Abstract
Purpose of Review
Resistant hypertension (R-HTN) is related to worse cardiovascular, renal outcomes, and death compared to non R-HTN. We aimed to review the burden of R-HTN across the world, focusing on its prevalence, associated factors and outcomes, and the impact of treatment.
Recent Findings
R-HTN prevalence among hypertensive individuals varies around 10–20%, depending on the population and definition applied. R-HTN consistently relates to older age, chronic kidney disease, obesity, and obstructive sleep apnea – which are increasing in prevalence with global population aging. As such, R-HTN prevalence is also expected to rise. Infrequent use of ambulatory blood pressure monitoring to identify at higher risk individuals and poor adherence to treatment are still barriers in the approach of R-HTN.
Summary
Available evidence suggests that 10–20% of patients with hypertension have R-HTN. However, the prevalence of true R-HTN using contemporaneous standardized definitions is still unknown. Novel strategies to address clinicians, patients and health system barriers to treatment inertia and adherence are fundamental to reduce the burden of R-HTN.

This study uses data from two RCTs and demonstrates not only that R-HTN is associated with important cardiovascular outcomes such as myocardial infarction, stroke, heart failure and cardiovascular death, but also shows data to suggest that the current AHA definitions of R-HTN reduces the association of this condition with cardiovascular outcomes.

J Hypertens. 2019;37(11):2216–24. This study gives us perspectives about the poor translation from evidence to clinical practice regarding treatment of R-HTN. Patients are expected to be using at least 4 drugs (since BP is not controlled with three) and, in choosing the fourth drug, there is clear guideline recommendation of using an aldosterone antagonist. Data from tertiary centers shows us significant underuse of spironolactone, contrasting with the frequent use of beta-blockers, a less effective drug class for HTN.
