with occlusions exceeding 20 min there was persistence of systolic passive lengthening for 6 h despite the absence of infarction in the segment lengths in which function was being evaluated , although infarcted tissue was present ranging from 16.5 +/- 2.6 % of the area of ischemia in dogs with 60-min coronary occlusions to 37.2 +/- 4.6 % of the area of ischemia in dogs with 120-min occlusions .
