- Patients with diabetes have an unfavourable prognosis after an acute myocardial infarction. The DIGAMI 2 study investigated the effect of various metabolic treatment strategies in type 2 diabetic patients with acute myocardial infarction: acutely introduced, long-term insulin treatment did not improve survival when compared with conventional management at similar levels of glucose control. However, good glucose control seems important since the glucose level was found to be a strong predictor of long-term mortality in this patient category.

- Diabetic patients with acute myocardial infarction have a poor prognosis, which has been attributed to a higher incidence of congestive heart failure and fatal reinfarction. This study reports on the one-year morbidity and mortality in a randomized study with the aim of testing whether insulin-glucose infusion initiated as soon as possible after onset of myocardial infarction and followed by long-term subcutaneous insulin treatment may have a beneficial effect on outcome in diabetic patients. In all, 306 patients were recruited to the insulin-treated group, while 314 patients served as controls. The overall mortality after one year was 19% in the insulin group compared to 26% among controls (P < 0.05). The treatment effect was most pronounced in patients without prior insulin medication and at low cardiovascular risk. In this stratum the in-hospital mortality was reduced by 58% (P < 0.05) and the one-year mortality by 52% (P < 0.02). The most frequent cause of death in all patients was congestive heart failure (66%), but cardiovascular mortality (congestive heart failure, fatal reinfarction, sudden death and stroke) tended to be decreased in insulin-treated patients. However, this difference did not reach the level of statistical significance. The number of reinfarctions was 53 (28% fatal) in the insulin group compared to 55 (45% fatal) in the control group. The two groups did not differ as regards need for hospital care or coronary revascularization during the year of follow-up. In summary, left ventricular failure and fatal reinfarctions contribute to increased mortality in diabetic patients following acute myocardial infarction. Intensive insulin treatment lowered this mortality during one year of follow-up.

- Objectives: We analysed predictors of 1-year mortality following acute myocardial infarction in patients with diabetes mellitus by applying uni- and multivariate statistics on the DIGAMI cohort. Background: Diabetic patients with acute myocardial infarction have a poor prognosis. This may depend on a poor metabolic control, a hypothesis that was tested in DIGAMI, a prospective randomised study. In this trial institution of immediate intensive insulin treatment reduced 1-year mortality by 30%. Methods: We recruited 620 diabetic patients with acute myocardial infarction, 314 of whom served as controls, while the remaining 306 patients were treated with an acute insulin–glucose infusion followed by multidose subcutaneous insulin. Results: Age, previous myocardial damage, duration of the diabetes and previous insulin therapy were significantly related to 1-year mortality, while conventional risk factors lacked independent prognostic weight. Female sex was not linked to mortality when controlling for the confounding effects of other predictors. One of the strongest predictors of a fatal outcome, in particular during the hospital phase, was blood glucose at hospital admission. Beta-blockade appeared to exert a striking, independent secondary-preventive effect. Conclusions: It seems that good metabolic control and not conventional risk factors is of major importance for diabetic patients sustaining acute myocardial infarction. Also treatment with beta-blockade seems to be of special importance in this category of patients.
