  Purpose

The purpose of this study is to investigate the prevalence of cardiac disease/coronary artery disease and diagnostic yield of different non-invasive methods in patients with type 2 diabetes 40-75 years of age at examination. Exercise tests, Doppler echocardiographic examination with Tissue Velocity Imaging, stress Echocardiography, transthoracic Doppler of coronary arteries with coronary flow reserve, and cardiac MRI with late enhancement at rest, and perfusion after vasodilatation stress will be used in the study. A subpopulation will in addition measure forearm vasodilation(FMD) and CFR before and after 4 months of exercise training.

Primary Outcome Measures:
  • Prevalence of cardiac abnormalities/disease according to different examination modalities [ Time Frame: at primary examination ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Feasibility of transthoracic coronary Doppler examination/Coronary Flow Reserve, and diagnostic yield related to MRI. [ Time Frame: at baseline ] [ Designated as safety issue: No ]
    Descriptive study; that is at baseline examination except substudy training group which will also be examined after 4 months of exercise training

  • Relationship between CFR in LAD and forearm FMD [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Relationship between CFR in LAD and forearm FMD before and after 4 months of exercise training in diabetics. Substudy

  • Doppler echocardiographic findings related to clinical, laboratory and MRI findings [ Time Frame: at baseline ] [ Designated as safety issue: No ]
    Special emphasis on new modalities as strain/strain rate at rest and stress. At baseline examination (no follow up)

  • Feasibility of transthoracic coronary Doppler examination/Coronary Flow Reserve, and diagnostic yield related to MRI [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    in exercise training group


Biospecimen Retention:   Samples Without DNA

Routine laboratory tests, parameters to caracterize diabetes controle, inflammatory markers.
