We fully agree that differences in patient population may have contributed to the observed variations in NPV. However, the fact that our study focused on patients with symptomatic rather than asymptomatic CAD is of major clinical relevance. In patients with symptomatic CAD, hs-cTnI cutoffs even lower than 2.5 ng/L fail to accurately exclude inducible myocardial ischemia. Similarly, even in subgroups of patients with symptomatic CAD with similar or even lower pretest probability of inducible myocardial ischemia than the ...Reference1.
