Beta Blocker Use in Cardiac Surgery and Association With Postoperative Course

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to describe in a cohort of cardiac surgery patients the use of beta-blockers before surgery and their maintenance or withdraw according to international recommendations in order to compare patients who receive a beta-blocker with maintenance during the surgical period (international recommendation) to those for whom prescription and maintenance are not respected. Patients are treated according to standard practice and this protocol does not change patient management. No additional information or data is required by the study other than the data usually collected in the patient record (drug treatment, medical history, operating data, postoperative data, complications, length of stay). The objectives of this research are : To evaluate the proportion of patients receiving beta-blocker treatment prior to cardiac surgery. To evaluate the proportion of patients receiving beta-blocker treatment before cardiac surgery and complying with international recommendations for its maintenance/stop in perioperative cardiac surgery. To evaluate the incidence of complications and length of hospital stay in patients receiving beta-blockers based on compliance or non-compliance with recommendations.
