title: Optimal management of severe pulmonary arterial hypertension.
abstract: Over the past decade, awareness among the medical profession of pulmonary arterial hypertension (PAH) being a treatable disease has increased. Despite this, approximately one-fifth of newly diagnosed patients are classified as being in the most severely compromised functional class (i.e. New York Health Association/World Health Organization functional class (NYHA/WHO FC) IV). The prognosis for patients in NYHA/WHO FC IV is poor, with 3-yr survival being around 40%, even with treatment. Poor prognosis coupled with severe functional impairment means it is vital that these patients receive optimal treatment. There are also subgroups of patients, who, although classified as NYHA/WHO FC III, may actually be severely haemodynamically compromised and at risk of rapid deterioration. Such subgroups include patients with PAH associated with systemic sclerosis or certain heritable mutations. These patients should be considered as being at the more severe end of the disease spectrum. In this article we will discuss the optimal management of patients with severe PAH. This includes newly emerging evidence from small-scale, open-label studies that use upfront combination therapy with intravenous epoprostenol plus oral PAH-specific drugs. We also review treatment strategies that may offer clinical benefits to patients with more severe PAH.
