A 28-year-old man presented to the emergency department with chest pain. His medical history was significant only for chronic low-back pain due to a herniated lumbar intervertebral disk for which he was receiving meloxicam. He was a nonsmoker, worked as an aircraft mechanic, and had not recently traveled outside the country. Review of systems, with the exception of acute chest and chronic low-back pain, was negative. Vital signs and physical examination were normal.
