Prediabetes and Right Ventricular Function: What Should Be Done for Clarification?

The American Diabetes Association has opened a dysglycemic category termed “prediabetes”. This category includes subjects with fasting blood sugar levels of between 100 and 125 mg/dL or glycated hemoglobin A1c levels of between 5.7% and 6.4% or 2-hour post-glucose loads (75 g) of between 140 and 199 mg/dL.1 This category has been taken into consideration in cardiovascular disease research, including the cardiac imaging field. On the other hand, the right ventricular (RV) function has been a focal point in some investigations.
