Standard blood pressure control metrics may not account for fluctuations in blood pressure over time.

This study sought to estimate the independent association between time in systolic blood pressure target range and major adverse cardiovascular events among adults with hypertension.

This study was a post hoc analysis of SPRINT (Systolic Blood Pressure Intervention Trial), a randomized clinical trial that compared intensive (<120 mm Hg) and standard (<140 mm Hg) systolic blood pressure treatment interventions in adults with hypertension and high cardiovascular risk. Target range was defined as 110 to 130 mm Hg and 120 to 140 mm Hg for the intensive and standard arms, respectively. Time in target range was estimated over the first 3 months of follow-up using linear interpolation. The association between time in target range with major adverse cardiovascular events …
