Overview
The symptoms associated with myocarditis are varied, and relate either to the actual inflammation of the myocardium, or the weakness of the heart muscle that is secondary to the inflammation.
History
Patients present with acute decompensation of cardiac function in patients with low cardiac risk or no obvious underlying cause. Demographics and clinical course should be taken into consideration in diagnosis of myocarditis.
A history of recent (2-4 weeks) viral illness may often be elicited in a large number of patients with myocarditis. Cardiac specific symptoms may become apparent usually in the subacute virus-clearing phase.
In hypersensitive myocarditis, patients may give a history of using offending drug.
Symptoms
Symptoms of myocarditis include:[1]
- Chest pain is often described as stabbing, pleuritic or sharp in character. In a series, 78% of patients were diagnosed with myocarditis when they presented with chest pain[2].
- Pedal edema in volume overload states.
- Breathlessness
- Dyspnea on exertion
- Orthopnea in pulmonary congestion.
- Palpitations
- Syncope in setting of high grade AV block
- Fever (especially when infectious, e.g. in rheumatic fever)
- Joint pains, and fatigue as seen in viral illness.
- Cynosis may also be seen in severe cases.
- Sudden death (in young adults, myocarditis causes up to 20% of all cases of sudden death)[3]. This probably can be attributed to ventricular tachycardia or fibrillation.
