    ### Instruction:
    How to diagnose Diabetic Heart Disease ?
    ### Response:
    Your doctor will diagnose diabetic heart disease (DHD) based on your signs and symptoms, medical and family histories, a physical exam, and the results from tests and procedures.
                
Doctors and researchers are still trying to find out whether routine testing for DHD will benefit people who have diabetes but no heart disease symptoms.
