The Exercise Capacity and Quality of Life in the Patients With IPAH and Secondary PH

Overview

Pulmonary hypertension (PH) is a progressive disease with high mortality rate, but due to the development of drugs, the prognosis of the disease has improved. However patients still have poor exercise capacity and decrease of the quality of life. Past studies have shown that idiopathic and secondary PH are different in etiology and prognosis. It is necessary to further understand the difference between exercise capacity and quality of life of these two types of patients.

Background. Pulmonary hypertension (PH) is a progressive disease with high mortality rate, but due to the development of drugs, the prognosis of the disease has improved. However patients still have poor exercise capacity and decrease of the quality of life. Past studies have shown that idiopathic and secondary PH are different in etiology and prognosis. It is necessary to further understand the difference between exercise capacity and quality of life of these two types of patients. Purpose. The purpose of this study is the comparison of idiopathic and secondary PH in exercise capacity and quality of life, and analyzed the factors affecting. Method. The patients recruit from National Taiwan University hospital. Thirty patients who diagnosis with PH and willing to participant our study will recruited. According to the cause of disease patients will divided into two groups, idiopathic group and secondary PH group has fifteen patients. Both of group receive testing, including body composition, exercise capacity (six minutes walk test, cardiopulmonary exercise testing), record their regular physical activity( seven day physical activity recall questionnaire) , fatigue severity(fatigue severity scale), and quality of life (SF-36), monitor cardiac function (non-invasive cardiac output test instrument). Data are analyze using SPSS19.0 version. Data will be presented in mean ± standard deviation and percentage. Using Kolmogorov-Smirmov test to test, whether the data were normal distribution, when P\> 0.05 is considered as a normal distribution. Mann-Whitney U test or Chi-square test to processing parameters between two groups. Independent sample t test will be used to compare whether there are between-group differences. Pearson correlation coefficient will be used to test correlations between the parameters. The study defines significant level at α = 0.05, two-tailed.
