Elevation in systolic blood pressure during heart failure hospitalization is associated with increased short and long-term mortality.

Covariates that were highly significant in a univariate model were introduced in a multivariate model using the best subset method: age, gender, New York Heart Association (NYHA) class >II, anemia (defined as hemoglobin <11 g/dL), admission SBP as a continuous variable, estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m 2 using the MDRD formula, HFpSF (vs HFrSF), and admission heart rate as a continuous variable.
