Abstract：Objective To retrospect and summarize the curative effect of percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS).Methods ACS patients (n=543) were chosen from Oct. 2003 to Oct. 2013, and then divided into emergency PCI group (n=236) and selective PCI group (n=307). Emergency PCI group was divided again into elderly group 1 (aged≥60,n=124) and non-elderly group 1 (aged from 42 to 59, n=112), and selective PCI group was divided again into elderly group 2 (aged≥60,n=137) and non-elderly group 2 (aged from 42 to 59,n=170). The clinical data were collected from all patients including puncture success rate, PCI success rate, PCI total time, complications after PCI, and major adverse cardiovascular events (MACE) after 1-year follow-up.Results Between elderly group 1 and non-elderly group 1, the percentages of sex, medical history and smoking, locations of myocardial infarction (MI), culprit vessels, blood fat and LVEF had no statistical difference (allP>0.05). The percentages of patients with diabetes and hypertension increased and total cholesterol (TC) level decreased in elderly group 1 compared with non-elderly group 1 (allP<0.05). Between elderly group 2 and non-elderly group 2, the percentages of sex and medical history, locations of MI, culprit vessels, blood fat and LVEF had no statistical difference (allP>0.05). The percentages of patients with diabetes, hypertension and smoking cases increased in elderly group 2 compared with non-elderly group 2 (allP<0.05). The comparison in puncture success rate, PCI success rate, PCI total time, contrast agent dosage, re-revascularization during hospitalization, and re-MI and revascularization procedure during 1-year follow-up had no statistical difference between elderly group 1 and non-elderly group 1 or between elderly group 2 and non-elderly group 2 (allP>0.05). The percentage of died cases, and mortality and heart failure during 1-year follow-up had statistical difference between elderly group 1 and non-elderly group 1 (allP<0.05).Conclusion PCI is an effective therapy for ACS, but its influence on long-term prognosis in elderly patients with ACS needs further discussion.
