Inflammation in Cardiometabolic Diseases
Our Scientific Focus
Although the mortality rate from cardiovascular diseases has been reduced over the past 50 years, among other reasons due to innovations in medical care, cardiovascular diseases continue to be the leading cause of death worldwide. In particular, patients with diabetes mellitus and chronic kidney disease (CKD) exhibit a significantly increased cardiovascular risk. To reduce cardiovascular morbidity and mortality, new therapeutic targets need to be identified and translated into clinical practice. Data from the last two decades have demonstrated that inflammatory processes play an important role in cardiovascular diseases such as atherosclerosis, myocardial infarction, and heart failure. It has been shown that inflammatory networks between blood vessels, the myocardium, bone marrow, spleen, sympathetic nervous system, and the gut significantly influence both the development and progression of cardiovascular and cardiometabolic diseases.
The focus of our research group is to better understand the underlying molecular mechanisms of these inflammatory networks within the framework of organ crosstalk and to derive new immunological therapy targets from this understanding. We are particularly interested in intestinal mediators (such as the incretin hormones GLP-1, GLP-2, and GIP) and immune cells from the gut (e.g., intraepithelial lymphocytes). Through a bench-to-bedside approach, we aim to validate observations from basic research in clinical studies (registries, biobanks, epidemiological studies, interventional studies).

IMR Blue Zone
IMR Blue Zone is an EU project funded by Interreg, which is divided into four work packages and was initiated in collaboration with Hasselt University, Maastricht University, and the University of Liège.
Current population-based studies show that there are significant differences in life expectancy within the Rhine-Meuse region. These differences occur both between individual regions and in comparison to their respective national averages. Against this backdrop, the IMR Blue Zone project was launched to investigate the causes of these disparities as well as lifestyle differences more closely.

In the first two work packages, health-related habits and cardiovascular risk factors will be collected and analyzed through an intervention study using wearables, blood analyses, and questionnaires. Targeted physical activity interventions aim to positively influence health-related behavior. The goal is to identify possible lifestyle differences in the Rhine-Meuse region. Furthermore, curricula of health-related degree programs at the participating universities will be compared to highlight differences in the teaching of preventive medicine content.
In the fourth work package, a survey will be conducted among physicians in the four regions. The aim is to examine the extent to which preventive measures and lifestyle modifications are implemented in clinical practice and communicated to patients.

The “Kardio-AG” Aachen is the local student initiative within the framework of Young DGK and closely connects the Aachen site with nationwide youth activities. We offer practical formats such as interactive case discussions, introductory courses in echocardiography, short skills sessions, as well as insights into research, doctoral pathways, and career planning. Our goal is to provide easy access to cardiology that brings together clinical practice and scientific work at the University Hospital RWTH Aachen.
The AG is led by our Youngest DGK Ambassador Alessandra Antwerpen together with Marieke Mertens and Konstantin Rex; medically supervised by Prof. Dr. Florian Kahles and Dr. Berkan Kurt. We regularly communicate dates, topics, and participation opportunities through our channels at the Aachen site. Anyone interested in participating, contributing, or seeking information can contact us at any time.
