Orthostatic Hypotension (OH) in a Population of Hypertensive Patients in the University Hospital Gabriel Touré (UH GT)

Abstract

Objective: This study was intended to determine the prevalence of HO and characteristics of patients who had an OH. Methodology: The study was cross-sectional, conducted in the cardiology department of the UH GT from January to June 2013 in a population of known hypertensive patients aged over 15 years seen as outpatients and who agreed to participate in the study. OH and NonOH were used to name patients with and without OH. OH was looked up to 5 min. The analysis was performed with SPSS software. Results: The overall prevalence of OH was 31.8% Age, SBP, DBP and HR were lower for NonHO patients resp. p = 0.004, <0.0001 <0.0001 and 0.016. The female sex had a low predictive value compared to male (OR 0.594 and p = 0.011). The OR for the occurrence of OH versus the age group > = 60 years were 1.974, 2.616 and 1.692 respectively for ages < 30, 30-44 and 45-59 years (p = 0.004). The OR for the occurrence of OH versus compared to higher education level were 0,411, 0,326 et 0,716 (p=0,049) resp. for unschooled, primary and secondary level. Conclusion: OH is frequent in the hypertensive population with nearly a third of patients. His research must be extended up to 5 minutes.
