Perioperative dynamics of highly sensitive troponin I in patients operated on the ascending and aortic arch. A comparative prospective study

Introduction. Patients with thoracic aortic pathology are one of the most difficult categories of patients, however, the informative value of high-sensitive troponin I during reconstruction of thoracic aorta needs to be investigated further.Aim. To determine the correlation between the high-sensitive troponin I and risk of postoperative complications in patients operated on thoracic aorta.Methods. A prospective observational single-center study, which included patients operated on the ascending aorta and aortic arch. Blood samples were taken for troponin I before the induction of anesthesia, at the end of the operation and 6 hours after the end.Results. The study included 112 patients, 58 of them underwent surgery on ascending aorta and 54 on aortic arch. Correlation between growth of highly sensitive troponin I was observed with time of artificial circulation, myocardial ischemia both at the end of the operation (R = 0,4 p
