600The Primary Objective is to show non inferiority in cardiac safety (i.e myocardial necrosis-MN- assessed by positive cardiac Troponin I -cTnI- ultrasensitive assay) of a Xenon based general anesthesia procedure in patients with elevated cardiac risk scheduled for atherosclerotic vascular surgery (i.e patient with Coronary Arteries Disease risk) when compared to sevoflurane based general anesthesia procedure, postoperatively up to 3 days.
The Primary endpoint is defined as an increase above the 99th percentile of highly sensitive cardiac Troponin I (cTnI) at any time during the 72 h post operatively. Time frame 3 days post-op;
Key secondary endpoint(s) are routine (Local laboratory) dosage of standard cardiac Troponin I (cTnI) at D1 (24h) and D3 (72 h) post operatively, and also in case of any suspicion of Myocardial Infarction , Routine cardiac safety monitoring.
0.8-1.1 minimum alveolar concentration (MAC) Xenon in 30 % oxygen (Group A)
0.8-1.1 Minimum Alveolar Concentration (MAC) Sevoflurane in 30 % oxygen (Group B)
Inclusion Criteria: Age ≥ 18 years Scheduled for atherosclerotic vascular elective surgery with presumed fast-track, Cardiac ischaemic risk supported by: History of myocardial infarction older than 1 month and/or Documented Stable angina (asymptomatic ± medical treatment) and/or History of coronary revascularisation, and/or Surgical Risk Index ("Lee" index) ≥ 3. Written informed consent Exclusion Criteria: Unstable angina within the last 30 days, Non controlled arterial Hypertension .
