An additional 10% glucose administration to the high-dose liraglutide group ameliorated cardiac dilation and fibrosis. a An image representing the cardiac long axis view. b Heart/body weight which indicates severity of heart failure, was clearly decreased in HF-H-G group. c Sirius red staining showed improved cardiac fibrosis by 10% glucose treatment in combination with high-dose liraglutide (n = 4). Representative images of anterior wall in short axis of the heart are shown (scale bar: 500 µm). *p > 0.05 vs. HF + high-dose liraglutide group. HF heart failure, HF-H-G heart failure + 10% glucose
