Influence of Cardiopulmonary Rehabilitation on Cardiorespiratory Adaptation in Patients With Pulmonary Hypertension

Pulmonary hypertension is a progressive disease associated with reduced exercise capacity, respiratory muscle weakness, and impaired quality of life. Exercise training and respiratory muscle training have been shown to improve physical performance and quality of life in patients with pulmonary hypertension.

forty-two medically stable patients with Group III pulmonary hypertension due to lung diseases (obstructive and restrictive) will participate in this comparative experimental study. Participants will receive cardiopulmonary rehabilitation consisting of moderate-intensity interval aerobic training and inspiratory muscle training in addition to routine medical treatment. Outcome measures will include echocardiographic parameters, pulmonary function, six-minute walk distance, estimated VO2max, dyspnea severity, and quality of life. The study aims to evaluate the influence of cardiopulmonary rehabilitation on cardiorespiratory adaptation in patients with pulmonary hypertension.

Inclusion criteria

• a)Medically stable pulmonary hypertension patients who were under optimized medical therapy. b)Pulmonary artery pressure ≥ 25 mmHg confirmed by RT side heart catheterization.

c)Forty two male patients with group 3 pulmonary hypertension (Chest cause) include Obstructive lung disease ( COPD and sleep apnea ) and restrictive lung disease (ILD). d)The patients' ages will range from 45 to 65 years old. e)BMI (25 - 34.9) kg/m2. f)World Health Organization (WHO) classification of functional classes II to III ( class II are patients with pulmonary hypertension who have a mild limitation of physical activity )(class III are patients with pulmonary hypertension who have a marked limitation of physical activity

Exclusion criteria

• g)Uncontrolled systemic HTN. h)Other types of pulmonary hypertension.. i)Smoker j)Any condition of kidney failure. k)Neurological or musculoskeletal conditions that interfere with gait

l)Impaired vision and/or hearing.

m)Patients who are unable to follow verbal instructions. n)acute exacerbation condition. o)unstable angina, serious cardiac dysrhythmias on resting ECG.
