Abstract:
Objective To detect the mechanism of serum uric acid (UA) in different types of coronary heart disease (CHD).Methods 88 patients were divided into three groups：the control group，stable angina (SA) group and acute coronary syndrom (ACS) group.The levels of UA，alpha-granule membrane protein 140 (GMP-140)，von Willebrand factor(vWF)，plasminogen activator inhabitor typed (PAI-1)，Thromboxane B_2 (TXB_2) and C-reacting protein(CRP) were measured.Results ①UA and CRP in ACS group were higher than that in SA group and control group [(392.1±68.57) μmol/L and (42.2±39.4) mg/L vs (370.50±58.80) μmol/L and (18.9±17.1) mg/L vs (286.00±65.31) μmol/L and (2.5±0.7) mg/L，P＜0.05)].For UA，there was no difference between ACS and SA group(P＞0.05)；CRP was higher in ACS group than in SA group (P＜0.05).②vWF and TXB_2 were higher in ACS[(1.65±0.48)%，(19.73±18.66)ng/L]and SA group[(1.35±0.49)%，(11.18±10.71) ng/L]than in control group[(1.07±0.26)%，(6.46±5.41) ng/L，P＜0.05]，and those were higher in ACS group than in SA group (P＜0.05).③GMP-140 and PAI-1 were higher in ACS [(13.04±0.99) μg/L and (65.65±14.76) μg/L]and SA group[(12.55±0.74) μg/L and (62.69±12.24) μg/L]than in control group [(12.32±0.29) μg/L，(50.78±13.88) μg/L，P＜0.05].There were no differences between ACS and SA group (P＞0.05).④Comparing hyperuricemia group and non-hyperuricemia group in CHD patients：the CRP(71.3±18.9) mg/L，vWF(1.08±0.52) %，GMP-140(13.57±1.11) μg/L，TXB_2 (57.26±47.84)ng/L，PAI-1 (72.12±9.23) μg/L in ACS group possessing hyperuricemia were higher than non-hyperuricemia group [CRP (20.7±17.9) mg/L，vWF (0.84±0.54) %，GMP-140 (13.23±1.07) μg/L，TXB_2 (26.70 + 23.83) ng/L，PAI-1 (61.30±12.07) μg/L](t=7.394，0.008，0.227，7.605，0.421，P＜0.05)；CRP(31.1±18.9)mg/L and TXB2 (21.54±3.90) ng/L in SA group possessing hyperuricemia group were higher than non-hyperuricemia group[(10.9±10.1)mg/L and (5.02±4.93) ng/L，t=0.494，8.669，P＜0.05].Logistic stepwise regression analysis indicated that the related factors with ACS were UA(OR=1.046)，CRP(OR=7.615)，PAI-1(OR=1.301)，PT(OR=0.300)and TG(OR=2.243) (P＜0.05).Conclusions UA is an important risk factor in CHD patients.UA can induce different types of CHD by damaging blood vessel endothelium function，activating platelet，changing coagulation and causing inflammatory.
