Clinical classification of pulmonary hypertension

Area of Science:

• Cardiology
• Pulmonology
• Pathophysiology

Background:

• Pulmonary hypertension (PH) is a widespread condition with diverse causes.
• Previous classification systems, primarily based on autopsy morphology, have had limited success.
• Advances in PH treatment and prevention necessitate a revised classification.

Purpose of the Study:

• To trace the historical development of understanding pulmonary hypertension.
• To introduce a new clinical classification for pulmonary hypertensive diseases.
• To align classification with current and future treatment and prevention strategies.

Main Methods:

• Review of historical literature on pulmonary hypertension nomenclature and classification.
• Analysis of recent advancements in medical and surgical interventions for PH.
• Development of a clinically oriented classification system.

Main Results:

• Past classification efforts based on morphology proved insufficient.
• Recent therapeutic progress highlights the need for a functional classification.
• A new clinical classification is proposed, integrating etiological and therapeutic insights.

Conclusions:

• The evolution of understanding PH has led to a more practical clinical classification.
• This new classification facilitates targeted prevention and treatment strategies.
• It supports the integration of recent medical and surgical advances in managing PH.
