Coronary angiography in 506 patients with extracranial cerebrovascular disease

Area of Science:

• Cardiology
• Neurology
• Vascular Surgery

Background:

• Extracranial cerebrovascular disease evaluation often involves patients with concurrent coronary artery disease.
• Identifying patients at risk for perioperative cardiac events is crucial for surgical planning and outcomes.

Purpose of the Study:

• To assess the prevalence of coronary artery disease (CAD) in patients undergoing evaluation for extracranial cerebrovascular disease.
• To develop a perioperative cardiac screening algorithm to mitigate myocardial infarction (MI) risk in patients requiring extracranial reconstruction.

Main Methods:

• Prospective evaluation of 506 patients (mean age 65) with extracranial cerebrovascular disease.
• Coronary angiography performed on patients with prior neurologic symptoms or asymptomatic carotid bruits.
• Comparison of CAD prevalence based on clinical suspicion versus actual findings.

Main Results:

• Severe, surgically correctable CAD found in 37% of patients with clinical suspicion versus 16% without.
• Severe inoperable CAD identified in 9.8% and 1.5% of respective groups.
• Higher prevalence of severe inoperable CAD (14%) observed in diabetic patients.

Conclusions:

• A significant proportion of patients with extracranial cerebrovascular disease have underlying severe CAD.
• A novel algorithm for perioperative cardiac screening can aid in risk stratification.
• Implementing this algorithm may reduce perioperative MI and improve outcomes in patients undergoing vascular reconstruction.
