Non-rheumatic Streptococcal Acute Myocarditis, also known as Strep Pharyngitis Acute Myocarditis (SPAM) occurs in young adults, typically within five days of the initial streptococcal pharyngitis, and is characterized by typical cardiac symptoms, abnormal electrocardiography, and elevated cardiac biomarkers in the absence of obstructive coronary artery disease. Patients may also report myalgias, arthralgias, and constitutional symptoms. Although a rare complication of Group A and G streptococcal infections, prompt recognition is important to ensure appropriate management.
