Cardiopulmonary Exercise Testing in Pulmonary Hypertension.

Area of Science:

• Cardiology
• Pulmonology
• Exercise Physiology

Background:

• Pulmonary arterial hypertension (PAH) is a progressive disease impacting patient quality of life, morbidity, and mortality.
• PAH involves pulmonary vascular remodeling, increased resistance, and right ventricular afterload, potentially leading to right heart failure.
• Patients experience ventilation inefficiency, high dead space, dynamic hyperinflation, and ventricular-arterial uncoupling, causing dyspnea and low exercise tolerance.

Purpose of the Study:

• To highlight the impact of PAH on patient health and exercise capacity.
• To underscore the role of cardiopulmonary exercise testing (CPET) in PAH management.

Main Methods:

• Review of existing literature on PAH pathophysiology and clinical manifestations.
• Discussion of the diagnostic and prognostic utility of CPET in PAH.

Main Results:

• PAH significantly impairs ventilation, gas exchange, and cardiac function.
• CPET provides valuable insights into disease severity and patient response to therapy.

Conclusions:

• PAH is a debilitating condition requiring accurate diagnosis and monitoring.
• CPET is an essential tool for evaluating PAH patients, guiding treatment, and differentiating from other pulmonary vascular diseases.
