VWF and coronary artery disorder: As shown in Table 4, types of coronary disease, high range of follow up sample size, patients treated with PCI, and the utilization of antiplatelet or anticoagulation were not the source of heterogeneity in vWF plasma levels examined on admission (types of coronary disease: P = 0.489; high range of follow up sample size: P = 0.364; patients treated with PCI: P = 0.725; the utilization of antiplatelet: P = 0.527; the utilization of anticoagulation drugs: P = 0.509).
