Clinical utility of preoperative stress perfusion cardiac magnetic resonance for predicting cardiovascular events in patients undergoing major noncardiac surgery

Figure 1.. Study flow chart.

Figure 2.. The risk of in-hospital or 30-day MACE compared between those with and without inducible ischemia relative to the surgical risk category (compared between intermediate- and high-risk surgery) and RCRI score (compared among RCRI scores of 0, 1, and >1). Abbreviations: MACE: major adverse cardiovascular events; RCRI: Revised Cardiac Risk Index.

Figure 3.. Kaplan–Meier Survival analysis showing the cumulative incidence of an in-hospital or 30-days MACE compared between patients with and without inducible ischemia. Abbreviations: MACE: major adverse cardiovascular events.

Figure 4.. Kaplan–Meier survival analysis of the risk of in-hospital or 30-day MACE relative to RCRI scores of 0-1 and >1 (A, B) as well as high- and intermediate-risk surgeries (C, D), all of which were compared between patients with and without inducible ischemia. Abbreviations: MACE: major adverse cardiovascular events; RCRI: Revised Cardiac Risk Index.

Figure 5.. Kaplan–Meier survival analysis of the risk of in-hospital or 30-day MACE, comparing patients with and without inducible ischemia across various types of surgery (intraperitoneal [A], oncologic [B], orthopedic [C], and vascular surgery [D]). Abbreviations: MACE: major adverse cardiovascular events.
