Metabolic and cardiac outcomes after acute myocardial infarction

The original DIGAMI protocol recommended using intravenous insulin to manage myocardial infarction from first presentation followed by subcutaneous insulin for 3 months in patients with diabetes. This paper describes the metabolic and cardiac outcomes and barriers to implementing a protocol designed to match the DIGAMI principles across our emergency and cardiology departments. Patients managed using the revised DIGAMI protocol achieved better blood glucose control and had fewer reinfarcts than those managed without insulin. The major barrier to using the protocol appeared to be staff fear of causing hypoglycaemia.<br />
