A 45-year-old man had coronary artery stents placed 2 days ago. Today, he is in
severe distress and is reporting "crushing" chest discomfort. He is pale, diaphoretic,
and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mm Hg,
respiratory rate is 28 breaths per minute, and oxygen saturation is 89% on room air.
When applied, the cardiac monitor initially showed ventricular tachycardia, which then
quickly changed to ventricular fibrillation. On the basis of this patient's initial
presentation, which condition do you suspect led to the cardiac arrest? - correct
answer Acute coronary syndrome
