The aim of this study was to explore the impact of low DBP on clinical outcomes in patients with ST-elevation myocardial infarction(STEMI)undergoing percutaneous coronary intervention(PCI). Methods A total of 1232 patients with STEMI were retrospectively enrolled and divided into two groups according to admission DBP level:≥70 mm Hg(n=817)and < 70 mm Hg(n=415). The relationship between DBP and in-hospital and 1-year adverse events was evaluated.Results In-hospital death occurred in 2.4% of patients. The in-hospital mortality(5.3% vs. 1.0%,P<0.001)and major adverse clinical events(11.1% vs. 7.5%,P=0.033)were significantly higher in patients with a low DBP.DBP <70 mm Hg was associated with in-hospital death(adjusted odds rate=3.31,95%CI:1.36-8.07,P=0.009).Additional significant indicators included eGFR < 60 mL/min/1.73 m^2 and intra aorta balloon pump(IABP)treatment. Seventy-seven(6.3%)patients died in the one-year follow-up. DBP < 70 mm Hg was associated with increased risk of 1-year death(8.9% vs. 4.8%,Log-rank=9.9,P=0.002). Conclusion Low DBP was associated with increased risk of in-hospital and 1-year adverse prognosis in patients with STEMI undergoing PCI,which could be a tool for risk assessment.展开更多
