Acute ECG ST-segment elevation mimicking myocardial infarction in a patient with pulmonary embolism

Cardiovasc Ultrasound. 2010 Nov 24;8:50. doi: 10.1186/1476-7120-8-50.


Pulmonary embolism is a common cardiovascular emergency, but it is still often misdiagnosed due to its unspecific clinical symptoms. Elevated troponin concentrations are associated with greater morbidity and mortality in patients with pulmonary embolism. Right ventricular ischemia due to increased right ventricular afterload is believed to be underlying mechanism of elevated troponin values in acute pulmonary embolism, but a paradoxical coronary artery embolism through opened intra-atrial communication is another possible explanation as shown in our case report.
