At 4 years , the rates of target lesion failure ( 15.2 % vs. 14.6 % , p = 0.68 ) , cardiac death ( 5.4 % vs. 4.7 % , p = 0.44 ) , and target vessel myocardial infarction ( 5.3 % vs. 5.4 % , p = 1.00 ) , clinically-indicated target lesion revascularization ( TLR ) ( 7.0 % vs. 6.5 % , p = 0.62 ) , and definite/probable stent thrombosis ( 2.3 % vs. 1.6 % , p = 0.23 ) were similar with the R-ZES and EES .
