Brief Summary:
A prospective, multi-centre, observational study of preoperative natriuretic peptide testing for patients undergoing non-cardiac surgery conducted over four weeks.
Detailed Description:
Identification of high-risk surgical patients requires risk stratification. Current clinical risk stratification tools, e.g. Revised Cardiac Risk Index (RCRI), only have a moderate ability to identify these patients. International guidelines, like Canadian Cardiovascular Society on perioperative cardiovascular risk assessment, advocate that all patients 45 yrs and older or patients \>18y rs who have significant cardiovascular disease and who are coming for intermediate to high-risk surgery, should get natriuretic peptide (NP) testing. This is because raised preoperative B-type natriuretic peptides have a strong association with postoperative cardiac complications according to observational studies and meta-analyses.
However, in these patients with significant cardiovascular disease coming for intermediate to high-risk surgery it is unknown how many patients will actually have raised B-type natriuretic peptides. That is, which group of patients have an even higher risk in this already high-risk group. Natriuretic peptide (NP) testing is also expensive.
Further identification of patients that need NP testing will reduce costs and focus efforts on those patients who really need it.
