Objectives. The aim of this prospective cohort, multicentre study was to assess the effect of coadministrating ezetimibe 10 mg/day with an ongoing statin on the estimated risk for Cardiovascular (CVD) mortality in patients with persistently elevated LDL-C after statin monotherapy. Methods. The Systematic Coronary Risk Evaluation (SCORE) function was used to estimate the 10-year risk for cardiovascular mortality at baseline and 6 weeks. Primary outcome measures were absolute and percent changes in estimated Coronary Heart Disease (CHD) Mortality Risk, and general CVD Mortality Risk (Total CVD Mortality Risk). Results. 825 patients were included in the analysis. Mean (SD) age was 62 (10.5) years and 62.3% were males. The mean (SD) estimated Total CVD Mortality Risk decreased from 0.068 (0.059) at baseline to 0.053 (0.046) at 6 weeks (RR = 0.77; 95% CI:0.689-0.867), while the estimated CHD Mortality Risk decreased from 0.047 (0.040) at baseline to 0.034 (0.029) at 6 weeks (RR = 0.72; 95% CI:0.624-0.826). Conclusions. Co-administration of ezetimibe with a statin is effective in significantly reducing the estimated risk for cardiovascular mortality as measured by the SCORE model.
目的。这项前瞻性队列多中心研究的目的是评估每天服用10毫克依折麦布并联合正在使用的他汀类药物对他汀类药物单药治疗后低密度脂蛋白胆固醇(LDL-C)持续升高的患者心血管疾病(CVD)死亡估计风险的影响。方法。采用系统性冠心病风险评估(SCORE)函数来估计基线和6周时心血管疾病死亡的10年风险。主要结局指标为估计的冠心病(CHD)死亡风险和一般心血管疾病死亡风险(总心血管疾病死亡风险)的绝对变化和百分比变化。结果。825名患者纳入分析。平均(标准差)年龄为62(10.5)岁,男性占62.3%。估计的总心血管疾病死亡风险均值(标准差)从基线时的0.068(0.059)降至6周时的0.053(0.046)(相对风险=0.77;95%置信区间:0.689 - 0.867),而估计的冠心病死亡风险从基线时的0.047(0.040)降至6周时的0.034(0.029)(相对风险=0.72;95%置信区间:0.624 - 0.826)。结论。依折麦布与他汀类药物联合使用可有效显著降低通过SCORE模型测量的心血管疾病死亡估计风险。
