Cardiology was present since the very beginning of the Erasme hospital. The Department of Cardiology was created in 1979. This department is made of a hospitalization unit (54 beds), a coronary care unit (12 beds) and a large technical unit. Clinical activity has increased tremendously and this had led to an important research activity in the fields of cardio-respiratory and metabolic adaptation to exercise, particularly after cardiac transplantation, of cardiovascular epidemiology, of clinical pharmacology and in pulmonary as well as systemic hypertension.
