| Study objectives | A tight glucose control with intravenous insulin in patients suffering from acute coronary syndrome (ACS) would decrease their platelet reactivity compared to subcutaneous insulin. On 26/06/2008 the sources of funding field was changed from 'Grant application submitted to the Spanish Foundation for Investigation in Science (FIS). Decision pending as of 11/01/2008' to 'Foundation for Development and Cardiovascular Research (Spain)'. On 10/08/2009 the following changes were made to the trial record: 1. The target number of participants was changed from 200 to 115. 2. The sources of funding was changed from 'Foundation for Development and Cardiovascular Research (Spain)' to 'Foundation for Cardiovascular Research (Fundación Investigación Cardiovascular [FIC]) (Spain)'. |

| Intervention | Patients are randomised to one of two protocols of glycaemic control. Intervention group (therapy A): intensive treatment. The aim was to obtain a glycaemia of 80 to 120 mg/dl (4.44 to 6.66 mmol/l). Infusion of insulin is started and hourly controls of the rate of infusion was carried out according to a chart elaborated by the Diabetes Unit of our centre. After 24 hours of insulin infusion, a nocturnal dose of ultra-slow insulin was calculated, together with fast subcutaneous insulin before meals. Control group (therapy B): standard treatment. The aim was to obtain a glycaemia of less than 180 mg/dl (9.99 mmol/l). The participants were treated with fast subcutaneous insulin before meals, according to a corrective chart, together with slow insulin twice a day (bid). In patients diagnosed with diabetes, the dose of slow insulin was calculated from their previous treatment or according to the weight (0.1 unit per kilogram every 12 h) As of 10/08/2009, recruitment has ended for this trial. The last patient was recruited on 29/07/2009. |
