Beneficial effects of statins in patients with non-ischemic heart failure
Tóm tắt
HMG CoA reductase inhibitors (statins) may exert a wide
array of cholesterolindependent effects including
antihypertrophic effects on the heart. Their role in the
treatment of heart failure has not been studied. 15 patients with heart failure NYHA II-III based on
non-ischemic dilated cardiomyopathy were randomized in a
double-blind study to 0.4 mg cerivastatin or placebo for an
average treatment period of 20 weeks. Quality of life and
exercise capacity increased significantly in the statin
treatment but not in the placebo group (Minnesota Living with
Heart Failure Questionnaire, 6 min walking test). Concomitantly,
there was a trend towards increased left ventricular ejection
fraction (radionuclear ventriculography) and improved
endothelial function (forearm blood flow). Statins decreased
plasma concentrations of troponine T, high sensitive C-reactive
protein (hsCRP), plasminogen activator inhibitor-1 (PAI-1) and
tumor necrosis factor alpha (TNFα). Statins induce benefical effects in patients with
non-ischemic cardiomyopathy leading to improvement of quality of
life and exercise capacity disclosing a promising novel
treatment strategy for patients with heart failure.
