Introduction: End stage liver disease and its complications are a leading cause of mortality among adults. One of the grave complications amongst numerous pulmonary afflictions in patients of end stage liver disease with portal hypertension is pulmonary hypertension. Its occurrence marks dismal prognosis. However, with better understanding of underlying pathogenetic mechanisms, early diagnosis can be achieved and which also helps in paving a way for novel therapeutics. Aims: i) To evaluate the occurrence of pulmonary hypertension in patients of cirrhosis of liver with portal hypertension. ii) To associate occurrence of pulmonary hypertension with severity of cirrhosis of liver. Methods: A cross sectional study was conducted on eighty patients with liver cirrhosis without intrinsic cardiopulmonary disease. After a detailed history, all patients were subjected to thorough clinical examination, laboratory investigations, radiological investigations including abdominal ultrasound with portal vein Doppler study, chest X -ray, ECG and transthoracic 2D ECHO. The patients were also graded for severity of liver disease using Child Pugh Score. Results: The study showed a male predominance with increased male to female ratio. And most of the patients belonged to lower socioeconomic strata. The occurrence of portopulmonary hypertension in cirrhotic patients was found in 12.5%. The presence of pulmonary hypertension was found to be increased in patients with advanced liver disease, severity as obtained by Child Pugh Score. Conclusion: There is significant occurrence of portopulmonary hypertension in patients of liver cirrhosis and also that it is associated with the severity of liver disease in exponential manner. The early identification of pulmonary hypertension is crucial in view of prognosis and helps in guiding future management by speeding up orthotopic liver transplantation.
