ABSTRACT
BACKGROUND: Resistant hypertension is associated with adverse cardiovascular outcomes and mortality. In the past decade, management guidelines have shifted to target lower blood pressures (BP). Current prevalence and prescribing patterns among adults with resistant hypertension are not well characterized.
METHODS: We used data from the National Health and Nutrition Examination Survey from 2003 to 2020. Apparent treatment-resistant hypertension (aTRH) was defined as patients on a diuretic, either with a systolic BP ≥130 or diastolic BP ≥80 mm Hg while on 3 medications or those on ≥4 medications regardless of BP. Medications were identified through pill bottle review.
RESULTS: Of 24 579 adults with hypertension, 1939 had aTRH (42.4% male, 19.9% Black), corresponding to a weighted total of 6 989 821 US patients. Among hypertensive adults, the prevalence of aTRH was 6.41% (95% CI, 5.97%-6.88%) and remained stable over time. Over the study duration, aTRH prevalence among adults on treatment decreased from 17.7% to 12.6%. The overall prevalence of hypertension rose from 50.1% to 54.0%, while the prevalence of uncontrolled BP decreased from 75.0% to 68.7%. Over time, use of 3 drug regimens for aTRH decreased (57.8%-42.9%), while 4 drug regimens increased (34.0%-51.8%). aTRH was most strongly associated with older patients, those of Black race, higher body mass index, and more advanced cardiovascular comorbidities.
CONCLUSION: The prevalence of aTRH has remained stable over the past 2 decades despite the rising incidence of hypertension. Use of multidrug treatment regimens has increased, aligning with national guidelines. However, uncontrolled hypertension remains high.
