Periodic Reporting for period 4 - DIAMONDCOR (A molecular approach to treat diabetes mellitus onset dependent coronaropathy)

Reporting period: 2021-07-01 to 2022-12-31

Summary of the context and overall objectives of the project

As frequent and severe metabolic disorder, diabetes mellitus (DM) affected 422 million people worldwide in 2014 with rising incidence, especially in developed countries. In Europe, 59 million patients suffer from DM with health costs of 142 billion Euros per year. As one of the most challenging consequences, diabetes inflicts cardiovascular disease leading to cardiomyopathy and cardiac death: Diabetes affects many organ systems including micro- and macro-circulation. As most frequent sequela, diabetes mellitus affects coronary vessel function and thus proper blood perfusion of the heart. Consistently, myocardial infarction and subsequent heart failure are the most common causes of death in diabetic patients.
Therefore the overall objective of DIAMONDCOR is to address micro-vessel disease in diabetic hearts. We aim to assess the reversibility of diabetic myocardial dysfunction by specific molecular interventions for vessel stabilization as well as neovascularization.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Diabetes mellitus leads to an impairment of the cardiac microcirculation, thereby influencing cardiac function. Furthermore, theses changes in the diabetic heart lead to an increase in infarct size as well as a reduced cardiac function after acute myocardial infarcts in pigs. Monitoring of the microcirculatory state in diabetic cardiomyopathy is important and is one of the major goals in DIAMONDCOR. Furthermore, we have fist evidence, that normalization of the micro-circulation in diabetic cardiomyopathy leads to an improved cardiac function, thereby reducing signs of heart failure.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

Within DIAMONDCOR we try to develop novel imaging modalities, which can be translated to the human situation and might be suitable for the monitoring of diabetic cardiomyopathy as well for therapeutic success in cardiac disease. Furthermore, we would like to establish a preventive therapy for diabetic cardiomyopathy, to increase outcome after cardio-vascular events for diabetic patients.
