The rates of cardiovascular death ( 3.1 % with thrombectomy vs. 3.5 % with PCI alone ; hazard ratio , 0.90 ; 95 % CI , 0.73 to 1.12 ; P = 0.34 ) and the primary outcome plus stent thrombosis or target-vessel revascularization ( 9.9 % vs. 9.8 % ; hazard ratio , 1.00 ; 95 % CI , 0.89 to 1.14 ; P = 0.95 ) were also similar .
