Why the study?
Does pharmacologic stress SPECT predict perioperative cardiac events in patients undergoing aortic surgery?
Does pharmacologic stress SPECT predict perioperative cardiac events in patients undergoing aortic surgery?
Pharmacologic stress SPECT, particularly a summed stress score >=14, is a valuable tool for preoperative risk stratification in patients undergoing high-risk aortic surgery.
May inform preoperative risk stratification before aortic surgery; leaves open whether SPECT-guided decisions improve outcomes.
