>50岁男性腹主动脉超声筛查的意义及影响因素

Significance and influencing factors of ultrasonographic screening of abdominal aorta in men over 50 years old

目的探讨在住院患者中开展>50岁男性腹主动脉超声筛查的意义及影响因素。方法回顾性分析2018年3月至2019年6月广东省人民医院内分泌科和心内科50岁以上男性住院患者的相关临床资料和腹主动脉超声结果。将腹主动脉直径>30 mm作为腹主动脉瘤组,通过单因素和多因素Logistic回归分析寻找腹主动脉瘤的独立危险因素和保护因素。结果本研究最终入选2827例,腹主动脉瘤筛查阳性率为1.7%(48例),腹主动脉直径为(37.1±7.5)mm;对照组2779例(98.3%),腹主动脉直径为(18.5±2.9)mm。年龄≥70岁、估算肾小球滤过率(eGFR)<45 mL-1·min^-1·1.73 m^-2和原发性高血压(高血压)是腹主动脉瘤筛查阳性的独立危险因素,糖尿病是腹主动脉瘤筛查阳性的保护因素。结论在住院患者中,针对50岁以上男性开展腹主动脉超声筛查是可行的,特别是在年龄>70岁、合并高血压或慢性肾脏病患者中筛查阳性率更高。

Objectives To explore the positive rate and influencing factors of ultrasonic screening of abdominal aorta in men over 50 years old.Methods The clinical data and abdominal aortic ultrasound results of male patients over 50 years old in the Department of Endocrinology and the Department of Cardiology in Guangdong Provincial People's Hospital from March 2018 to June 2019 were analyzed retrospectively.The diameter of abdominal aorta larger than 30 mm was in abdominal aortic aneurysm group,and the independent risk factors and protective factors of abdominal aortic aneurysm were found by univariate and multivariate Logistic regression analysis.Results A total of 2827 cases were screened in this study with the positive rate of abdominal aortic aneurysm was 1.7%(48 cases),and the diameter of abdominal aorta was(37.1±7.5)mm,while that of the control group was 2779 cases(98.3%)with diameter of abdominal aorta was(18.5±2.9)mm.Age≥70 years old,estimated glomerular filtration rate(eGFR)<45 mL-1·min^-1·1.73 m^-2 and hypertension were independent risk factors for abdominal aortic aneurysms,while diabetes was protective factor for abdominal aortic aneurysms.Conclusions It is feasible to carry out abdominal aortic ultrasound screening for men over 50 years old,especially in patients over 70 years old,complicated with hypertension or chronic kidney disease.
