Myocarditis is an acute inflammatory condition that can have an infectious, toxic or autoimmune aetiology. Myocarditis can complicate many infections in which inflammation may be due directly to infection of the myocardium or the effects of circulating toxins. The clinical picture ranges from a symptomless disorder, sometimes recognised by the presence of an inappropriate tachycardia or abnormal ECG, to fulminant heart failure. Myocarditis may be heralded by an influenza-like illness. In most patients, the disease is self-limiting and the immediate prognosis is excellent. However, death may occur due to a ventricular arrhythmia or rapidly progressive heart failure. Myocarditis has been reported as a cause of sudden and unexpected death in young athletes. Some forms of myocarditis may lead to chronic low-grade myocarditis or dilated cardiomyopathy. The case report describes a case of parainfectious myocarditis in a 20-year-old patient.
