Preoperative evaluation and treatment of stable CAD in patients scheduled for major elective vascular surgery

Area of Science:

• Cardiovascular Medicine
• Surgical Oncology
• Vascular Surgery

Background:

• Controversy exists regarding the extent of preoperative cardiac evaluation for major elective noncardiac operations.
• Patients undergoing surgery for aortic aneurysms or lower limb ischemia face high risks of postoperative cardiac complications due to prevalent coronary artery disease and procedural hemodynamic stress.

Purpose of the Study:

• To evaluate the necessity and impact of preoperative cardiac studies and interventions in patients undergoing major elective noncardiac surgery.
• To determine optimal strategies for managing cardiac risk in patients with coronary artery disease undergoing non-cardiac procedures.

Main Methods:

• Review of clinical guidelines and evidence regarding preoperative cardiac assessment.
• Analysis of outcomes associated with coronary angiography and revascularization (coronary artery bypass graft surgery or percutaneous coronary interventions) prior to non-cardiac surgery.

Main Results:

• Preoperative coronary angiography is indicated only for patients with unstable cardiac conditions or significant functional limitations.
• Coronary revascularization in minimally symptomatic patients does not enhance short-term or long-term survival and postpones essential non-cardiac operations.

Conclusions:

• Preoperative coronary angiography should be judiciously applied, reserved for select high-risk individuals.
• Routine coronary revascularization before major non-cardiac surgery in asymptomatic or minimally symptomatic patients is not recommended and may be detrimental.
