Our latest cardiology case report from Dr. Brady Pregerson features a woman in her mid-20s presenting to the emergency department with chest pain for the last 24 hours and a slight cough.
History: A woman in her mid-20’s presents to the hospital with intermittent, non-exertional, non-pleuritic chest pain for the last 24 hours associated with a very slight cough. The pain is also in her epigastric area and she did vomit twice as well. The pain episodes last from 5-45 minutes. She’s never had this before. She denies any shortness of breath, diarrhea, fever, or other complaints and has no known COVID exposures although she went to an amusement park recently.
PMH: Asthma, incidental pericardial effusion and enlarged liver noted on CT for appendicitis years ago, both of which resolved on follow-up imaging.
Exam: Vital signs are normal as is her BMI. Exam is notable for clear lungs without wheezing and mild epigastric tenderness.
