Diagnostic strategies for suspected pulmonary arterial hypertension: A primer for the internist

ABSTRACT

Pulmonary arterial hypertension should be considered in patients who present with nonspecific symptoms such as dyspnea or dizziness after more common causes have been ruled out. Echocardiography can help in the diagnosis: special attention should be given to assess the tricuspid valve and right ventricular function. Before starting treatment, a patient should undergo right heart catheterization to accurately measure the pressures and assess right ventricular function, which help in appropriate selection of therapy.
