Preoperative Testing for Silent Coronary Ischemia Using Coronary CT Angiography-derived Fractional Flow Reserve (FFRct) May Reduce Postoperative Myocardial Infarction and Cardiovascular Death in Patients Needing Lower-extremity Revascularization Compared to Standard Pre-operative Evaluation of Patients With no Cardiac Symptoms Undergoing Peripheral Vascular Surgery

Introduction: Patients undergoing peripheral vascular surgery (PVS) have increased risk of post-op myocardial infarction (MI) and death due to coronary artery disease (CAD). Functionally significant coronary ischemia is often unrecognized since guidelines recommend no cardiac testing in patients with no CAD symptoms. A new non-invasive cardiac test, coronary CT angiography (CTA)-derived fractional flow reserve (FFRCT), reliably identifies ischemia-producing coronary stenosis in chest pain patients but its value in peripheral vascular patients is unknown.
