Introduction:Myocardial metastatic cancer is rare, and diagnosis is challenging. Supradiaphragmatic malignancies are the most common to metastasize to the heart. Endocardial involvement is rare, followed by involvement of the pericardium, epicardium, and myocardium. Myocardial metastasis leads to varied clinical presentations ranging from arrhythmias, congestive heart failure, myocardial infarction, and intracavitary mass lesions (1). We are describing a patient with a prior diagnosis of coronary artery disease (CAD) and Coronary artery bypass graft (CABG) presenting as recurrent ST-elevation myocardial infarction (STEMI) and diagnosed with cardiac metastasis from lung squamous cell carcinoma (SCC).
