title: Blood Pressure Control Provides Less Cardiovascular Protection in Adults With Than Without Apparent Treatment-Resistant Hypertension.
abstract: Hypertension control may offer less protection from incident cardiovascular disease (CVDi ) in adults with than without apparent treatment-resistant hypertension (aTRH), ie, blood pressure uncontrolled while taking three or more antihypertensive medications or controlled to <140/<90 mm Hg while taking four or more antihypertensive medications. Electronic health data were matched to health claims for 2006-2012. Patients with CVDi in 2006-2007 or with untreated hypertension were excluded, leaving 118,356 treated hypertensives, including 40,690 with aTRH, and 460,599 observation years. Blood pressure and medication number were determined by all clinic visit means from 2008 to CVDi or end of study. Primary outcome was first CVDi (stroke, coronary heart disease, heart failure) from hospital and emergency department claims. Controlling for age, race, sex, diabetes, chronic kidney disease, and statin use, hypertension control afforded less CVDi protection in patients with aTRH (hazard ratio, 0.87; 95% confidence interval, 0.82-0.93) than without aTRH (hazard ratio, 0.69; 95% confidence interval, 0.65-0.74; P<.001). Strategies beyond hypertension control may prevent more CVDi in patients with aTRH.
