Tumor Invasion of Myocardium Presented with Acute Coronary Syndrome.
Cardiac metastases of malignant tumors are rare but associated with various presentations, including arrhythmia, heart failure and myocardial infarction. However, it may also cause typical electrocardiographic (ECG) changes, mimicking ST-segment elevated myocardial infarction (STEMI) when patients have chest pain. We reported a 59 year-old woman with cardiac metastases of buccal squamous cell carcinoma, which presented with myocardial infarction ECG pattern due to both atrial and ventricular involvements. Rather than alternatives to emergent coronary angiogram may be considered, thrombolytic therapy for acute myocardial infarction could be inappropriate in that it creates a risk for patients with malignancies in certain situations mimicking STEMI.
