Background:
The role of tight glycemic control in the management of acute ischemic stroke remains uncertain.
Objective:
Our goal is to evaluate the effects of tight glucose control with insulin therapy after acute ischemic stroke.
Methods:
We searched PubMed, CENTRAL, and EMBASE for randomized controlled trials (RCTs) that evaluated the effects of tight glycemic control (70 - 135 mg/dL) in acute ischemic stroke. Analysis was performed using fixed- and random-effects models. Outcomes were death, independence and modified Rankin Scale (mRS) score at ≥90 days follow-up, and symptomatic or severe hypoglycemia during treatment.
Results:
Twelve RCTs including 2,734 patients were included. When compared to conventional therapy or placebo, tight glycemic control was associated with similar rates of mortality at ≥90 days follow-up (pooled odds ratio [pOR], 0.99 [95% CI, 0.79 - 1.22], I
2
0%), independence at ≥90 days follow-up (pOR, 0.95 [0.79 - 1.14], I
2
0%) and mRS scores at ≥90 days follow-up (standardized mean difference, 0.014 [-0.15 - 0.17], I
2
0%). In contrast, tight glycemic control was associated with increased rates of symptomatic or severe hypoglycemia during treatment (pOR 5.2 [1.87 - 14.42], I
2
20%).
Conclusion:
Tight glucose control after acute ischemic stroke is not associated with improvements in mortality, independence or mRS score and leads to higher rates of symptomatic or severe hypoglycemia.
