Representative case of use of the CGMS. The patient was an 86-year-old man who was diagnosed with anterior STE-ACS. He had IGT on a 75-g oral glucose tolerance test during hospitalization. His conventional glucose indicators showed admission hyperglycemia and HbA1c 5.4%. The CGMS can visualize GV. The MAGE is calculated by measuring the arithmetic mean of the difference between consecutive peaks and nadirs (red arrows) if the difference is > 1 SD of the mean glucose. The CGMS revealed that the MAGE was 74 mg/dl. He died after being hospitalized for heart failure 9 months later
