Key result
Individual elective operations exhibit a wide continuum of intrinsic perioperative cardiac risk, ranging from 0.01% for excisional breast biopsy to 4.1% for aorto-bifemoral bypass grafting.
Why the study?
Does assessing the intrinsic cardiac risk of individual operations improve upon broad categorization for preoperative cardiac risk assessment?
Observational
Yes
Does assessing the intrinsic cardiac risk of individual operations improve upon broad categorization for preoperative cardiac risk assessment?
Grouping operations into broad categories inadequately accounts for the wide continuum of intrinsic cardiac risk of individual operations, suggesting a need for procedure-specific risk assessment.
No takes yet. Share an insight, caveat, or question.
May support procedure-specific over broad-category cardiac risk assessment in elective surgery; observational data leave this hypothesis open for prospective validation.
Liu et al. (2018) conducted an observational in Elective operations. Individual elective operations vs. Broad surgical risk categories was evaluated on Composite of perioperative adverse cardiac events (cardiac arrest requiring cardiopulmonary resuscitation or acute myocardial infarction). Individual elective operations exhibit a wide continuum of intrinsic perioperative cardiac risk, ranging from 0.01% for excisional breast biopsy to 4.1% for aorto-bifemoral bypass grafting.
