Bossaert et al used a noninvasive score for determining if reperfusion was achieved following thrombolysis in a patient with an acute myocardial infarction. The authors are from the University of Antwerp in Belgium.
Parameters:
(1) change in chest pain
(2) change in ST segments
(3) reperfusion arrhythmia
Parameter
Finding
Points
chest pain change
no reperfusion (continued)
0
possible reperfusion
1
reperfusion (resolution of chest pain)
2
ST segment change
no reperfusion (unchanged or increased)
0
possible reperfusion
1
reperfusion (decreased)
2

absent
0
present

total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score 6
• The higher the score the more likely reperfusion has occurred.
