Abstract

Background: Associations of three markers of thrombotic tendency, von Willebrand factor, tissue plasminogen activator antigen and fibrin D-dimer, with coronary heart disease have been reported in meta-analyses. It is not known, however, whether findings are generalizable to older women. Design: Prospective cohort of 3582 women aged 60-79 years randomly selected from 23 towns without evidence of cardiovascular disease at entry into the British Women's Heart and Health Study. Methods: Women were followed for 4.7 years for incident coronary heart disease. Cox proportional hazard models were used to compare the hazard ratio of coronary heart disease per doubling for each thrombotic factor. Results: In models adjusting for age and town only there was no association between von Willebrand factor or D-dimer and incidence of coronary heart disease, but there was a positive association of tissue plasminogen activator: coronary heart disease hazard ratio per doubling was 1.37 (95% confidence interval: 1.08-1.75). Adjustment for potential confounders (socio-economic position, smoking, lung function, physical activity, alcohol consumption, body mass index, waist-to-hip ratio) attenuated association to 1.20 (0.92-1.58). Further adjustment for risk factors that may be part of the same pathophysiological process linking tissue plasminogen activator to coronary heart disease (high density lipoprotein cholesterol, triglycerides, blood pressure, fasting glucose, insulin, C-reactive protein, fibrinogen) attenuated the hazard ratio to 1.05 (0.79-1.40). Conclusion: In older women, tissue plasminogen activator was associated with incident coronary heart disease, but does not appear to be an independent risk factor for coronary heart disease as the association was attenuated by adjustment for confounding and other metabolic and vascular risk factors.
