ABSTRACT
Objective To evaluate the correlation between ischemia-modified albumin (IMA) levels and severity of coronary artery lesions in patients with acute coronary syndrome (ACS).Methods This study included 51 in-hospital patients diagnosed as having ACS.All patients had undergone coronary angiography and received the standard treatment for coronary heart disease.Meanwhile,we included 10 healthy volunteers as the control group.Coronary angiography reports were collected,Gensini scores were calculated,and serum IMA levels were measured.Results The IMA levels of patients with ACS were higher than those of the controls (P ＜ 0.05).However,when divided by the degree of coronary artery stenosis,number of vessel lesions,and Gensini scores,the IMA levels showed no significant difference between the groups.The IMA levels were not related with the Gensini scores.The moderate group had a low ratio of TIMI flow grade 3.Conclusion Patients with ACS had higher IMA levels.We found no correlation between IMA level and coronary artery lesions.IMA level may not accurately reflect the severity of coronary artery lesions.Increased IMA level may indicate the unstable status of ischemia.
ABSTRACT
Objective Hyperglycaemia and hyperlipid are common in clinical cardiovascular disease .The article was to ob-serve the change of endothelial and the expression of Rho-kinase in the aorta of rats with hyperglycaemia and hyperlipid and the rela-tionship between them .Methods Healthy male Wistar rats were randomly divided into 3 groups:5 as normal control group , 10 as model group and 10 as drug intervention group .The latter two groups were given high-fat diets for 5 weeks after tail vein injection of streptozocin (STZ) to establish hyperglycaemia and hyperlipid models , then fasudil (inhibitor of Rho-kinases) or saline were respec-tively given intraperitoneally for 4 weeks.Venous blood glucose (VBG), blood lipid levels, ET-1 and eNOS were tested, along with the expression of MYPT-1(the protein substrates of ROCK)、mRNA of RhoA and ROCK. Results Compared with normal control group, the levels of VBG、ET-1、MYPT-1、mRNA of ROCK and Rho A were increased in model group[(6.18±1.14)mmol/L vs (26.36± 3.25)mmol/L,(72.13±6.13 )pg/mL vs (88.22±4.61) pg/mL, (0.54±0.08) v s (1.28±0.17),(0.16±0.20) vs (0.83± 0.12),(0.40±0.18) vs (0.78±0.13),P<0.05].TG、TC、LDL were also higher in model group(P<0.05), while eNOS level was lower in model group than in control group[(24.42±2.13)U/L sv (17.36±1.58)U/L,P<0.05].Compared with model group, the levels of VBG[(17.70±2.69)mmol/L]、TG、TC、LDL, ET-1 [(75.03±2.50)pg/mL]、MYPT-1(0.74±0.01)、mRNA of ROCK(04.0±0.08) and Rho A (0.25±0.07)in drug intervention group were lower(P<0.05), while eNOS level (0.74±0.11) was higher(P<0.05) in drug intervention group than in model group . Conclusion Endothelial dysfunction and over-expression of Rho kinase can be found in hyperglycaemia and hyperlipid rat models .Fa-sudil could improve endothelial function .
