Official Title: Preoperative Heart Rate Variability and Baroreflex Sensitivity in ASO Patients During Various Sleep Stages
Brief Summary: The goal of this study is to evaluate the possible preoperative predictive value of altered heart rate variability (HRV) and baroreflex sensitivity in different sleep stages for postoperative adverse cardiac events (i.e. arrhythmia or myocardial ischemia needing hospitalization or medication, myocardial ischemia assessed by enzyme release, myocardial infarction, sudden cardiac death, stroke) in arteriosclerosis obliterans patients.
