| pubmed-article:17296859 | pubmed:abstractText | Circulating levels of fibrinogen, fibrin D-dimer, C-reactive protein (CRP), tissue plasminogen activator antigen (t-PA) and von Willebrand factor are associated with incident coronary heart disease. We describe cross-sectional diurnal, seasonal, and blood-processing patterns for these variables, and assess whether they represent important sources of variability that should be taken into account in epidemiological studies or for additional risk prediction in individuals. | lld:pubmed |
