Abstract

Guidelines recommend using out-of-office blood pressure (BP) measurements to confirm the diagnoses of hypertension and in the titration of antihypertensive medication. The prevalence of out-of-office BP phenotypes for an office systolic/diastolic BP goal <140/90 mm Hg has been reported. However, the prevalence of these phenotypes when targeting an office systolic/diastolic BP goal <120/80 is unknown. The SPRINT (Systolic Blood Pressure Intervention Trial) Ambulatory BP Ancillary study evaluated out-of-office BP using ambulatory BP monitoring in 897 participants 27 months after randomization to intensive versus standard BP targets (office systolic BP <120 versus <140 mm Hg). We used office and daytime BP to assess the proportion of participants with white-coat effect (standard target: office BP ≥140/90 mm Hg and daytime BP <135/85 mm Hg versus intensive target: office BP ≥120/80 mm Hg and daytime BP <120/80 mm Hg) and masked uncontrolled hypertension (standard target: office BP <140/90 mm Hg and daytime BP ≥135/85 mm Hg versus intensive target: office BP <120/80 mm Hg and daytime BP ≥120/80 mm Hg) in each treatment arm. The prevalence of white-coat effect and masked uncontrolled hypertension was 9% and 34%, in both treatment groups. Among participants with uncontrolled office BP, white-coat effect was present in 20% and 23% in the intensive and standard groups, respectively. Among participants with controlled office BP, masked uncontrolled hypertension was present in 62% and 56% in the intensive and standard groups, respectively. In conclusion, a more intensive BP target resulted in a similar proportion of patients with white-coat effect and masked uncontrolled hypertension compared with a standard target.
