Perioperative Complications Linked to COVID-19 History in Elective Cardiac Surgery Patients

Study Overview
=================
Brief Summary
-----------------
A. Primary objective Identifying risk factors for peri-operative complications in patients who have had COVID-19. B. Secondary objectives Identifying peri-operative complications in patients who have had COVID-19. Follow-up of peri-operative complications during hospitalization. Identifying the safe distance at which a patient can be operated after a Sars CoV2 infection without having an increased risk of peri-operative complications. C. Study inclusion and exclusion criteria Inclusion criteria Patients should be included if: are scheduled for elective cardiac surgery with extracorporeal circulation (bypass); they give their consent for their data to be included in studies; Exclusion criteria Patients should be excluded if: they have emergency surgery; have had Sars Cov 2 infection more recently than 3 months; D. Data Collection It is done in an excel table. Data collection is done anonymously. No patient-identifying data will be collected. The collected data will be about comorbidities, COVID-19 status - disease and vaccination, postoperative complications.
