Combined effects of diltiazem and oxygen in pulmonary hypertension of mixed connective tissue disease

J Rheumatol. 1994 Sep;21(9):1763-5.

Abstract

A 45-year-old woman with pulmonary hypertension and mixed connective tissue disease (MCTD) underwent right heart catheterization to evaluate the effects of vasodilators. Nasal oxygen at 2 l/min in addition to 300 mg diltiazem improved pulmonary hemodynamics without adverse effects. After 1 year of diltiazem and home oxygen, sustained favorable hemodynamic effects were obtained, which were more marked than the acute effects. We conclude that this combination may be a potent treatment for pulmonary hypertension in patients with MCTD.
