Prognostic value of preoperative high-sensitivity C-reactive protein to albumin ratio in patients with dilated cardiomyopathy receiving pacemaker therapy: A retrospective two-center study in China.

Background: Despite receiving pacemaker therapy, patients with heart failure with reduced ejection fraction (HFrEF) due to dilated cardiomyopathy (DCM) remain at an increased risk of adverse cardiovascular events. The high-sensitivity C-reactive protein (hs-CRP)-to-albumin ratio (CAR) is a novel indicator. This study aimed to assess the prognostic value of preoperative CAR in this population.
