[Diagnosis and treatment of pulmonary hypertension]

Abstract

Pulmonary arterial hypertension is an idiopathic process or can be associated with another circumstances (connective tissue diseases, congenital heart disease, portal hypertension, exposure to appetite suppressants or another drugs or infectious agents such as HIV). Most patients are diagnosed as the result of an evaluation of symptoms, whereas others are diagnosed incidentally or during screening of asymptomatic populations at risk. We reviews systematic screening for the approach to diagnosing pulmonary arterial hypertension. A diagnostic algorithm can guide the evaluation but it can be modified according to specific clinical circumstances. The number of therapeutic options has increased.in the last years. We reviews the use of calcium-channel blockers, prostacyclin (and analogues), endothelin-receptor antagonists, and phosphodiesterase-5 inhibitors, and the use of combination therapy, and provides specific recommendations about the actual treatment.
