- BACKGROUND: The objective of the current study was to examine the efficacy and tolerability of the beta-blocker metoprolol succinate controlled release/extended release (CR/XL) in patients with diabetes in the Metoprolol CR/XL Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF). METHODS: The Cox proportional hazards model was used to calculate hazard ratios (HR) for convenience expressed as relative risks (risk reduction = 1-HR), and 95% confidence intervals (CI). RESULTS: The risk of hospitalization for heart failure was 76% higher in diabetics compared to non-diabetics (95% CI 38% to 123%). Metoprolol CR/XL was well tolerated and reduced the risk of hospitalization for heart failure by 37% in the diabetic group (95% CI 53% to 15%), and by 35% in the non-diabetic group (95% CI 48% to 19%). Pooling of mortality data from the Cardiac Insufficiency Bisoprolol Study II (CIBIS II), MERIT-HF, and the Carvedilol Prospective Randomized Cumulative Survival Study (COPERNICUS) showed similar survival benefits in patients with diabetes (25%; 95% CI 40% to 4%) and without diabetes (36%; 95% CI 44% to 27%); test of diabetes by treatment interaction was non-significant. Adverse events were reported more often on placebo than on metoprolol CR/XL. CONCLUSIONS: Patients with heart failure and diabetes have a much higher risk of hospitalization than patients without diabetes. Regardless of diabetic status, a highly significant reduction in hospitalizations for heart failure was observed with metoprolol CR/XL therapy, which was very well tolerated also by patients with diabetes. Furthermore, the pooled data showed a statistically significant survival benefit in patients with diabetes.

- AIM: To describe the association between a history of diabetes and outcome among patients suffering an in-hospital cardiac arrest. METHOD: All patients suffering an in-hospital cardiac arrest in whom cardiopulmonary resuscitation (CPR) was attempted at Sahlgrenska University Hospital in Göteborg between 1994 and 2006 and at nine further hospitals in Sweden between 2005 and 2006. RESULTS: In all, 1810 patients were included in the survey, 395 (22%) of whom had a previous history of diabetes. Patients with a history of diabetes differed from those without such a history by having a higher prevalence of previous myocardial infarction, stroke, heart failure and renal disease. They were more frequently treated with anti-arrhythmic drugs during resuscitation. Whereas immediate survival did not differ between groups (51.7% and 53.1%, respectively), patients with diabetes were discharged alive from hospital (29.3%) less frequently compared with those without diabetes (37.6%). When correcting for dissimilarities at baseline, the adjusted odds ratio for being discharged alive (diabetes/no diabetes) was 0.57 (95% CL 0.40-0.79). CONCLUSION: Among patients suffering an in-hospital cardiac arrest in Sweden in whom CPR was attempted, 22% had a history of diabetes. These patients had a lower survival rate, which cannot simply be explained by different co-morbidity.
