Prevalence of pulmonary hypertension in OSA patients with obstructive airway diseases

Abstract

The aim of this study is to study the prevalence of pulmonary hypertension in obstructive sleep apnea patients with obstructive airway disease using ECHO. Subjects and method:The study was performed on 50 obstructive airway diseases (OAD) patients out of which 35 were associated with OSA. After getting informed consent, patients basic demographic details, clinical history, detailed general and systemic examination, spirometry, sleep study, Echo were performed for each patients. Results: In our study pulmonary hypertension were higher in number in OSA patients compared to the NON-OSA patients. Among the obese patients higher number of pulmonary hypertension were observed. As far as severity is concerned more number of severe pulomonary hypertension were noted in OSA and Obese patients. Conclusion: Pulmonary hypertension is invariably present in most of the OSA patients with obstructive airway diseases. Hence control of OSA by CPAP therapy in OAD patients will prevent or delay the development of pulmonary hypertension.
