摘要
目的观察不稳定型心绞痛(UAP)患者经皮冠状动脉介入治疗(PCI)术前不同负荷剂量阿托伐他汀钙对患者预后的影响。方法将UAP患者90例随机分为3组,每组30例。低剂量组:入院后口服阿托伐他汀钙每天20 mg,术前2~4 h口服阿托伐他汀钙20 mg;中剂量组:入院后口服阿托伐他汀钙每天40 mg,术前2~4 h口服阿托伐他汀钙40 mg;高剂量组:入院后口服阿托伐他汀钙每天60 mg,术前2~4 h口服阿托伐他汀钙60 mg。所有患者均在入院后48~72 h内接受PCI,观察各组PCI术前、术后肌酸激酶同工酶、心肌肌钙蛋白I、高敏C反应蛋白的变化及PCI术后30天内主要不良心脏事件的差异。结果高剂量组术后24 h心肌肌钙蛋白I及高敏C反应蛋白显著低于低剂量组(P<0.05)。低剂量组、中剂量组及高剂量组患者与PCI相关的心肌梗死的发生率分别为23%、13%、0%,有显著性差异(P<0.01)。高剂量组主要不良心脏事件发生率显著低于低剂量组(0%比23%,P=0.005)。PCI术后随访30天,3组均无死亡及靶血管血运重建事件发生。结论 UAP患者择期PCI术前短期负荷阿托伐他汀钙每天60 mg可以显著降低与PCI相关的心肌梗死。
