Heart failure (HF) is a major health and economic burden in developed countries. It has been proposed that the pathogenesis of HF may involve the action of mitochondria. We evaluate three different mouse models of HF: tachycardiomyopathy, HF with preserved left ventricular (LV) ejection fraction

HIV protease inhibitors that block GLUT4 precipitate acute, decompensated heart failure in a mouse model of dilated cardiomyopathy.

The clinical use of HIV protease inhibitors is associated with insulin resistance and other metabolic changes that increase long-term cardiovascular risk. Since the failing heart has increased reliance on glucose, the influence of drug exposure on glucose homeostasis, myocardial glucose uptake,

BACKGROUND The Inhibition of Metallo Protease by BMS-186716 in a Randomized Exercise and Symptoms Study in Subjects With Heart Failure (IMPRESS) clinical trial randomized patients with congestive heart failure to a daily regimen of either omapatrilat or lisinopril. At 24 weeks, patients randomized

Levels of von Willebrand factor antigen and von Willebrand factor cleaving protease (ADAMTS13) activity predict clinical events in chronic heart failure.

Decreased activity of ADAMTS13, the von Willebrand factor (VWF) cleaving protease, was recently reported in cardiovascular diseases and in hepatic failure. Chronic heart failure (CHF) is characterised by abnormalities of left ventricular function accompanied by the failure of the liver and

BACKGROUND Incident heart failure (HF) is increased in persons with human immunodeficiency virus (PHIV). Protease inhibitors (PIs) are associated with adverse cardiac remodeling and vascular events; however, there are no data on the use of PIs in PHIV with HF. OBJECTIVE This study sought to compare

Protease activated receptor-2 contributes to heart failure.

Heart failure is a major clinical problem worldwide. Previous studies have demonstrated an important role for G protein-coupled receptors, including protease-activated receptors (PARs), in the pathology of heart hypertrophy and failure. Activation of PAR-2 on cardiomyocytes has been shown to induce

Role of various proteases in cardiac remodeling and progression of heart failure.

It is believed that cardiac remodeling due to geometric and structural changes is a major mechanism for the progression of heart failure in different pathologies including hypertension, hypertrophic cardiomyopathy, dilated cardiomyopathy, diabetic cardiomyopathy, and myocardial infarction. Increases

We examined the hypothesis that oxidants generated nitroso derivatives, activated latent matrix metalloproteinase (MMP), and induced proteinase-activated receptor 1 (PAR-1), leading to disconnection between the endothelium and myocytes. Administration of cardiospecific tissue inhibitor of

OBJECTIVE To observe myocardial cathepsin (Cat) S expression and activity in hypertensive heart failure rats. METHODS The expression and activity of Cat S were determined in the left ventricular (LV) myocardium (LVM) of Dahl salt-sensitive rats fed either a high-salt (HS, 8%) or low-salt (LS, 0, 3%,

The coagulation protease cascade plays an essential role in hemostasis. In addition, a clot contributes to host defense by limiting the spread of pathogens. Coagulation proteases induce intracellular signaling by cleavage of cell surface receptors called protease-activated receptors (PARs). These

Cardiovascular disease is a major cause of death and thus a great deal of effort has been made in salvaging the diseased myocardium. Although various factors have been identified as possible causes of different cardiac diseases such as heart failure and ischemic heart disease, there is a real need

Cardiac sodium (Na(+))-calcium (Ca(2+)) exchanger 1 (NCX1) is central to the maintenance of normal Ca(2+) homeostasis and contraction. Studies indicate that the Ca(2+)-activated protease calpain cleaves NCX1. We hypothesized that calpain is an important regulator of NCX1 in response to pressure
