Systolic Blood Pressure Intervention Trial (SPRINT)

SPRINT will randomize about 9250 participants aged ≥ 50 years with SBP ≥130 mm Hg and at least one additional CVD risk factor. The trial will compare the effects of randomization to a treatment program of an intensive SBP goal with randomization to a treatment program of a standard goal. Target SBP goals are <120 vs <140 mm Hg, respectively, to create a minimum mean difference of 10 mm Hg between the two randomized groups. The primary hypothesis is that CVD event rates will be lower in the intensive arm. Participants will be recruited at approximately 90 clinics within 5 clinical center networks (CCNs) over approximately a 2-year period, and will be followed for 4-6 years.
