ABSTRACT
Objective: To explore the prevalence and risk factors of orthostatic hypotension (OH) in elderly hypertension patients. Methods: A total of 532 retired hypertension patients elder than 65 years in Guangzhou military region were enrolled. The patients were divided into 2 groups: Hypertension group, n=414 and Hypertension combining OH (H+OH) group, n=118. The patient's age (65-79、≥ 80), hypertension grade (Grade 1-3) and complication status were studied. The risk factors for H+OH prevalence were analyzed by multivariate Logistic regression analysis. Results: The incidence rate of H+OH was 22.2％ (118/532). In H+OH group, the ratios of elderly and very elderly patients were 6.7％ and 23.1％, P<0.05 and the ratios of OH occurrence for hypertension grade 1, 2 and 3 were 12.6％, 23.3％ and 25.2％ respectively, P<0.05. Multivariate Logistic regression analysis presented that systolic blood pressure (BP) in supine position, BP at immediate standing, heart rate in supine position, heart rate after 2 minutes standing and chronic cardiac insufficiency were the impact factors for H+OH occurrence, P<0.05. Conclusion: In elderly hypertension patients, incidence of OH was increasing with age elevating; H+OH has been related to age, severity of hypertension and chronic cardiac insufficiency.
