Occurrences of the combined clinical outcome measure ( cardiac death , myocardial infarction , and target vessel revascularization ; 6 % vs. 8 % ; hazard ratio [ HR ] : 0.76 ; 95 % CI : 0.26 to 2.18 , p = 0.6 ) and the need for target vessel revascularization ( 2 % vs. 6 % ; HR : 0.32 : 95 % CI : 0.07 to 1.59 , p = 0.17 ) were similar in the 2 groups .
