Myocardial injury after noncardiac surgery MINS is defined as myocardial injury caused by ischemia that occurs during or within 3. Diagnostic criteria for MINS, based on the nonhigh sensitivity troponin T assay, have been identified. US Food and Drug Administration recently approved use of the high sensitivity troponin T hs. Tn. T assay, and globally, many hospitals are using high sensitivity troponin assays. Little is known about the relationship between perioperative hs. Tn. T measurements and 3. A large international study, the Vascular Events in Noncardiac Surgery Patients Cohort Evaluation VISION Study, was undertaken to assess perioperative complications. Among adults who underwent noncardiac surgery and had a postoperative hs. Tn. T measurement, the primary objective was to determine the association between perioperative hs. Tn. T measurements and 3. MINS based on hs. Tn. T. The secondary objectives were to 1 determine if there was an interaction between the lowest prognostically important postoperative hs. Tn. T threshold ie, the lowest hs. Tn. T threshold that was independently associated with patients risk of 3. HR 3. 0 and a risk of 3. GFR or sex 2 describe the characteristics of patients experiencing MINS and their outcomes and 3 determine the proportion of MINS that might go undetected without troponin monitoring. Methods. Study Design and Participants. The VISION Study was a prospective cohort study of a representative sample of adults who underwent noncardiac surgery. In the first 1. 5 0. Tn. T was measured and its association with 3. MINS was evaluated and reported. In the second half of the study, hs. Tn. T measurements were obtained in more than 2. This represents the focus of this article. Eligible patients were aged 4. Patients were excluded if they were previously enrolled in VISION or did not provide informed consent. Appendix 1 in the Supplement reports additional exclusion criteria related to the secondary objectives. The institutionalethics review board at each site approved the protocol before patient enrollment commenced. Patients provided written informed consent before surgery unless they were unable eg, emergency surgery, in which case research personnel obtained consent within the first 2. Seven centers used a deferred consent process for patients unable to provide consent eg, patients sedated and mechanically ventilated and for whom no designated decision maker was available. This allowed collection of data while awaiting the patients or designated decision makers consent. Procedures. Details regarding participant screening and procedures to ensure a representative sample are reported in e. Appendix 2 in the Supplement. Research personnel interviewed and examined patients and reviewed charts to obtain data on variables potentially associated with perioperative complications. Patients had blood collected for measurement by the Roche fifth generation Elecsys hs. Tn. T assay 6 to 1. Patients enrolled between 1. Tn. T measurement immediately, and testing continued as described above. During the later phase of the study, hs. Tn. T measurement was added before surgery. The majority of hospitals analyzed the hs. Tn. T measurements of their patients and reported the results to clinicians. Two UK centers blinded clinicians to hs. Tn. T results. In the United States, where hs. Tn. T was not approved for clinical use at the time of conducting the VISION Study, blood samples were collected, processed, frozen, and analyzed for hs. Tn. T at a later date. For US participants, the fourth generation non hs. Tn. T assay was used and clinicians received these results however, analyses for this study are restricted to the hs. Tn. T measurements. Throughout hospital stay, research personnel evaluated patients, reviewed hospital charts, ensured that patients had hs. Tn. T measurements completed, and noted outcomes e. Appendix 3 in the Supplement. Patients with an hs. Tn. T level of at least 1. L ie, threshold considered abnormal by manufacturer4 were assessed for ischemic features eg, ischemic symptoms, ischemic electrocardiographic findings defined in e. Appendix 4 in the Supplement. Centers were encouraged to obtain electrocardiograms for several days after an hs. Tn. T measurement result of at least 1. L and to obtain hs. Old Time Radio S Gunsmoke'>Old Time Radio S Gunsmoke. Tn. T measurements and electrocardiograms if patients experienced an ischemic symptom. Exceptions to these procedures occurred in the 2 centers that blinded clinicians to the hs. Tn. T results and among US participants with an hs. Tn. T level of at least 1. L but a non hs. Tn. T level of less than 0. L ie, threshold considered abnormal by manufacturer. For these patients, study personnel reviewed clinical notes for ischemic symptoms, but no electrocardiograms were obtained. Study personnel telephoned patients at 3.
