Rise and fall of preoperative coronary revascularization

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Anesthesiology

Background:

• Millions of major surgeries occur globally, with a significant number in the US.
• Postoperative myocardial infarction leads to higher mortality.
• Preoperative cardiac evaluations and revascularization are sometimes used to mitigate risks.

Purpose of the Study:

• To review the literature on elective preoperative coronary revascularization before noncardiac surgery.
• To assess the efficacy of prophylactic revascularization in reducing postoperative cardiac events.

Main Methods:

• Systematic review of relevant articles published over the last 50 years.
• Analysis of studies focusing on coronary revascularization prior to noncardiac procedures.

Main Results:

• Early studies explored preemptive revascularization for reducing cardiac events.
• More recent studies indicate routine prophylactic revascularization does not decrease postoperative complications in stable coronary artery disease patients.

Conclusions:

• The benefit of routine prophylactic coronary revascularization before noncardiac surgery is not supported by current evidence for stable coronary artery disease.
• Individualized patient assessment remains crucial for perioperative cardiac risk management.
