Objective To study the effect of simvastatin on early left ventricular remodeling in acute myocardial infarction (AMI) patients after emergency percutaneous coronary intervention (PCI). Methods Two hundred and forty-five AMI patients undergoing emergency PCI were randomly divided into simvastatin treatment group(n=123) and control group(n= 122). Their TIMI grade,corrected TIMI frame count(cTFC) and myocardial blush grade wen: compared immediately after PCI. Indexes of left ventricular shape and geometry were measured by color Doppler echo-cardiography at <24 h and weekends 1,2 and 3, respectively. Results The LVESD and left ventricular Ra/D at weekend 1.the LVEDD,LVESD,left ventricular Ra/D,left ventricular ASL and PSL at weekends 2 and 3 were significantly higher than their baseline parameters in control group (P<0. 05,P<0. 01). The LVEDD, LVESD, left ventricular ASL and PSL at weekend 2 were significantly lower while the LVEDD, LVESD, left ventricular ASL and PSL, and LVEF at weekend 3 were significantly higher in simvastatin treatment group(P<0. 05,P<0. 01). The LVEDD, LVESD,left ventricular Ra/D, left ventricular ASL and PSL were significantly lower while the LVEF was significantly higher at weekends 2 and 3 in simvastatin treatment group than in control group(P<0. 05). Conclusion Simvastatin can inhibit LVR in AMI patients after emergency PCI.%目的 探讨急性心肌梗死(acute myocardial infarction,AMI)急诊直接PCI术后使用辛伐他汀对早期左心室重构的影响.方法 选择AMI接受急诊直接PCI患者245例,随机分为辛伐他汀治疗组(治疗组)123例和对照组1 22例.比较2组术后即刻TIMI分级、计算校正TIMI计帧数(cTFC)和心肌Blush分级.采用彩色多普勒超声心动仪分别于发病早期(<24 h)、1、2、3周末连续测量、计算左心室形态、构型等指标并进行分析.结果 与基线比较,对照组1周末左心室收缩末内径(LVESD)、左心室短轴前半径(Ra)/内径(D)明显升高,2周末左心室舒张末内径(LVEDD)、LVESD、Ra/D、左心室前部心内膜弧长(ASL)、后部心内膜弧长(PSL)明显升高,3周末LVEDD、LVESD、Ra/D、ASL、PSL、LVEF明显升高,差异有统计学意义(P<0.05,P<0.01);治疗组2周末LVEDD、LVESD、PSL、LVEF明显升高,3周末LVEDD、LVESD、ASL、PSL、LVEF明显升高(P<0.05,P<0.01).与对照组比较,治疗组2周末、3周末LVEDD、LVESD、Ra/D、ASL、PSL明显降低,LVEF明显升高,差异有统计学意义(P<0.05).结论 AMI患者急诊直接PCI术后,使用辛伐他汀对早期左心室重构有抑制作用.
