CMR in Type 2 Diabetes Mellitus Patients

The study will be performed as a cross-sectional survey. 300 Type 2 diabetes patients (T2DM), with or without known cardiovascular disease, will be recruited from the diabetes outpatient clinic, Slagelse Hospital. The patients will undergo echocardiography, Cardiac magnetic resonance imaging (CMR), clinical examination and will be asked to fill out questionnaires. This study project sets out to answer the following hypotheses: 1. Patients with T2DM have an increased risk of developing diastolic dysfunction. Using CMR, the investigators wish to measure left ventricle peak filling rate and passive atrial emptying fraction as a measure of cardiac diastolic function. The investigators hypothesize that classic T2DM markers such as levels of urinary albumin excretion, retinopathy, autonomic neuropathy, hypertension, dyslipidemia, elevated HgbA1c, T2DM duration, etc. are associated with pathological findings by CMR. 2. Patients with T2DM have impaired left ventricle myocardial perfusion as determined by gadolinium contrast CMR. The investigators hypothesize that the classic markers and risk factors mentioned above, are associated with left ventricle myocardial hypoperfusion as determined by gadolinium contrast CMR.
