Preop Investigations

  • Measure preop brain natriuretic peptide (BNP) or NT-proBNP to enhance periop cardiac risk estimation in:

    • ≥65 yrs

    • 45-64 yrs w/ sig CVS dz

    • RCRI ≥1

        BNP ≥92 mg/L or NT-proBNP ≥300 ng/L a/w ↑ risk of death or MI 30 days post-noncardiac sx

 

 

 

 

 

 

  • No routine echo, coronary CTA, exercise or cardiopulmonary exercise testing, or pharmacological stress echo or radionuclide imaging

    • Urgent echo if suspected undiagnosed severe obstructive intracardiac abnormality or severe pHTN

    • Consider echo if suspect cardiomyopathy (may be reasonable to do postop)

 

  • No preop prophylactic coronary revascularization for pts w/ stable CAD undergoing noncardiac sx
