Study summary

This study aims to investigate the myocardial phenotype of patients with type 2 diabetes. From 2016-2019 the investigators recruited a cohort of 296 subjects with type 2 diabetes. All subjects underwent clinical examinations including a gadolinium contrast cardiac MRI.

The current study is a clinical follow-up study of the subjects, thus, the investigators will invite all participants to a reevaluation with cardiac MRI.

Additionally, the investigators will aim at recruiting additionally 400 patients with type 2 diabetes.

The aim it to characterize the phenotype of diabetic cardiomyopathy. Uniquely using cardiac MRI we can measure myocardial microvascular function, myocardial localised and diffuse fibrosis in addition to the quantification of myocardial structure and systolic and diastolic function.

Groups and cohorts

  • Patients with type 2 diabetes

    This group will be split up into different groups. DM2 with vs. without complications to diabetes DM2 with vs. without albuminuria/nephropathy or autonomic neuropathy or retinopathy or peripheral neuropathy or macrovascular angiopathy

    Diagnostic Test: All subjects will undergo cardiac magnetic resonance imaging with gadolinium contrast and with adenosine myocardial perfusion

  • sex and age matched control subjects

    Diagnostic Test: All subjects will undergo cardiac magnetic resonance imaging with gadolinium contrast and with adenosine myocardial perfusion

Interventions

  • Diagnostic testAll subjects will undergo cardiac magnetic resonance imaging with gadolinium contrast and with adenosine myocardial perfusion

    This is a observational follow up study accordingly all subjects will undergo the same examinations

    Also known as: Echocardiography, medical interview, general medical examination, BP, HR e.g., Examination for non cardiac complications to diabetes

What researchers measure

Primary outcomes

  1. Association of myocardial microvascular function in patients with type 2 diabetes with MACE after 5 years

    Myocardial microvascular function is measured by the myocardial perfusion ratio, quantified by cardiac MRI. MACE defined as CVD events (AMI, HF, stable angina, atrial fibrillation, ventricular arytmia), stroke, death

    Time frame: 5 years follow-up

  2. Clinical factors associated with worsening of diabetic cardiomyopathy after 5 years

    Clinical factors :Albuminuria, autonomic neuropathy, retinopathy, HbA1c, hs-CRP. Signs of worsening af diabetic cardiomyopathy: Increased myocardial extracellular volume, decreased myocardial blood flow and myocardial perfusion reserve, decreased strain (GLS; GCS, GRS), increasing E/e´, increasing concentri remodeling index(LV mass / LV end-diastolic volume)

    Time frame: 5 years follow-up

  3. Impact of myocardial perfusion and cardiac cardiac output on perfusion in other organs (kidney, spleen, liver) assed by gadolinium contrast magnetic resonance imaging

    Myocardial perfusion measured by myocardial blood flow and myocardial perfusion ratio quantified by cardiac MRI.

    Time frame: Baseline and at 5 years follow-up

  4. The association of pericardial- and epicardial fat with myocardial function and MACE after 5 year

    Myocardial function: LVEF, LV strain (GLS, GCS, GRS), E/e´, myocardial extracellular volume, myocardial perfusion ratio. MACE defined as CVD events (AMI, HF, stable angina, atrial fibrillation, ventricular arytmia), stroke, death

    Time frame: Baseline and at 5 years follow-up

Secondary outcomes

  1. Characterization of the progression of diabetic cardiomyopathy over 5 years, including LV+RV function, the coronary microvascular function, the coronary macrovascular function, fibrosis, aortic stiffness, per and epicardial fat, perfusion of other organs

    Using multivariable regression including age, sex, smoking, Hypertension, HbA1c, CRP, blood pressure, albuminuria, autonomic neuropathy, retinopathy factors associated with either progression or regression of diabetic cardiomyopathy will be tested. Progression of diabetic cardiomyopathy will be defined as increasing myocardial extracellular volume, decreasing myocardial perfusion reserve, decreasing strain (GLS, GCS, GRS), increasing E/e´compared to baseline.

    Time frame: 5 years follow-up
