Abstract:
Objective To investigate relationship among Brachial-ankle pulse Wave Velocity (baPWV),Homocysteine (Hcy),Serum Matrix Metallopro Teinases-9 (MMP-9) and coronary heart disease.Methods Sixty-six cases of patients diagnosed as coronary heart disease according to the coronary angiography showed any one of the main coronary arteries (left main,left anterior descending,left circumflex artery,right coronary artery) diameter stenosis≥ 50％ were selected into coronary heart disease from June 2009to March 2011 hospitalized in the Second Affiliated Hospital of Ningxia Medical Cardiology.And 40 cases of healthy people who had medical examination over the same period were selected into the normal control group.The 66 cases of patients were further divided into single-branch-affected group (n =18),two-branchaffected group(n =25) and multi-branch-affected group (n =23) according to the branches of coronary artery pathological changes shown in coronary angiography.Detected and compared baPWV,Hcy and MMP-9 among these groups.Results The baPWV,Hcy and MMP-9 in coronary heart disease group were significantly higher than those in the control group (baPWV:(2132 ±240) cm/s vs (1360 ±81) cm/s,t =23.97,P ＜0.01 ;Hcy:(14.32 ± 5.20) μmol/L vs (6.50 ± 1.40) μmol/L,t =11.54,P ＜ 0.01 ; MMP-9:(768.0 ± 95.3) μg/L vs (228.0 ±56.2) μg/L,t =36.69,P ＜0.01) ;The baPWV,Hcy and MMP-9 in multi-branch-affected group were significantly higher than those in single-branch-affected and two-branch-affected group; The baPWV,Hcy and MMP-9 in two-branch-affected group were higher than those in single-branch-affected group (baPWV (2041 ±168) cm/s vs (1873 ± 150) cm/s vs (1560 ± 172) cm/s,F =45.36,P ＜0.01 ;Hcy:(21.31 ±6.30) μmol/L vs (15.32 ± 5.80) μmol/L vs (10.50 ± 3.20) μmol/L,F =36.18,P ＜ 0.01 ;MMP-9:(1042.0 ± 180.2) μg/L vs (940.0 ± 175.8) μg/L vs (723.0 ± 102.2) μg/L,F =41.06,P ＜ 0.01).The serum MMP-9 was significantly positive correlated with baPWV and Hcy (r =0.630,P ＜0.01 ;r =0.351,P ＜0.05) ;The Hcy was significantly positive correlated with baPWV (r =0.475,P ＜ 0.05) in the coronary heart disease group.Conclusion The baPWV,Hey and MMP-9 were related with the degree of artery stenosis in coronary heart disease.Combined detection of these three markers can be used to assess the risk of coronary heart disease.
