Incidence of carotid artery atherosclerosis in patients with coronary artery disease.
The natural history of coronary artery disease (CAD) is often complicated by cerebrovascular accidents. The real incidence of atherosclerotic lesions of carotid arteries in coronary patients is not well established. In order to detect a high-risk group for stroke development, 184 patients affected by CAD, either partially symptomatic or asymptomatic for carotid artery stenosis, underwent Echo-Doppler ultrasonography (duplex scanning) of supra-aortic branches. Significant carotid stenosis (> 50%) was demonstrated in 51 subjects (27.7%); 21 subjects (41.2%) were partially symptomatic (dizziness, vertigo, lipothymia, etc), and 30 subjects (58.8%) were completely asymptomatic. The authors' data suggest that carotid disease can develop concurrently with coronary disease in a significant proportion of patients, even though completely asymptomatic. In order to obtain optimal long-term results, both coronary and carotid artery disease require appropriate evaluation and either medical or surgical management. For these reasons they recommend duplex scanning as a routine screening procedure in patients affected by CAD.
