lüll Diagnosis and management of pulmonary hypertension in systemic sclerosis Sweiss NJ; Hushaw L; Thenappan T; Sawaqed R; Machado RF; Patel AR; Gomberg-Maitland M; Husain AN; Archer SLCurr Rheumatol Rep 2010[Feb]; 12 (1): 8-18Patients with systemic sclerosis (SSc) can develop pulmonary hypertension (PH; mean pulmonary artery pressure >/= 25 mm Hg) caused by pulmonary arterial hypertension (PAH), left ventricular disease, or pulmonary fibrosis. PAH is a pulmonary vascular disease, the diagnosis of which requires pulmonary capillary wedge pressure less than 15 mm Hg, pulmonary vascular resistance greater than 3 Wood Units, and exclusion of thromboembolism and parenchymal lung disease. Molecular mechanisms underlying PAH-SSc include activation of inflammatory and fibrogenic pathways in the vasculature and right ventricle. Circulating autoantibodies trigger endothelial damage and fibroblast activation. PAH most commonly occurs as a late complication in patients with limited cutaneous disease and anticentromere antibodies. Although echocardiography is a useful screening tool, heart catheterization is required to diagnose PAH before initiating therapy. Prognosis and therapeutic response are worse in PAH-SSc than in other PAH categories (median survival, 1-3 y). Approved therapies include prostacyclins, endothelin antagonists, and phosphodiesterase type 5 inhibitors. Research is needed to define disease mechanisms and develop effective therapies.|Antihypertensive Agents/*therapeutic use[MESH]|Exercise Test[MESH]|Humans[MESH]|Hypertension, Pulmonary/diagnostic imaging/*drug therapy/*etiology[MESH]|Scleroderma, Systemic/*complications[MESH]|Ultrasonography[MESH] |
