In Reply In our study, we found that noninvasive coronary artery disease (CAD) testing was associated with more downstream testing and revascularizations compared with no testing in emergency department (ED) patients with low-risk chest pain but found no difference in 6-month myocardial infarction (MI) rates.1 In his letter, Dr Hartlage, using several risk models, highlights differences in expected risk in our testing and no-testing groups based on age alone and suggests that noninvasive testing led to therapeutic measures that mitigated risk in our testing cohort.
