Title: Evaluation and Monitoring of Perioperative Management of Patients With Coronary Stents Undergoing Noncardiac Surgery
Brief Summary: The purpose of this study is to evaluate and monitor perioperative management of patients with coronary stents undergoing noncardiac surgery.

Objectives:

* To describe the incidence and severity of adverse cardiovascular events in patients with coronary stents undergoing noncardiac surgery with admission.
* To assess the following-up of the guidelines about the perioperative management of antiplatelet therapy in these patients.
* To assess the relationship between the incidence of cardiac or neurovascular events, as well as bleeding complications with the perioperative management of antiplatelet therapy.
* Number of Participants with Adverse Events as a Measure of Safety


Options:
A: Inclusion criteria

* ≥ 18 years old
* Surgery within 72 hours of an acute admission to the Department of Surgery or an acute reoperation.
* Major gastrointestinal surgery on the gastrointestinal tract. This will include
* Open, laparoscopic, or laparoscopically-assisted procedures
* Procedures involving the stomach, small or large bowel, or rectum for conditions such as perforation, ischaemia, abdominal abscess, bleeding or obstruction
* Washout/evacuation of intra-peritoneal abscess (unless due to appendicitis or cholecystitis - excluded, see below)
* Washout/evacuation of intra-peritoneal hematoma
* Bowel resection/repair due to incarcerated umbilical, inguinal and femoral hernias (but not hernia repair without bowel resection/repair)
* Bowel resection/repair due to obstructing/incarcerated incisional hernias provided the presentation and findings were acute
* Laparotomy/laparoscopy with inoperable pathology (e.g. peritoneal/hepatic metastases)
* Laparoscopic/Open Adhesiolysis
* Return to theatre for repair of fascial dehiscence
* Any reoperation/return to theatre meeting the criteria above is included

If multiple procedures (primary surgery or reoperation) are performed on different anatomical sites within the abdominal/pelvic cavity, the patient would be included if the major procedure is general surgical.

Exclusion criteria

* Not capable of giving informed consent after oral and written information
* Previously included in the trial
* If transferred directly from the operation room or recovery ward to the intensive care unit
* Elective laparoscopy
* Diagnostic laparotomy/laparoscopy where no subsequent procedure is performed (NB, if no procedure is performed because of inoperable pathology, then include)
* Appendectomy +/- drainage of localized collection unless the procedure is incidental to a non-elective procedure on the GI tract
* Cholecystectomy +/- drainage of localized collection unless the procedure is incidental to a non-elective procedure on the GI tract (All surgery involving the appendix or gallbladder, including any surgery relating to complications such as abscess or bile leak is excluded)
* Non-elective hernia repair without bowel resection.
* Minor abdominal wound dehiscence unless this causes bowel complications requiring resection
* Ruptured ectopic pregnancy, or pelvic abscesses due to pelvic inflammatory disease
* Laparotomy/laparoscopy for pathology caused by blunt or penetrating trauma
* Laparotomy/laparoscopy for esophageal pathology Laparotomy/laparoscopy for pathology of the spleen, renal tract, kidneys, liver, gall bladder and biliary tree, pancreas or urinary tract
B: Inclusion Criteria:

* Surgical and procedural patients who require anesthesia services

Exclusion Criteria:

* Patients under the age of 18 years
C: Inclusion criteria

* Patients received a perioperative hs-cTnT screening for PMI
* Patient consent available Exclusion criteria
* Patient's refusal
D: Inclusion Criteria:

* \> 18 years old, with coronary stents
* American Society of Anaesthesia physical status II-V
* noncardiac surgery wiht admission
* informed consent

Exclusion Criteria:

* \< 18 years old
* American Society of Anaesthesia physical status I
* ambulatory surgery
* pregnancy
* obstetric anaesthesia
* endoscopic procedures
* cardiac surgery
* not informed consent
