Predicting Cerebrovascular Adverse Events Post Cardiac Surgery

The aims of this study are: i) to assess cerebral autoregulation and autonomic control within the different phases of cardiac surgery with cardiopulmonary bypass; ii) to compare cerebral autoregulation measures derived via cerebral blood flow velocity estimated by transcranial Doppler device with simpler measurements derived from near infrared spectroscopy; iii) to develop a predictive model of postoperative cerebrovascular outcome (overt or silent stroke) based on the extracted indices.
