This is a type of medical treatment that suppresses the immune system. This can be done to prevent the body's immune cells from attacking healthy tissue, as seen in autoimmune diseases, or to prevent rejection of transplanted organs. In the case of myocarditis, a viral or autoimmune attack on the heart muscle, immunosuppressive therapy may be used as a treatment option in some pediatric patients. This helps to reduce inflammation and prevent further myocardial injury & damage to the heart. The use of immunosuppressive therapy in myocarditis can vary based on the underlying cause and severity of the condition.
