年轻人急性心肌梗死的临床分析

目的　分析年轻人急性心肌梗死 (AMI)的危险因素、临床特征、冠状动脉造影结果以及近期预后。方法　选择年龄≤ 4 0岁的年轻心梗患者 5 7例 ,并与随机选择的同期年龄≥ 6 0岁老年心梗患者 6 0例进行回顾性对照分析。结果　年轻心梗患者吸烟发生率明显高于老年对照组 (6 6 .6 7%与2 8 33% ,P <0 0 0 5 ) ,而糖尿病发生率非常低 (1.75 % ) ,显著低于对照组 (2 5 .0 % ,P <0 .0 0 5 )。年轻人心梗以单支血管病变为主 ,明显高于老年对照组患者 (74 .5 1%与 4 0 .0 % ,P <0 .0 0 5 ) ,住院期间严重心脏事件发生率较低 (8.77%与 2 0 % ,p <0 .0 5 )。结论　年轻人心梗以动脉粥样硬化为主 ,多为单支病变 ,吸烟是最重要的危险因素 ,预后较佳

Clinical analysis of myocardial iafarction in young adults

Objective To analyze the risk factors, clinical characters,the results of coronary angiography (CAG) and recent prognosis of young patients with acute myocardial infarction (AMI).Methods 57 patients, less then 40 years old. compared with those AMI patients over 60 years old (n=60) admitted during the same time.Results Smoking was the most common risk factor in young patient, had significantly greater occurence than in old ones (66.67% vs 28.33%. P<0.005). While diabetes mellitus is less common in young AMI patients than in old patients (1.75% vs 25.25%,P<0.005). Most of the young patients had one-vessel disease, higher than old patients (74.5% vs 40.0%,P<0.005). Young patients had lower severe adverse events than old ones during the hospital (8.77% vs 20%,p<0.05).Conclusion Altherosclerotic coronary anery disease was responsible for most young patients with AMI. Most of them had single -ressel disease. Smoking was the highly common risk factor. The prognosis is well in young patients.
