Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
