The university hospital Rechts der Isar’s Department of Internal Medicine I: Cardiology, angiology, and pulmonology, is headed by Prof. Dr. med. Karl-Ludwig Laugwitz. The department has a team of 8 senior physicians, 15 medical specialists and 26 medical assistants which specialize in the treatment of cardiological (heart disease), angiology (vascular disease) and pulmonological (lung disease) diseases. The most common heart diseases treated by the doctors of the department include angina pectoris (chest tightness), coronary heart disease (CHD), heart failure and heart attack. Patients are treated using innovative diagnostic and therapeutic procedures. As a university hospital affiliated with the Technical University of Munich, the department is highly active in scientific research. Some of the most common operations performed at the department are catheterization of the arteries on the left side of the heart (2459 cases), treatment of disorders of the coronary arteries (blood vessels surrounding the heart), and whole-body plethysmography. However, this is not a complete list of their services.

The Department of Cardiology, angiology, and pulmonology has 3 fully equipped wards and a day clinic. Their internal intensive care unit is certified by the German Cardiac Society as "Chest-Pain-Unit" (special ward for patients with acute chest pain). The dedicated team of specialized doctors and nurses ensures comprehensive and individual care for the patients. For diagnosis and therapy, various catheter laboratories, cardiac ultrasound examination sites (UKG) and other specialized facilities are available.
