Hyperglycaemia in acute coronary syndromes: summary of NICE guidance.

Hyperglycaemia is common in patients who are admitted to hospital with acute coronary syndrome. In the EuroHeart Survey on diabetes, 22% of people admitted to hospital as emergency cases because of coronary artery disease were found to have undiagnosed diabetes after a glucose tolerance test, with a further 36% found to have impaired glucose tolerance.Hyperglycaemia is a powerful predictor of poorer survival and increased risk of complications while in hospital. Despite this, hyperglycaemia remains under-recognised as a risk factor for acute coronary syndrome and is often untreated. This article summarises the recommendations from the National Institute for Health and Clinical Excellence (NICE) on the management of hyperglycaemia within the first 48 hours of a patient’s admission to hospital for acute coronary syndrome.
