Summary
Brief summary
The effect of hyperinsulinemic euglycaemia (HE) on myocardial ischaemia is unknown. We have previously shown that HE increases myocardial blood flow in healthy individuals. We speculate that following successful revascularisation of a myocardial infarction, HE can improve microvascular flow to both ischaemic and remote non-ischaemic myocardial territories.
