  1. Respiratory illness, bêta-agonists, and risk of idiopathic dilated cardiomyopathy : the Washington, DC, dilated cardiomyopathy study.

    Article - En anglais

    An epidemiologic study was carried out to examine the possible role of bêta-agonists and other respiratory medications in the development of idiopathic dilated cardiomyopathy.

    Associations with respiratory medications, bronchial asthma, emphysema, and chronic bronchitis were examined by comparing newly diagnosed cases (n=129) ascertained from five Washington, DC, area hospitals for the period 1990-1992 with neighborhood controls (n=258) identified by using a random digit dialing technique.

    The cases and controls were matched on sex and 5-year age intervals and were compared in the analysis using conditional logistic regression methods.

    A statistically significant association was observed between idiopathic dilated cardiomyopathy and history of emphysema or chronic bronchitis (adjusted odds ratio (OR)=4.4,95% confidence interval (01) 1.6-12.4).

    The association with bronchial asthma was of borderline significance (adjusted OR=1.9,95% Cl 0.9-4.2).

    Associations were also observed with use of oral bêta-agonists (adjusted OR=3.4,95% CI 1.1-11.0) and bêta-agonist inhalers or nebulization (adjusted OR=3.2,95% CI 1.4-7.1), as well as with use of oral corticosteroids, inhaled corticosteroids or cromolyn, and theophylline medications.

    The results of this study suggest, but do not prove, that use of bêta-agonists has an etiologic role in idiopathic dilated cardiomyopathy.
