Cardiac Mortality-Risk Assessment Improved by Evaluation of Hemoglobin Level in Combination with Kidney Function in the Patients with Systolic Heart Failure: A Cohort Study

Abstract

Background: Anemia and chronic kidney disease have been shown to be determinants of the prediction of poor prognosis in heart failure (HF) patients, but there is little information on their relationship with cardiac events. We examined prognostic interactions among kidney dysfunction, hemoglobin (Hb) level and other clinical variables in chronic HF patients.
