Troponin Elevations Following Vascular Surgery in Patients Without Preoperative Myocardial Ischemia

Objectives: A normal preoperative myocardial perfusion-imaging (MPI) test in advance of vascular surgery predicts a low risk of postoperative clinical events at 30 days. Among patients undergoing vascular surgery with a normal preoperative MPI, cardiac troponin I (cTnI) elevations are common and predictive of a poor long-term outcome. Methods: The…
