CVD-10y-postop: Long Term Cardiovascular Disease Event Risk for Patients Undergoing Major Non-Cardiac Surgery
Study Details
Study Description
Brief Summary
The goal of this observational study is to learn whether the healthy lifestyle choices made around surgery can influence an individual's long term risk of developing cardiovascular disease. Patients will be observed 1-month prior to and 3-months following surgery to assess their risk of developing cardiovascular disease.

Detailed Description
Patients who experience a medical event are often motivated to improve their health by engaging in healthy lifestyle behaviors, such as improving their diet and beginning to exercise. For example, patients who are considered smokers prior to surgery may sometimes stop smoking following surgery. However, we are unsure of other changes following surgery. For example, we are unsure if surgery can initiate any changes in exercise and diet, and we are unsure if these changes can influence the risk of developing cardiovascular disease. Consistent and positive lifestyle changes will likely reduce an individual's risk of developing cardiovascular disease in the long term.

Outcome Measures
Primary Outcome Measures
- Baseline assessment for calculating the pre-operative 10-year CVD event risk [1 month before surgery]
For the baseline assessment, the expected 10-year CVD event risk of each participant will be calculated according to the appropriate CVD event risk prediction score using blood tests, questionnaire to estimate an individual's functional capacity, blood pressure, heart rate and ECG.
- Follow-up assessment for calculating the post-operative 10-year CVD event risk [3 months after surgery]
For the follow-up assessment, the expected 10-year CVD event risk of each participant will be calculated according to the appropriate CVD event risk prediction score using blood tests, questionnaire to estimate an individual's functional capacity, blood pressure, heart rate and ECG.
Secondary Outcome Measures
- Occurrence of Cardiovascular or Non-Cardiovascular event [30 days after surgery]
Cardiovascular related (e.g. Myocardial infarction/injury, mortality, heart failure) or non-cardiovascular related (e.g. surgical site infections, unexpected critical care unit admissions, re-operations).
