Evaluating the Serum Sodium to Log(D-dimer) Ratio as a Predictor of Overall Mortality in Chronic Heart Failure Patients with Varying Ejection Fractions
To evaluate the impact of log-SDR on clinical outcomes in heart failure patients with different ejection fractions, specifically assessing its prognostic value.
Approach:
Study Population: Retrospective analysis of 1,221 medical records from patients diagnosed with acute exacerbations of chronic heart failure (AECHF) at the First Affiliated Hospital of Kunming Medical University.
Data Collection: Collected demographic information, medical history, clinical data, and laboratory parameters from electronic medical records, focusing on serum sodium and D-dimer levels.
Statistical Analysis: Used Kaplan–Meier curves for survival analysis and Cox regression models to identify predictors of all-cause mortality.
Key Findings:
Log-SDR was calculated as serum sodium divided by log-transformed D-dimer.
Patients were stratified into low and high log-SDR groups based on an optimal cut-off value of 47.90.
The study included 1,008 patients after applying exclusion criteria.
Interpretation:
The log-SDR may serve as a prognostic marker in chronic heart failure, reflecting the interplay between sodium levels and coagulation status.
Limitations:
Retrospective design may introduce bias.
Exclusion of patients with certain comorbidities limits generalizability.
Conclusion:
The study indicates that further research is needed to determine the prognostic utility of log-SDR in assessing mortality risk in chronic heart failure patients.
Moderate coffee consumption generally appeared safe for most adults, but randomized evidence suggested divergent effects on atrial fibrillation and premature ventricular contractions.
