Identification of shared fatty acid metabolism related signatures in dilated cardiomyopathy and myocardial infarction.

Aim: It is to be elucidated the risk-predictive role of differentially expressed fatty acid metabolism related genes (DE-FRGs) in dilated cardiomyopathy (DCM) and myocardial infarction.

Materials & Methods: Four gene enrichment analyses defined DE-FRGs' biological functions and pathways. Three strategies were applied to identify risk biomarkers and construct a nomogram. The 4-DE-FRG correlation with immune cell infiltration, drugs, and ceRNA was explored.

Results: DE-FRGs were enriched in lipid metabolism. A risk nomogram was established by  and , demonstrating a good ability for DCM and myocardial infarction prediction. was positively correlated with adaptive immunocytes. Thirty-five drugs are candidate therapeutic targets.

Conclusion: A nomogram and new biological targets for early diagnosis and treatment of DCM and myocardial infarction were provided.
