What are some clinical features associated with myocarditis?

Myocarditis is an inflammation of the heart muscle that can present with a range of clinical features. Chest pain is commonly reported as it can occur due to inflammation or involvement of the heart's myocardium. EKG abnormalities are significant in diagnosing myocarditis, as changes such as ST-segment elevation or depression, T-wave inversions, and arrhythmias can be observed. Additionally, symptoms of pericarditis, such as sharp chest pain that may worsen with inspiration or coughing, can occur alongside myocarditis due to the close anatomical and functional relationship between the myocardium and pericardium.

While other options mention various symptoms, they do not encompass the hallmark features strongly associated with myocarditis. Options that list only shortness of breath and joint pain, palpitations and severe headaches, or fever and persistent cough do not reflect the typical clinical picture that includes more specific signs like chest pain and EKG changes. Thus, the presence of chest pain, EKG abnormalities, and symptoms associated with pericarditis form a triad that is more indicative of myocarditis.
