The purpose of this study is to establish a registry database for patients undergoing anesthesia for cardiovascular surgery or procedures in our operating or hybrid room. The following information will be collected:

1. Preoperative patient assessment
2. All monitored perioperative biosignal data
3. Intraoperative and immediate postoperative hemodynamic information, input/output balance, and medication usage
4. Short- and long-term prognosis from electronic medical records This database will be used to develop a vigilant monitoring system that integrates multiple biosignal data simultaneously, contributing to the improvement of anesthesia care.

Inclusion Criteria:

1. Adults age 19 and older
2. Patients scheduled for anesthesia at a cardiovascular hospital for cardiovascular surgery or procedures

Exclusion Criteria:

1) Emergency (surgery/procedure room transfer within 1 hour of visit) where there is insufficient time for the subject (adult 19 years of age or older) or his/her representative (adult incapable of consent) to decide whether to participate in the study
