causative of myocardial fibrosis is yet to be firmly
Inflammation may play an important role in the pathogenesis of cardiac fibrosis in heart failure (HF) after myocardial infarction (MI). N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) is a naturally occurring antifibrotic peptide whose plasma concentration is increased 4- to 5-fold by
The hypotensive effects of N-[8-amino-1(S)-carboxyoctyl] -L-alanyl-L-proline (AB-47, CAS 120008-53-9) were examined in normotensive rats and various hypertensive rat models. The hemodynamic effect of AB-47 was also examined in anesthetized spontaneously hypertensive rats (SHR). In 2-kidney, 1-clip
Sampatrilat is a novel vasopeptidase inhibitor that may offer a greater benefit than traditional angiotensin-converting enzyme (ACE) inhibitors in the treatment of chronic heart failure (CHF). The present study was undertaken to determine whether sampatrilat improves hemodynamic function and cardiac
Mitochondria provide an environment conducive to mutations in DNA molecules (mtDNA). Analyses of mtDNA have shown mutations potentially leading to many cardiovascular traits. Here, we describe a patient with dilated cardiomyopathy and new mtDNA duplication. The patient presented symptoms of heart
BACKGROUND
The regulatory cytokine transforming growth factor (TGF)-beta1 is thought to play a role in atherosclerotic heart disease as well as in idiopathic cardiomyopathy. The production of TGF-beta1 is genetically controlled as polymorphisms in the signaling sequence of the TGF-beta1 gene
In the failing heart, an imbalance in matrix metalloproteinases (MMPs) and their biological regulators, the tissue inhibitors of MMPs (TIMPs), may result in cardiac dilatation from matrix degradation. We hypothesized that a reduction of myocardial TIMP-3 is associated with adverse matrix remodeling
OBJECTIVE
This study was designed to compare different proposed methods of assessing adherence with angiotensin-converting enzyme (ACE) inhibitor (ACEI) therapy in chronic heart failure.
BACKGROUND
The use of ACEIs in chronic heart failure gives us a unique opportunity to assess a patient's
OBJECTIVE
Diabetic nephropathy is the main cause of end-stage renal disease. N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP), a physiological tetrapeptide hydrolyzed by the angiotensin-converting enzyme (ACE), has antifibrotic effects in the cardiovascular system and in the kidney in experimental
Vasopeptidase inhibitors possess dual inhibitory actions on neutral endopeptidase (NEP) and angiotensin-converting enzyme (ACE) and have beneficial effects on cardiac remodeling. However, the contribution of NEP inhibition to their effects is not yet fully understood. To address the role of cardiac
