RESUMEN
Objective:To explore the relationship between pulmonary function and coronary artery disease (CAD) with the severity of coronary artery lesions in relevant patients. Methods:A total of 200 patients received coronary angiography (CAG) in our hospital were studied. The patients were divided into 2 groups: Non-CAD group, n=88 and CAD group, n=112. The degree of coronary stenosis was assessed by GENSINI score;the pulmonary function, echocardiography and fasting blood level of brain natriuretic peptide(BNP) were examined in all patients. Results:Forced expiratory volume in 1 second (FEV1) in CAD group (2.33±0.54) L/1s was lower than Non-CAD group (2.63±0.39) L/1s, P=0.04. Multivariate logistic regression analysis indicated that decreased FEV1 was the independent risk factor for CAD (OR=2.9, 95%CI 1.89-4.23, P Conclusion:Decreased FEV1 is not only related to CAD occurrence, but also related to the degree of coronary stenosis in relevant patients.
