Justification for the Use of Statins in Prevention: An Intervention Trial Evaluating Rosuvastatin - JUPITER


Statins are currently recommended for primary prevention of cardiovascular disease in high-risk patients. The JUPITER trial was designed to assess whether apparently healthy persons with levels of low-density lipoprotein (LDL) that do not mandate statin treatment, as per current guidelines (<130 mg/dl), but with levels of high-sensitivity C-reactive protein (hs-CRP) ≥2 mg/L, would benefit from taking rosuvastatin.

Contribution to the Literature: The JUPITER trial showed that rosuvastatin was associated with a reduction in cardiovascular events, compared with placebo, in healthy patients with LDL <130 mg/dl, but hs-CRP ≥2 mg/L.

Principal Findings:

A total of 17,802 patients were randomized, 8,901 to rosuvastatin, and 8,901 to placebo. Baseline characteristics were fairly similar between the two groups. About 41% of the patients had metabolic syndrome. Baseline hs-CRP levels were similar between the two arms (median of about 4.3 mg/L). Median LDL, high-density lipoprotein (HDL), triglyceride, and glucose levels were 108, 49, 118, and 94 mg/dl, respectively.

The study was terminated early, after a median of 1.9 years of follow-up (planned maximum follow-up was 5 years). Rosuvastatin was associated with a significant reduction in the incidence of the primary endpoint of nonfatal myocardial infarction (MI), nonfatal stroke, unstable angina, arterial revascularization, or cardiovascular death, compared with placebo (0.77 vs. 1.36 events per 100 person-years [PY] of follow-up, hazard ratio [HR] 0.56; 95% confidence interval [CI] 0.46-0.69, p < 0.00001). This translated into a number needed to treat with rosuvastatin of 95 patients for 2 years, and 31 patients for 4 years.

Among individual participants, there was large variability in the percent reduction of LDL achieved. Among those who did not have a reduction in LDL, the association for rosuvastatin vs. placebo was HR 0.86, for those who achieved <50% reduction in LDL (HR 0.61), and for those who achieved ≥50% reduction in LDL (HR 0.41; p for trend < 0.00001).

There was also a significant reduction in the incidence of individual endpoints: nonfatal MI (0.12 vs. 0.33 events per 100 PY, HR 0.35, 95% CI 0.22-0.58, p < 0.00001), nonfatal stroke (0.16 vs. 0.31 events per 100 PY, HR 0.52, 95% CI 0.33-0.80, p = 0.003), arterial revascularization (0.38 vs. 0.71 events per 100 PY, HR 0.54, 95% CI 0.41-0.72, p < 0.0001), as well as all-cause mortality (1.0 vs. 1.25 events per 100 PY, HR 0.80, 95% CI 0.67-0.97, p = 0.02). Various subgroup analyses were done, including based on gender, race, body mass index, and Framingham risk score, which all yielded consistent results for the primary outcome.

At 4 years, rosuvastatin was associated with a significant reduction in the levels of hs-CRP (median: 1.8 vs. 3.3 mg/L, p < 0.0001), LDL (median: 55 vs. 109 mg/dl), triglycerides (99 vs. 118 mg/dl, p < 0.0001), but not HDL (50 vs. 50 mg/dl, p = 0.34).

The overall incidence of serious adverse effects was similar between the two groups (15.2% vs. 15.5%, p = 0.60), including myopathy (0.1% vs. 0.1%, p = 0.82), rhabdomyolysis (0.01% vs. 0%, p > 0.05), incident cancer (3.4% vs. 3.5%, p = 0.51), cancer deaths (0.4% vs. 0.7%, p = 0.02), hemorrhagic stroke (0.07% vs. 0.10%, p = 0.44), for rosuvastatin vs. placebo, respectively. The incidence of alanine aminotransferase (ALT) >3 x upper limit of normal was similar between the two groups (0.3% vs. 0.2%, p = 0.34). There was a higher incidence of physician-reported diabetes in the rosuvastatin arm (3.0% vs. 2.4%, p = 0.01), as well as higher median glycated hemoglobin at 2 years with rosuvastatin (5.9% vs. 5.8%, p = 0.001); the median fasting glucose at 2 years was similar between the two arms (98 vs. 98 mg/dl, p = 0.12).

Among participants with at least one risk factor for diabetes, the use of rosuvastatin was associated with a 39% reduction in the primary outcome despite a 28% increase in incident diabetes. Among participants with no risk factors for diabetes, the use of rosuvastatin was associated with a 52% reduction in the primary outcome, with no increase in incident diabetes.

Incident fractures were 1.20 per 100 PY versus 1.14 per 100 PY (p = 0.53), respectively, for rosuvastatin vs. placebo.


The results of the JUPITER trial indicate that rosuvastatin is associated with a significant reduction in major cardiovascular events, including death, in apparently healthy persons with LDL cholesterol <130 mg/dl, but hs-CRP ≥2 mg/L. Individuals who had the greatest percent reduction in LDL (not the absolute LDL level), experienced the greatest reduction in adverse events with rosuvastatin. Among those at risk for diabetes, rosuvastatin versus placebo was associated with an increased risk for developing diabetes. Rosuvastatin did not reduce the risk for fractures.

Some of the issues that need further clarification include the long-term safety, efficacy, and cost-effectiveness of utilizing statins in asymptomatic, apparently healthy patients, as well as whether these findings can be considered as a class effect of statins, or as specific to rosuvastatin, which exhibits several pharmacokinetic differences from other statins. It is also not entirely clear whether the observed benefit in this trial is from LDL cholesterol lowering, hs-CRP lowering, or both.

Further, there are some conflicting data regarding a direct correlation between elevated levels of hs-CRP and cardiovascular risk. A recent study found no relationship between genetic polymorphisms resulting in high hs-CRP levels and cardiovascular risk. Inclusion of patients with levels of hs-CRP <2.0 mg/L and a comparison of their risk with the rosuvastatin arm in this trial may have helped answer this question. Although rosuvastatin was associated with an increase in incident diabetes among at-risk individuals, there was still net benefit (reduction in adverse events) from statin therapy.
