Key result
A woman in her late 30s with viral myopericarditis rapidly decompensated due to seronegative immune-mediated necrotising myopathy, developing cardiogenic shock requiring intra-aortic balloon pump.
Case Report (n=1)
This case highlights the potential for seronegative immune-mediated necrotising myopathy to present with fulminant myocarditis and cardiogenic shock.
May warrant close monitoring for fulminant progression in myopericarditis; extends case reports on cardiogenic shock but leaves practice unchanged.
A woman in her late 30s recently diagnosed with viral myopericarditis presented with 1 month of worsening fatigue, diffuse myalgias and chest pain radiating to her back. While undergoing work-up for chest wall myositis, she rapidly decompensated, developing heart failure and acute hypoxaemic respiratory failure. Her clinical course was complicated by cardiac arrest and severe cardiogenic shock requiring intra-aortic balloon pump support.

Tsang et al. (2022) conducted a case report in Seronegative immune-mediated necrotising myopathy complicated by fulminant myocarditis (n=1). A woman in her late 30s with viral myopericarditis rapidly decompensated due to seronegative immune-mediated necrotising myopathy, developing cardiogenic shock requiring intra-aortic balloon pump.
