目前中国急性ST段抬高型心肌梗死发病率呈上升趋势,且死亡率高,因此对其临床管理显得至关重要.直接经皮冠脉介入术是急性ST段抬高型心肌梗死的首选方案,但直接经皮冠脉介入术时间窗限制在12 h,最多不超过24 h.因此仍有大部分患者错过了直接经皮冠脉介入术的时间窗,临床上对于错过时间窗的急性ST段抬高型心肌梗死患者是否行延迟经皮冠脉介入术或者直接药物保守治疗目前尚未统一.现通过总结与比较错过直接经皮冠脉介入术时间窗患者的不同临床治疗方案,为临床上延迟经皮冠脉介入术在急性ST段抬高型心肌梗死中的应用及应用时间提供依据.“,”At present,the incidence and mortality of acute ST-segment elevation myocardial infarction (STEMI)in China is increasing with high mortality,therefore it is critical to clinical management.Direct percutaneous coronary intervention (PCI)is the preferred option for acute STEMI,but the direct PCI time window is limited to only 12 hours and no more than 24 hours.Consequently,most patients miss the time window of primary PCI.Clinically,whether patients with acute STEMI who missed the time window are undergoing delayed PCI or direct drug-conservative treatment is controversial.This article provides a basis for clinical application of delayed PCI in STEMI and its application time by summarizing and comparing different clinical treatment options for patients who missed the primary PCI time window .
