Aims&objective: To study the incidence&severity of pulmonary hypertension(PH) in tobacco and biomass related COPD patients. Materials&Methods: This was a retrospective review of in–patients with COPD either with tobacco/biomass fuel exposure. Case–records of 160 patients admitted in department of pulmonary medicine during 2017–2018 were reviewed. Elevated right ventricular systolic pressure(RVSP >25) calculated through echocardiography was taken as pulmonary–hypertension. Results&conclusion: In this study 56 outof 102 patients of tobacco exposure(55%) and 34 outof 58 patients of biomass fuel exposure(58%) had elevated RVSP. Patients exposed to cigarette smoke had less incidence of pulmonary–hypertension compared to beedi/chutta,but it was not statistically significant. We conclude that occurrence of pulmonary–hypertension is almost equal with tobacco smoke and biomass fuel exposure,but severity to biomass–smoke for >10years had high incidence of pulmonary–hypertension(76%) when compared to tobacco–smoke for >10years(48.30%) and is significant (pvalue–0.00).
