国际多中心的登记资料已经说明,冠状动脉综合征(ACS)的出血事件与死亡有着独立的相关性。然而,在巴西这种相关性还未证实,其出血与死亡的真正原因的关系也没有完全说明。本研究目的在于验证:①主要出血是院内ACS死亡的独立预测因素;②这两种终点的关系是有原因的。本研究收录患者为达到预制标准的不稳定型心绞痛、非ST段抬高心肌梗死或ST段 International multicenter registration data have shown that there is an independent association between deaths and death from coronary artery disease (ACS). However, this correlation in Brazil has not been confirmed, and the relationship between bleeding and the real cause of death is not fully explained. The purpose of this study was to verify that: (1) major bleeding is an independent predictor of hospital-induced death in ACS; (2) there is a reason for the relationship between these two end points. This study included patients with unstable angina pectoris, non-ST-segment elevation myocardial infarction or ST segment
