INTRODUCTION: Orthostatic hypotension (OH) is a risk factor for morbidity and mortality and one of the causes of non compliance to treatment among medicated hypertensive subjects. Our objective was to assess the prevalence of OH among treated hypertensive patients and its association with clinical characteristics and antihypertensive drug class.
METHODS: This was a cross-sectional study in which we assessed the prevalence of OH, defined according to the American Autonomic Society and American Academy of Neurology guidelines, among adult treated hypertensive patients who performed a home blood pressure monitoring at our institution. We also determined the prevalence of OH according to age group (< 65, 65-79 and > 80), antihypertensive drug class, office and home hypertension control status.
RESULTS: We included 302 medicated patients in the study. Mean age was 66.6 (+13.8), 67% were women. We found a 9.7% global prevalence of OH, which was significantly higher among older individuals (3.6% among patients < 65 years-old, 12.2% in the 65-79 year-old group and 16.7% among octogenarians, p = 0.02) and those who consumed alpha-blockers (75 vs. 8.5%, p < 0.01). Uncontrolled hypertensive patients at office and/or at home had also a significantly higher prevalence of OH: uncontrolled vs. controlled office blood pressure (BP), 14.3 vs. 6.5%, p = 0.03 and uncontrolled vs. controlled home BP, 15.1 vs. 6.6%, p = 0.02. Remarkably, 64% of patients with OH had their BP under control when considering office-standing BP.
CONCLUSION: OH is a prevalent entity among treated hypertensive patients and systematic measurement of standing BP should be mandatory in the evaluation of these patients.
