Tongue image characteristics of phlegm-blood stasis syndrome in stable angina pectoris of coronary heart disease and influencing factors
To observe the tongue image characteristics of phlegm-blood stasis syndrome in patients with stable angina pectoris of coronary heart disease, and to investigate factors influencing these tongue features.
Methods
2
From May 2022 to January 2023, a total of 90 patients with stable angina pectoris of coronary heart disease were enrolled at Xiyuan Hospital, China Academy of Chinese Medical Sciences, including 47 patients with phlegm-blood stasis syndrome (phlegm-blood stasis group) and 43 patients without phlegm-blood stasis syndrome (non-phlegm-blood stasis group). Tongue images were collected using a tongue diagnostic instrument and analyzed, and potential influencing factors were assessed.
Results
2
Significant differences were observed between the two groups in tongue coating and sublingual collaterals (
P
<
0.05). The phlegm-blood stasis group predominantly had greasy co
atings, while the non-phlegm-blood stasis group predominantly had thin coatings. Sublingual collaterals in the phlegm-blood stasis group were mainly moderately to severely tortuous, whereas the non-phlegm-blood stasis group showed mostly mild to moderate tortuosity. No significant differences were found in the tongue tip RGB values between the two groups (
P
>
0.05), but the tongue body stasis index was significantly higher in the phlegm-blood stasis group (
P
<
0.05). Age, alcohol consumption, triglycerides (TG), and LDL-C had no effect on thin coating in phlegm-blood stasis patients (
P
>
0.05); age was an independent factor influencing greasy coating (
P
<
0.05); smoking history was an independent factor affecting the tongue body stasis index (
P
<
0.05).
Conclusion
2
Patients with stable angina pectoris of coronary heart disease and phlegm-blood stasis syndrome exhibit thicker and greasy tongue coatings, sublingual collaterals that are moderately to severely tortuous, and higher tongue body stasis index. Age influences the presence of greasy coating, and smoking history affects the tongue body stasis index.
