Hi,
Your fasting glucose may be 95, which is still at the high end of normal, but your
hba1c of 6.4, gives you an average blood sugar of about 150, which is well above normal. If you wait until your hba1c is 7.0, this will give you an average blood sugar of close to 180, nearly double normal. There is much consensus that the risk of heart disease rises significantly as hba1c increases above 5.0.
