2、onventional risk factors in type 2 diabetes does not reduce CVD risk to the same level as in a non-diabetic population Post prandial hyperglycaemia may explain the excess risk seen in diabetes and “prediabetes” Acarbose has been reported* to reduce CVD risk in individuals with “prediabetes”, but its
