“…The high reperfusion rates, especially in the second study, are in accordance with the results of Ganz et al [7] who found evidence for early reperfusion in 78 of 81 consecutive patients using a comparable treatment regi men (750,000 -1,500,000 U SK in 15-30 min). Hoffmann et al [13], using the same dose of BRL 26921, found reperfusion of the coronary vessels in 11 of 13 patients within 5-60 min. However, in studies with immediate coronary angiography, the rate of patency ranged from 44 to 62%, when 0.7-1.5 X 106 U SK were given within 44-85 min [3,4,10].…”
