住院主动脉夹层患者血压波动性现状及影响因素研究

Study on the variability of blood pressure in inpatients with aortic dissection and influencing factors

目的了解住院主动脉夹层患者血压波动性现状,并探讨其影响因素。方法收集2019年1月—2020年6月在武汉市某三级甲等医院心脏大血管外科住院并行手术治疗的346例主动脉夹层患者的临床资料,对影响其血压波动性的相关因素进行多元线性回归分析。结果住院主动脉夹层患者收缩压波动为(11.65±3.60)mmHg(1 mmHg=0.133 kPa),舒张压波动为(8.03±1.98)mmHg;性别、年龄、高血压史、吸烟史、饮酒史、入院首诊血压(包括入院首诊收缩压和舒张压)、降压药的种类为血压波动性的主要影响因素(P<0.05)。结论主动脉夹层患者住院期间血压存在一定程度波动,建议医护人员在控制患者血压的同时减少血压的波动,以降低患者病情恶化及死亡风险,改善其预后。

Objective To investigate the variability of blood pressure in hospitalized patients with aortic dissection and explore its influencing factors.Methods We collected the data of 346 patients with aortic dissection admitted to a tertiary first-class hospital in Wuhan city from January 2019 to June 2020.The related factors that may affect the variability of blood pressure were analyzed by multiple linear regression.Results The variability of systolic blood pressure in inpatients with aortic dissection was(11.65±3.60)mmHg(1 mmHg=0.133 kPa),the varia-bility of diastolic blood pressure was(8.03±1.98)mmHg.Gender,age,history of hypertension,smoking history,alcohol drinking history,first admission blood pressure and types of antihypertensive drugs were the main influencing factors of blood pressure variability(P<0.05).Conclusion Blood pressure in patients with aortic dissection fluctuated to a certain extent during hospitalization.It is suggested that medical staff should reduce the fluctuation of blood pressure while controlling the blood pressure of patients,so as to reduce the risk of deterioration and death,and improve the prognosis of patients.
