- Primary Outcome Measures
Name Time Method The principal objective was to determine if the administration of small doses of Acarbose could prevent or delay the appearance of Type 2 DM in a population of subjects with impaired glucose homeostasis. The main criterion for the evaluation of the primary objective was the proportion of diabetic subjects after three years of treatment and another time after three months of wash-out with placebo.
- Secondary Outcome Measures
Name Time Method Evolution of anthropometric measurements Three years and three months. (BMI) The appearance or progression of cardiovascular events: angina, myocardial infarction, cerebrovascular accident, congestive heart failure, peripheral vascular disease, revascularisation procedure Time until the appearance or progression of cardiovascular episodes Delay in the conversion to diabetes mellitus Time until the confirmation of the diagnosis of Diabetes Mellitus Evolution of the cardiovascular risk markers (microalbuminuria, triglycerides, fasting glycaemia, after overload glycaemia, HbA1c, C-peptide, insulinemia) Three years and three months. Regression to the normality (NO impaired glucose homeostasis) Proportion of subjects that had regressed to normality after three years of treatment. Evolution of blood pressure Three years and three months. Evolution of lipid profile Three years and three months.
