Older Age is a Risk Factor for Diastolic Orthostatic Hypotension

Objective: This study aimed to investigate the associations orthostatic hypotension (OH) and the cognitive status of patients.Materials and Methods: OH diagnosis was achieved by measuring the supine blood pressure (BP), which was taken twice after lying for 5 min and the standing BP, which was taken twice after standing for 3 min. Mini-mental state examination (MMSE) determined the cognitive status of patients. If the score of MMSE was below 24, then the patient was diagnosed with cognitive impairment.Results: The prevalence of OH, systolic OH (SysOH) and diastolic OH (DiOH) were 31.8% (n=181), 16.7% (n=95), and 24.1% (n=137), respectively. 23.9% of participants had CI. Individuals with older age were at higher risk for OH and DiOH [odds ratio (OR) =1.03, 95% confidence intervals (CI) =1.01-1.05, p=0.012 for OH and OR =1.04, 95% CI =1.01-1.06 p=0.013 for DiOH). In multivariate analysis, OH, SysOH, and DiOH were not related to CI (all p>0.05).Conclusion: The presence of OH increases with aging, so its evaluation should not be forgotten.
