Cardiac sarcoidosis is a rare condition which affects a small number of people who suffer from a condition called sarcoidosis – an inflammatory condition that can affect multiple organs. The disease tends to affect younger people, generally between 25 and 45 years old. Sarcoidosis is characterized by the presence of granulomas. These are ball-like collections of inflammatory cells that cluster around and react to a foreign substance. The inflammation associated with granulomas can damage virtually every part of the heart, including the electrical system, muscle, valves, arteries and surrounding tissue called the pericardium.
