The aim of cardiac management in DMD is early detection and treatment of the deterioration of heart muscle function (usually cardiomyopathy - involvement of heart muscle, or rhythm problems leading, for example, to palpitations) that commonly accompanies the overall progression of the disease. As this often happens silently (that is without the development of significant symptoms) it needs to be looked out for so it can be treated promptly. The key factors to consider in cardiac management are surveillance and proactive management. You need to be sure that there is a cardiologist involved with the care team.
