Background: Pulmonary arterial hypertension (PAH) is a complication of chronic obstructive pulmonary disease (COPD) in advanced stages, and its presence indicates a poor prognosis. Aim of the study: The study aimed to find out the Prevalence of Pulmonary Artery Hypertension and its Correlation with the Severity of Bronchiectasis in a Tertiary Care Hospital. Methods: In this observational cross-sectional study we enrolled and analyzed 34 patients. The study was considered at the department of Cardiology, at Khulna Medical College and Hospital, Khulna, Bangladesh. The analysis was performed on patients who were admitted with chronic lung disease and the study duration was one year from June 2021 to July 2022. Result: The prevalence and severity of pulmonary hypertension; more than 60% of patients had pulmonary hypertension, and 40% had no complications (Table 2). According to comorbidities, 34 patients have diabetes, and 24 suffer from hypertension (Table 3). The echo findings of the study population are based on Pulmonary artery pressure (N=13), TAPSE (N=8) and FAC (N=13). Conclusion: 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.
