To evaluate the efficacy of intensive lipid lowering with higher-dose statins.
Meta-analysis of seven randomized controlled trials comprising 50,972 participants.
Mean follow-up was 3.1 years with mean age 63 years. Final LDL-C levels in intensive lipid-lowering group were 1.42-2.07 mmol/l compared to 2.1-3.5 mmol/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).
In those at high risk of cardiovascular events, intensive lipid lowering with statins to LDL-C level <2.1 mmol/l significantly reduces risk of stroke, major coronary events and CVD or CHD deaths compared to LDL-C level ≥ 2.1 mmol/l.

The phrase, "Significantly higher liver enzyme abnormalities occurred in less intensive group", was amended to "Significantly higher liver enzyme abnormalities occurred in intensive group".].
评估高剂量他汀类药物强化降脂的疗效。
对包含 50972 名参与者的 7 项随机对照试验进行荟萃分析。
平均随访 3.1 年,平均年龄 63 岁。强化降脂组的最终 LDL-C 水平为 1.42-2.07mmol/L,而低强度降脂组或对照组的 LDL-C 水平为 2.1-3.5mmol/L。强化降脂组发生卒中的风险显著降低(OR 0.80,95%CI 0.71-0.89);主要冠状动脉事件(OR 0.74,95%CI 0.65-0.83);心血管疾病(CVD)或冠心病(CHD)死亡(OR 0.84,95%CI 0.74-0.95)的风险显著降低。强化降脂组肝酶异常发生率显著升高(OR 3.96,95%CI 2.08-7.53),但与药物停药无关(OR 1.20,95%CI 0.88-1.64)。
对于心血管事件高危人群,将他汀类药物降低 LDL-C 水平至<2.1mmol/L 的强化降脂治疗与 LDL-C 水平≥2.1mmol/L 相比,可显著降低卒中、主要冠状动脉事件和 CVD 或 CHD 死亡的风险。[*2011 年 1 月 11 日更正:在 2010 年 10 月 27 日首次在线发表后。短语“低强度降脂组肝酶异常发生率更高”被修正为“强化降脂组肝酶异常发生率更高”。]
