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).
