Various cardiac diseases, including myocardial infarction, hypertrophic cardiomyopathy, dilated cardiomyopathy, myocarditis, hypertensive heart disease, and other common conditions.
Conditions
Interventions
Gold Standard:Professional radiologists manually delineate the endocardium and epicardium based on cardiac magnetic resonance imaging to measure cardiac functional parameters and combine clinical data
Index test:The left ventricular function parameters and prediction results derived from the model are compared and analyzed against manual measurements and diagnostic outcomes. The evaluation metrics
