Researchers at the University of Bern and Inselspital and the University Hospital Bern are exploring the use of artificial intelligence in the personalized treatment of heart muscle inflammation i.e. myocarditis.

Bern/Switzerland – Myocarditis (inflammation of the heart muscle) is usually caused by viruses, including the Covid-19 virus. However, it can also be caused by medication, toxic substances or in the context of a rheumatological disease. Clinical assessment is difficult because symptoms vary widely, from fatigue to chest pain, palpitations, shortness of breath, and, rarely, sudden cardiac death, the latter associated with exercise. Today, cardiac magnetic resonance imaging (CMR) is usually performed when myocarditis is suspected. But the data obtained here from by itself do not yet allow sufficiently personalized risk assessment and appropriate treatment in certain cases.

In a scientific review in collaboration with the University of Tübingen, the Bristol Heart Institute and Harvard Medical School, a research group led by Prof. Dr. Christoph Gräni, MD, from Inselspital and the University of Bern assessed various cardiac MRI parameters in terms of their importance for diagnosis, prognosis and monitoring in myocarditis.


"From the comparison of the different diagnostic tools used so far, we can derive new approaches for future research and development. Next, we will determine how artificial intelligence (AI) can assist us in a rapid and comprehensive evaluation of the many different clinical parameters and image data," said Christoph Gräni. "To this end, I am pleased that we have received funding from the Bern Center for Artificial Intelligence in Medicine (Caim) to pursue this promising research direction."

Making complex cardiac function data readable with AI

In CMR, more than 1000 measurements can be collected per patient, including parameters on anatomy, tissue characterization of the heart muscle and pericardium (e.g., inflammation or scars), and heart muscle function data. Physicist Yasaman Safarkhanlo, who is completing her dissertation project under the supervision of Prof. Gräni at the Department of Cardiology at the Inselspital, explains: "Only AI can evaluate these many variables quickly in their entirety. We want to let the data speak to better understand what exactly happens during myocarditis. This is a new approach that does not start from our previous understanding of physiology and looks for a known feature on the images. Rather, with our project, we're starting from the data side to see what new correlations we discover on the images – so we can offer better treatment in the future."

Targeted counseling of athletes

The researchers' objective is to develop evaluation tools that can be used to determine in individual patients whether myocarditis will heal spontaneously and sustainably or whether close monitoring is needed. "Especially athletes could be better advised in this way: On the one hand, the goal is to avoid sudden cardiac death, but on the other hand, not to unnecessarily restrict athletes in their activity," Gräni explains. To this end, all clinical data and image data will one day flow into the Insel Gruppe's digital clinical information and control system (Kiss), where they will be automatically evaluated in order to provide the attending physician with a probability of diagnosis, a prediction of the course of the disease, and a suitable therapy suggestion.

Focus on digitalization and AI applications in medicine

The Department of Cardiology's commitment to using the latest digital technologies for personalized medicine comes at a strategically opportune time with the digitalization projects at the Insel Gruppe and the University of Bern. "The Faculty of Medicine of the University of Bern is strongly committed to digitalization in medical education and research. With the establishment of the Center for Artificial Intelligence in Medicine (Caim) the university and the Insel Guppe have created an excellent research platform. It allows utilizing the latest developments in cutting-edge digital technology and artificial intelligence for personalized treatment approaches and to anchor this knowledge in education and training," says Prof. Claudio Bassetti, MD, Dean of the University's Faculty of Medicine and Director and Chief Physician of the Department of Neurology at Inselspital.

Caim selects myocarditis project for research funding

During the recent first round of Caim's research funding, the myocarditis project was selected along with four others and will receive CHF 100,000. Caim director Prof. Raphael Sznitman says: "There is a tremendous up-swing to having clinicians from the Inselspital and technical scientists from the University working closely together. By bringing dynamic and driven individuals to reach beyond their trained disciplines, the potential to innovate and impact our healthcare system is simply boundless. This is at the core of Caim and we are very excited to see such partnerships thrive."
