- Background: Intra-individual changes in haemostatic factor concentrations over time are unknown, in the general population.Objective: To describe intra-individual longitudinal changes in tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), tPA/PAI-1 complex, von Willebrand factor (VWF), and C-reactive protein (CRP) over nine years, in different age groups, stratified for sex.Methods: The MONICA survey in 1990 examined randomly selected men and women in four age groups (25–64 years) who were re-examined in 1999. A total of 309 individuals donated venous blood samples in Stabilyte tubes for both surveys during the morning hours, after an overnight fast. We analysed tPA activity and antigens of tPA, PAI-1, tPA/PAI-1 complex, VWF, and CRP.Results: Over nine years, in both men and women, we found significant intra-individual increases in the antigen levels of tPA, PAI-1, tPA/PAI-1 complex, VWF, and CRP (P < 0.001). PAI-1 antigen levels increased by 75% for men and 95% for women. Compared to men, women had a significantly higher CRP increase (0.92 vs. 0.22 mg/L; P = 0.044). The P for trend for mean Δ1999–1990 across age groups showed a significant linear trend for VWF (P = 0.001 for men; P < 0.001 for women), but not for the other studied variables.Conclusions: There were intra-individual longitudinal increases in the antigen levels of tPA, PAI-1, tPA/PAI-1 complex, VWF, and CRP over nine years in both men and women, with PAI-1 showing the highest relative increase. VWF increased significantly across age groups; however, fibrinolytic variables did not.
