摘要
目的探讨不同剂量瑞舒伐他汀对急性心肌梗死择期介入治疗患者近中期预后的影响。方法 182例急性心肌梗死行择期介入治疗患者,分为常规剂量组(术前、术后及维持瑞舒伐他汀剂量均为10 mg/晚)、术前负荷剂量组(瑞舒伐他汀术前1周给予20 mg/晚,术后持续给予10 mg/晚)、围术期负荷剂量组(瑞舒伐他汀术前1周给予20 mg/晚,术后给予20 mg/晚,连续2周,尔后持续给予10 mg/晚)和持续负荷剂量组(瑞舒伐他汀术前1周给予20 mg/晚,术后持续给予20 mg/晚,至随访时结束)。对患者冠脉介入治疗术前、出院前和术后3个月的临床资料、心肌血清标记物、心脏彩超等资料进行统计学分析。结果各组临床基础资料和病变特征差异无显著性,但3个负荷剂量组术后心肌灌注分级(MBG3)级获得率高于常规剂量组(P<0.05)、校正的TIMI帧数计数(cTFC)、术后肌酸激酶同工酶(CK-MB)、肌钙蛋白I(TnI)和超敏C反应蛋白(hs-CRP)均低于常规剂量组(P<0.05);主要心血管病事件(MACE)发生率各组相似。术后3个月3个负荷剂量组hs-CRP低于常规剂量组(P<0.05),LVEF和LVEDD值显著高于常规剂量组(P<0.05),且围术期负荷剂量组和持续负荷剂量组显著优于术前负荷剂量组(P<0.05)。围术期负荷剂量组和持续负荷剂量组主要心血管病事件较常规剂量组显著减少(P<0.05);术前负荷剂量组虽呈现减少趋势,但无统计学差异。结论急性心肌梗死择期介入治疗患者给予围术期负荷剂量和持续负荷剂量瑞舒伐他汀可通过改善微循环、减轻炎症等减少心肌损伤,从而改善中期心功能,减少心血管事件的发生。
