Impact of Tight Glycaemic Control in Acute Myocardial Infarction
To determine whether tight glycaemic control with insulin improves myocardial function and myocardial perfusion (measured by myocardial contrast echocardiography) and novel vascular risk factors in patients with acute myocardial infarction and hyperglycaemia.
Drug: Insulin (tight blood glucose control)
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Impact of Tight Glycaemic Control With Insulin on Novel Vascular Disease Risk Factors and Myocardial Function and Perfusion in Acute Myocardial Infarction Patients With Hyperglycaemia|
- Difference in the change in wall motion score index between admission, day 3-5 and after 3 months in the two treatment arms.
- Changes in inflammatory/endothelial markers and myocardial perfusion from admission, day 3-5 and after 3 months between the two treatment arms

We will randomise patients with acute myocardial infarction and blood glucose levels (BGLs) >=10mmol/L within 24 hours of pain onset, to either tight glucose control (aiming BGLs 4.5 - 7mmol/L) with an insulin infusion (for 24 hours) followed by subcutaneous insulin or standard control (BGL 6 - 12mmol/L) without the use of an insulin infusion. Serial myocardial contrast echocardiography will measure changes in myocardial perfusion and function from baseline to 3 months between each group. We will also measure changes in inflammatory and endothelial markers over this time to see whether tight glucose control improves these surrogate endpoints.
