CCTA May Be More Effective in Evaluating Women with Acute Chest Pain
Cardiac computed tomographic angiography (CCTA) performed in the emergency department (ED) may be an alternative to standard ED evaluation for women presenting with symptoms suggestive of acute coronary syndromes (ACS). The findings, based on a prespecific subgroup analysis of the Rule-Out Myocardial Infarction with Computer-Assisted Tomography (ROMICAT)-II trial, were published May 17 in Circulation.
The authors suggest the findings are attributable to the lower rate and severity of ACS in women, and that CCTA is an "attractive alternative" to standard evaluation strategies. Nevertheless, they caution, "the small number of major adverse events in this low-intermediate risk sample precludes definitive conclusions as to whether there is a greater benefit for women than men undergoing CCTA. The lack of follow-up beyond 28 days in this trial limits the ability to examine potential longer-term benefits ... [and] the newest CT scanners may not be commonly available."
Moving forward, the authors note that CCTA may be a useful alternative to standard ED evaluation of women with ACS symptoms, but larger trials and more widespread availability of the technology will be needed to determine CCTA's definitive role in ED chest pain protocols.
