Authors have considered the prevalence of hypertension (HT), myocardial infarction (MI) and stroke (S), in elderly subjects with diabetes, impaired fasting glucose (IFG) and normal fasting glucose (NFG), respectively. A high occurrence of diabetes in elderly subjects has been found. MI and S were more frequent in diabetic group than in IFG and NFG ones. HT proved to be elevated in the total pool, especially in older olds, and with a higher prevalence among those with diabetes. A 5-year follow-up has been carried out. The index of survival for MI and S was lower in subjects with diabetes. The subjects affected by both MI and S displayed the worst index of survival in all the three categories considered, therefore, it can be stated that such an association is a determinant factor of mortality.
