Background: Elevated coronary morbidity and mortality of patients with chronic obstructive pulmonary diseases (COPD). Common intimate-media thickening (CCA-IMT) and carotid plaques are replacement markers of atherosclerosis and predictors of CV cases. Purpose and objectives: The present research aimed at assessing and evaluating the incidence of subclinical carotid atherosclerotic vascular diseases in patients with COPD Sujets and methods: a cross-sectional sample of 75 topics has been conducted; 25 stable COPD patients and 50 controls (25 patients with other chest diseases and 25 apparently healthy persons). They were divided into three groups: Group I: 25 healthy COPD patients (Global initiative for Chronic Obstructive Lung Disease Recommendations 2020 diagnosis and gravity of COPD) (GOLD 2020). Group II: 25 people and other underlying pulmonary conditions. Group III: 25 people seemingly well. The thesis lasted between 6 and 12 months Results: The prevalence of carotid disease in COPD patients was slightly higher than controls. Multinomial analyses of logistic regression have shown COPD to be an independent carotid plague indicator. Conclusion: Subclinical atherosclerosis is greatly correlated with COPD. These results will help to prepare appropriate strategies for CV prevention
