Analysis Of Risk Factors For Hospital Cardiovascular Events In Patients With Acute Myocardial Infarction After Emergency PCI

Objective:To investigate the risk factors of cardiovascular events in patients with acute myocardial infarction undergoing emergency interventional therapy.Methods:This study is a retrospective study.Between January 2016 and June 2018,141 patients were admitted to the Chest pain center of the First Affiliated Hospital of Shanxi Medical University,who met the diagnostic criteria of acute myocardial infarction(AMI).The patients were treated with emergency percutaneous coronary artery intervention(PCI)within 24 hours after myocardial infarction.The age was(58.06±11.34)years old,including 16 females and 125 males.They were classified according to whether cardiovascular events were occurred during hospitalization as the event group(32 cases)and non-event group(109 cases).Their baseline data were collected,analyzed and compared.Multivariate logistic regression was used to analyze the risk factors of in-hospital cardiovascular events in patients with AMI after emergency PCI.The fitness of the regression model was evaluated by HL statistic(Hosmer-Lemeshow).Results:(1)The incidence of cardiovascular events in the hospital was 22.70%(32/141),with the highest incidence of new heart failure,accounting for 12.77%(18/141);(2)There were no significant differences in gender,heart rate on admission,history of hypertension,history of diabetes,family history of coronary heart disease,history of smoking,white blood cell count(WBC),blood glucose,fibrinogen(FIB),cardiac troponin I(cTnI)peak,total cholesterol(TC),triglycerides(TG),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),uric acid,creatinine,infarction sites,infarct-related vessels,and number of coronary artery lesions and stents implanted between the event group and the non-event group(P>0.05).The difference of age,platelet to lymphocyte ratio(PLR),Killip classification and left ventricular ejection fraction(LVEF)between event group and non-event group was statistically significant(P<0.05);(3)Multivariate logistic regression analysis found there is a clear correlation between age(OR 1.067,95%CI 1.022-1.114),Killip ? II(OR 6.464,95%CI2.543-16.430)and in-hospital cardiovascular events.Conclusion:(1)Heart failure is the most common in-hospital cardiovascular event in patients with AMI undergoing emergency PCI;(2)Age and Killip ? II were risk factors of in-hospital cardiovascular events in patients with AMI after emergency PCI.
