Peripheral vascular endothelial function in patients with hypertrophic cardiomyopathy.

Abstract

Patients with hypertrophic cardiomyopathy (HC) have coronary microvascular dysfunction, which is an independent predictor of adverse left ventricular remodeling, systolic dysfunction, and mortality in these patients. Whether these defects in vasomotor function are localized to the coronary arteries or whether systemic vasomotor dysfunction is present in patients with HC has not yet been adequately examined. The aim of this study was to test the hypothesis that patients with HC have altered peripheral vascular endothelial function. Subjects without coronary artery disease (CAD) and those with CAD served as negative and positive controls, respectively. Conduit artery endothelium-dependent vasomotion was assessed with ultrasound by measuring flow-mediated dilation of the brachial artery. Flow-mediated dilation was lower in patients with HC compared with those without CAD (p <0.05) but was similar in patients with CAD (p = NS). In conclusion, vasomotor dysfunction in HC is not restricted to the coronary vasculature. Patients with HC have impaired peripheral conduit vessel endothelial function, and the magnitude of impairment is similar to that seen in older patients with advanced CAD.

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
