Abstract：Objective To analyze the clinical features and coronary artery lesions of acute ST-segment elevation myocardial infarction (STEMI) at different ages.Methods Totally 496 patients with acute STEMI who underwent emergency percutaneous coronary intervention in Beijing Ditan Hospital,Capital Medical University from May 2016 to August 2018 were enrolled.According to their age,the patients were divided into 4 groups:≤44 years old(group A,66 cases),45-59 years old (group B,215 cases),60-74 years old (group C,147 cases) and ≥ 75 years old (group D,68 cases).Basic clinical data,biochemical indicators and coronary artery lesions were analyzed.Results Male rate,smoking rate and body mass index in group A and B were significantly higher and rate of cerebrovascular disease was lower than those in group C and D;body mass index in group A was significantly higher than that in group C and D;body mass index in group B was significantly higher than that in group D (all P ＜ 0.05).Levels of serum triglyceride,total cholesterol,non-high density lipoprotein cholesterol,apolipoprotein B,serum uric acid and hemoglobin in group A were significantly higher than those in group C and D,and the levels of lipoprotein-a and serum creatinine were significantly lower than those in group D (all P ＜ 0.05).There was no significant difference in culprit vessels among groups (P ＞ 0.05).Rate of single vessel lesion in group A was significantly higher[51.5％(34/66) vs 8.8％ (6/68)] and rate of three vessel lesions was lower[22.7％ (15/66) vs 47.1％ (32/68)] than those in group D(both P ＜0.05).Conclusions Young and middle-aged patients with acute STEMI should recognize the importance of smoking cessation,weight control,close attention on serum triglyceride,uric acid and hemoglobin levels.Elderly patients should comprehensively control blood lipid,blood sugar,blood pressure and blood uric acid.
