Based on data from the NCSI database, operator decisions to perform multivessel revascularization were associated with similar outcomes to cultprit only vessel PCI making (b) the correct answer. These findings are different than described in the CULPRIT Trial which forced operators to perform complex PCI including chronic total occlusions and other high-risk lesions. The NCSI operators tended to avoid such lesions while still performing more complete revascularization in patients with multivessel culprit lesion. Thus, kidney and mortality outcomes were not worse making (a) incorrect, despite slightly higher contrast use, making (c) incorrect, likely because of the benefits of hemodynamic support to improve kidney support in the NCSI whereas only 15% of patients in the CULPRIT Shock Trial received similar hemodynamic support, making (d) incorrect.
