不同剂量阿托伐他汀对急性冠脉综合征患者介入治疗围术期疗效及安全性的观察

目的:探讨国人急性冠脉综合征(ACS)患者经皮冠脉介入(PCI)治疗围术期40 mg阿托伐他汀强化治疗的疗效及安全性.方法:采用随机对照研究方法,100例ACS患者随机分为A、B两组.A组50例给予阿托伐他汀20 mg/d,B组50例给予阿托伐他汀40 mg/d.于PCI 术前、术后24 h测定肌钙蛋白I(cTnI);PCI术前、术后5 d、术后30 d测定肌酸激酶(CK)、丙氨酸氨基转移酶(ALT)、低密度脂蛋白胆固醇(LDL-C)、总胆固醇(TC).观察ACS患者随访1个月期间主要心血管事件的发生情况.结果:(1)两组PCI术后24 h cTnI均显著升高(P ＜ 0.01),A组较B组升高幅度差异有统计学意义(P ＜ 0.05).(2)两组在用药后5 d及30 d LDL-C和TC均显著下降(P ＜ 0.01),40 mg组下降幅度更加显著且30 d LDL-C达标率(即LDL-C≤1.8 mmol/L比例)更高(24% vs 66%,P ＜ 0.01).(3)A组30 d主要心血管事件(心力衰竭2例)较A组(再发心肌梗死1例、心力衰竭5例、再发心绞痛需住院治疗3例共9例)显著降低(P ＜ 0.05).(4)两组药物副作用差异无显著性(P ＞ 0.05).结论:ACS患者PCI围手术期阿托伐他汀40 mg/d能显著降低LDL-C、TC、cTnI水平,提高30 d LDL-C达标率,降低围手术期主要心血管事件发生率.

Efficacy and safety of different doses of atorvastatin in ACS patients with PCI preoperative

Objective To study the efficacy and safety of different doses of atorvastatin on lowering intensive lipid in acute coronary syndrome(ACS) patients with percutaneous coronary intervention(PCI) during the preoperative period. Methods A randomized control study was used:100 patients with ACS were selected randomly divided into two groups. 20 mg group,50 patients were given doses of atorvastatin 20 mg/d. 40 mg group,50 patients were given doses of atorvastatin 40 mg/d. Treatment time lasted for 1 month from bef...
