Pulmonary arterial hypertension (PAH) is a rare condition causing right heart failure due to high pulmonary artery pressure. Early diagnosis via echocardiography and right-heart catheterization is crucial for effective management and improved patient outcomes.

Area of Science:

  • Cardiology
  • Pulmonology
  • Rare Diseases

Context:

  • Pulmonary arterial hypertension (PAH) is a severe condition characterized by elevated pulmonary arterial resistance, leading to right heart failure.
  • PAH can be idiopathic, familial (linked to BMPR2 mutations), or secondary to other conditions.
  • The prevalence of idiopathic PAH is approximately 2 million per year in France, with symptoms like dyspnea often leading to underdiagnosis.

Purpose:

  • To provide a comprehensive overview of Pulmonary Arterial Hypertension (PAH).
  • To outline diagnostic criteria and methods for PAH.
  • To discuss current and emerging treatment strategies for PAH.

Summary:

  • Diagnosis involves non-invasive screening with echocardiography and mandatory hemodynamic confirmation via right-heart catheterization (mean pulmonary artery pressure >25 mmHg).

  • Acute pulmonary vasodilator testing with nitric oxide or prostacyclin is recommended during catheterization.
  • Recent therapeutic advances, including prostacyclin infusions and endothelin receptor antagonists, have significantly improved patient prognosis.

    • Impact:

    • Improved understanding of PAH diagnosis and management.
    • Highlights the importance of early detection and intervention for better patient outcomes.
    • Suggests further evaluation of novel treatments like inhaled iloprost and PDE5 inhibitors, with lung transplantation as a final option.
