Background Known risk factors for intracerebral hemorrhage (ICH) include age, hypertension, smoking, alcohol intake, and anticoagulant use. Some previous reports have indicated that hemostatic factors measured many years before the onset of ICH might predict the later occurrence of ICH. The objective of this analysis was to test whether selected hemostatic factors measured years before the onset of ICH could identify patients at higher risk for future ICH. Methods We performed a nested case-control study within the Women's Health Initiative (WHI) cohort. Postmenopausal women aged 50-79 years (mean 68) at baseline (1993-1998) were enrolled at 40 Clinical Centers in the United States and followed for adjudicated ICH for a mean of 11.4 years. ICH cases (N = 75) and controls (N = 75) were matched on age, ethnicity, blood pressure, anticoagulant use, and treated hypertension. Stored blood samples from the baseline WHI examination were tested for von Willebrand factor (vWF), a disintegrin-like and metalloprotease domain with thrombospondin type-1 motif, number 13 (ADAMTS13), tissue plasminogen activator (t-PA), and urokinase plasminogen activator (u-PA). Platelet count, white blood cell count, and hemoglobin concentration were also measured. Results Mean baseline levels of vWF (1.03 and.95 U/mL), ADAMTS13 (1.0 and 1.1 μg/mL), vWF: ADAMTS13 ratio (.99 and.92), t-PA (14.75 and 14.80 IU/mL), and u-PA (.09 and.10 IU/mL) were not significantly different by case-control status. Significant differences were also not identified for platelet count, hemoglobin, white blood count, or reported alcohol use. Conclusion None of the 4 baseline hemostatic factors nor the platelet count was predictive of future ICH risk in this long-term study of older postmenopausal women.
