[目的]探讨老年、中青年冠心病(CHD)患者的冠状动脉病变特点及危险因素的不同。[方法]将145例CHD患者根据年龄分为中青年组(年龄<50岁)和老年组(年龄≥65岁),观察其性别、吸烟、高血压、糖尿病、血脂等冠心病危险因素的区别,比较两组冠状动脉病变差异。[结果]两组患者均以男性为主,且男性患者较女性冠状动脉病变程度为重,中青年组以单支病变为主,而老年组以多支病变较多,差异有显著性(P<0.05)。老年组CHD患者高血压、糖尿病为主要危险因素,高血脂症为中青年组主要危险因素。[结论]中青年冠心痛患者,以男性为主,对其早期防治有重要的意义。
[Objective] To investigate the characteristics of coronary lesions and risk factors in elderly patients, young and middle-aged patients with coronary heart disease (CHD). [Methods] 145 CHD patients were divided into middle-aged group (aged <50 years) and elderly group (aged ≥65 years) according to their age, and their differences in risk factors of CHD such as gender, smoking, hypertension, diabetes mellitus, The differences of coronary artery lesions between the two groups were compared. [Results] The patients in both groups were predominately male, and the prevalence of coronary lesions was heavier in males than in females. The single-vessel lesion was predominant in middle-aged and young adults, while the multi-vessel lesion was more frequent in elderly patients (P <0.05). Hypertension and diabetes mellitus were the main risk factors in elderly patients with CHD, and hyperlipidemia was the major risk factor in middle-aged and young patients. [Conclusion] The middle-aged and young patients with crown-crown pain are predominantly male, which is of great importance to their early prevention and treatment.
