Abstract
Abstract Chronic obstructive pulmonary disease (COPD) defined by irreversible airflow obstruction and Coronary heart disease are widespread worldwide and frequently associated. However, the prevalence of COPD taking into account its severity in the coronary is still poorly known. The objective of the study was to determine the state of respiratory function of stable coronaries. Methods The descriptive prospective cross-sectional study included patients of both sexes, regardless of age, with coronary artery disease documented by positive coronary angiography, without known Obstructive Ventilatory Disorder. Patients recruited at the liberal consultation of the city of Constantine between June 2016 and August 2017 answered a questionnaire inspired by that of the American Thoracic Society (ATS) and benefited from a spirometric exploration with bronchodilator reversibility test. The diagnosis of COPD and the degree of bronchial obstruction are based on the criteria of GOLD (Global initiative for chronic obstructive lung disease). Exploration was carried out according to ATS/ERS guidelines. Results A total of 146 coronaries were included, only 117 subjects were able to perform actionable spirometry. Others were excluded for poor cooperation. 81.2% of participants were male. The mean age was 62 ± 9 years. 78.7% of subjects were smokers or ex-smokers. 17.1% had a post-bronchodilator FEV1/CV < 70% meeting the definition of COPD. 25% of the subjects were at stage 1 of the disease, 70% at stage 2 while 5% were at stage 3. There were no patients at severity stage 4. Subjects with COPD were older, they had more comorbidity and multi-stroke coronary involvement. Conclusion Coronary heart disease has a pronounced risk of COPD. COPD is often asymptomatic and remains undiagnosed. Therefore, the systematic assessment by spirometry of respiratory function provides information on the existence and severity of COPD and coronary artery disease, which would be necessary for the monitoring and management of these patients.
