Influenza-virus-vaccine: Acute myocarditis.

A 32-year-old man experienced acute myocarditis after receiving the influenza-virus-vaccine. He presented with chest pain, reduced exercise tolerance, and shortness of breath. His cardiac markers were elevated, and an EKG showed abnormalities. Treatment included aspirin and colchicine, and a cardiac MRI confirmed the diagnosis of myocarditis. The man was discharged with outpatient follow-up and advised to avoid strenuous activity. The article suggests a potential link between the influenza vaccine and acute myocarditis, but further research is needed to establish causation. [Extracted from the article]
