The Diagnostic Approach to Pulmonary Hypertension

Area of Science:

• Cardiology
• Pulmonology
• Medical Diagnostics

Background:

• Pulmonary hypertension (PH) presents nonspecifically, leading to diagnostic delays.
• PH often indicates severe underlying cardiopulmonary disease.
• Accurate diagnosis is essential for identifying patients needing specific therapies for pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH).

Purpose of the Study:

• To provide an overview of strategies for the early diagnosis of PAH and CTEPH.
• To guide clinicians in differentiating and managing PH, avoiding overdiagnosis.
• To supplement existing European Society of Cardiology (ESC) and European Respiratory Society (ERS) guidelines with practical clinical insights.

Main Methods:

• Review of diagnostic strategies for pulmonary hypertension.
• Emphasis on early identification of PAH and CTEPH.
• Discussion of clinical experience in managing suspected PH cases.

Main Results:

• Despite noninvasive methods, right heart catheterization remains the gold standard for PH confirmation.
• Focus on differentiating specific PH types requiring targeted treatment.
• Strategies aim to balance early detection with avoiding unnecessary interventions.

Conclusions:

• Early and accurate diagnosis of PH, especially PAH and CTEPH, is critical for effective management.
• Clinical practice can benefit from practical approaches to guideline recommendations.
• Careful diagnostic evaluation is necessary to ensure appropriate treatment for patients with pulmonary hypertension.
