Objective To review and study the relationship between the clinical features of aortic dissection patients and their prognosis. Methods Spiral CT with aortic reconstruction and/or transthoracic echocardiography were need for diagnosis. A retrospective analysis of 157 patients with aortic dissection in sex, age, past medical history, admission level of heart rate and systolic blood pressure and prognosis of data were made using Chi square test. Results Patients who had a history of hypertension suffered higher mortality than patients without hypertension history (mortality 15% vs. 7% , P =0. 178). Heart rate ≥90 beats per minute when admitted encountered higher mortality than patients with slower heart rate (mortality 22. 9% vs. 7. 3% ,P =0. 006). Systolic pressure < 100 mm Hg or ≥140 mm Hg had higher mortality than that of normal systolic pressure patients (mortality 40. 0% and 11. 4% vs. 8.5% respectively, P = 0.003). Asymmetrical bilateral upper limb blood pressure were showed higer mortality than that of similar bilateral upper limb blood pressure (mortality 42. 9% vs. 1. 1% , P < 0. 05). The highest mortality was found in male patients of age 41 - 50 years old (28% ). Conclusions Patients with age from 41 to 50 years old, men, heart rate ≥90 beats per minute, systolic pressure < 100 mm Hg or ≥140 mm Hg, and asymmetric blood pressure at admission showed higher mortality rate.%目的 研究主动脉夹层患者临床特征,提高诊治水平.方法 以螺旋CT主动脉重建和/或经胸超声心动图为诊断依据,回顾性分析2004年至2009年4月157例主动脉夹层患者的性别、年龄、既往病史、入院时心率、收缩压水平与预后的关系.结果 既往有高血压诊断史者较无高血压病史者死亡率高(15％比7％),入院时心率≥90次/分较＜90次/分者死亡率高(22.9％比7.3％).入院时收缩压＜ 100 mm Hg或≥140 mm Hg者较正常范围者死亡率高(分别是40.0％、11.4％与8.5％).双侧上肢血压不对称者死亡率较对称者高(42.9％比7.1％)；男性死亡高危年龄为41 ～ 50岁(死亡率28％).结论 男性患者41～50岁、入院时心率≥90次/分、收缩压≥140 mm Hg或＜100 mm Hg、双侧血压不对称,均是死亡的危险因素,差异具有统计学意义.
