Markers of successful reperfusion from fibrinolysis in acute STEMI

Q: Out of the following which markers are preferable in to predict successful reperfusion from fibrinolysis in acute ST elevation myocardial infarction (STEMI)?

B) Myoglobin
C) Troponin
D) A and B
E) Reperfusion arrhythmias


Troponin is now treated like a holy grail in STEMI but rapidly rising and falling CK-MB or/and myoglobin are more reliable indicator of successful reperfusion after fibrinolysis in STEMI. Although reperfusion arrhythmia is common after successful fibrinolysis in acute STEMI, it is neither a sensitive nor a specific sign.
