Evolution of Exercise Training in Patients with Pulmonary Hypertension-A Comprehensive Review

Area of Science:

• Cardiology
• Pulmonary Medicine
• Exercise Physiology

Background:

• Pulmonary hypertension (PH) is a severe condition with high morbidity and mortality.
• Current treatments improve management but therapeutic challenges remain across all PH groups.
• Historically, exercise was contraindicated due to safety concerns.

Purpose of the Study:

• To review the pathophysiology and current therapeutic approaches for PH.
• To summarize the beneficial physiological adaptations to exercise training in PH.
• To inform exercise specialists on integrating exercise-based rehabilitation into PH patient care.

Main Methods:

• Descriptive review of existing literature.
• Analysis of randomized trials and meta-analyses on exercise interventions in PH.
• Summary of guideline recommendations for exercise in PH.

Main Results:

• Supervised exercise training demonstrates safety and efficacy in PH patients.
• Significant improvements observed in 6-minute walk distance, peak oxygen uptake, and quality of life.
• Positive physiological adaptations include improved cardiac function, endothelial function, and muscle performance.
• Low incidence of adverse events reported with structured training programs.

Conclusions:

• Exercise training offers significant benefits for patients with pulmonary hypertension.
• Supervised exercise should be integrated into pulmonary rehabilitation as an adjunct to pharmacotherapy.
• Addressing barriers like patient fear and limited access is crucial for wider implementation.
