    Abstract: BACKGROUND: The prognosis of high or markedly low diastolic blood pressure (DBP) with normalized on-treatment systolic blood pressure on major adverse cardiovascular events (MACEs) is uncertain. This study examined whether treated isolated diastolic hypertension (IDH) and treated isolated low DBP (ILDBP) were associated with MACEs in patients with hypertension. METHODS AND RESULTS: A total of 7582 patients with on-treatment systolic blood pressure <130 mm Hg from SPRINT (Systolic Blood Pressure Intervention Trial) were categorized on the basis of average DBP: <60 mm Hg (n=1031; treated ILDBP), 60 to 79 mm Hg (n=5432), ≥80 mm Hg (n=1119; treated IDH). MACE risk was estimated using Cox proportional-hazards models. Among the SPRINT participants, median age was 67.0 years and 64.9% were men. Over a median follow-up of 3.4 years, 512 patients developed a MACE. The incidence of MACEs was 3.9 cases per 100 person-years for treated ILDBP, 1.9 cases for DBP 60 to 79 mm Hg, and 1.8 cases for treated IDH. Comparing with DBP 60 to 79 mm Hg, treated ILDBP was associated with an 1.32-fold MACE risk (hazard ratio [HR], 1.32, 95% CI, 1.05-1.66), whereas treated IDH was not (HR, 1.18 [95% CI, 0.87-1.59]). There was no effect modification by age, sex, atherosclerotic cardiovascular disease risk, or cardiovascular disease history (all P values for interaction >0.05). CONCLUSIONS: In this secondary analysis of SPRINT, among treated patients with normalized systolic blood pressure, excessively low DBP was associated with an increased MACE risk, while treated IDH was not. Further research is required for treated ILDBP management.
