Patients with evidence of myocardial injury following non-cardiac surgery (MINS) are at increased risk of death postoperatively.

Risk stratification and selective revascularization of high-risk individuals has been shown to reduce cardiovascular events in the non-perioperative MI setting. However, its utility in MINS is not established.

In the SPECT MINS study, patients underwent Stress Single Photon Emission Computed Tomography Myocardial Perfusion Imaging (SPECT MPI) shortly after the identification of MINS, and were followed for six months post-surgery.

We evaluated whether the amount of ischemia identified on pharmacological stress testing with SPECT MPI predict death, myocardial infarction, heart failure or coronary revascularization at 6 months after surgery.
