Blood homocysteine value is an important indicator of the risk of peripheral vascular disease and cardiovascular disease, the higher the value, the higher the risk, and 15umol/L is used as the diagnostic criterion for the disease in clinical practice. However, current guidelines suggest that the optimal value of blood homocysteine is 6.3umol/L or less, and the clinical intervention value is 10umol/L. That is to say, when the value of blood homocysteine is 10umol/L, it is already necessary to take measures to intervene in order to prevent it from further elevation and the emergence of vascular diseases.
