Usefulness of serum endothelin levels in predicting death and myocardial infarction but not coronary progression in postmenopausal women with coronary disease (from The Women's Angiographic Vitamin and Estrogen [WAVE] study)

We performed a cohort study of 392 postmenopausal women who had coronary disease to assess whether baseline serum endothelin-1 level predicts angiographic disease progression, nonfatal myocardial infarction, or death. Angiographic progression was defined as the annualized change in minimal lumen diameter of all qualifying lesions for each patient. Twenty-nine patients died or had a myocardial infarction during follow-up. Each picogram per milliliter increase in endothelin-1 was associated with a 1.8-fold increased risk of death or myocardial infarction. After adjustment for potential confounders, endothelin-1 remained a predictor of clinical events but was not correlated with angiographic progression. (c) 2005 Elsevier Inc. All rights reserved.
