Background: Pulmonary hypertension has been known as a rather serious condition as it affects the right side of the heart and eventually results in severe pulmonary conditions. The pulmonary arteries tend to become thick and inelastic. The functioning of the pulmonary system impairs and affects the oxygenation of the entire body. Objective: To determine the effects of pulmonary rehabilitation on endurance and quality of life in patients with pulmonary rehabilitation. Methods: Our current study is a randomized controlled trial. A purposive sampling technique was employed for sampling and 49 patients were randomly allocated into each group by lottery method. This trial was conducted at Bajwa Hospital, Shahdhrah, Lahore, Pakistan. The already diagnosed patients with pulmonary hypertension, employing World Health Organization with functional class II-IV were recruited in this study. The patients with heart failure NYHA class III and IV, mitral stenosis and systemic sclerosis were excluded from the study. The 6-minute walk test for endurance, Duke Activity Status Index for activity status and short form 36 for assessing quality of life were employed in the study. Results: The results of our study show that there is a significant difference between the groups pre and post-intervention. The majority of the data showed a p-value less than 0.05 so this indicates that data is not normally distributed and a non-parametric Mann-Whitney U test was applied between Groups 1 and 2 analysis for a 6-minute walk test. Both groups' baseline median for the 6-minute walk test had a p-value of 0.357 whereas for the 6-week median, the p-value was 0.000 which represents a statistical difference between the groups after the application of 6 weeks training program and medical treatment. Mann-Whitney U test was applied between Groups 1 and 2 analysis for Duke Activity Status Index score pre and post-intervention. Conclusion: This concluded that pulmonary rehabilitation significantly improves endurance, emotional well-being, general health, activity status and quality of life among patients with pulmonary hypertension.
