Association between Carotid and Coronary Artery Disease in Patients with Aortic Valve Stenosis: An Angiographic Study

Abstract

Background Patients with aortic stenosis have a high prevalence of coronary artery disease, but there is little information about the association of coronary artery disease and carotid artery disease. Methods The study includes 317 consecutive patients with aortic stenosis, who underwent carotid and coronary angiography during the same catheterization before aortic valve replacement. Results At univariate analysis, the prevalence of coronary artery disease was associated with (1) presence of carotid artery disease ( P < .001); (2) angina pectoris as presentation symptom ( P < .001); (3) age more than 65 years ( P < .05); and (4) hypertension ( P < .05). At multivariate analysis, only carotid artery disease, angina, and age emerged as independent predictors of coronary artery disease. The combination of 2 variables (carotid artery disease, angina) allowed the identification of 4 groups, with decreasing prevalence of coronary artery disease: (1) angina+/carotid artery disease+: 85%; (2) angina—/ carotid artery disease+: 50%; (3) angina+/carotid artery disease—: 41%; (4) angina—/carotid artery disease—: 21% ( P < .001). Conclusion In patients with symptomatic aortic stenosis, the presence of significant carotid artery disease is a strong marker of significant coronary artery disease.
