背景：由左主干冠状动脉（LMCA）病变引起的急性冠状动脉综合征（ACS）是一种危重疾病，但经皮冠状动脉介入治疗（PCI）的住院结果数据有限。方法和结果：日本急性心肌梗死登记是一个全国性的、真实世界的数据库。回顾性收集2011年1月至2013年12月期间住院的13548名ACS患者的临床资料，这些患者来自10个具有代表性的ACS区域登记组。我们将404例（3.0%）LMCA ACS患者与其余13144例非LMCA ACS患者进行比较。LMCA组年龄较大，st段抬高型心肌梗死发生率较低，Killip级晚期发生率较高。LMCA ACS患者的住院死亡率明显高于非LMCA ACS患者(分别为23.3%和5.5%
Background: Acute coronary syndrome (ACS) due to an unprotected left main coronary artery (LMCA) lesion is a critical condition, but there are limited data available on in-hospital outcomes of percutaneous coronary intervention (PCI). Methods and Results: The Japan Acute Myocardial Infarction Registry is a nationwide, real-world database. The clinical data on 13,548 ACS patients hospitalized between January 2011 and December 2013 were retrospectively collected from 10 representative regional ACS registry groups. We compared the 404 patients (3.0%) with LMCA ACS with the remaining 13,144 patients with non-LMCA ACS. The LMCA group was characterized by older age, lower rate of ST-segment elevation myocardial infarction, and higher rate of advanced Killip class. In-hospital mortality was significantly higher in patients with LMCA ACS than in those with non-LMCA ACS (23.3% vs. 5.5%, respectively; P
