Pulmonary hypertension (PH) is a spectrum of diseases involving the pulmonary vascular circuit and is defined as an elevation in pulmonary arterial pressures. PH is an uncommon disorder that presents with nonspecific complaints. There remains a significant delay in the diagnosis of PH and initiation of appropriate therapy because often patients are misdiagnosed with more common causes of dyspnea such as obstructive lung diseases like asthma. The diagnosis of PH should be considered in patients who do not fit the usual profile of patients presenting with dyspnea and asthma, especially if they do not respond to therapy. The finding of PH foreshadows a poor outcome if not discovered early and treated aggressively.
