Cardiothoracic & vascular anesthesia
Association Between Hospital Postoperative Troponin Use and Patient Outcomes After Vascular Surgery
Authors' conclusion
Patients undergoing vascular surgery at hospitals with higher postoperative troponin testing intensity experienced fewer adverse outcomes than patients who had surgery at hospitals with lower testing intensity.
