What is the most common initial symptom of pulmonary hypertension?

• A. Productive cough with purulent sputum
• B. Exertional dyspnea
• C. Hemoptysis
• D. Pleuritic chest pain

Answer: (B)

Exertional dyspnea is the most common initial symptom because pulmonary hypertension narrows the pulmonary arteries and raises vascular resistance, leaving the right heart with limited ability to increase output during exercise. When a person tries to meet higher oxygen demands, breathlessness results early, even though at rest many may still feel relatively well. As the disease advances, fatigue, lightheadedness, syncope with exertion, and eventually signs of right heart failure can develop. A productive cough with purulent sputum suggests infection or chronic lung disease rather than a primary vascular problem. Hemoptysis can occur later as pressures rise and small vessels rupture, but it’s not the typical first symptom. Pleuritic chest pain points more toward pleuritis or pulmonary embolism, rather than the early presentation of pulmonary hypertension.
