Resistant Hypertension and Associated Comorbidities in a Veterans Affairs Population

Resistant hypertension ( RH ) is understudied and its reported prevalence varies with study populations. The authors sought to determine its prevalence and association with certain comorbid conditions in a Veterans Affairs population. This cross‐sectional study utilized demographic and clinical data from 17,466 patients. Chi‐square or t test was used for comparing groups with and without RH . Multivariate logistic regression analysis was used to determine independent associations. Overall, the prevalence of RH was 9%, and 13% of all hypertensive patients met criteria for RH. After adjusting for confounding variables, RH was significantly associated with older age (odds ratio [ OR], 1.007), higher body mass index ( OR, 1.04), Framingham score ( OR, 1.14), and coexisting coronary artery disease , cerebrovascular accident / transient ischemic attack , peripheral vascular disease , congestive heart failure , chronic kidney disease , diabetes mellitus , erectile dysfunction, and metabolic syndrome ( OR, 1.3, 1.32, 1.29, 2.88, 2.13, 1.2, 1.12, and 1.2, respectively; all P <.05). Our results indicate a complex interplay of certain comorbid conditions among patients with RH and suggest the need for multifaceted interventions in this high‐risk population to prevent cardiovascular events.
