The fibrinogen-to-albumin ratio (FAR) indicates inflammation and is linked to worse outcomes in acute heart failure (AHF). However, low FAR predicts poorer survival in patients with low albumin levels.
Area of Science:
- Cardiology
- Biomarkers
- Acute Heart Failure
Background:
- The fibrinogen-to-albumin ratio (FAR) is an emerging biomarker.
- Its role in acute heart failure (AHF) requires further investigation.
Purpose of the Study:
- To evaluate the association between FAR and clinical characteristics in AHF patients.
- To assess the prognostic value of FAR for mortality and heart failure events in AHF.
Main Methods:
- Analysis of 1,402 hospitalized AHF patients.
- Calculation of FAR (plasma fibrinogen/serum albumin × 1,000).
- Multivariate logistic regression and Cox proportional hazards models were used.
Main Results:
- High FAR was associated with inflammation (C-reactive protein), ischemic heart disease, and diabetes mellitus.
- Elevated FAR predicted poorer 730-day all-cause mortality in the overall AHF cohort.
- Low FAR was an independent predictor of increased 730-day mortality and heart failure events specifically in the low-albumin subgroup.
Conclusions:
- FAR is associated with inflammation and comorbidities in AHF.
- High FAR indicates adverse prognosis in the general AHF population.
- Low FAR signifies poor prognosis in AHF patients with low serum albumin.

The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
