Summary

High plasma level of von Willebrand factor (VWF) is a marker of future cardiovascular events in patients at high risk of coronary artery disease (CAD). The purpose of this study was to examine the changes and the prognostic value of plasma VWF-cleaving protease (ADAMTS13) levels in patients with CAD. Plasma VWF and ADAMTS13 levels were measured in 225 patients with CAD (152 men and 73 women, age, 70.3 ± 8.9 years, mean ± SD) and 100 patients without CAD who were ageand gender-matched to the CAD patients (60 men and 40 women, age, 68.6 ± 8.9 years). The CAD patients had higher VWF and lower ADAMTS13 antigen levels compared to patients without CAD. During 22.3 ± 10.4 months follow-up period, 20 major adverse cardiac and cerebrovascular events (MACCE) occurred in 222 patients with CAD who could be followed up. Kaplan-Meier analysis demonstrated that CAD patients with high plasma VWF antigen levels were significantly more likely to develop MACCE. Furthermore, eight cardiac and cerebrovascular thrombotic events [acute coronary syndrome (n=4) and cerebral infarction (n=4)] occurred in CAD patients with both high plasma VWF and low ADAMTS13 antigen levels. Multivariate Cox hazards regression analysis identified high plasma VWF and low ADAMTS13 antigen levels as significant and independent predictors of future MACCE and thrombotic events during the follow-up period in CAD patients. Our findings suggest that low plasma ADAMTS13 as well as high VWF level is a useful predictor of cardiac and cerebrovascular events in CAD patients.
