  • Description: Whether these findings underscore a superior diagnostic performance of CTA and PET compared with SPECT--with a higher rate of "true positive" patients referred for ICA--or higher rates of therapeutic revascularization for symptomatic angina from obstructive CAD remains unelucidated. [...]although these data presented by the SPARC investigators represent an important step forward to address metrics beyond traditional measures of diagnostic and prognostic test performance, they nevertheless highlight the complexities associated with the conduct of such a study. Perhaps most prominently, the practice of CTA over the past several years has gained, not only in utilization, but also in familiarity, and changing practice patterns based upon CTA test findings are now observed. [...]although large-scale prospective studies of noninvasive CAD imaging are vital to our understanding of their integration into clinical practice, it remains a vexing proposition to conduct long-term or even intermediate-term investigations--such as is the case for SPARC--that represent a static moment in time for technologies whose development effectively outpaces the study.
