A retrospective analysis of systolic blood pressure time in target range among patients in coronary care unit.

ABSTRACT: The research aimed to illustrate the prognostic value of systolic blood pressure time in target range (SBP-TTR) calculated by continuously monitoring blood pressure (BP) records among patients admitted to coronary care units. Data from the Medical Information Mart for Intensive Care-IV database was used in this retrospective cohort study. Systolic blood pressure (SBP) target ranges were defined as 110-140 mmHg for awake time, and 90-120 mmHg for sleep time, respectively. SBP-TTR was calculated as the proportion of measured SBP in the target range among all SBP measurements, and participants were divided into four groups according to the categories of TTR. We used Cox proportional hazard regression models to assess the association between SBP-TTR and one-year all-cause mortality. A total of
