T h e common our diagnostic and therapeutic abilities, most of our part of the three circles is the zone of so-called activities are palliative only. We are frequently able to "translational" medicine. In the future, a major improve the quality and length of life, but we can very challenge will be to create a new breed of cardiologists rarely cure our patients. With hope, what we will see in working in that zone with sufficient understanding the next century and beyond is a gradual replacement of of both the basic and the clinical aspects of palliative treatment by curative therapy, with ultimately cardiology to translate basic information into clinical a marked reduction and disappearance of cardiovascular application. diseases by preventive measures (figure).
