Abstract：Objective To analyze the causes of in-hospital death during direct percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Methods The data were collected from died STEMI patients during PCI from Jan. 2010 to Dec. 2013, and the death causes were retrospectively analyzed. Results There were totally 1314 STEMI patients undergone PCI, among them 44 died during hospitalization and mortality was 3.3%, and average onset-to-hospital time was (5.3±4.6) h. There were 43.8%cases with anterior descending infarction, among them 11 undergone percutaneous transluminal coronary angioplasty. There were 33 cases undergone implantation of 44 stents and average (1.1±0.8) stents implanted in one case. The primary death causes were cardiogenic shock (56.8%), cardiac rupture (20.5%) and vascular complications (15.9%, including non-reflow, stent thrombosis, and coronary artery perforation and dissection). Conclusion The causes of in-hospital death during direct PCI are cardiogenic shock, cardiac rupture and vascular complications in STEMI patients.
