Objective To study the lifestyle of young and middle - aged acute cerebral infarction ( ACI) patients and the characteristics of carotid artery disease. Methods ①compareel the 87 young and middle - aged ( under 45 ) ACI patients with 81 healthy control groups and made a retrospective analysis of their lifestyle ( including diet, patterns of life, sleep, alcohol consumption, smoking, social and labor nature, mobile phone using time, exercise time, etc. ). ②compared the 87 young and middle -aged (under 45 years old) ACI patients with 95 elderly ACI control groups ( over 55 years old) in terms of the characteristics of carotid artery disease. Results ①Young and middle - aged ACI patients were likely to be overweight, heavy smoker and excessive drinker. They were living an irregular life with high salt and high fat food and less excise. ②Jugular artery ultrasonography showed that young and middle - aged patients had an unstable carotid plaque detection rate of 32. 18% (28/87) and stable carotid plaque detection rate of 21. 84% ( 19/87). They were mainly mild and moderate carotid stenosis. ③the elderly group had an unstable carotid plaque detection rate of 47. 37% (45/95)and stable carotid plaque detection rate of 23. 16% ( 22/95 ). They were mainly moderate and heavy carotid stenosis. Conclusion Unhealthy lifestyles is an important risk factor of cerebral infarction among young and middle - aged people. The main clinical symptoms of carotid artery disease is unstable carotid plaque. Tne carotid stenosis is usually in a mild and moderate degree.%目的 探讨中青年急性脑梗死(ACI)患者的生活方式及其颈动脉病变的特征.方法 ①小于45岁ACI患者87例为中青年组,与81例健康对照组比较,分析他们的生活方式(饮食结构,生活规律,睡眠状况,饮酒,吸烟,社会劳动性质,手机使用时间,运动时间等)；②大于55岁的ACI患者95例为老年对照组,比较中青年ACI组与老年ACI对照组的颈动脉病变的特征.结果 ①中青年ACI患者多体型肥胖,大量吸烟,酗酒,生活无规律,以高盐,高脂注重口味饮食为主及运动量减少等；②颈动脉彩超示,中青年组患者颈动脉不稳定斑块检出率为32.18％ (28/87),稳定斑块检出率21.84％(19/87),颈动脉狭窄主要为轻-中度狭窄；③老年组不稳定斑块检出率为47.37％ (45/95),稳定型斑块检出率为23.16％(22/95),颈动脉狭窄主要为中-重度狭窄.结论 不良生活方式是中青年脑梗死发病的重要危险因素,颈动脉病变以不稳定型斑块为主,颈动脉内径主要表现为轻-中度狭窄.
