Systolic Blood Pressure Time in Target Range and Acute Kidney Injury in Patients With Hypertension.

ABSTRACT:

Background

Acute kidney injury (AKI) is a serious complication of hypertension management. However, the association between systolic blood pressure (SBP) time in target range (TTR) and the risk of AKI remains unclear.

Methods

This is a post hoc analysis of the SPRINT (Systolic Blood Pressure Intervention Trial). Participants were randomly assigned to intensive (<120 mm Hg) or standard (<140 mm Hg) SBP treatment arms. SBP TTR was defined as 110 to 130 mm Hg for the intensive arm and 120 to 140 mm Hg for the standard arm over 3 months. The primary outcome was incident AKI. The secondary outcome was the severity of AKI based on the modified Kidney Disease: Improving Global Outcomes criteria. Competing risk models were used to estimate the relationship between SBP TTR and AKI.
