A Simplified Diagnostic and Therapeutic Approach to Pulmonary Hypertension

Pulmonary hypertension remains a common but complex disorder that physicians face in their daily practice. Pulmonary hypertension has been classified by the World Health Organization into five major categories according to etiology, pathophysiology, and hemodynamic properties. The clinical course and overall prognosis varies by etiology, therefore making the correct diagnosis is paramount to avoid delay in treatment and improve outcomes. This review aims to provide clinicians with a simplified diagnostic approach to pulmonary hypertension. We also provide a guide to risk stratification and when to refer patient to a pulmonary hypertension expert center.
