Another look at the results of the JUPITER trial

Abstract

Justification for the Use of Statins in Prevention: An Intervention Trial Evaluating Rosuvastatin (JUPITER) was a placebo-controlled trial undertaken on "apparently healthy" subjects selected primarily on the basis of high-sensitivity C-reactive protein concentrations >or=2.0 mg/L. JUPITER showed that rosuvastatin reduced the incidence of cardiac events compared to a control group. The study population (median age 66 years) included men and women with the metabolic syndrome (about 41%), median blood pressures in the prehypertensive range, current smoking (about 15%), median body mass indexes higher than normal, and Framingham 10-year risk >10% (about 50%). The presence of these risk factors indicates that a significant proportion of subjects were not "healthy" and warranted aggressive management under current guidelines, without the measurement of high-sensitivity C-reactive protein. Furthermore, <17% of the trial participants were taking guidelines-recommended aspirin, and 25% had systolic blood pressures >145 mm Hg and would have merited treatment for hypertension. It is likely that many of the participants did not receive care consistent with current standards. Thus, the benefit of statin therapy would have been more difficult to demonstrate if standard therapeutic recommendations had been followed. In conclusion, these considerations cast doubt on the contention that statin therapy should be initiated in apparently healthy individuals on the basis of elevated high-sensitivity C-reactive protein levels.
