餐后低血压危险因素的临床研究

The risk factors of postprandial hypotension

目的:了解不同年龄段住院患者餐后低血压(PPH)的发病情况及临床特点,探讨PPH的危险因素。方法:随机抽取2015年1-6月在我院住院的430例患者,利用24h动态血压监测仪检测患者3餐前后的血压。结果:住院患者PPH患病率为52.09%。早、中、晚餐PPH的患病率分别为38.14%、19.10%、12.56%,PPH最常发生于早餐后(P<0.05)。<50岁、50~59岁、60~69岁、70~79岁、≥80岁患者PPH的患病率分别为33.30%、37.00%、57.50%、69.40%、71.40%,年龄越大,PPH患病率越高(P<0.05),但Logistic回归分析提示,年龄不是PPH的危险因素,高血压、吸烟与PPH呈正相关性。结论:PPH在住院患者中很常见,不仅好发于老年人,成年人也可发生。早餐后PPH最常见。吸烟、高血压是PPH的危险因素。

Objective：To investigate the incidence and clinical characteristics of postprandial hypotension（PPH）in hospitalized patients in different age groups,and to explore the risk factors of postprandial hypotension.Method：A total of 430 patients were enrolled in our hospital from January to June in 2015.The blood pressure was measured before and after three meals using 24 hambulatory blood pressure monitor.Result：The prevalence rate of PPH in hospitalized patients was 52.09% overall.The prevalence rates of PPH after breakfast（38.14%）was significant higher than after lunch（19.10%）and supper（12.56%）（P〈0.05）.The prevalence rates were different in different age groups,and the older the age,the higher the prevalence of PPH（P〈0.05）,but the binary Logistic regression analysis showed that age was not risk factor of PPH,while hypertension and smoking were positively related to PPH.Conclusion：PPH is common in hospitalized patients,not only in aged,but also in adults.Smoking and hypertension are the risk factors of PPH,most of which happened after breakfast.
