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 ACSL1, ALDH2, CYP27A1 and PPARA, demonstrating a good ability for

DCM and myocardial infarction prediction. PPARA 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.
