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

Small proline-rich protein 2B drives stress-dependent p53 degradation and fibroblast proliferation in heart failure.

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.

N-acetyl-seryl-aspartyl-lysyl-proline treatment protects heart against excessive myocardial injury and heart failure in mice.

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

A model of chronic heart failure in spontaneous hypertensive rats (SHR).

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

Personalizing biomarker strategies in heart failure with galectin-3.

Přihlášení Registrace

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

Ac-SDKP reverses inflammation and fibrosis in rats with heart failure after myocardial infarction.

Přihlášení Registrace

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

Hypotensive and hemodynamic effects of the new non-sulfhydryl angiotensin converting enzyme inhibitor N-[8-amino-1(S)-carboxyoctyl]-L-alanyl-L-proline.

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

Beneficial effects of sampatrilat, a novel vasopeptidase inhibitor, on cardiac remodeling and function of rats with chronic heart failure following left coronary artery ligation.

Přihlášení Registrace

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

A new duplication in the mitochondrially encoded tRNA proline gene in a patient with dilated cardiomyopathy.

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

TGF-beta1 gene polymorphisms in patients with end-stage heart failure.

Přihlášení Registrace

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

Matrix remodeling in experimental and human heart failure: a possible regulatory role for TIMP-3.

Články mohou překládat pouze registrovaní uživatelé

Přihlášení Registrace

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

Nonadherence with angiotensin-converting enzyme inhibitor therapy: a comparison of different ways of measuring it in patients with chronic heart failure.

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

Renal antifibrotic effect of N-acetyl-seryl-aspartyl-lysyl-proline in diabetic rats.

Přihlášení Registrace

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

Direct inhibition of neutral endopeptidase in vasopeptidase inhibitor-mediated amelioration of cardiac remodeling in rats with chronic heart failure.

Články mohou překládat pouze registrovaní uživatelé

Přihlášení Registrace

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
