Trial characteristics_1 Confirmatory
Trial characteristics_2 Explanatory
Developmental phase Phase IV

Assessment
Primary outcomes 1) Left ventricular mass and diastolic function by echocardiography (LVMI, E/A, DT, E/e')
2) Blood biomarker of heart failure (BNP, NT-proBNP)
Key secondary outcomes 1) Left ventricular mass by cardiac MRI
2) Electrocardiogram (assessment of autonomic function by R-R variation)
3) Exploratory analysis
To search a patient group in which metformin is useful by carrying out a stratified analysis of patient background male/female, extent and duration of diabetes mellitus, BMI, etc)
