BACKGROUND: Aortic aneurysms are associated with coronary artery ectasia (CAE). However, the relation between the extent of CAE and the severity of aortic dilatation is not understood. This study was undertaken to investigate the relationship between angiographic extension of CAE and aortic dimension. PATIENTS AND METHODS: We retrospectively include 135 patients with angiographic diagnosis of CAE defined as dilatation of coronary segment more than 1.5 times than an adjacent healthy one. Study population was divided in four groups according to the maximum diameter of ascending aorta beyond sinus of Valsalva obtained in the parasternal long-axis view (group 1: <40 mm; group 2: 40-45 mm; group 3: 45-55 mm; group 4: >55 mm or previous surgery because of aortic aneurysm/dissection). The relationship between aortic dimension and the extension of CAE was investigated by means of multivariable linear regression, including variables selected at univariable analysis (P < 0.1). The total estimated ectatic area (EEA total) was used as dependent variable. RESULTS: Baseline characteristics of study groups were well balanced. Patients in group 4 were more likely to have both higher neutrophil count and neutrophil to lymphocyte ratio. On univariable analysis ascending aorta diameter [Coef. = 0.075; 95% confidence interval (CI) 0.052-0.103, P < 0.01] and c-reactive protein (CRP) values [Coef. = 0.033, 95% CI 0.003-0.174, P = 0.04] showed a linear association with total EEA. After adjustment for CRP values only the ascending aorta diameter was still associated with the extent of CAE (95% CI 0.025-0.063, P < 0.01). CONCLUSION: In patients with diagnosis of CAE, a strong linear association between aortic dimension and coronary ectasia extent exists.

Abstract

BACKGROUND: Aortic aneurysms are associated with coronary artery ectasia (CAE). However, the relation between the extent of CAE and the severity of aortic dilatation is not understood. This study was undertaken to investigate the relationship between angiographic extension of CAE and aortic dimension. PATIENTS AND METHODS: We retrospectively include 135 patients with angiographic diagnosis of CAE defined as dilatation of coronary segment more than 1.5 times than an adjacent healthy one. Study population was divided in four groups according to the maximum diameter of ascending aorta beyond sinus of Valsalva obtained in the parasternal long-axis view (group 1: <40 mm; group 2: 40-45 mm; group 3: 45-55 mm; group 4: >55 mm or previous surgery because of aortic aneurysm/dissection). The relationship between aortic dimension and the extension of CAE was investigated by means of multivariable linear regression, including variables selected at univariable analysis (P < 0.1). The total estimated ectatic area (EEA total) was used as dependent variable. RESULTS: Baseline characteristics of study groups were well balanced. Patients in group 4 were more likely to have both higher neutrophil count and neutrophil to lymphocyte ratio. On univariable analysis ascending aorta diameter [Coef. = 0.075; 95% confidence interval (CI) 0.052-0.103, P < 0.01] and c-reactive protein (CRP) values [Coef. = 0.033, 95% CI 0.003-0.174, P = 0.04] showed a linear association with total EEA. After adjustment for CRP values only the ascending aorta diameter was still associated with the extent of CAE (95% CI 0.025-0.063, P < 0.01). CONCLUSION: In patients with diagnosis of CAE, a strong linear association between aortic dimension and coronary ectasia extent exists.
