Abstract

Introduction and objectives

Intensive glucose control with insulin in patients with an acute coronary syndrome reduces platelet reactivity during hospitalization, compared to conventional control. However, the effect of strict, long-term glucose control on platelet reactivity in these patients remains uncertain.

Methods

This is a prospective, randomized trial evaluating the effects of optimized glucose control (target glucose, 80-120 mg/dL) with insulin, compared with conventional control (target glucose, <180 mg/dL), on platelet reactivity after hospital discharge in patients with an acute coronary syndrome and hyperglycemia. The primary endpoint was assessment of platelet aggregation after stimulation with adenosine diphosphate 20 μM at 12-month follow-up.

Results

One hundred four patients were randomized to optimized management (n=53) or conventional management (n=51). There were no differences between groups in baseline characteristics or platelet function. After 12 months of follow-up, blood glucose levels were significantly lower in the optimized treatment group (104 vs 119 mg/dL; P<.001). However, platelet aggregation following adenosine diphosphate 20 μM stimulation showed no differences between the groups (54.2% [14.3%] vs 55.1% [18.3%] respectively; P=.81). There were no significant differences for other platelet function tests.

Conclusions

Long-term optimized glucose control with insulin in patients with an acute coronary syndrome did not result in a reduction in platelet reactivity compared to conventional control.
