Abstract:
Symptomatic HIV-associated pulmonary artery hypertension (PHT) is a thousand times more frequent than idiopathic PHT and has a clearly worse prognosis. Using echocardiographic criteria the prevalence of PHT in HIV-positive patients, including all degrees of clinical severity, is about 7.5 %, half of those affected being asymptomatic (NYHA class I). The only available data are from just one controlled trial of drug treatment of HIV-associated PHT (BREATH-4-Trial), in which the endothelin-receptor antagonist bosentan was found to bring significant improvement in clinical parameters (NYHA functional class, walking distance). Further trials are required to test other therapeutic options such as prostanoids and phosphodiesterase-5-inhibitors.
