At 2 years , a composite end point of all-cause death , any myocardial infarction , and target vessel revascularization occurred in 36.9 % for PF-PES and 16.3 % for PB-PES ( P = 0.004 ) , mainly driven by a higher rate of target vessel revascularization ( PF-PES : 35.7 % ; PB-PES : 13.8 % ; P = 0.001 ) .
