[BDSP. Notice produite par INIST akrR0x6D. Diffusion soumise à autorisation]. Established risk factors cannot explain all the variance in coronary heart disease (CHD). Immunoglobin E (IgE), a mediator of allergy, can affect platelets and arterial smooth muscle. We previously demonstrated a cross-sectional association between IgE and cardiovascular disease (CVD) in men. The present study evaluated this relationship prospectively in 278 men and 343 women followed for a mean of 8.9 years. There was an association between IgE and coronary disease in men, but not in women. There was no association for CVD, stroke, or all-cause mortality. The age-adjusted relative risk (RR) for coronary mortality in men with baseline IgE 200 kU/L was 1.66 (p 0.66), but for nonfatal myocardial infarction (MI) it was 6.46 (p 0.01). This association was independent of smoking and other risk factors, and unrelated to allergy. Thus, elevated IgE was a strong independent prospective risk factor for nonfatal, but not fatal, MI in men.
