Coronary Artery Calcium-guided Primary Prevention of Major Coronary Heart Disease in Asymptomatic Diabetes

To evaluate benefits of primary prevention of major coronary heart disease for asymptomatic coronary artery disease in type 2 diabetes mellitus based on the coronary artery calcium score Our proposal 1. Based on CAC score, primary early prevention could reduce incidence of major coronary heart disease (CHD) including cardiac mortality, acute myocardial infarction, coronary revascularization 2. based on CAC score, primary early prevention could reduce all cause mortality, cardiac mortality, cardiovascular disease, heart failure, ischemic stroke, heart failure associated hospitalization and chronic kidney disease and related clinical cost effect
