Blood pressure variability associated with in-hospital and 30-day mortality in heart failure patients: a multicenter cohort study.

ABSTRACT: To investigate the association between blood pressure variability (BPV) and mortality (in-hospital and 30-day) among heart failure (HF) patients, and to examine these associations across patient subgroups. This multicenter retrospective cohort study analyzed 25,591 heart failure patients from two intensive care databases (eICU Collaborative Research Database [eICU-CRD] and the Medical Information Mart for Intensive Care IV [MIMIC-IV]). BPV was assessed using coefficient of variation of systolic (SBPV), diastolic (DBPV), and mean (MBPV) blood pressure measurements. Multivariable logistic regression and Cox proportional hazards models evaluated mortality associations, adjusting for clinical parameters. The observed mortality rates were 14.7% (in-hospital) and 17.3% (30-day). Higher BPV demon
