Pulmonary embolism mimicking acute myocardial infarction.

Pulmonary embolism is a major cause of death in the United States. A high index of suspicion is required to achieve an accurate diagnosis. We report a case of a patient with syncope, ischemic electrocardiographic changes, and an elevated troponin I level, presenting just like acute myocardial infarction. The case highlights the value of an early use of 2-dimensional echocardiography in obtaining an accurate diagnosis, thus avoiding unnecessary and inappropriate treatment.
