Study summary

Background: The study of factors associated with diabetic heart disease (DHD), the leading cause of mortality in diabetes, represents an unmet need. Autoimmune diabetes in adults (AID) and type 2 diabetes (T2D) differ in pathophysiology, vascular complications, and autonomic impairment, with significant implications for DHD, which results from a complex interplay among coronary micro- and macro-vascular circulation, neuro-immune control, and myocardial damage.

Objective: To characterize the complexity of DHD and its determinants by comparing AID and T2D.

Methods: DHD will be studied in individuals with AID, T2D, and healthy controls matched for cardiovascular risk factors. Advanced echocardiography and cardiovascular magnetic resonance will allow high-quality assessment of the different components of DHD (such as cardiac geometry, performance, and contraction). To identify the determinants of DHD, cardiac study results will be correlated with autonomic dysfunction tests, markers of small fiber neuropathy, and laboratory assessments of metabolic alterations, cardiac autoimmunity, and the inflammasome. Furthermore, genetic susceptibility to autoimmune diabetes and pancreatic autoimmunity will also be evaluated and correlated with DHD

Interventions

  • Diagnostic testCardiac Magnetic Resonance

    Cardiac Magnetic Resonance is an imaging technique for the assessment of the function and structure of the CV system, with high accuracy and reproducibility. Further, CMR enables to non-invasively evaluate coronary microvascular circulation and tissue characterizing the myocardium

What researchers measure

Primary outcomes

  1. Difference between LADA and T2D in the distribution in the identified clusters of diabetic heart disease

    Cluster analysis based on measures of cardiac geometry and function derived from cardiac imaging will be used to define clusters of cardiac phenotypes. Differences in the distribution of groups in cardiac clusters will be tested

    Time frame: Baseline, pre-procedure

Secondary outcomes

  1. Differences in circulating markers of metabolic and cardiovascular health between groups

    Time frame: Baseline, pre-procedure

  2. Relationship of the circulating markers of metabolic and cardiovascular health with cardiac structure and function evaluated by cardiac imaging

    Time frame: Baseline, pre-procedure

  3. Relationship between small nerve fibers damage with cardiac structure and function

    Relationship between markers of small nerve fibers damage derived from corneal confocal microscopy and from cardiac autonomic reflex tests with cardiac structure and function evaluated by cardiac imaging

    Time frame: Baseline, pre-procedure

  4. Differences in cardiac autoimmunity between groups

    Differences in the prevalence and levels of cardiac autoantibodies and in genetic predisposition to autoimmune diabetes between groups and their relationship with cardiac structure and function evaluated by cardiac imaging

    Time frame: Baseline, pre-procedure

Other outcomes

  1. Differences in extracellular vescicles (EV) and markers of inflammasome activation between groups

    Time frame: Baseline, pre-procedure

  2. Relationship of different EV and inflammasome profiles with cardiac structure and function evaluated by cardiac imaging

    Time frame: Baseline, pre-procedure

  3. Longitudinal changes of cardiac contraction, geometry and coronary artery microcirculation, in relation to metabolic profile and inflammasome markers.

    Time frame: Through study completion, an average of 2.5 years
