ST variability during the first 4 hours of acute myocardial infarction predicts 1-year mortality.

摘要: Background: Early and complete myocardial reperfusion is the goal when treating a patient with acute infarction. To achieve this in each individual, an on-line, accurate, easily handled preferably noninvasive technique to monitor flow alterations needed. Recurrent ST-segment elevation has been shown reflect cyclic disturbances perfusion. Methods: We have retrospectively analyzed ST variability 102 patients infarction randomized 100 mg of rt-Pa or placebo. Patients were monitored for 24 hours using vectorcardiography. Results: alive at one year (86%) had significantly less during first four hours: 4.3 versus 7.1 episodes, P = 0.007. having six more episodes showed 31.3% one-year mortality as compared no variability. Furthermore was reduced by fibrinolysis. Conclusion: detectable real time associated worse outcome. A.N.E. 2001; 6(3):198–202
