[Preoperative evaluation and management of patients with ischemic heart disease undergoing noncardiac surgery]

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Anesthesiology

Context:

• Increasing prevalence of coronary artery disease (CAD) in aging populations presents challenges for noncardiac surgery.
• Current management of CAD includes medical therapy, percutaneous coronary intervention (PCI) with stents, and coronary artery bypass grafting.
• Drug-eluting stents (DES) pose risks of late stent thrombosis if antiplatelet therapy is discontinued before noncardiac surgery.

Purpose:

• To evaluate management strategies for patients with CAD undergoing noncardiac surgery.
• To explore the role of off-pump coronary artery bypass (OPCAB) in this patient population.

Summary:

• Off-pump coronary artery bypass (OPCAB) is a safe and effective revascularization technique that avoids cardiopulmonary bypass.
• OPCAB can be performed simultaneously or staged with noncardiac procedures like carotid endarterectomy or aortic aneurysm resection.
• This approach mitigates risks associated with prolonged antiplatelet therapy after PCI, particularly with drug-eluting stents.

Impact:

• OPCAB presents a viable and promising option for patients with both CAD and noncardiac disease requiring surgical intervention.
• Improved management strategies can reduce perioperative cardiac events and optimize surgical outcomes.
• This facilitates timely noncardiac procedures for patients with complex cardiovascular conditions.
