Help us find out by joining our study at UAB by participating in the PRECISION-BP research study investigating the effects of Sacubitril/Valsartan or Valsartan on your body’s 24-hour rhythm of a hormone in your blood called natriuretic peptides. This hormone and the study medications are related to the heart. Eligible participants must be obese (BMI: 30-45 kg/m2) men and women, have high blood pressure, and have no history of heart or kidney problems. The study involves wearing a blood pressure monitor for 24 hours, 24-hour inpatient visits at UAB Hospital, taking medications, and collecting blood and urine samples. Meals will be provided at no cost. Participants will be compensated $575 for completing the study visits.
