Abstract

BACKGROUND AND PURPOSE: ECP (eosinophil cationic protein) is a marker of eosinophil activity and degranulation, which has been linked to atherosclerosis and cardiovascular disease. We examined the relationship between ECP, carotid plaque, and incidence of stroke in a prospective population-based cohort.

METHODS: The subjects participated in the Malmö Diet and Cancer Study between 1991 and 1994. A total of 4706 subjects with no history of stroke were included (40% men; mean age, 57.5 years). Carotid plaque was determined by B-mode ultrasound of the right carotid artery. Incidence of stroke was followed up during a mean period of 16.5 years in relation to plasma ECP levels.

RESULTS: Subjects in the third tertile (versus first... (More)

BACKGROUND AND PURPOSE: ECP (eosinophil cationic protein) is a marker of eosinophil activity and degranulation, which has been linked to atherosclerosis and cardiovascular disease. We examined the relationship between ECP, carotid plaque, and incidence of stroke in a prospective population-based cohort.

METHODS: The subjects participated in the Malmö Diet and Cancer Study between 1991 and 1994. A total of 4706 subjects with no history of stroke were included (40% men; mean age, 57.5 years). Carotid plaque was determined by B-mode ultrasound of the right carotid artery. Incidence of stroke was followed up during a mean period of 16.5 years in relation to plasma ECP levels.

RESULTS: Subjects in the third tertile (versus first tertile) of ECP tended to have higher prevalence of carotid plaque (odds ratio: 1.18; 95% confidence interval: 1.003-1.39; P=0.044 after multivariate adjustments). A total of 258 subjects were diagnosed with ischemic stroke (IS) during follow-up. ECP was associated with increased incidence of IS after risk factor adjustment (hazard ratio, 1.57; 95% confidence interval: 1.13-2.18; for third versus first tertile; P=0.007). High ECP was associated with increased risk of IS in subjects with carotid plaque. The risk factor-adjusted hazard ratio for IS was 1.86 (95% confidence interval: 1.32-2.63) in subjects with carotid plaque and ECP in the top tertile, compared with those without plaque and ECP in the first or second tertiles.

CONCLUSIONS: High ECP is associated with increased incidence of IS. The association between ECP and IS was also present in the subgroup with carotid plaque.
