Correlation between perceived quality of life among patients with Pulmonary Arterial Hypertension, the 6-minute walking test and the risk stratification

The Pulmonary Arterial Hypertension Symptoms and Impact Questionnaire (PAH-SYMPACT) is a PAH-specific patient-reported outcome scale assessing patientsâ quality of life (QoL) 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).75 patients with CTD-PAH confirmed by right heart catheterization (RHC) 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 (TGA) status in 6-12 months after completing the questionnaires, defined as an integrated outcome. Participantsâ mean age was 36.4Â±11.9 years and the mean pulmonary arterial pressure (mPAP) was 38.9Â±13.67 mmHg. The reliability of the PAH-SYMPACT domains ranged from 0.83-0.88. Results of factor analysis basically conformed the original PAH-SYMPACT. The PGA status in 6-12 months was significantly associated with physical impacts scores (OR:0.180, 95% CI: 0.036-0.908, P=0.038). The Chinese version of PAH-SYMPACT is a reliable measurement to evaluate QoL in CTD-PAH patients and is also a potential predictors of patientâs condition change in routine clinical practice.

The Mean

Pulmonary arterial hypertension (PAH) impairs exercise tolerance and daily physical activity (PA). Aside from the hemodynamic limitations, physical, cognitive and emotional factors may play a relevant and as yet unexplored role. We investigated whether there is an association between the PA level and psychological disorders, health-related quality of life, and daily activities. We also searched for an association of the PA level with clinical factors and functional capacity. This was an analytical, cross-sectional, observational study conducted in a Brazilian University Hospital. Twenty stable PAH subjects wore an accelerometer for a week and completed an activity diary. They answered the quality of life questionnaire (SF-36), as well as the anxiety and depression scale (HADS), and the Manchester Respiratory Activities of Daily Living questionnaire (MRADL). Transthoracic echocardiography, the 6-Minute walk test (6MWT), the 1-minute sit-to-stand test (STST), and spirometry were performed. For statistical analysis we used Chi-square tests or Fisher's test as appropriate and the Mann-Whitney test to compare numerical values between two groups. The relationship between the parameters was assessed using the Spearman correlation test. The mean age was 44.3 years, 80% were women, 80% had idiopathic PAH, and 20% had connective tissue disease . The mean daily step count was 4,280 Â± 2,351, and the mean activity time was 41.6 Â± 19.3 minutes. The distance covered (6MWT) was 451.5 m, and the number of movements (1-STST) was 23.8. Thirty percent scored positive for anxiety, and 15% for depression (HADS). There was a significant correlation between accelerometer data and walking distance (6MWT), number of movements (1-STST), level of daily physical activity (MRADL), and depression symptoms. Our findings support the hypothesis that other aspects beyond physical and hemodynamic ones might impact the daily physical activity of patients with PAH.

Arginine Supplementation

Current evidence suggests that exercise training is beneficial in pulmonary arterial hypertension (PAH). Unfortunately, the standard supervised, hospital-based programs limit patient accessibility to this important intervention. Our proof-of-concept study aimed to provide insight into the usefulness of a prescribed walking regimen along with arginine supplementation to improve outcomes for patients with PAH. Twelve PAH patients (all women) in New York Heart Association (NYHA) functional class (FC) II (n = 7) or III (n = 5) and in stable condition for ≥ 3 months were enrolled. Patients performed home- and fitness-center- based walking at 65–75% heart rate (HR) reserve for 45 min, six sessions/week for 12 weeks. Concomitant L-arginine supplementation (6000 mg/day) was provided to maximize beneficial endothelial training adaptations. Cardiopulmonary exercise testing, 6-min walk testing (6MWT), echocardiography, laboratory studies, and quality of life (QoL) survey (SF-36) were performed at baseline and 12 weeks. Eleven patients completed the study (72 session adherence rate = 96 ± 3%). Objective improvement was demonstrated by the 6MWT distance (increased by 40 ± 13 m, P = 0.01), VO2max (increased by 2 ± 0.7 mL/kg/min, P = 0.02), time-to-VO2max (increased by 2.5 ± 0.6 min, P = 0.001), VO2 at anaerobic threshold (increased by 1.3 ± 0.5 mL/kg/min, P = 0.04), HR recovery (reduced by 68 ± 23% in slope, P = 0.01), and SF-36 subscales of Physical Functioning and Energy/Fatigue (increased by 70 ± 34% and 74 ± 34%, respectively, P < 0.05). No adverse events occurred, and right ventricular function and brain natriuretic peptide levels remained stable, suggesting safety of the intervention. This proof-of-concept study indicates that a simple walking regimen with arginine supplementation is a safe and efficacious intervention for clinically stable PAH patients, with gains in objective function and QoL measures. Further investigation in a randomized controlled trial is warranted.
