An 80 year-old Chinese male with a history of tobacco
use and asthma presented to the ER complaining of
shortness of breath that was unresponsive to
bronchodilator use. The patient’s ECG on admission was
sinus rhythm at 95 beats per minute with minimal ST
elevations in V2-V4. Laboratory results were significant
for a troponin of 7.7. The patient was started on anticoagulation
with heparin. A transthoracic echocardiogram
revealed an ejection fraction of 25%. The patient
underwent coronary catheterization, which revealed
luminal irregularities of his coronary arteries. Figures 1
and 2 show the end diastolic and end systolic left
ventriculograms from the catheterization, respectively.
