González-Tallada A, Borrell-Vega J, Coronado C, et al. - In this observational analysis, researchers examined cardiovascular high-risk thoracic surgery patients in order to determine the incidence of myocardial injury after noncardiac surgery (MINS) as well as its link with perioperative variables, and its prognostic implications for 30-day mortality. Diagnostic criteria for MINS was seen in 48 patients (27.3%) of overall 177 included. Independent risk factors for MINS were smoker status and type of surgery, as revealed in multivariate logistic regression analysis. Following thoracic surgery, an elevated incidence of MINS was reported. MINS was found to be independently related to the extent of lung resection, but it did not relate to greater mortality. These findings indicate the possible contribution of nonischemic causes to the rise in troponin following thoracic surgeries.
