Pulmonary embolism presenting with evolving electrocardiographic abnormalities mimicking anteroseptal myocardial infarction: a case report

Med Princ Pract. 2011;20(6):577-80. doi: 10.1159/000330030. Epub 2011 Oct 4.


Objectives: To report a case with dynamic ST segment elevation suggestive of anteroseptal acute myocardial infarction (AMI) that proved to be bilateral pulmonary thromboembolism (PTE).

Clinical presentation and intervention: A 50-year-old woman with syncope was transferred to the emergency department. Findings from the admission electrocardiogram were suggestive of anteroseptal AMI; however, coronary angiography revealed that the patient had normal coronary arteries. On further evaluation, the patient was found to have massive bilateral PTE.

Conclusion: This report emphasizes the role of evolving electrocardiographic changes in the diagnosis of PTE, particularly in patients with chest pain and ST segment elevation suggestive of acute coronary syndrome.
