Abstract: Objective To explore the clinical characteristics of orthostatic hypotension(OH) in the elderly patients with hypertension, so as to provide evidence for the patient management. Methods A total of 115 cases of hypertension admitted to Department of Geriatrics,Beijing Tongren hospital were enrolled from September 2023 to May 2024. The supine blood pressure and orthostatic blood pressure of the patients were measured to diagnose OH, and the orthostatic intolerance symptoms were recorded. The general information, comorbidities, medication history and nutrition indicators of the patients were collected and compared. Results The overall prevalence of OH was 31.3% (36/115), and the prevalence of outpatients was 20.0% (8/40), and the prevalence of inpatients was 37.3% (28/75). The proportion of the patients with hypertension combined with orthostatic intolerance symptoms was 13.9%. Compared with the patients without OH, the proportion of cerebrovascular disease,peripheral artery disease, and antidepressant use was higher, and the serum albumin level was lower in the patients with hypertension combined with OH (P<0.05). Conclusions Cerebrovascular disease, peripheral arterial disease, antidepressants use and low level of albumin may be associated with OH in the elderly patients with hypertension.
