[Pulmonary arterial hypertension]

Area of Science:

• Cardiology
• Pulmonology
• Vascular Medicine

Background:

• Pulmonary arterial hypertension (PAH) is a progressive, life-threatening disorder characterized by elevated pulmonary artery pressure.
• Diagnosis is confirmed by measuring mean pulmonary artery pressure exceeding 25 mmHg at rest or 30 mmHg during exercise.

Purpose of the Study:

• To provide a comprehensive review of current knowledge on pulmonary arterial hypertension.
• To summarize clinical classification, risk factors, pathology, pathogenesis, diagnostic methods, and clinical course of PAH.

Main Methods:

• Review of existing literature on pulmonary arterial hypertension.
• Synthesis of information on current and emerging therapeutic strategies.
• Discussion of interventional procedures and combination therapies.

Main Results:

• Current treatments can reduce pulmonary pressure, alleviate symptoms, and enhance patient activity levels and survival.
• Various pharmacological agents are available, including calcium channel blockers, prostacyclin analogues, endothelin receptor antagonists, and phosphodiesterase-5 inhibitors.
• Emerging strategies and combination therapies offer new avenues for PAH management.

Conclusions:

• While no cure for PAH currently exists, specialized treatments significantly improve patient outcomes.
• A thorough understanding of PAH's multifaceted aspects is crucial for effective management.
• Ongoing research into novel therapeutic strategies holds promise for improving the prognosis of this rare disease.
