Background:The current European guidelines recommend that a preoperative electrocardiogram (ECG) should be performed routinely in patients scheduled for high-risk surgery. However, the evidence regarding ECG as a predictor of perioperative cardiac complications is weak.
Aim:To evaluate the association of preoperative ECG with short-and long-term outcomes in patients undergoing high-risk vascular procedures.Methods: This was a substudy of the international Vascular events In noncardiac Surgery patIents cohort evaluatioN (VISION) Study and included consecutive patients undergoing vascular procedures in a single tertiary center. In each patient, a preoperative 12-lead ECG was evaluated by two experienced clinicians following the Polish Cardiac Society recommendations. We performed routine perioperative troponin monitoring at five time points (one preoperative and four postoperative measurements) to evaluate whether preoperative ECG abnormalities are associated with myocardial injury after noncardiac surgery (MINS) and 1-year major adverse cardiovascular events (MACE) including cardiac death, myocardial infarction, and stroke.
Results:The study group comprised 348 patients, 80.5% of whom were male and the median age (interquartile range [IQR]) was 65 (59-72) years. The incidence of MINS and 1-year MACE was 18.7% and 14.4%, respectively. Multivariable analysis showed that none of the predefined ECG abnormalities (ST depression, left axis deviation, atrial fibrillation, and bundle branch block) was associated with the incidence of MINS or 1-year MACE.
Conclusion:This study confirmed that preoperative ECG abnormalities are frequent in patients undergoing high-risk vascular surgery. However, we did not find evidence supporting the relation between preoperative ECG abnormalities and postoperative adverse cardiac outcomes in high-risk patients.

After removal of artefacts, the mean monitoring time was 22 h08 (8 h54). All patients had impaired cerebral autoregulation during their monitoring time. The mean IAR index was 17 (9.5) %. During H 0 H 6 and H 18 H 24 , the majority of our patients; respectively 53 and 71 % had an IAR index > 10 %. Conclusion According to our data, patients with septic shock had impaired cerebral autoregulation within the first 24 hours of their admission in the ICU. In our patients, we described a variability of distribution of impaired autoregulation according to time.
