ASSENT 4 • Mulitcentric randomized trial comparing two strategies in acute myocardial • “Facilitated PCI” : TNK followed by immediate angiography/ angioplasty (1 to 3 hours) versus primary PTCA
ASSENT 4 • 4000 pts with large MI • Study stopped after inclusion of 1667
Comparison of outcomes in ASSENT-4 with those in other trials of TNK in MI patients
