The other patient had mixed connective tissue disease in the past, and lupus was the main manifestation of this disease. At the onset of the disease, all patients had chest tightness and shortness of breath; two patients had a fever, and the markers of myocardial injury increased. Cardiac color Doppler ultrasound indicated that left ventricular ejection fraction decreased significantly. Cardiac insufficiency with cardiogenic shock rapidly appeared as the main manifestation. Two patients immediately started veno-arterial extracorporeal membrane oxygenation (VA-ECMO), and ECMO was also started in one patient after a pacemaker placement was ineffective. For all three patients, high-dose hormones were given to control the primary disease, and then the ECMO machines were removed successfully.Conclusion: VA-ECMO treatment should be implemented in patients with hemodynamically unstable LM as soon as possible to maintain the patient’s hemodynamics and help them overcome the crisis of cardiac dysfunction, allowing more time for primary disease treatment.Keywords: VA-ECMO, lupus myocarditis, hemodynamic instability
