Vascular Events In Patients Undergoing Same-day Noncardiac Surgery (VALIANCE) Study
Vascular Events In Patients Undergoing Same-day Noncardiac Surgery (VALIANCE) Study - A Prospective Observational Cohort Study Evaluating Major Cardiovascular and Adverse Events in Patients Undergoing Elective Same-day Noncardiac Surgery
Source: ClinicalTrials.gov · Last updated 4 Nov 2026
Brief summary (registry, in English)
The proportion of noncardiac surgeries performed as same-day surgery is increasing worldwide, with more complex surgeries being performed on higher risk patients in the outpatient setting. Little is known on the risk factors, incidence and prognosis of patients undergoing same-day noncardiac surgery. The main objective of this study is to inform on the incidence and risk factors of cardiovascular and other adverse events after same-day surgery and to develop risk prediction tools to better inform on the risk and selection of patients undergoing same-day surgery.
