Background: Intracellular adhesion molecule-1 (ICAM-1) regulates leukocyte-endothelial attachment, a process crucial to atherosclerosis. Circulating soluble ICAM-1 (sICAM-1) may serve as a marker of cardiovascular disease (CVD) progression. Objectives: We examined the association of sICAM-1 with measures of subclinical CVD and risk of incident CVD events and death in older men and women (age ≥65 years) from the Cardiovascular Health Study. Meth ods: Selected participants were free of clinical CVD at baseline. Nonexclusive incident case groups were angina (n = 534), myocardial infarction (n = 304), stroke (n = 327), and death (n - 842; CVD death = 310). A total 643 subjects were free of events during follow-up. Results: sICAM-1 was positively associated with C-reactive protein, interleukin-6 and fibrinogen and measures of subclinical CVD in these older men and women. In Cox regression models adjusted for age, gender, and race, increasing levels of sICAM-1 were associated with increased risk of all cause mortality in men and women. Hazard ratios (95% confidence intervals) for a one standard deviation increase in sICAM-1 (89.7 ng mL-1)) were 1.3 (1.1-1.4) in men and 1.2 (1.1-1.3) in women. sICAM-1 was associated with increased risk of CVD death in women (1.2; 1.0-1.5), but not men (1.1; 0.9-1.3). There were no associations of sICAM-1 with non-fatal CVD events. Conclusions: While sICAM-1 was associated with death in older men and women, there was a more marked association between sICAM-1 and CVD death in women.
