Abstract

COPD is among the most common lung diseases, becoming a major health issue worldwide. Sleep disorders are frequently present in COPD patients, particularly obstructive sleep apnoea syndrome (OSAS). Patients with OSAS have increased risk of mortality due to cardiovascular events. Methodology: The study was carried out in the Department of respiratory Medicine of a tertiary health care hospital. Duration of the study was from December 2017 to November 2019. 105 study subjects were included in the study. Careful history taking and detail clinical examination was done. Patients with COPD fulfilling inclusion criteria were included in the study, all the clinical data was collected and tabulated. All the patients were evaluated with spirometry and polysomnography for detection of obstructive sleep apnea. Result: Most of the study subjects i.e. 38.09% were from age group 51-60 followed by 28.58% in more than 61 years of age group. The prevalence of OSAS in COPD (i.e. overlap syndrome) amongst study group was 27.62%. According to GOLD COPD stage, it was found that about half of the study subjects (47.63%) were at stage IV followed by 38.09 % in stage III. Only 3.81 % were at stage I. While comparing between patients suffering only from COPD and patients with overlap syndrome it was found that, at stage IV more number of people were from overlap group (68.97%) as compared to only COPD patients. The association between the two groups with stage of COPD were found to be significant. Conclusion: COPD patient’s particularly overweight and obese individuals are at greater risk of having OSAS. Polysomnography in COPD patients can prove to be useful for early detection of OSAS and to prevent them from further complications.
