VWF deficiency reduces acute myocardial I/R injury and ADAMTS13 deficiency–mediated aggravated myocardial I/R injury is VWF dependent. (A) Quantification of the infarct size (n = 7-10/group). WT and Adamts13^−/− mice are a different set of mice from those shown in Figure 1. Each dot represents a single mouse. Horizontal bars indicate mean values. (B) Plasma cardiac TnT levels (n = 7-10/group). Data are means ± SEM. NS indicates nonsignificant.
