Why the study?
Does abnormal myocardial perfusion imaging predict adverse cardiac events in patients with known or suspected CAD and high exercise tolerance?
Does abnormal myocardial perfusion imaging predict adverse cardiac events in patients with known or suspected CAD and high exercise tolerance?
In patients with high exercise tolerance, abnormal myocardial perfusion imaging is a strong predictor of adverse cardiac events, whereas exercise ECG is not.
Abnormal MPI may stratify risk in high-exercise-tolerance CAD patients where ECG does not; leaves open need for prospective validation before practice change.
