Interventions to rapidly normalise blood glucose inconsistently are applied and with uncertain utility. Here we review the association of hyperglycaemia with outcome, present evidence that this hyperglycaemia reflects more than a pre-existing diabetic state and discuss mechanisms by which glucose may adversely affect the course of acute myocardial infarction (AMI). Finally, we seek evidence that intensive insulin treatment improves outcome.
