To investigate the effect of hyperglycemia on atherosclerosis and coronary heart disease, we used a mouse model of diet-induced coronary artery atherosclerosis and myocardial infarction, the high fat/high cholesterol (HFC) diet fed SR-B1 knockout (KO)/apoE-hypomorphic (HypoE) mouse. The gene discussed is APOE; the disease is coronary artery disorder.
