Cardiac risk assessment after noncardiac surgery: a historical cohort study on guideline adherence at a Canadian quaternary care centre

CNConstantinos Dean NoutsiosMcGill University Health Centre AMAmanda MarinoMcGill University Health Centre

Key Points

Postoperative cardiac ischemia is linked to increased 30-day morbidity and mortality, highlighting the need for better risk assessment.
Only around 50% of patients had BNP screening as per CCS guidelines, while adherence for troponin and ECG was lower.
This cohort study examines guideline adherence at a Canadian quaternary care centre, emphasizing the importance of cardiac assessments.
Further investigation is required to understand the impact of increased testing on long-term outcomes and physician practices.

Abstract

About half of the patients undergoing noncardiac surgery in our cohort underwent BNP screening as recommended by CCS guidelines; troponin and ECG acquisition adherence was even lower. While postoperative cardiac ischemia is associated with increased 30-day morbidity and mortality, more studies exploring physician risk stratification practice and the impact of increased testing on long-term outcomes are needed.
