Risk analysis of gastrointestinal bleeding in hospital patients with acute myocardial infarction undergoing primary PCI

摘要

Dual antiplatelet therapy with aspirin and a P2Y12 inhibitor is the cornerstone of acute myocardial infarction(AMI)management,both invasive and conservative.[1,2]This dual strategy improved ischemic outcomes but was offset by an increased bleeding risk.The prognostic importance of bleeding events has been well established over the past decades,as several studies have shown a strong association between bleeding and mortality.[3]The CRUSADE score is superior to other scores in predicting in-hospital major bleeding events.In this regard,in its non-ST elevation acute coronary syndromes(NSTE-ACS)guidelines,the European Society of Cardiology(ESC)stated that the CRUSADE score could be considered for bleeding risk quantification of coronary angiography in NSTE-ACS patients(class IIb,level B evidence).[4]However,the most common site of spontaneous.
