Uchoa RB, et al. - Researchers undertook this prospective cohort analysis to examine the link between rise in troponin I and morbidity as well as mortality following one year in patients undergoing lung resection surgery. Participants were 151 consecutive patients in total who were subjected to elective lung resection procedures, employing conventional and video-assisted thoracoscopic techniques, at a University Hospital in Brazil, from July 2012 to November 2015. Applying the American College of Physicians and the Society of Cardiology of the state of São Paulo scoring systems, preoperative risk stratification was carried out. In this patient population, with a low risk of complications as per the preoperative assessment scores, an increase in mortality within one year was reported in correlation with a rise in troponin I levels above 0.16 ng/ml in the first postoperative period.
