Pulmonary Hypertension Symptoms

Medically reviewed by Min Clinic Staff | Updated: January 2026

Pulmonary hypertension is elevated pressure in the pulmonary circulation (the arteries that carry blood from the right ventricle of the heart to the lungs to receive oxygen).

Signs and symptoms of pulmonary hypertension include shortness of breath, fast heart rate, rapid breathing, dizziness, fatigue, and difficulty breathing with exertion, leading to an inability to exercise. Other associated symptoms can include a chronic cough, chest pain, and a sensation of chest pressure.

Causes of pulmonary hypertension

Pulmonary hypertension may occur without apparent cause or it may be due to other conditions. Conditions that can cause pulmonary hypertension include certain medications, lupus, infections, liver disease, diseases of the heart valves, blood clots in the lung, and chronic obstructive pulmonary disease (COPD).
