Coronary Angiography Before Elective Carotid Endarterectomy in Patients With Asymptomatic Coronary Artery Disease
Coronary Angiography Before Elective Carotid Endarterectomy in Patients With Asymptomatic Coronary Artery Disease
The purpose of this study is to evaluate the potential benefit of systematic preoperative
 coronary angiography followed by selective coronary artery revascularization on the incidence
 of myocardial infarction (MI) in patients without a history of coronary artery disease (CAD)
 and undergoing carotid endarterectomy (CEA).
Patients candidates for CEA, with no history of CAD, a normal electrocardiogram (ECG), and a
 normal cardiac ultrasound were randomized in two groups. In group A (n = 216) all patients
 underwent coronary angiography before CEA +- coronary artery revascularization. In group B (n
 = 210) CEA was performed without coronary angiography.
Inclusion Criteria:

 -  indication for carotid endarterectomy

 -  no clinical sign or history of ischemic heart disease

 -  no electrical signs of cardiac ischemia

 -  left ventricular ejection fraction >50% at transthoracic echocardiogram.

 Exclusion Criteria:

 -  disabling stroke (mRS ≥3)

 -  non atherosclerotic carotid disease

 -  severe intracranial carotid artery stenosis

 -  contra-indications to heparin, aspirin or clopidogrel.
