COVID-19 Induced Myocarditis: A Case Study and Comprehensive Clinical Review

Abstract

Background: COVID-19, caused by SARS-CoV-2, is a respiratory illness that has systemic manifestations, including cardiovascular complications. Myocarditis, or inflammation of the heart muscle, has emerged as a significant cardiac consequence of COVID-19, especially in moderate to severe cases. Case Presentation: This case study presents a 42-year-old male patient with no prior cardiac history who developed myocarditis two weeks after recovering from a moderate COVID-19 infection. He presented with chest pain, palpitations, fatigue, and dyspnea on exertion. ECG, elevated troponins, echocardiography, and cardiac MRI confirmed the diagnosis. Management: The patient was treated with supportive care, beta-blockers, corticosteroids, and ACE inhibitors. He showed gradual improvement over four weeks, with normalization of cardiac enzymes and improved ejection fraction. Conclusion: COVID-19-induced myocarditis, while uncommon, can present with serious cardiac complications even in patients with no prior cardiac history. Prompt diagnosis and early intervention are crucial for favorable outcomes. This case highlights the need for long-term cardiac monitoring in post-COVID-19 patients, especially those with persistent cardiovascular symptoms.
