In a sickle cell patient presenting with exertional dyspnea and peripheral edema, what condition is most likely occurring?

• A. Heart failure
• B. Pulmonary hypertension
• C. Chronic bronchitis
• D. Pneumonia

Answer: (B)

In a sickle cell patient presenting with exertional dyspnea and peripheral edema, pulmonary hypertension is the most likely condition occurring. Sickle cell disease is associated with various complications due to vaso-occlusive phenomena, which can lead to chronic hypoxia and damage to pulmonary vasculature over time. This damage can result in the development of pulmonary hypertension, characterized by elevated blood pressure in the pulmonary arteries. Patients with this condition may experience exertional dyspnea, which is a common symptom due to inadequate oxygenation of the blood and increased work of breathing during physical activities. Additionally, as right heart strain occurs in response to increased pulmonary pressures, peripheral edema can develop due to heart failure manifestations, but it is primarily a consequence of the pulmonary vascular changes rather than left heart failure. In contrast, heart failure generally presents with more systemic signs of fluid overload or left-sided symptoms, chronic bronchitis would typically result in productive cough along with dyspnea, and pneumonia usually presents with fever, cough, and pulmonary infiltrates on imaging. The symptom profile and the underlying pathophysiology in sickle cell disease point more clearly to pulmonary hypertension as a complication rather than the other options presented.
