Pulmonary Artery Hypertension
Conditions
Brief summary
This study investigated the effect of 12 weeks of aerobic training on sleep quality and aerobic fitness in patients with Pulmonary arterial hypertension(PAH).
Detailed description
Thirty male PAH patients were included in the study. They were randomized into two equal groups; Training group (A) and Control group(B). Right ventricular systolic pressure (RVSP) measured using Doppler Echocardiography , Pittsburg sleep quality index (PSQI) questionnaire with the wrist worn actigraph used for the assessment of sleep disturbance, and Cardiopulmonary exercise testing (CPET) measurements included maximal heart rate and VO2max .All were measured before and after the study period for both groups.The training was a moderate intensity aerobic training on a bicycle ergometer (corresponding to 60% to 70% of the maximal heart rate they reach during peak oxygen uptake in the initial exercise test) for 30 to 45 min/day, 3 sessions/week for 12 weeks (36 sessions).
Interventions
The exercise program consisted of 5 minutes warm-up, 15-30 minutes of moderate aerobic exercises and 10 minutes cool-down, respectively. Frequency: 3 sessions/week , and Duration:12 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pulmonary artery systolic pressure (PASP) | change from baseline at 12 weeks | Pulsed Doppler Echocardiogram for assessing PASP as calculated from the gradient across the tricuspid valve using the modified Bernoulli equation. |
| Subjective self-report questionnaire that assesses sleep quality | change from baseline at 12 weeks | The Pittsburgh Sleep Quality Index is a subjective self-report questionnaire that assesses sleep quality over a 1-month time interval in different populations It is 5 points score (0 means normal, 5 means severe sleep disturbance) |
| Determining sleep patterns | change from baseline at 12 weeks | Determining sleep patterns by using actigraph to assess suspected certain sleep disorders, |
| Measuring aerobic fitness | change from baseline at 12 weeks | Level of aerobic fitness assessed by using Cardiopulmonary exercise testing (CPET) through incremental exercise intensity until voluntary exhaustion. |
