title: A case of ascending aortic dissection mimicking acute myocardial infarction and complicated with pericardial tamponade.
abstract: Acute aortic dissection (AD) is the most common life-threatening disorder affecting the aorta with an incidence that ranges between 5 to 30 cases per million people per year. The symptoms of aortic dissection may be variable and can mimic other more common conditions such as myocardial ischemia. We report a case of a 60-year-old male who presented with inferior wall ST-elevation myocardial infarction (MI). Emergent coronary angiography revealed an ascending aortic dissection with normal coronary arteries. In addition, his aortic dissection was complicated with pericardial tamponade. The patient was managed with an immediate surgical repair, after that he had an uncomplicated postoperative course and was discharged in a stable condition. This case report illustrates the importance of having a high index of suspicion for AD in cases of chest pain. If AD is suspected in a patient with acute coronary syndrome (ACS), confirming the diagnosis with the appropriate imaging studies should be done as quickly as possible, as misdiagnosis with ACS may lead to the inappropriate administration of thrombolytic or anticoagulant agents resulting in catastrophic outcomes.
