![Staphylococcus aureus is a rare cause of myocarditis and typically affects immunocompromised patients with sepsis. S aureus myocarditis usually occurs with endocarditis and may result in the formation of abscesses on the heart valves and muscle.5 “As with viral myocarditis, this disease can present with signs and symptoms of acute myocardial infarction, complicating the diagnosis,” wrote the authors of a 2008 case study.12 “Much of the available data on bacterial myocarditis [were] collected before the development of many modern diagnostic tests and before antibiotics [thus] the appropriate workup, diagnosis and treatment remain unclear.”12 A case report published in 2018 described a 44-year-old man with rheumatoid arthritis taking methotrexate who was diagnosed with S aureus myocarditis (and associated left ventricular apical thrombus) after having septic shock.13 Complete recovery was achieved with a 12-week course of antibiotics and anticoagulation.](https://103luf14i1lu362zph3gadzb-wpengine.netdna-ssl.com/wp-content/uploads/sites/16/2021/03/7staphylococcusaureusgetty1_1479047-507x306.jpg)
