title: [Acute myocardial infarction with shock. Intracoronary thrombolysis].
abstract: Of 932 pts with acute myocardial infarction (AMI) who underwent reperfusion therapy (RT) by intracoronary streptokinase (IC.STK), 32 pts had cardiogenic shock (CS). Shock was defined as systolic blood pressure (BP) < or = 80 mmHg without inotropic support or BP < or = 90 mmHg with inotropic or balloon counterpulsation support and left ventricular end diastolic pressure < 18 mmHg and clinical symptoms of hypoperfusion. Time from onset of symptoms to initiation of therapy was less than 6 hours. Reperfusion was defined as reestablishment of antegrade TIMI-2 or 3 flow in occluded artery. Comparison revealed no significant differences in sex, age, time after onset of symptoms, artery involved, history of previous AMI, left ventricular ejection fraction and in extent of coronary disease between pts with successful and failed thrombolysis. IC.STK was successful in 12 pts with CS (37.5%) and in 67.2% of pts without CS (p < or = 0.001). Mortality rate in pts with CS was 25% in reperfused and 81.8% among nonreperfused (p = 0.0095).
  
  
  CONCLUSIONS
  1. IC.STK gives a considerably lower rate of reperfusion in pts with AMI complicated by CS. 2. No influence on the frequency of effective reperfusion with respect to the analyzed clinical and angiographical data was found. 3. The high mortality in the group with unsuccessful reperfusion as well as the low effectiveness of the IC STK indicates the necessity to apply more effective methods of reperfusion in pts with AMI complicated by CS.
