Properly diagnosing pulmonary arterial hypertension

Area of Science:

• Cardiology
• Pulmonology
• Internal Medicine

Background:

• Pulmonary hypertension (PH) significantly increases morbidity and mortality.
• Pulmonary arterial hypertension (PAH) is a specific type of precapillary PH.
• Accurate diagnosis and classification of PH are crucial for patient management.

Purpose of the Study:

• To present a diagnostic algorithm for evaluating patients with suspected PH.
• To differentiate between various clinical PH groups, particularly PAH Group 1.
• To guide clinicians in identifying risk factors and specific etiologies of PH.

Main Methods:

• Systematic review of diagnostic investigations for PH.
• Development of a detailed clinical algorithm for PH categorization.
• Inclusion of case studies for differential diagnosis and management strategies.

Main Results:

• The algorithm facilitates the confirmation of PH diagnosis and determination of its clinical group.
• It aids in identifying etiologies associated with PAH Group 1 versus other PH groups.
• The approach helps in assessing functional and hemodynamic impairment and risk stratification.

Conclusions:

• A structured algorithmic approach is essential for accurate PH diagnosis and classification.
• Differentiating PAH Group 1 from other PH groups is critical for targeted therapy.
• Comprehensive evaluation, including risk factor identification, is necessary for optimal PH management.
