OBJECTIVETo study the correlation between the Chinese medicine (CM) syndrome types of the Uighur and Han people and levels of blood lipids and fibrinogen in premature coronary heart disease (PCHD) patients.
METHODSRecruited were 196 Uighur and 189 Han patients with PCHD first confirmed by coronary angiography at the Heart Center of First Affiliated Hospital of Xinjiang Medical University and Traditional Chinese Medicine Hospital Affiliated to Xinjiang Medical University. Another 60 healthy volunteers were recruited as the healthy control group. CM syndromes were typed by physicians or those having higher professional titles at the cardiac internal medicine. The contents of triglyceride (TG) and total cholesterol (TC) were detected using oxidase method. The high-density lipoprotein cholesterol (HDL-C) level was detected using chemical modification enzymic method. The low-density lipoprotein cholesterol (LDL-C) level was detected using selective dissolution. The fibrinogen (FIB) level was detected using Clauss congeal principle.
RESULTSThe CM syndrome types of Uighurs were sequenced as filthy turbidity and phlegm obstruction syndrome (82 cases, 21.3%) > qi deficiency and blood stasis syndrome (61 cases, 15.84%) >cold accumulation in Xin meridian syndrome (39 cases, 10.13%) >Xin-Shen yin deficiency syndrome (14 cases, 3. 63%). The CM syndrome types of the Han nationality were sequenced as qi deficiency and blood stasis syndrome (69 cases, 17.92%) >filthy turbidity and phlegm obstruction syndrome (67 cases, 17.40%) > cold accumulation in Xin meridian syndrome (42 cases, 10.91%) > Xin-Shen yin deficiency syndrome (11 cases, 2.86%). There was no statistical difference in the syndrome type distribution between the two groups (P >0.05). Compared with the healthy control group, the levels of TG, LDL-C, and FIB increased, and the HDL-C level decreased in patients of filthy turbidity and phlegm obstruction syndrome and qi deficiency and blood stasis syndrome of the patient group. The HDL-C level decreased in the Uighur patients of Xin-Shen yin deficiency syndrome, showing statistical difference (P < 0.01, P < 0.05). Compared with the Han people of the same syndrome type, the TG level increased and the HDL-C level decreased in the Uighur patients of filthy turbidity and phlegm obstruction syndrome. The FIB level increased in the Uighur patients of qi deficiency and blood stasis syndrome with statistical difference (P<0.05). In the Uighur patients, filthy turbidity and phlegm obstruction syndrome was positively correlated with TG (r=0.469) and FIB (r=0.464), and negatively correlated with HDL-C (r=-0.382). Qi deficiency and blood stasis syndrome was positively correlated with FIB (r=0.72) with statistical difference (P<0.01, P<0.05). In the Han patients, filthy turbidity and phlegm obstruction syndrome was positively correlated with TG (r=0.445) and FIB (r=0.372), and negatively correlated with HDL-C (r=-0.37). Qi deficiency and blood stasis syndrome was positively correlated with TG (r=0.471) and FIB (r=0.459) with statistical difference (P<0.01, P<0.05).
CONCLUSIONCM syndrome types were correlated with TG, HDL-C, and FIB in PCHD Han and Uighur patients.
