A Novel Non-contrast CT Analysis based Method for Segmenting Epicardial Fat and Exploring the Correlation between Epicardial Fat and Cardiac Function

Diabetes is one of the risk factors for metabolic syndrome and leads to an increased risk of cardiovascular events. Epicardial fat is located between the myocardium and the pericardium, directly contacting the coronary arteries, and is therefore closely related to cardiovascular events. We developed a method for segmenting epicardial fat, which achieved a DICE score of 0.6811 on the validation set. Based on this, we explored the correlation between epicardial fat, cardiac structure, and cardiac ejection function in diabetic patients. The results show that epicardial fat first alters the cardiac structure in diabetic patients, subsequently affecting their cardiac ejection function.
