Abstract:
0.05 ) within 4 hours of occlusion. The minimum DA%s after occlusion were 22.19 ? 6.21 , 16.26 ? 3.88 , 6.24 ? 2.48 , 7.97 ? 2.78 and 8.80 ? 3.45 at the time instances of occlusion,1,2,3,and 4 hours after occlusion,respectively. The minimum DA%s were related to the infarcted area (IA) in the pathology within 2-4 hours of occlusion,with the values of r equal to 0.76 , 0.80 ,and 0.85 ,respectively. Conclusions Within the different time intervals after the LAD were occluded,the maximum DA%s have no significant difference,however the minimum DA%s change and relate to the IA% after 2 hours of occlusion.
