Sir, Many studies have shown that comorbidity with regard to chronic obstructive pulmonary disease (COPD) and coronary artery disease (CAD) exists at different rates; and that especially, they share a common risk factor, namely, cigarette smoking.[1] COPD and CAD comorbidity affects quality of life and increases mortality.[2] The incidence and prevalence of CAD are increasing in the developing world.[3] This is caused by the rapid socioeconomic growth in developing countries, increasing exposure to risk factors for CAD, such as diabetes, hypercholesterolemia, hypertension and smoking.[3] In the developed world, COPD affects more than 1 in 20 of the adult population; and over the next few years, COPD is projected to be the third leading cause of death.[4] Little is known about the epidemiology of COPD in the developing world; in fact, there is hardly any published work in relation to this. The present study was designed to estimate the prevalence of COPD in patients with catheter-diagnosed CAD, and to describe factors that may increase the likelihood of COPD and CAD comorbidity in Sudan — a developing-world country. This is a cross-sectional study that included all consecutive adults with catheter-diagnosed CAD recruited from 2 cardiac centers in Khartoum, Sudan — Sudan Heart Centre and Elshaab Teaching Hospital — during a 6-month period starting August 2008. Ethical approval for the study was obtained from the administrative and ethical committee of Sudan Heart Centre, and all patients gave informed consent to take part in the study. All patients were interviewed and basic demographic data was collected. Patients performed spirometry using an electronic spirometer: Spida 5, Micromedical, England. The maneuver was explained to each subject, and the best of three readings was recorded. Height was measured to the nearest centimeter, and weight was recorded to the nearest kilogram. Predicted values were calculated as those for Blacks. Study diagnoses were based on guidelines developed by the Global Initi
