According to NHANES data, the prevalence of hypertension increases dramatically with age. While 28.6% of Americans have hypertension, the incidence increases to 66.7% in those ages 60 and older. The prevalence of resistant hypertension (i.e., uncontrolled blood pressure with three anti-hypertensive medications, controlled BP with ≥4 anti-hypertensive medications) is rising at a faster rate than hypertension itself.
