Reduction in C-reactive protein and LDL cholesterol and cardiovascular event rates after initiation of rosuvastatin: a prospective study of the JUPITER trial

BACKGROUND: Statins lower high-sensitivity C-reactive protein (hsCRP) and cholesterol concentrations, and hypothesis generating analyses suggest that clinical outcomes improve in patients given statins who achieve hsCRP concentrations less than 2 mg/L in addition to LDL cholesterol less than 1.8 mmol/L (<70 mg/dL). However, the benefit of lowering both LDL cholesterol and hsCRP after the start of statin therapy is controversial. We prospectively tested this hypothesis. METHODS: In an analysis of 15 548 initially healthy men and women participating in the JUPITER trial (87% of full cohort), we prospectively assessed the effects of rosuvastatin 20 mg versus placebo on rates of non-fatal myocardial infarction, non-fatal stroke, admission for unstable angina, arterial revascularisation, or cardiovascular death (prespecified endpoints) during a maximum follow-up of 5 years (median 1.9 years), according to on-treatment concentrations of LDL cholesterol (>/=1.8 mmol/L or <1.8 mmol/L) and hsCRP (>/=2 mg/L or <2 mg/L). We included all events occurring after randomisation. This trial is registered with ClinicalTrials.gov, number NCT00239681. FINDINGS: Compared with placebo, participants allocated to rosuvastatin who achieved LDL cholesterol less than 1.8 mmol/L had a 55% reduction in vascular events (event rate 1.11 vs 0.51 per 100 person-years; hazard ratio [HR] 0.45, 95% CI 0.34-0.60, p<0.0001), and those achieving hsCRP less than 2 mg/L a 62% reduction (event rate 0.42 per 100 person-years; HR 0.38, 95% CI 0.26-0.56, p<0.0001). Although LDL cholesterol and hsCRP reductions were only weakly correlated in individual patients (r values <0.15), we recorded a 65% reduction in vascular events in participants allocated to rosuvastatin who achieved both LDL cholesterol less than 1.8 mmol/L and hsCRP less than 2 mg/L (event rate 0.38 per 100 person-years; adjusted HR 0.35, 95% CI 0.23-0.54), versus a 33% reduction in those who achieved one or neither target (event rate 0.74 per 100 person-years; HR 0.67, 95% CI 0.52-0.87) (p across treatment groups <0.0001). In participants who achieved LDL cholesterol less than 1.8 mmol/L and hsCRP less than 1 mg/L, we noted a 79% reduction (event rate 0.24 per 100 person-years; HR 0.21, 95% CI 0.09-0.52). Achieved hsCRP concentrations were predictive of event rates irrespective of the lipid endpoint used, including the apolipoprotein B to apolipoprotein AI ratio. INTERPRETATION: For people choosing to start pharmacological prophylaxis, reduction in both LDL cholesterol and hsCRP are indicators of successful treatment with rosuvastatin.
