Crest syndrome-pulmonary hypertension with little or no parenchymal lung disease is a life-threatening manifestation of the connective tissue diseases. patients with scleroderma, particularly those with crest syndrome (calcinosis, raynaud phenomenon, esophageal involvement, sclerodactyly, and telangiectasias) have a high incidence of pulmonary hypertension. the prevalence ranges from 2% to 35% in patients with scleroderma to 50% in those with crest syndrome. the prevalence in patients with other disorders varies from 23% to 53% in those with mixed connective tissue disease to 0.5% to 14% in those with systemic lupus erythematosus; it is less common in those with rheumatoid arthritis, sjogren syndrome, and dermatomyositis. treatment of pulmonary hypertension in patients with connective tissue diseases should be patterned after the protocol for ipah.
