Type 2 Diabetes mellitus (DM2) is a complex, multifactorial and worldwide metabolic disease that affects quality and lifestyle of patients. Patients with diabetes can have a 15-year or more reduction of lifetime and the high mortality is due to cardiovascular (CV) complications. Effective strategies for the reduction of the impact of DM2 on CV disorders for the next years and attention concerning to strategies of prevention, mainly for the populations with larger risk of developing the disease, are essential. In that context, impaired glucose tolerance (IGT) and impaired fasting glycemia (IFG) must suffer intervention strategies in order to minimize the risk for diabetes. Behavior modification (diet therapy and physical activity) must be stimulated, and pharmacological agents have to be used when indicated. Studies worldwide have been confirming the effectiveness of lifestyle strategies and even the use of pharmacological agents for the prevention of DM2.
