Glucose in the coronary care unit: some evidence, more questions

Around a quarter of patients presenting to the hospital with chest pain have diabetes. Given the close relationship between these disorders, it is perhaps surprising that the optimal way to manage glycaemia in the coronary care unit remains uncertain. In the current issue of Cardiovascular Endocrinology, Hailpern and colleagues highlight increased mortality among patients with chest pain and diabetes who have HbA1c levels less than 6.5% (48 mmol/mol) on admission to a large municipal hospital in Bronx, New York.
