目的研究分析青年人心肌梗死的临床与冠状动脉造影的特点。方法收集34例40岁以下心肌梗死患者,并收集同期住院的55例60岁以上老年心肌梗死患者,所有患者均发病4周内行冠状动脉造影检查,将他们的临床与冠状动脉造影检查结果资料进行对比分析。结果青年组急性心肌梗死患者多与吸烟、高甘油三脂有关,发作多有明确诱因,如大量饮酒,超负荷运动等。冠状动脉病变以单支病变为主,老年组急性心肌梗死患者比青年组具有更多的危险因素,老年组发病前多有心绞痛发作史,冠状动脉病变以双支、多支病变多见。结论青年人急性心肌梗死有它特有的临床特点及冠脉病变特点,其高危性应引起临床重视。
Objective To analyze the characteristics of clinical and coronary angiography in young patients with myocardial infarction. Methods Thirty-four patients under 40 years of age with myocardial infarction were collected and 55 patients aged 60 years or older with myocardial infarction were enrolled in the same period. All patients underwent coronary angiography within 4 weeks of onset and their clinical and coronary angiographic findings were performed Comparative analysis. Results Most of the patients with acute myocardial infarction in youth group were related to smoking and high triglyceride. There were many clear inducing factors such as heavy drinking, overload exercise and so on. Coronary artery lesions were mainly single-vessel disease. Elderly patients with acute myocardial infarction had more risk factors than the young group. The older group had more episodes of angina pectoris before onset and coronary artery disease was more common in patients with double-vessel and multiple-vessel disease. Conclusions Young patients with acute myocardial infarction have its own unique clinical features and characteristics of coronary lesions, its high risk should cause clinical attention.
