Objective- To evaluate the efficacy of intensive lipid lowering with higher-dose statins. Methods- Meta-analysis of seven randomized controlled trials comprising 50,972 participants. Results- Mean follow-up was 3.1years with mean age 63years. Final LDL-C levels in intensive lipid-lowering group were 1.42-2.07mmol/l compared to 2.1-3.5mmol/l in the less intensive or control group. The intensive arm had significantly lower risks for stroke OR 0.80 (95% CI 0.71-0.89); major coronary events OR 0.74 (95% CI 0.65-0.83); cardiovascular disease (CVD) or coronary heart disease (CHD) deaths OR 0.84 (95% CI 0.74-0.95). Significantly higher liver enzyme abnormalities occurred in intensive group * (OR 3.96; 95% CI 2.08-7.53), but it was not associated with drug discontinuations (OR 1.20; 95% CI 0.88-1.64). Conclusion- In those at high risk of cardiovascular events, intensive lipid lowering with statins to LDL-C level <2.1mmol/l significantly reduces risk of stroke, major coronary events and CVD or CHD deaths compared to LDL-C level ≥2.1mmol/l.
