Abstract：Objective To explore the clinical features of the patients with acute ST segment elevation myocardial infarction who got a spontaneous reperfusion between middle age and the elderly patients. Methods Sixty -eight acute ST segment elevation myocardial infarction ( STEMI ) patients with spontaneously recanalization in the coronary artery were consecutively enrolled.The patients were divided into two groups based on age, middle age group and elderly age group.The demographic data, clinical baseline data, coronary angiographic findings and hospital survival rate were documented in the two groups.Results Between the two groups, gender composition ratio, chest pain lasting time,“with or without chest pain symptoms”, myocardial infarction site, nitroglycerin containing history, smoking history, aspirin taking history, hyperlipidemia history, hypertension history, statin-taking history, PCI history, whether involving the trunk, in -hospital survival rate, heart failure rate, pre -infarction angina, myocardial infarction complication, cardiogenic shock, coronary occlusion site, “whether to need to vasoactive drugs” were counted and analyzed with no significant difference ( P >0.05 ). However, the middle group had a higher rate of initial coronary heart disease(P<0.05).Conclusion <br> There is no significant difference between middle and elderly patients with STEMI in the demographic data, baseline clinical data, coronary angiography results and hospital survival rate.The middle age group has a higher rate of initial coronary heart disease, which suggests that first time-STEMI in middle age people is prone to spontaneous reperfusion.
