Persistent ST elevation is the general technical term for failed thrombolysis.Regression of 50% of admission ST elevation is the required criteria for susccesful thrombolysis .
Thrmobolysis fails in about 40-50% .
Main determinant is the timing of thrombolysis – not the thrombolytic agent ! do not get carried away with all those curent hoopla about Tenecteplase stuff
If we take 100 patients with persistent ST elavation 90-95 will be in anterior LAD territory .
This is a stunning a cardiology secret no book of cardiology address . . . Implication of which could be very significant . Primary PCI will always struggle to prove it’s superiority over thrombolysis in the right coronary artery .(Note LCX STEMI is different , infact it is more tricky than even even LAD .This issue will be addressed seperately in my blog.)
