In patients with low risk chest pain (TIMI score 0-2), this large trial randomized patients to usual care, or to CTA imaging. Of those with a negative CTA, none experienced death or MI within 30 days. Those in the CTA group had higher rates of ED discharge (50% vs 23%) and shorter total LOS (18 vs 25 hours).
