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

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.
