ADAMTS13 deficiency promotes acute myocardial I/R injury. (A) Representative triphenyl-2,3,4-tetrazolium-chloride–stained heart sections from one mouse of each genotype after 30 minutes of ischemia and 23.5 hours of reperfusion injury. The infarcted area is white. (B) Quantification of the infarct size (n = 7-10/group). Each dot represents a single mouse. Horizontal bars indicate mean values. (C) Plasma cardiac TnT levels (n = 7-10 /group). Data are means ± SEM.
