Background: Pulmonary artery hypertension (PAH) dreadful complication in bronchiectasis. The 6th world symposium on pulmonary hypertension have taken mPAP of 20 mmHg as normal. Not much studies have been done based on the current cut off values, so we have incorporated values based on the new guidelines and made following observations.

Methods: This study was designed as an observational cross-sectional study consisting of 27 patients, who were admitted in Pulmonary medicine department.

Results: Out of 27 study subjects 15 were female’s and 12 were males. It was found that 70.3% had less than 5 segments involved and 29.6% had more than 5 segments involved. Mean value of PAH was 34.48±18.06 mmHg. Analysis showed a significant correlation (r=0.67) between number of segments involved and incidence of pulmonary hypertension.

Conclusions: It is essential to evaluate the cardiac status of bronchiectasis patients at the time of diagnosis as cardiac manifestations are one of the dreadful complications.
