%X OBJECTIVE: The study was carried out to evaluate the role of the AST (Aspartate transaminase)/ALT (Alanine transaminase) ratio as an indicator of the functional severity in people with chronic heart failure (CHF) with reduced left ventricular ejection fraction.
METHODS: A prospective cross-sectional study was conducted in a tertiary care centre in South India among the individuals who had left ventricular ejection fraction (LVEF) of ≤40 %. The study period was between January 2021 and December 2021. Consecutive patients with the criteria were enrolled in the study. Study participants were grouped based on their AST/ALT ratio value (ratio<1 and ratio≥1).
RESULTS: In present study of 100 participants, there was a statistically significant difference between two groups with respect to ALT, AST/ALT ratio, and ALP (Alkaline phosphatase). There was a significant correlation between the APRI (AST to platelet ratio index) and FIB-4 (Fibrosis-4) with AST/ALT ratio. Diagnostic analysis of AST/ALT ratio to predict the severity of CHF with reduced EF, the area under the curve (AUC) was 0.547 (p-value = 0.5654) with a 95 % confidence interval of 0.299-0.795 with an optimal cut-off value of 0.6, sensitivity of 96.70 %, and specificity of 33.33 %.
CONCLUSIONS: The AST/ALT ratio is increased in patients with CHF patients with reduced left ventricular ejection fraction. It is a simple predictor of left ventricular dysfunction in patients with heart failure with reduced ejection fraction.
