Quality of life in ambulatory pulmonary arterial hypertension in connective tissue diseases and its relationship with risk stratification.

ABSTRACT: The Pulmonary Arterial Hypertension Symptoms and Impact Questionnaire (PAH-SYMPACT) is a PAH-specific patient-reported outcome scale assessing patients' quality of life from four aspects: cardiopulmonary symptoms, cardiovascular symptoms, physical impacts and cognitive/emotional impacts. This study aimed to validate the Chinese version of PAH-SYMPACT and explore its relationship with risk stratification in patients with connective tissue disease-associated pulmonary arterial hypertension (CTD-PAH). In addition, 75 patients with CTD-PAH confirmed by right heart catheterization were invited to complete questionnaires including PAH-SYMPACT, the 36-item Medical Outcomes Study Short Form Survey (SF-36) and EuroQol five dimensions questionnaire (EQ-5D). The demographic, clinical, laboratory and treatment data were collected. The endpoint was treatment goal achievement status in 6-12 months after completing the questionnaires, defined as an integrated outcome. Participants' mean age was 36.4 ± 11.9 years and the mean pulmonary arterial pressure was 38.9 ± 13.67 mmHg. The reliability of the PAH-SYMPACT domains ranged from 0.83 to 0.88. Results of factor analysis basically conformed the original PAH-SYMPACT. The treatment goal achievement (TGA) status in 6-12 months was significantly associated with physical impacts scores (odds ratio: 0.180, 95% confidence interval: 0.036-0.908, P=0.038). The Chinese version of PAH-SYMPACT is a reliable measurement to evaluate quality of life in CTD-PAH patients and is also a potential predictor of patient's condition change in routine clinical practice.

Project description:ObjectivesFew studies have focused on pulmonary arterial hypertension (PAH) associated with connective tissue diseases (CTDs). The optimal treatment for CTD-PAH has yet to be established.DesignMeta-analysis of the data from evaluations of treatment for PAH generally (19 studies) and CTD-PAH specifically (nine studies) to compare the effects of pulmonary vasodilative PAH agents. MEDLINE, EMBASE and BIOSIS were searched. English-language full-text articles published between January 1990 and August 2012 were eligible.SettingInternational.ParticipantsPatients with PAH generally (n=3073) and CTD-PAH specifically (n=678).Primary outcome measureExercise capacity (6 min walk distance, 6 MWD).ResultsPatients with PAH (all forms) had mean age 32-55 years (women, 61-87%); CTD-PAH patients had mean age 45-55 years (women, 74-95%). Overall estimate of mean change in 6 MWD from baseline (95% CI) for the active treatment group versus the control group in all patients with PAH was 34.6 m (27.4-41.9 m). Pooled mean differences from the results for patients receiving placebo by subgroup of patients receiving phosphodiesterase (PDE)-5 inhibitors, endothelin receptor antagonists (ERAs) and prostacyclin (PGI2) analogues were 22.4-45.5, 39.5-44.2 and 12.4-64.9 m, respectively. Overall estimate of mean difference between changes in 6 MWD in patients with CTD-PAH was 34.2 m (23.3-45.0 m). Pooled mean differences by subgroup of patients receiving PDE-5 inhibitors, ERAs and PGI2 analogues in patients with CTD-PAH were 37.0-47.1, 14.1-21.7 and 21.0-108.0 m, respectively. ERAs were less effective in patients with CTD-PAH than all-form patients with PAH: 14.1 m (-4.4-32.6 m) vs 39.5 m (19.5-59.6 m) for bosentan and 21.7 m (2.2-41.3 m) vs 44.2 m (30.2-58.2 m) for ambrisentan.ConclusionsAll three types of PAH agent are effective. However, ERAs may be a less effective choice against CTD-PAH; further studies are needed. Limitations include the limited number of studies for some agents and for patients with CTD-PAH.
