Abstract:
Objective:To explore the correlation among serum uric acid (UA) level and severity of coronary heart disease (CHD) ,adverse cardiovascular events .Methods :Clinical data of 403 patients undergoing coronary angiog-raphy in our hospital were retrospectively analyzed .They were divided into CHD group [n=308 ,including 137 cases with stable angina pectoris (SAP) and 171 cases with acute coronary syndrome (ACS)] and normal control group (n=95 ,non-CHD patients) .UA level was compared among all groups and its correlation with CHD severity was fur-ther analyzed .According to UA level ,CHD patients were divided into low UA group (n=147) and high UA group (n=161) ,after 12-month follow-up ,incidence rate of major adverse cardiovascular events (MACE) uring follow-up was compared between two groups .Results:Serum UA level of ACS group was significantly higher than that of nor-mal control group [ (318.44 ± 69.07)μmol/L vs .(295.38 ± 80.08)μmol/L ,P=0.003];along with number of dis-eased coronary vessels increased and CHD severity aggravated (Gensini score rose ) ,serum UA level showed an in-creasing trend [single-branch (316.58 ± 95.27 ) μmol/L vs . double-branch (335.26 ± 43.26 ) μmol/L vs . multi-branch (346.53 ± 86.74) μmol/L ;low score group (312.42 ± 48.26) μmol/L vs .middle score group (346.58 ± 47.36)μmol/L vs .high score group (363.84 ± 54.68)μmol/L , P<0.05 or <0.01] .Pearson correlation analysis indicated that serum UA level was positively correlated with Gensini score (r=0.583 ,P<0.05);MACE incidence rate in high UA group was significantly higher than that of low UA group (58.38% vs .36.24% , P=0.012) .Con-clusion:Serum uric acid level is positively correlated with severity of coronary heart disease ,which may be an inde-pendent risk factor for coronary heart disease .
