Hypertension is prevalent in the United States and remains uncontrolled. The primary objective of the study was to determine the effect of once-daily dosing of a combination therapy for blood pressure (BP) and dyslipidemia using home BP monitoring on reaching clinical BP and the effect of daily dosing of combination therapy on reaching lipid goals. The study was conducted in middle-aged, indigent, African Americans who had high-risk, resistant hypertension and dyslipidemia. Patients were randomly assigned to either the home and clinic BP group or usual care group and were followed for 6months. The average BPs for each group were compared and used to titrate the study drug appropriately. Both groups achieved significant declines in BP, total cholesterol, and low-density lipoprotein (LDL) (P<.0001). These findings demonstrate that BP control could be achieved at a rate of 43.5% compared with the 2004 national control rate of 35%. The LDL control rate was also improved. Cardiovascular risk reduction has been proven to be achieved through managing lipids and BP. This trial demonstrates that these goals can be achieved similar to other groups in indigent African Americans with high-risk hypertension and dyslipidemia.
