The relationships of carotid arthroscleroses with coronary artery stenosis in candidates for angiography

Background: Coronary artery and carotid stenosis risk factors are frequently common in these two problems. The present study was aimed to determine the relationships between carotid arthroscleroses and coronary artery stenosis in candidates for cardiovascular angiography.

Methods: In a cross sectional study, 218 candidates for cardiovascular angiography, visiting Imam Ali hospital of Kermanshah, were divided into two groups of case (158 subjects) and control (60 subjects) and were investigated by angiography and Doppler echo. Data were analyzed by Chi-square test (χ2) and multiple logistic regressions.

Results: Totally, 47 subjects (21.6%) had carotid stenosis with >50% plaque. The frequencies of this value in the case and control groups were 37 (23.4%) and 10 (16.7%) cases, respectively, indicating no significant difference between groups (P=0.27). There was a significant association between coronary artery and carotid stenosis, and female gender (P=0.008). However, no significant correlation was observed between smoking and history of hypertension in terms of age (P<0.05).

Conclusion: There was no significant association between coronary artery and carotid stenosis occurrence. However, among independent risk factors, only females had an effective role in their co-occurrence. Therefore, considering the females with coronary artery or carotid stenosis and conducting preventive measures are recommended to prevent co-occurrence of these two problems.
