Australian surgical outcomes examination of vascular events in non-cardiac surgery patIents cohort evaluation (AUSSIE VISION)

This study is a prospective cohort study that will provide information about the risk of having a cardiovascular event such as a heart attack or stroke or other major medical adverse outcomes after non-cardiac surgery in Australians.


AUSSIE VISION aims to determine the incidence of major cardiovascular events such as heart attack and stroke after non-cardiac surgery and contribute to development of an optimal clinical risk prediction model to predict major cardiovascular events after surgery.


AUSSIE VISION is a prospective cohort study of 3000 patients undergoing major non-cardiac surgery. Inclusion criteria are patients 45 years and older having a major non-cardiac operation (defined as an operation requiring an overnight stay in hospital). All patients will have post-operative troponin testing to assess whether they have had a heart attack associated with their operation. Follow-up of major cardiovascular events and other major events including death and re-hopsitalisation will continue for one year after the operation.

AUSSIE VISION is part of a larger international collaborative effort to study cardiovascular events after non-cardiac surgery. The international collaborative study called VISION currently involves investigators from 13 countries (Australia, Brazil, Canada, China, Colombia, India, Italy, Malaysia, Poland, South Africa, Spain, United Kingdom and United States) targeting approximately 40, 000 patients in total.
