    ### Instruction:
    What are the symptoms of Diabetic Heart Disease ?
    ### Response:
    Some people who have diabetic heart disease (DHD) may have no signs or symptoms of heart disease. This is called silent heart disease. Diabetes-related nerve damage that blunts heart pain may explain why symptoms aren't noticed.
                
Thus, people who have diabetes should have regular medical checkups.
