RESOLUTE US – Diabetics
• Patients with diabetes have significantly higher
event rates because of:
– Endothelial dysfunction
– Impaired platelet function
– Altered coagulation / fibrinolysis
– Increased smooth muscle cell proliferation
• The ResoluteTM ZES is the only DES with an FDA
approved indication for patients who have coronary
artery disease and diabetes
• This post-hoc analysis reports the performance of
the ResoluteTM stent in the RESOLUTE US trial in
patients with diabetes
• Furthermore, these data are placed in context to the
larger dataset from the RESOLUTE Pooled clinical
program

RESOLUTE US & Pooled Diabetics
• In this post-hoc analysis, the RESOLUTE US trial
showed very good outcomes in the diabetic
subgroup, despite the higher risk nature of the
diabetic patient population
• There was a low rate of TLF (10.8%) and TLR
(6.7%)
• No stent thrombosis out to 3 years
