  • Title: Increased pulmonary artery pressure in association with Raynaud's phenomenon.
    Author: Ohar JM, Robichaud AM, Fowler AA, Glauser FL.
    Journal: Am J Med; 1986 Aug; 81(2):361-2. PubMed ID: 3740093.
    Abstract:
    Pulmonary artery vasospasm is a hypothesized antecedent and etiologic factor in the pulmonary hypertension associated with progressive systemic sclerosis. Recent clinical data refute the existence of pulmonary vasospasm in a cohort of patients with scleroderma and normal baseline pulmonary artery pressure. A case of episodic pulmonary hypertension associated with a digital Raynaud's response is reported, and a cardiac mechanism is hypothesized.
