Angiographic characteristics and in-hospital mortality among patients with ST-segment elevation myocardial infarction presenting without typical chest pain: an analysis of China Acute Myocardial Infarction registry

摘要

Patients with ST-segment elevation myocardial infarction (STEMI) who present without typical chest pain are associated with a poor outcome. However, whether angiographic characteristics are related to a higher risk of mortality in this population is unclear. This study aimed to investigate whether the higher mortality risk in patients with STEMI without chest pain could be explained by their “high-risk” angiographic characteristics.
