Notoriously elusive, with a high misdiagnosis rate, thoracic aortic dissection (AD) can mimic many conditions, including acute coronary syndrome (ACS, the most common), gastroesophageal reflux disease (GERD), stroke, and spinal-cord compression. The patient is admitted for ACS to a cardiologist who says he will see the patient in the morning.
