血尿酸水平与冠心病严重程度的相关性分析

目的 探讨血尿酸水平与冠心病及其病变严重程度的相关性.方法 选取112例行冠状动脉造影的患者,分为3组,急性冠状动脉综合征(ACS)患者58例(ACS组),稳定型心绞痛患者25例(稳定型心绞痛组),非冠心病患者29例(对照组),进行血尿酸测定,冠状动脉病变程度用冠状动脉病变支数及Gensini积分表示,按病变范围分为对照组(29例)、单支病变组(24例)、双支病变组(26例)、三支病变组(33例)；按Gensini积分分为0～1分组(29例)、2～20分组(28例)、21～40分组(30例)、＞40分组(25例).结果 ACS组血尿酸水平显著高于对照组和稳定型心绞痛组[( 369.61±91.97)μmol/L比(298.33±92.46)、(330.43±87.42)μmol/L](P＜ 0.05).对照组血尿酸水平显著低于单支、双支和三支病变组[ (298.33±92.46)μmol/L比(331.77±86.33)、(368.24±95.21)、(396.82±94.45)μmol/L](P＜0.05),单支病变组血尿酸水平显著低于双支病变组和三支病变组(P＜0.05).0～1分组[(298.33±92.46)μmol/L]和2～20分组[(320.77±86.33)μmol/L]血尿酸水平显著低于21～40分组[(366.61 ±91.97) μmol/L]和＞40分组[(402.82±91.97)μ mol/L](P＜0.05).21 ～40分组血尿酸水平低于＞40分组(P＜0.05).血尿酸水平与Gensini积分的对数呈正相关(r=0.348,P＜ 0.05).结论 血尿酸与冠状动脉稳定性、狭窄程度以及范围显著相关,有助于临床评价冠心病病变程度及其进展.

Correlation between serum uric acid level and severity of coromry artery

Objective To investigate the correlation between serum uric acid level and severity of coronary artery disease.Methods The concentrations of serum uric acid in 112 patients whom had received coronary arteriongraphy(CAG) was measured,among of them,acute coronary artery syndrome (ACS) with 58 cases( ACS group ),stable angina cordis with 25 cases( stable angina cordis group),non-coronary disease with 29 cases(control group).The severity of coronary artery lesion was evaluated by the number of stenosis vessel and Gensini score.They were divided into control group (29 cases),single vessel lesion group (24 cases),double vessel lesion group(26 cases),triple vessel lesion group(33 cases ) according to the number of stenosis vessel and 0-1 score group(29 cases),2-20 scores group(28 cases),21-40 scores group(30 cases),＞40 scores group (25 cases) according to the Gensini score.Results The concentrations of serum uric acid in ACS group were higher than those in control group and stable angina cordis group[ (369.61 ± 91.97 ) μ mol/Lvs. (298.33 ±92.46),(330.43 ±87.42)μmol/L] (P ＜0.05).The concentrations of serum uric acid in control group were lower than those in single vessel lesion group,double vessel lesion group and triple vessel lesion group [(298.33 ±92.46)μmol/L vs. (331.77 ±86.33),(368.24 ±95.21),(396.82 ±94.45) μ mol/L] (P ＜ 0.05).The concentrations of serum uric acid in single vessel lesion group were significantly lower than those in double vessel lesion group and triple vessel lesion group (P ＜ 0.05 ).The concentrations of serum uric acid in 0-1 score group [ (298.33 ± 92.46) μ mol/L] and 2-20 scores group [ (320.77 ± 86.33 ) μ mol/L ] were respectively lower than those in 21-40 scores group [ (366.61 ± 91.97 ) μ mol/L ] and ＞ 40 scores group [ (402.82 ± 91.97 ) μ mol/L] (P ＜ 0.05 ).The concentrations of serum uric acid in ＞ 40 scores group was higher than that in 21-40 scores group (P ＜ 0.05 ).Serum uric acid concentrations was positively correlated with the log of Gensini score (r =0.348,P ＜ 0.05 ).Conclusion The increase in serum uric acid might reflect increase in severity of coronary artery stenosis.
