Prognosis influence factors of percutaneous coronary intervention for patients with ST elevation myocardial infarction

Abstract

Objective To investigate the prognosis influence factors of percutaneous coronary intervention（ PCI）for ST segment elevation myocardial infarction（ STEMI）factors,and provide theoretical basis for improving the prognosis and quality of life. Methods The data of 182 STEMI patients treated by PCI in the people’s hospital of Jincheng from September 2007 to April 2010 were divided into nondeath group（n=105）and death group（n=77）according to their survival state. The clinical characters were retrospectively analyzed,and characteristics of statistical difference were into multiple Logistic regression analysis. Results The single factor analysis showed that there were significant differences in the clinical features including age,the first symptom and the reperfusion time,gender,diabetes mellitus, history of myocardial infarction,cardiac function in Killip ’s classification,degree of vascular lesions and drug use（P﹤0. 05）;Multiple regression analysis showed that older age,symptoms begin,to reperfusion time longer,diabetes,vascular lesions≥2 and without the use of beta blockers,ACEI or ARB were independent prognostic factors of PCI in the treatment of STEMI（ P ﹤0. 05 ）. Conclusions Older age, symptoms begin,to reperfusion time longer,diabetes,vascular lesions ≥2 and without the use of beta blockers,all the above factors will lead to poor outcome in patients with STEMI,therefore,after admission the patient should take all measures to shorten the symptom onset to reperfusion time,and actively correct high blood glucose,improve heart function and the use of vasodilators,in order to improve the prognosis of patients,ensure the quality of life.
