The revised cardiac risk index counts six predictors of cardiac complications around noncardiac surgery.
| Input | What it means |
|---|---|
| History of cerebrovascular disease? | Use the observed finding or laboratory value for this criterion, following the definition shown in the form. |
| History of congestive heart failure? | Use the observed finding or laboratory value for this criterion, following the definition shown in the form. |
| History of ischemic heart disease? | Use the observed finding or laboratory value for this criterion, following the definition shown in the form. |
| Pre-surgery creatinine level >2 mg/dL (176.8 µmol/L)? | The laboratory creatinine concentration; mg/dL and µmol/L need different numeric values. |
| Pre-surgery treatment with insulin? | Fasting insulin concentration for indices that require a fasting sample. |
| High risk noncardiac surgery? | Use the observed finding or laboratory value for this criterion, following the definition shown in the form. |
A history of ischemic heart disease plus insulin treatment gives 2 points if other predictors are absent.
Use the calculation to make the method and its inputs easier to check with a healthcare professional. Its meaning depends on the clinical setting and on whether the underlying method is appropriate for that person.
No. It describes a calculation or score from the supplied information. A qualified clinician must check the measurements, the method’s applicability and the wider clinical picture.
Use the units specified in the form and select a conversion only where the page provides one. Different substances need different conversion factors; a mismatch can produce a plausible but incorrect result.
