An A1c of 5.7% Indicates Greater Heart Risk

Researchers found participants with normal glucose tolerance but A1C rates between 5.7% and 6.4% had increased intima-media thickness and augmentation and augmentation index, suggesting that an A1C threshold of 5.7% may help better identify patients at greater cardiovascular risk. "These results suggest that an HbA1c cutoff of 5.7% is more sensitive for the identification of subjects at high cardiovascular risk." Di Pino A. Diabetes Care. 2014;doi:10.2337/dc13-2357.
