A 61-year-old female presents to urgent care with chest pain for 2 days. She describes it as “mild right now” but that it varies in intensity; it was so severe the previous night that it kept her from sleeping. Today the pain has been stuttering, lasting a couple of minutes at a time. Pain is substernal, nonradiating, and is associated with vomiting and diaphoresis. Vital signs are normal.
