Molstad P, et al. - This study was performed on patients with a clinical diagnosis of type 1 and type 2 diabetes and on patients without diabetes in a population referred for invasive treatment of coronary disease, to compare long-term and time trends of survival in both groups of patients. Findings demonstrated excess long-term mortality in type 1 and type 2 diabetes. In recent years, reduced mortality has been noted in the nondiabetic and type 2 diabetic patients, but not in type 1 diabetic patients.
