BACKGROUND: Older hypertensive adults under treatment are especially susceptible to hypotensive episodes, which entail an elevated risk. However, data on this subject are very scarce. AIM: The purpose of this study was to determine the prevalence and predictors of office and home hypotension in older (≥ 65 years) treated hypertensive adults. METHODS: Blood pressure (BP) was measured at the office and at home, using a validated oscillometric device. Office and home hypotension were defined as systolic BP (SBP) < 110 and/or diastolic BP (DBP) < 70 mmHg, and SBP < 105 and/or DBP < 65 mmHg, respectively. Masked hypotension was considered when office BP ≥ 110/70 and home BP < 105 and/or < 65 mmHg. We evaluated factors associated with hypotension both at the office and at home through multivariable models. RESULTS: The prevalence of hypotension among the 302 patients included in the study was 29.8% at the office and 23.9% at home, whereas the prevalence of masked hypotension was 10.4%. Older age, lower body mass index and use of calcium channel blockers were associated with office hypotension, while older age, diabetes and ischemic heart disease were predictors for home hypotension. CONCLUSION: Hypotension is frequent in older hypertensive adults under treatment. The presence of diabetes, ischemic heart disease and older age should alert for screening of hypotension at home to avoid overtreatment.
