Current practice and recommendation for presurgical cardiac evaluation in patients undergoing noncardiac surgeries

Area of Science:

• Cardiology
• Perioperative Medicine
• Cardiac Surgery

Background:

• Increasing numbers of patients with coronary artery disease (CAD) require major noncardiac surgery.
• Inadequate preoperative cardiac assessment increases perioperative risks and potential complications.
• Guidelines for preoperative cardiac evaluation are essential for managing CAD patients undergoing noncardiac procedures.

Purpose of the Study:

• To provide a comprehensive algorithm for preoperative assessment of patients undergoing noncardiac surgery.
• To emphasize the role of myocardial perfusion imaging in risk stratification.
• To guide clinicians in evaluating CAD severity, stability, and perioperative risk.

Main Methods:

• Review of current guidelines and literature on preoperative cardiac evaluation.
• Development of a risk stratification algorithm for noncardiac surgery patients.
• Highlighting the utility of myocardial perfusion imaging in assessing cardiac risk.

Main Results:

• Coronary events create high-risk (6 weeks) and intermediate-risk (3 months) periods for noncardiac surgery.
• Delaying surgery is often unwarranted when it is the primary treatment.
• Myocardial perfusion imaging is a key tool for accurate risk stratification.

Conclusions:

• A structured preoperative assessment algorithm is vital for patients with CAD undergoing noncardiac surgery.
• Myocardial perfusion imaging significantly enhances the ability to stratify perioperative cardiac risk.
• Optimizing preoperative cardiac evaluation can mitigate risks and improve outcomes.
