Abstract: Objective  To analyze current situation and related factors of percutaneous coronary intervention (PCI) in patients with nonST segment elevated acute coronary syndrome(NSTEACS). Methods  475 NSTEACS patients in our hospital were enrolled from 2008 to 2015. The clinical data  included gender， age， smoking， drinking， hypertension， diabetes mellitus， stroke， chronic kidney disease， chronic myocardial infarction， and level of blood sugar， blood fat， creatinine， myocardial biomarkers， and the status of coronary angiography and interventional therapy. Comparison was made in the clinical information between PCI group and non PCI group， the association factors of PCI in multiple logistic regression mode were analyzed. Results  Compared to nonPCI group (n=105)，PCI group (n=109) had higher percentage of male(67.0% vs 51.4%，P<0.01)， NSTEMI (32.1% vs 9.5%，P<0.01) and heart function class Ⅱ (50.9% vs 30.4%，P<0.01)，and higher fasting bloodglucose (6.5±2.6 vs 5.8±1.9  mmol/L，P=0.02). The percentage of cardiovascular risk factors， and serum creatinine， triglycerides level were not different significantly between two groups. The male， heart function grade Ⅱ，and NSTEMI were influence factors of PCI in the multiple logistic regression mode. Conclusion  The rate of coronary intervention in NSTEACS patients was 22.9% in our hospital，the male， function grade，and MI are influence factors of PCI.
