Acute Peripartum Myocarditis Mimicking Acute Coronary Syndrome: A Case Report

Acute myocarditis occurring during pregnancy or the peripartum period is a rare but potentially serious condition, with a polymorphic clinical presentation that may mimic acute coronary syndrome, making diagnosis challenging. We report the case of a 30-year-old woman, G3P2, admitted at 38 weeks and 3 days of gestation for atypical chest pain associated with palpitations. Clinical examination revealed sinus tachycardia without signs of heart failure. Laboratory investigations showed a marked elevation of troponin with an ascending kinetic profile, while electrocardiography and transthoracic echocardiography were normal, with preserved left ventricular systolic function. After exclusion of the main coronary etiologies and multidisciplinary discussion, the diagnosis of acute peripartum myocarditis was retained. This case highlights the importance of considering acute myocarditis in pregnant or peripartum women presenting with chest pain and elevated troponin levels, even in the absence of electrocardiographic or echocardiographic abnormalities.
