目的研究不同年龄组急性心肌梗死(AMI)患者的病理特点及相关因素。方法系统回顾分析55例不同年龄(青年组、壮年组和老年组)AMI的冠状动脉病理及相关因素。结果青年组枷发病前诱因明确,老年组无明确诱因。青年组发病以男性多见,与吸烟、血脂异常危险因素有关。冠状动脉以单发病变多见。壮年组男性多于女性,男性发病与血脂异常,吸烟及高血压危险因素有关,冠状动脉以单支及双支病变多见。老年组女性病人多,除上述危险因素外,糖尿病患者明显增多。冠状动脉病变以多发、复杂病多见。结论青年男性AMI发病增多,并与某种危险因素有关,随年龄增长,冠状动脉多支及复杂病变多见。
Objective To study the pathological features and related factors of patients with acute myocardial infarction (AMI) in different age groups. Methods The coronary artery pathology and related factors of 55 AMI patients of different ages (young group, middle age group and old age group) were retrospectively analyzed. Results Before the onset of flail in the youth group, the incentive was clear. There was no clear incentive for the elderly group. Incidence of young men more common, and smoking, dyslipidemia risk factors. Coronary artery disease more common. Male group was more than female group in males. Male morbidity was related to dyslipidemia, smoking and risk factors of hypertension. Coronary arteries were more common in single and double vessel diseases. Elderly group of female patients, in addition to the above risk factors, significantly increased in patients with diabetes. Coronary artery disease to multiple, complex disease more common. Conclusion The incidence of AMI in young men is increased, and related to some risk factors. With age, multiple coronary arteries and complicated lesions are more common.
