To explore the differences in facial diagnosis characteristics between patients with hypertension combined with coronary heart disease(CHD)，patients with pure hypertension，and healthy individuals.Methods:The facial images of the hypertension group，hypertension combined with CHD group，and healthy group were collected and analyzed using the Daosheng DS01-B facial diagnostic instrument.Results:Compared to healthy individuals，both the hypertension group and the hypertension combined with CHD group exhibited reduced R，G，B，H，V，and L values，while S and a values increased(P<0.01).Compared to the hypertension group，the hypertension combined with CHD group showed a further reduction in H value(P<0.01) and a decrease in R，G，B，H，V，and L values(P<0.05，P<0.01)，while S and b values increased(P<0.01).Conclusion:Both the hypertension group and the hypertension combined with CHD group had darker red facial complexions compared to healthy individuals，with the hypertension combined with CHD patients exhibiting a more dull complexion than those with pure hypertension.These findings provide objective clinical evidence for the diagnosis and treatment of hypertension and CHD.
