title: Pulmonary Hypertension: Diagnosis and Treatment.
abstract: Pulmonary hypertension is a common, complex group of disorders that result from different pathophysiologic mechanisms but are all defined by a mean pulmonary arterial pressure of 25 mm Hg or greater. Patients often initially present to family physicians; however, because the symptoms are typically nonspecific or easily attributable to comorbid conditions, diagnosis can be challenging and requires a stepwise evaluation. There is limited evidence to support screening of asymptomatic individuals. Echocardiography is recommended as the initial step in the evaluation of patients with suspected pulmonary hypertension. A definitive diagnosis cannot be made on echocardiographic abnormalities alone, and some patients require invasive evaluation by right heart catheterization. For certain categories of pulmonary hypertension, particularly pulmonary arterial hypertension, treatment options are rapidly evolving, and early diagnosis and prompt referral to an expert center are critical to ensure the best prognosis. There are no directed therapies for many other categories of pulmonary hypertension; therefore, family physicians have a central role in managing contributing comorbidities. Other important considerations for patients with pulmonary hypertension include influenza and pneumonia immunizations, contraception counseling, preoperative assessment, and mental health.
