Coronary CTA Has One Year Warranty Period

Hollander JE, Gatsonis C, Greco EM et al. Coronary Computed Tomography Angiography Versus Traditional Care: Comparison of One-Year Outcomes and Resource Use. Ann Emerg Med. 2015 Oct 22. pii: S0196-0644(15)01302-5. doi: 10.1016/j.annemergmed.2015.09.014 [Epub ahead of print]

CONCLUSION: A coronary CT angiography-based strategy for evaluation of patients with low- to intermediate-risk chest pain who present to the ED does not result in increased resource use during 1 year. A negative coronary CT angiography result is associated with a less than 1% major adverse cardiac event (MACE) rate during the first year after testing. PMID: 26507904

Comment: The coronary CTA group and traditional group had the same (1%) incidence of MACE, so it appears the warranty period on  coronary CTA is at least 1 year.
