CONCLUSIONS

37

• The epidemic of diabetes is very alarming most especially in Western

Pacific and Southeast Asia where majority of patients are located and exponential increase in new cases is expected.

• Diabetes is often associated with other cardio-metabolic risk factors

that further increase the risk of developing serious and costly complications.

• Cardiovascular death is the most frequent cause of death among

diabetic patients.

• A significant treatment gap exists among diabetic patients in Asia with

suboptimal attainment of A1c, blood pressure, and hypertension goals that may lead to cardiovascular diseases.

• Optimization of disease management strategies and programs must be

prioritized to help curb the diabetes epidemic.
