Background— Chronic heart failure is associated with inflammation and neurohormonal imbalance. The 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase inhibitors, or statins, exert anti-inflammatory and vascular protective effects. We hypothesized that short-term statin therapy may have beneficial effects in patients with nonischemic heart failure.

Methods and Results— Sixty-three patients with symptomatic, nonischemic, dilated cardiomyopathy were randomly divided into 2 groups. One group received simvastatin (n=24), and the other group received placebo (n=27). The initial dose of simvastatin was 5 mg/d, which was increased to 10 mg/d after 4 weeks. After 14 weeks, patients receiving simvastatin exhibited a modest reduction in serum cholesterol level compared with patients receiving placebo (130±13 versus 148±18, P<0.05). Patients treated with simvastatin had a lower New York Heart Association …
