Background Positron emission tomography/computed tomography (PET/CT) with 18F-fluorodeoxyglucose (FDG) is widely used in cancer care, but its role in assessing cardiotoxicity remains uncertain. Understanding how cardiovascular risk factors influence myocardial glucose uptake may improve its application in this setting. Objective To investigate associations between cardiac metabolic patterns on oncologic PET/CT and cardiovascular risk factors. Methods We conducted a retrospective, cross-sectional study classifying oncologic PET/CT scans by absence (G1) or presence (G2) of myocardial FDG uptake, visually defined as greater than the aortic blood pool. Clinical data and cardiovascular risk factors were analyzed, and logistic regression identified predictors of presence or absence of uptake, adjusting for potential confounders. Statistical significance was set at p
