Sammanfattning (abstract):
AimsHyperglycaemia during hospitalization for acute myocardial infarction (AMI) is a risk predictor, but attempts to improve the prognosis by insulin-based glucose control have not been consistently successful. Increased glycaemic variability, a potential effect of insulin treatment, has been linked to a worse prognosis in critically ill patients. The present aim was to study the possibility of such a relation in patients with type 2 diabetes (T2DM) and AMI.Method and resultsWe studied 578 T2DM patients who had glucose levels measured hourly while receiving an insulin-glucose infusion during the first 48 h of hospitalization for AMI. Three measures of glycaemic variability: root mean square error (RMSE), range, and slope were studied in relation to a composite endpoint of mortality, stroke, and reinfarction and to mortality.In unadjusted analyses, the mean level of glycaemic variability did not differ between patients who died during 12 months of follow-up compared with those who survived. In a Cox regression model adjusting for age and previous congestive heart failure, there was no increased risk for the composite endpoint associated with increased glycaemic variability; RMSE: hazard ratio (HR) 1.09 [95% confidence interval (CI) 0.93-1.27; P = 0.28], range: HR 1.01 (95% CI: 0.98-1.05; P = 0.47), and slope: HR 1.01 (95% CI: 0.99-1.04; P = 0.40). There was furthermore no increased risk in mortality; RMSE HR 1.14 (95% CI: 0.93-1.38; P = 0.21), range HR 1.03 (95% CI: 0.98-1.08; P = 0.28), and slope HR 1.01 (95% CI: 0.98-1.04; P = 0.55).ConclusionThe 1-year risk for death, reinfarction, or stroke did not relate to glycaemic variability in T2DM patients with AMI treated with insulin infusion.
