摘要 目的:探讨对急性ST段抬高型心肌梗死(STEMI)患者直接经皮冠状动脉腔内介入治疗(PCI)术前使用负荷剂量阿托伐他汀80mg对缺血心肌的保护作用及机制。方法:选择2009年12月至2010年12月在我院心内科CCU住院诊断为STEMI的患者162例,随机分为阿托伐他汀组(80例)和对照组(82例),阿托伐他汀组直接PCI术前给予80mg阿托伐他汀,对照组术前则不给予任何剂量的他汀类药物。观察两组患者术后心肌灌注指标:术后2hST段回落(STR);校正TIMI帧计数(CTFC),肌酸激酶同工酶(CK-MB)峰值以及术前、术后内皮细胞功能指标一氧化氮(NO)、内皮素-1(ET-1),纤溶活性指标组织型纤溶酶原激活物(t-PA)及纤溶酶原激活物抑制物-1(PAI-1)的变化。结果:阿托伐他汀组患者术后心肌灌注水平、血管内皮细胞功能和纤溶活性的指标均优于对照组,CK-MB峰值低于对照组,术后1周患者左室射血分数(LVEF)高于对照组。结论:STEMI患者直接PCI术前使用负荷剂量他汀能改善术后患者的心肌灌注水平,保护缺血心肌,其机制与改善血管内皮功能及纤溶活性相关。
