Key result
Massive pulmonary embolism can present with ST-segment elevation mimicking acute myocardial infarction without coronary artery disease.
Case Report (n=1)
New ST elevation in cancer patients may signal massive PE; leaves open whether enhanced VTE screening improves outcomes.
An elderly man with a recent diagnosis of invasive rectal adenocarcinoma was admitted to the hospital because of a lower gastrointestinal bleeding and low haemoglobin. During the hospitalisation he complained of chest pain. ECG showed new onset ST-segment elevation in leads III, aVF and in the precordial leads V1-V4. Shortly thereafter, he became hypotensive and coded. Despite resuscitation he passed away. Autopsy revealed massive pulmonary emboli with near complete obstruction of the involved branches of the pulmonary arteries. Coronary arteries were free of significant coronary artery disease and multiple sections of the myocardium showed the absence of myocardial infarction.

Mohsen et al. (2013) conducted a case report in Pulmonary embolism (n=1). Pulmonary embolism was evaluated on Autopsy findings. Massive pulmonary embolism can present with new onset ST-segment elevation mimicking myocardial infarction in the absence of significant coronary artery disease.
