目的 :探讨青年与老年急性心肌梗塞 (AMI)的临床特点。方法 :对 1 5例青年组 (年龄≤ 40岁 )与 1 4 3例老年组 (年龄≥ 6 5岁 ) AMI的临床资料进行了对比分析。结果 :青年组 AMI吸烟者占 73.3% ,明显高于老年组 (P<0 .0 1 )。老年组 AMI发病率 38.9% ,无心绞痛者占 37.8% ,合并心力衰竭、心源性休克及病死率分别为 2 9.4%、2 2 .4%及 2 7.3% ,均明显高于青年组 (P<0 .0 5 )。结论 :青年组 AMI吸烟者明显高于老年组 ,老年组 AMI发病率、无心绞痛者、合并心力衰竭、心源性休克及死亡率均明显高于青年组
Objective: To investigate the clinical features of acute myocardial infarction (AMI) in young and old. Methods: The clinical data of AMI in 15 youths (≤40 years old) and 143 elderly patients (≥65 years old) were compared. Results: Young smokers accounted for 73.3% of AMI smokers, significantly higher than the elderly group (P <0.01). The incidence of AMI was 38.9% in the elderly group and 37.8% in the non-angina group. The incidence of heart failure, cardiogenic shock and mortality in the elderly group were 29.4%, 22.4% and 27.3% respectively, significantly higher than those in the young group (P <0 .0 5). Conclusion: The AMI smokers in the youth group were significantly higher than those in the elderly group. The incidence of AMI, angina pectoris, heart failure, cardiogenic shock and mortality in the elderly group were significantly higher than those in the youth group
