摘要
目的探讨急诊经皮冠状动脉介入治疗术(PCI)对ST段抬高型急性心肌梗死(STAMI)的治疗价值。方法STAMI46例,在发病12h内行急诊冠状动脉造影及直接冠脉支架置入术(DS)或预扩张后支架置入术(PS),观察术中心律失常发生情况,术后TIMI分级、心电图,出院前左室射血分数(LVEF)和住院期间主要不良心脏事件(MACE)等。结果DS组与PS组各项指标无差异,44例达TIMI3级,成功率达95.7%,ST段回落率67.4%,平均LVEF(49.4±9.46)%,术中心律失常发生率21.7%,无MACE发生。结论对于发病12h的STAMI患者,行急诊PCI,可开通梗塞相关动脉(IRA),改善心肌再灌注和近期预后。
Objective To assess the value of primary percutaneous coronary intervention（PCI） in patients with ST-segment elevated acute myocardial infaction （STAMI）. Methods 46 STAMI patients within 12h after symptom onset received coronary angiography and direct coronary stenting（DS） or conventional postdilatation stenting（PS）.The arrhythmia in the operation, TIMI grade, electrocardiogram, left ventficular ejection fraction （LVEF） and major adverse cardiac events （MACE） were recorded. Results There were no significant difference in all conditions between DS and PS groupes.44 cases got TIMI 3 grade perfusion, the rate were 97.5%. The rate of ST-segment resolution were 67.4%. The mean LVEF （%） were 49.4±9.46. The morbidity of arrhythmia were 21.7%, and no MACE happened. Conclusion For STAMI patients within 12h of symptom onset, primary PCI can open the infarction relative artery（IRA ）, improve myocardial reperfusion and short term prognosis.
