Rosuvastatin to Prevent Vascular Events in Men and Women With Elevated C-Reactive Protein

Abstract

Previous studies have shown that statin therapy reduces high-sensitivity C-reactive protein levels as well as cholesterol, but no prospective trials have directly addressed the issue of whether elevated levels of high-sensitivity C-reactive protein are beneficial for apparently healthy persons with levels of LDL cholesterol below current thresholds for treatment. This randomized, double-blind, placebo-controlled, multicenter trial study was part of the Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin (JUPITER) Study. The present study evaluated the effects of rosuvastatin, 20 mg daily, or placebo in 17,802 apparently healthy men and women with LDL cholesterol levels of less than 130 mg per deciliter (3.4 mmol per liter) and high-sensitivity C-reactive protein levels of 2.0 mg per liter or higher. Following randomization, study subjects were followed for the occurrence of the combined primary end point: myocardial infarction, stroke, arterial revascularization, hospitalization for unstable angina, or death from cardiovascular causes. The trial was terminated after a median follow-up of 1.9 years (maximum, 5.0). As compared with the placebo at the 12-month visit, rosuvastatin reduced LDL cholesterol levels by 50%, high-sensitivity C-reactive protein levels by 37%, and triglyceride levels by 17% (P < .001 for all three comparisons). For rosuvastatin and placebo, the rates of the primary end point were 0.77 and 1.36 per 100 person-years of follow-up, respectively; the hazard ratio (HR) for rosuvastatin was 0.56, with a 95% confidence interval [CI] of 0.46–0.69 (P < .00001). The rates of the individual components of the primary trial end point for rosuvastatin and placebo, respectively, were as follows: (1) 0.17 and 0.37 for fatal or nonfatal myocardial infarction (HR, 0.46; 95% CI, 0.30– 0.70; P < .0002); (2) 0.18 and 0.34 for fatal or nonfatal stroke (HR, 0.52; 95% CI, 0.34–0.79; P < .002); (3) 0.41 and 0.77 for arterial revascularization or unstable angina (HR, 0.53; 95% CI, 0.40–0.70; P < .00001); and (4) 0.45 and 0.85 for the combined end point of nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes (HR, 0.53; 95% CI, 0.40–0.69; P < .00001). The rates of death from any cause in the rosuvastatin and placebo groups, respectively, were 1.00 and 1.25 per 100 person-years of follow-up; the HR for the rosuvastatin group was 0.80, with a 95% CI of 0.67– 0.97 (P < .02). These effects were consistent in women and all subgroups evaluated including black and Hispanic populations. The rosuvastatin group had a higher incidence of physician-reported diabetes but did not show a significant increase in myopathy or cancer. The findings show that rosuvastatin significantly reduces the incidence of major cardiovascular events in a population of apparently healthy men and women without hyperlipidemia but with elevated levels of high-sensitivity C-reactive protein.
