[The beneficial effects of lipid-lowering therapy with xuezhikang on cardiac events and total mortality in coronary heart disease patients with or without hypertension: a random, double-blinded, placebo controlled clinical trial].

Objective: To evaluate whether lipid-lowering therapy with Xuezhikang can reduce the risk of cardiac events and total mortality in coronary heart disease (CHD) patients with or without hypertension.

Methods: In this random, double-blinded, placebo controlled clinical trial, 2704 patients with hypertension and 2166 patients without hypertension were enrolled and capsule Xuezhikang 0.6 g Bid or placebo on the top of conventional therapy without other lipid-lowering drugs. The mean follow-up period was four years. The primary end-points were nonfatal myocardial infarction and total mortality.

Results: Compared to placebo group, the incidence of cardiac events was reduced by 44.0% (P<0.0001) and 47.4% (P<0.0001) respectively in CHD patients with or without hypertension, and the total mortality was lowered by 35.8% (P=0.0012) and 28.6% (P=0.0737) respectively in CHD patients with or without hypertension. There was no significant difference in side effects between study groups.

Conclusion: Xuezhikang can reduce the cardiac events and mortality in CHD patients with or without hypertension.
