Association between hemoglobin-to-creatinine ratio and all-cause mortality in patients with coronary artery disease.

ABSTRACT:

Background

Although the hemoglobin-to-creatinine ratio (HCR) has been recognized as a predictor for various diseases, its prognostic value in patients with coronary artery disease (CAD) remains unclear. This study aimed to examine the association between HCR and all-cause mortality in general CAD patients using data from the National Health and Nutrition Examination Survey (NHANES) database.

Methods

A total of 3701 adult patients with CAD, which was identified through self-report in questionnaires, were included and followed for a mean of 79 months. The association between HCR and all-cause mortality was evaluated using smooth curve fitting, threshold effect analysis, and a competing risk regression model.

Results

A nonlinear association was observed between HCR and a
