Cardiac abnormalities are common in patients with systemic lupus erythematosus (SLE). However, many of them tend to be mild or asymptomatic and can be recognized by non-invasive studies such as transthoracic echocardiography and cardiac magnetic resonance imaging (CMR). However, heart failure secondary to perimyocarditis as the initial manifestation of SLE remains an extremely rare form of presentation. Below, we present the case of an adult female patient who initially consulted due to symptoms of acute dyspnea, atypical chest pain, and edema of the lower limbs, who underwent a chest X-ray as part of the initial studies, which described an increase in the cardiac silhouette associated with diffuse opacities in both lung fields. The admission electrocardiogram only showed sinus tachycardia and nonspecific alterations of the T wave, with an initial report of frankly elevated cardiac biomarkers compatible with acute myocardial injury together with the positivity of specific antibodies for SLE.
