Thrombolysis – The use of thrombolytic agents to
restore coronary permeability significantly reduces mortality
in AMI 49,50. Reperfusion, when instituted early, limits
myocardial damage, improves ventricular function and
promotes electrical stability. Late reperfusion may also be
beneficial, favoring ventricular scaring and remodeling.
The thrombolytic agent and the way it is administered
seem to be important in reducing cases of cardiogenic
shock. ISIS-3 study, which compared the administration of
three agents (streptokinase, t-PA and APSAC), did not
show any difference among them in reducing cases of
cardiogenic shock 51. However, in the GUSTO study 52,
where t-PA was administered using a faster infusion, a
greater speed in coronary reperfusion rates was obtained,
probably resulting in a smaller incidence of cardiogenic
shock (5.1% x 6.6%, p
