C-reactive Protein Level,Apolipoprotein B-to-apolipoprotein A-1 Ratio,and Risks of Ischemic Stroke and Coronary Heart Disease among Inner Mongolians in China

Objective We aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1（ApoB/ApoA-1） ratio on the incidence of ischemic stroke（IS） or coronary heart disease（CHD） in a Mongolian population in China.Methods From June 2003 to July 2012,2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation.All the participants were divided into four subgroups according to C-reactive protein（CRP） level and ApoB/ApoA-1 ratio.Cox proportional hazard models were used to estimate the hazard ratios（HRs） and 95% confidence intervals（CIs） for the IS and CHD events in all the subgroups.Results The HRs（95% CI） for IS and CHD were 1.33（0.84-2.12）,1.14（0.69-1.88）,and 1.91（1.17-3.11） in the ‘low CRP level with high ApoB/ApoA-1＇,‘high CRP level with low ApoB/ApoA-1＇,and ‘high CRP level with high ApoB/ApoA-1＇ subgroups,respectively,in comparison with the ‘low CRP level with low ApoB/ApoA-1＇ subgroup.The risks of IS and CHD events was highest in the ‘high CRP level with high ApoB/ApoA-1＇ subgroup,with statistical significance.Conclusion High CRP level with high ApoB/ApoA-1 ratio was associated with the highest risks of IS and CHD in the Mongolian population.This study suggests that the combination of high CRP and ApoB/ApoA-1 ratio may improve the assessment of future risk of developing IS and CHD in the general population.

Relationship between high sensitivity C-reactive protein and angiographic severity of coronary artery disease

Background Coronary artery disease(CAD)remains a leading cause of morbidity and mortality.Cytokines play a potential role in atherosclerosis pathogenesis and progression.We investigated the association between high sensitive C-reactive protein(hs CRP)and severity of CAD.Methods CAD patients were stratified according to hs CRP cut-off value into high levels hs CRP group(≥8.4 mg/L)and low levels hs CRP group(<8.4 mg/L).Severity of CAD was assessed according to artery stenosis degree and the number of vessel involved.Statistical analysis was performed using Statistical Package for the Social Sciences(SPSS,version 23.0).Results The mean age was 60.3±11.0 years.The level of hs CRP was increased and ranged from 0.2 to 1020.0 mg/L.Biochemical risk factors and severity of CAD didn’t show significant differences between the two groups.In multivariate linear analysis,cardiac troponin I(c Tn I)and serum amyloid A(SAA)were predictors of hs CRP.As shown in receiver operating characteristic(ROC)curve analysis performed in patients with ST-segment elevation myocardial infarction(STEMI)and compared to myonecrosis biomarkers,hs CRP(area under the curve(AUC):0.905;95%CI:0.844-0.966;P<0.001)could be a powerful predictor marker in evaluating the infarct size after myocardial infarction but not better than c Tn I.Conclusions Hs CRP levels were not associated with the severity of CAD but could be useful in the evaluation of myocardial necrosis in patients with STEMI.

Myeloperoxidase and High-Sensitivity C-Reactive Protein for Predicting Major Adverse Cardiovascular Events in Patients with Coronary Heart Disease

Background: Research has shown that high-sensitivity C-reactive protein (hs-CRP) is a major inflammatory marker for prediction of acute coronary syndrome (ACS). Myeloperoxidase (MPO) also plays an important role in atherosclerosis initiation and development. In present study, the major adverse cardiovascular events (MACEs) of patients with coronary heart disease (CHD) were investigated. Methods: MPO, hs-CRP and ACS-related risk factors from 201 ACS (78 AMI and 123 UAP) and 210 non-ACS (84 SAP and 126 non-CHD) patients confirmed by coronary angiography were detected, and the data were analyzed with receiver operating characteristic (ROC) curve and Spearman’s correlation coefficients. MACEs of 285 CHD patients were investigated during the 4-year period follow-up from March 2010 to May 2014. Results: The areas under ROC curve for diagnosing ACS were 0.888 (95% CI 0.843 - 0.933) for MPO, and 0.862 (95% CI 0.815-0.910) for hs-CRP, respectively. There were significantly correlations between MPO and hs-CRP in both ACS and non-ACS groups. Regarding to ACS patients, both MPO and hs-CRP were positively correlated with BMI, TC, TG, LDL-C and Hcy. Prospective study demonstrated that the incidences of MACEs associated significantly with elevated MPO baseline level (yes vs no, OR 7.383, 95% CI 4.095 - 13.309) and high hs-CRP baseline level (yes vs no, OR 4.186, 95% CI 2.469 - 7.097) in CHD patients. Conclusions: The present study provides the epidemiological evidence that elevated baseline MPO and hs-CRP levels are both valuable predictors of MACEs in CHD patients. MPO and hs-CRP would prompt the progression of atherosclerosis and development from SAP to ACS.

Dietary Magnesium Intake Related to C-Reactive Protein in Newly Diagnosed Coronary Heart Disease Patients at Middle Zone, Gaza Strip. A Hospital Based Study

Coronary Heart Disease (CHD) is a highly prevalent disease all over the world. Magnesium (Mg) plays a role in CHD but it is still unclear. C-Reactive Protein (CRP) is an inflammatory marker which may rise in CHD. Aim of study: To assess the impact of dietary Mg intake and its level in relation to CRP among newly diagnosed CHD at middle zone of Gaza Strip. Methodology: Patients (n = 140) with confirmed CHD, 50 ± 10 years, presented in the cardiac care unit at Aqsa Martyr’s Hospital between 1 April 2012 and 30 December 2012, were enrolled in this cross-sectional study after taking consent. ECG, clinical status, and cardiac markers were used to confirm diagnosis by cardiologist. Food frequency questionnaire was used to assess Mg intake and calcium intake in addition to measurement of its level in serum. CRP latex slide was used for measurement of CRP. Results: Mg intake and serum Mg were?inversely associated with risk?of CHD. Mean of serum Mg among cases (1.80) was lower than controls (2.41) (P = 0.001). Percent of positive CRP was higher in cases (32.9%) than controls (12.9%) (P = 0.005). Mean of serum Mg was (1.96 ± 0.47) for positive CRP which was lower than the mean of serum Mg (2.15 ± 0.44) for negative CRP. Conclusion: Newly diagnosed patients with CHD have a positive CRP, low serum and low?Mg intake, and low serum Mg was associated with elevated CRP.

Clinical perspective on C-reactive protein in prognostication of major adverse cardiac events in the elderly with established coronary heart disease

The systemic response to tissue injury, regardless of cause is characterized by a cytokine-mediated alteration in the hepatic synthesis of a number of different plasma proteins,known collectively as 'acute phase reactants'. These proteins include C-reactive protein, serum amyloid A protein, alphal glycoprotein, ceruloplasmin, alpha macroglobulins, complement components (C1-C4, factor B, C9, C11), alpha1antitrypsin, alpha1 antichymotrypsin, fibrinogen, prothrombin,factor Ⅷ, plasminogen, haptoglobin, ferritin, immunoglobulins and lipoproteins. The initiation of the acute phase response is linked to the production of hormone-like polypeptide mediators now called cytokines, namedly, interleukin 1(IL-1),tumor necrosis factor, interferon gamma, interleukin 6 (IL-6),leukemia inhibitory factor, ciliary neurotropic factor, oncostatin M, and interleukin 11 (IL- 11).……

Vitamin D Status, C-Reactive Protein and Risk of Coronary Artery Disease—A Hospital-Based Study

Coronary artery disease (CAD) is a leading cause of deaths of women and men worldwide. In this study we tried to assess the relationship between Vitamin D status and CAD. Vitamin D has a big role in the body and debate on its effect on the heart and coronary arteries still exits. C-reactive protein (CRP) is an inflammatory marker which may rise in CHD. Aim: To determine the relationship between Vitamin D status and CRP and CAD risk among patients at middle zone of the Gaza Strip. Methodology: A retrospective case-control, hospital-based study was conducted at Al-Aqsa Martyr’s Hospital in Dier El-Balah City from August 2014 to October 2014. Patients (n = 100) aged above 40 years with confirmed CAD history were recruited using a purposeful, non-random sampling. Vitamin D status assessed by food frequency questionnaire of dietary Vitamin D and serum Vitamin D. Serum Vitamin D was measured using Calbiotech’s 25-OH Vitamin D ELISA and serum CRP was measured by the latex agglutination. SPSS V.19 used for data analysis. Results: Mean of age among cases was (68.28 ± 8.01) higher than controls (57.82 ± 9.61) (P = 0.01);percent of males (54%) was higher than females (46.0%) among cases. Sun exposure and mean duration of daily exposure to sunlight were higher in cases (P > 0.05). Cases were consumed less servings of Vitamin D rich food than controls (P > 0.05). Percent of Vitamin D deficiency among cases (42%) was higher than controls (16.0%) (P = 0.002). Mean of serum Vitamin D in association with positive CRP was (79.95 ± 70.6) lower than those with negative CRP (106.06 ± 68.966) (P = 0.13). Percent of positive serum CRP among cases 30% was higher than controls 10% (P = 0.01). Conclusion: Vitamin D deficiency was associated with positive CRP in patients with CAD. Vitamin D may have an anti-inflammatory effect regarding to our results.

Stromelysin-1 Gene Promoter 5A/6A Polymorphism and Plasma C-Reactive Protein in Patients with Coronary Artery Disease and Myocardial Infarction

Objective: To study the associations of stromelysin-1 (MMP3) gene 5A/6A polymorphism with plasma high-sensitivity C-reactive protein (hs-CRP) level in coronary artery disease (CAD) and myocardial infarction (MI). Methods: The MMP3 5A/6A genotypes and plasma hs-CRP levels were determined in 405 non-CAD subjects and 395 angiography-documented CAD patients, 157 with MI and 238 with non-MI. Results: The percentage of the 5A/5A genotype was significantly (p < 0.001) greater in CAD than non-CAD subjects and in MI than non-MI patients. Plasma hs-CRP level of the 5A/5A genotype was significantly (p < 0.05) higher than that of the 6A/6A genotype in CAD and MI but not in non-MI patients. On logistic regression analysis, the odds ratio of the 5A/5A genotype for CAD was 2.11 (95% CI, 1.15 - 3.88, p < 0.05) and for MI was 3.05 (95% CI, 1.54 - 6.04, p < 0.005). Conclusions: This study showed a correlation of the 5A/5A genotype of MMP3 promoter with higher plasma hs-CRP level in CAD patients with MI.

Lipoprotein(a)variability is associated with mean follow-up Creactive protein in patients with coronary artery disease following percutaneous coronary intervention

BACKGROUND Increased lipoprotein(a)[lp(a)]has proinflammatory effects,which increase the risk of coronary artery disease.However,the association between lp(a)variability and follow-up C-reactive protein(CRP)level in patients undergoing percutaneous coronary intervention(PCI)has not been investigated.AIM To explore the association between lp(a)variability and mean CRP levels within the 1st year post-PCI.METHODS Results of lp(a)and CRP measurements from at least three follow-up visits of patients who had received PCI were retrospectively analyzed.Standard deviation(SD),coefficient of variation(CV),and variability independent of the mean(VIM)are presented for the variability for lp(a)and linear regression analysis was conducted to correlate lp(a)variability and mean follow-up CRP level.The relationship of lp(a)variability and inflammation status was analyzed by restricted cubic spline analysis.Finally,exploratory analysis was performed to test the consistency of results in different populations.RESULTS A total of 2712 patients were enrolled.Patients with higher variability of lp(a)had a higher level of mean follow-up CRP(P<0.001).lp(a)variability was positively correlated with the mean follow-up CRP(SD:β=0.023,P<0.001;CV:β=0.929,P<0.001;VIM:β=1.648,P<0.001)by multivariable linear regression analysis.Exploratory analysis showed that the positive association remained consistent in most subpopulations.CONCLUSION Lp(a)variability correlated with mean follow-up CRP level and high variability could be considered an independent risk factor for increased post-PCI CRP level.

The prognostic role of high-sensitivity C-reactive protein in patients with acute myocardial infarction

1 Introduction Inflammation is one of the main mechanisms in the pathogenesis of atherosclerosis,and the interest to the evaluation of inflammatory biomarkers in coronary artery disease(CAD)has been increasing over the last decade.[1,2]Destabilization of chronic artery plaques,which leads to acute coronary syndromes,has been associated with inflammatory status.[1,3]。

The changes of Hs-CRP and WBC count after percutaneous coronary intervention in different types of coronary heart diseases

Objective： To investigate the regulation of High sensitive C-reactive protein（Hs-CRP） and WBC count in patients with coronary heart disease（CHD） by percutaneous transluminal intervention（PCI） and to discuss the mechanism of inflammatory reaction after coronary stenting. Methods：127 patients who received successful percutaneous transluminal coronary stenting, were divided into groups of stable angina（SAP）, unstable angina（UAP）, and acute myocardial infarction（AMI） according to their clinical types. Another 41 stable angina patients with more than 70% of coronary artery tenosis who did not receive PCI served as control. Serum Hs-CRP levels and WBC count were determined before intervention, 3 days and 7 days post PCI and the data were analyzed statistically by t-test. Results： There showed no difference in clinical baseline characteristics between groups. The serum Hs-CRP level and WBC count was gradually raised in the UAP and AMI group（how about SAP group, andhad no difference in CAG group and SAP group）. After PCI serum HsCRP levels and WBC counts were significantly higher in the SAP group than in the coronary angiography group（CAG） at 3 days and had no difference at 7 days. In the UAP and AMI group, the serum Hs-CRP level at 3 days and 7 days declined obviously, however serum WBC count did not decrease apparently. Conclusion： The serum Hs-CRP level and WBC count elevate transiently after PCI. There are different inflammatory reactions in different types of coronary heart diseases after coronary stenting procedure.

Very Early C-Reactive Protein Levels after Acute Myocardial Infarction Predict Early Outcome and Late Prognosis

Objectives: C-reactive protein (CRP) blood levels are associated with atherosclerosis and increased incidence of coronary events. Aim: To evaluate the utility for risk stratification of very early blood CRP levels, during the first 6 hours after the onset of chest pain, in patients with acute myocardial infarction (AMI). Methods: 118 patients with AMI, 88 men, age 63.3 ± 8 yrs, were evaluated, and CRP was assessed within the first 6 hours after the onset of chest pains. Results: CRP level in all patients was 15.7 ± 14.1 mg/L. Its level increased with higher Killip class, 11.2 ± 5 mg/L in class 1, and 62 ± 7 mg/L in class 4 (p 40% (p < 0.01). Higher CRP values were found in patients with 3 vessel coronary artery diseases 20.7 ± 8 mg/L, vs. 8.7 ± 4 mg/L with 2 and 1 vessel disease (p < 0.05). Patients with in-hospital complications had higher CRP, 33.7 ± 10 mg/L vs. 12.1 ± 5 mg/L in those without (p < 0.001). Eight patients died at one-year follow-up. The CRP levels on admission in patients who died during the first year of follow-up, 45.2 ± 7.7 mg/L were higher than those in the survivors without adverse events, 11.6 ± 5 mg/L (p < 0.001). Admission CRP level in patients re-admitted with unstable angina, re-infarction or those who had coronary bypass surgery was similar to that in those who were not. Conclusions: Very early blood CRP levels in patients with AMI predict functional capacity, systolic left ventricular function, extent of coronary artery disease, early and short term complications and 1-year mortality but not recurrent myocardial ischemic events.

Combination of high-sensitivity C-reactive protein and homocysteine may predict an increased risk of coronary artery disease in Korean population

Background The association of emerging biomarkers such as high-sensitivity C-reactive protein （hs-CRP）,homocysteine and fibrinogen with the risk of coronary artery disease （CAD） is still uncertain in Asian population including Koreans and little is known about the combined effect of biomarkers on the risk of CAD.Methods A total of 10 650 subjects （6538 men and 4112 women） were enrolled in this study.A 10-year CAD risk was calculated using Framingham risk score modified by the National Cholesterol Education Program （NCEP） Adult Treatment Panel Ⅲ （ATP Ⅲ ） and levels of circulating hs-CRP,homocysteine and fibrinogen were measured using validated assays.Results The 10-year CAD risk gradually augmented with increase in the circulating levels of hs-CRP,homocysteine and fibrinogen.For the highest quartile of hs-CRP,odds ratio （OR） of high-risk for CAD （10-year risk ≥20%） compared with the lowest quartile was 3.97 （95% C/：2.51-6.29）.For homocysteine and fibrinogen,ORs in the highest quartile compared to the lowest quartile were 5.10 （95% Cl：3.05-8.53,P 〈0.001） and 1.46 （95% Cl：0.69-3.11,P=0.325）,respectively.OR of high-risk for CAD in both the highest quartile of hs-CRP and homocysteine was 9.05 （95% CI：5.30-15.45） compared with the below median of hs-CRP and homocysteine.Conclusions The present study demonstrated that hs-CRP and homocysteine are well associated with the 10-year CAD risk estimated using NCEP ATP Ⅲ in Koreans and combination of hs-CRP and homocysteine can have strong synergyin predicting the development of CAD.

High sensitive C-reactive protein, adiponectin, and urine albumin excretion rate in Chinese coronary artery disease patients with different glucose tolerance status

Background Serum high sensitive C-reactive protein （hs-CRP）, adiponectin levels and urine albumin excretion rate （UAER） are probably associated with inflammation and atherosclerosis. The aim of this study was to determine the three markers in coronary artery disease （CAD） subjects with different glucose tolerance status in a Chinese population and further explore the levels of the three markers in these subjects and the possible association of these markers with CAD risk factors and the severity of CAD as well. Methods A total of 242 subjects with angiographically documented CAD were recruited, and then assigned to three groups： the normal glucose tolerance （NGT） ＋ CAD group, including 100 CAD patients with NGT; the impaired glucose tolerance （IGT） ＋ CAD group, 40 CAD patients with IGT; the type 2 diabetes mellitus （T2DM） ＋ CAD group, 102 CAD patients with T2DM. Serum hs-CRP, adiponectin levels as well as UAER were measured in all subjects. Results Serum hs-CRP levels were increased in the T2DM ＋ CAD group compared with the NGT ＋ CAD group （4.71±2.59） vs （3.60±2.46） mg/L, P=0.037. Serum adiponectin levels were gradually decreased from the NGT ＋ CAD to IGT ＋ CAD to T2DM ＋ CAD groups, （5.99±1.84）, （5.82±1.72） and （4.65±1.71） mg/L, P=0.002 and 0.040 for NGT ＋ CAD and IGT ＋ CAD groups vs T2DM ＋ CAD group, respectively. While the UAER was gradually increased from the NGT ＋ CAD to IGT ＋ CAD to T2DM ＋ CAD groups, （6.42±2.51）, （6.89±2.94） and （15.03±4.22） μg/min （P 〈0.001） for NGT ＋ CAD and IGT ＋ CAD groups vs T2DM ＋ CAD group. Multiple linear stepwise regression analysis showed that waist-hip ratio （WHR） and low density lipoprotein cholesterol （LDL-C） were the significant determinants of serum hs-CRP levels; triglyceride （TG）, high density lipoprotein cholesterol （HDL-C）, age, WHR, T2DM, 2-hour serum insulin （2hINS）, sex, and apolipoprotein B were the significant determinants of serum adiponectin levels; and systolic blood pressure （SBP）, T2DM and hemoglobin A1c （HbA1c） were the significant determinants of UAER in all subjects （R^2= 0.070, 0.352, and 0.214, respectively）. However, no significant correlation was seen for hs-CRP, adiponectin and UAER with the severity of CAD. Hs-CRP levels were significantly correlated with UAER. Conclusions There was a trend of increased serum hs-CRP levels from the NGT ＋ CAD to IGT ＋ CAD to T2DM ＋ CAD groups, though it only showed significance in the T2DM ＋ CAD group compared with the NGT ＋ CAD group. Serum adiponectin levels were decreased and UAER was increased from the NGT ＋ CAD to IGT ＋ CAD to T2DM ＋ CAD groups Increased UAER and serum hs-CRP, and decreased adiponectin levels were associated with traditional CAD risk factors but failed to be correlated with the severity of CAD. Hs-CRP levels were significantly correlated with UAER.

Association between C-reactive protein gene ＋1059 G/C polymorphism and the risk of coronary heart disease： a meta-analysis

Background C-reactive protein （CRP） gene ＋1059 G/C polymorphism has been reported to be associated with coronary heart disease （CHD） risk, but the results remain inconclusive. This meta-analysis was therefore conducted to clarify these controversies. Methods A comprehensive search was conducted to identify all case control studies on the association between CRP gene ＋1059 G/C polymorphism and CHD risk. All the related studies were further strictly selected according to the inclusion criteria. Meta-analysis was performed with STATA 10.1 （StataCorp, USA）. The association was assessed by odds ratio （OR） and 95% confidence interval （C/）; both Begg＇s funnel plot and Egger＇s regression test were used to assess the publication bias. Results This meta-analysis on a total of 13 studies comprising 6316 CHD cases and 4467 controls showed no significant association between CRP gene ＋1059 G/C polymorphism and CHD risk in the overall study （for C/C＋C/G vs. G/G： OR=1.01, 95% C/=0.81-1.25, P=0.96; for C/C vs. C/G＋G/G： OR=1.17, 95% C/=0.77-1.77, P=0.47; for C/C vs. G/G： 0R=1.17, 95% C/=0.77-1.77, P=0.47; for C allele vs. G allele： 0R=1.01, 95% C/=0.81-1.24, P=-0.96）. However, in the subgroup analysis by ethnicity, the results showed significant association between CRP gene ＋1059 G/C polymorphism and CHD risk among Caucasians （for C/C vs. G/G： OR=2.54, 95% C1=1.13-5.72, P=0.02; C/C vs. C/G＋G/G： OR=2.45, 95% C1=1.09-5.51, P=-0.03）, but not among Asians and Africans （P 〉0.05）. Conclusion CRP gene ＋1059 G/C polymorphism may be associated with increased CHD risk among Caucasians and more evidences need to validate the conclusion.

Percutaneous panvascular intervention in an unusual case of extensive atherosclerotic disease

It is common to see patients with atherosclerotic coronary disease and peripheral arterial disease in routine clinical practice. One needs to have a comprehensive and integrated multi-speciality approach and panvascular revascularization in such patients. We report a 54-year-old diabetic hypertensive male with extensive atherosclerotic coronary and peripheral arterial disease, who presented with congestive heart failure, claudication of both lower limbs and mesenteric ischemia. He underwent successful percutaneous panvas- cular revascularization of coronary, renal, mesenteric, aorto-iliac and superficial femoral arteries. Long-term patency of all the stents was also documented.

Relationship between coronary atherosclerosis plaque characteristics and high sensitivity C-reactive proteins, interleukin-6

Background The relationship between inflammatory markers and the characteristics of coronary atherosclerosis plaques is uncertain. The aim of the present study was to evaluate the relationship between the characteristics of coronary atherosclerosis plaques and inflammatory markers such as high sensitivity C-reactive proteins （Hs-CRP） and interleukin-6 （IL-6）. Methods All patients suspected of having coronary heart disease （CHD） underwent Siemens 64-slice CT angiography （64-SCTA） to distinguish the quality of plaque of coronary artery lesions. Blood samples were taken to measure levels of serum Hs-CRP and IL-6 in different plaque groups and the control group and compared with the value of 64-SCTA for detection of coronary artery plaque. Results The sensitivity of detecting coronary artery plaque by 64-SCTA was 87.4%, the specificity was 87.1%, the positive predictive value was 82.2%, and the negative predictive value was 91.0%. Comparing the levels of serum Hs-CRP and IL-6 among plaque groups, the mean levels of serum Hs-CRP and IL-6 in three plaque groups were significantly higher than those in the control group （P 〈0.01）. The mean levels of serum Hs-CRP and IL-6 in the soft plaque group and mixed plaque group were significantly higher than those in hard plaque group （P〈0.01）. Plaque burden in the soft plaque group and mixed plaque group was significantly higher than in the hard plaque group （P 〈0.01）, but there was no statistical difference between the soft plaque group and mixed plaque group （P=-0.246）. There was a negative correlation between the CT scale and Hs-CRP and IL-6 levels in the soft plaque group （r= -0.621, P〈0.01, and r= -0.593, P 〈0.01 respectively）. There was a positive correlation between the plaque burden and Hs-CRP and IL-6 levels in the soft plaque group （r=0.579, P〈0.05 and r=0.429, P〈0.05 respectively）. Conclusions 64-SCTA is an effective way to distinguish the different quality of coronary atherosclerosis plaque. Serum Hs-CRP and IL-6 levels can be considered as the indexes to judge the degree of CHD and may reflect the activity of plaque in CHD patients. Thus it is important for clinical diagnosis and risk evaluation of acute coronary syndrome （ACS） patients.

Clinical Study on Effect of Garlicin in Stabilizing the Carotid Artery Atherosclerotic Plaque in Patients with Primary Hypertension and Coronary Artery Disease

Objective： To investigate the effect of garlicin in treating carotid artery atherosclerotic plaque （OAAP） in patients with primary hypertension and coronary heart disease （PHT-OHD）. Methods： Seventynine patients with PHT-OHD were randomly divided into the treated group （39 patients） treated with garlicin and fosinopril and the control group （40 patients） treated with fosinopril alone. The change of OAAP was evaluated by high frequency ultrasonic examination every six months, and the changes of intercellular adhesion molecule-1 （IOAM-1） and high sensitive O-reactive protein （hs-ORP） were measured by ELISA, with the observation proceeding for 52 weeks totally. Results： By the end of the experiment, the number of complex plaques, Orouse integrals, intima-media thickness, serum IOAM-1 and hs-ORP were significantly lower in the treated group than those in the control group with significant difference （P〈0.05）. Conclusion： Garlicin could stabilize CAAP to a certain extent and shows a definite vascular protective effect in patients with PHT-CHD.

髓过氧化物酶与超敏C反应蛋白在预警急性冠脉综合征中的价值比较（英文）

Background:High-sensitivity C-reactive protein(hs-CRP)is a major factor for predicting acute coronary syndrome(ACS).Myeloperoxidase(MPO)also plays an important role in atherosclerosis initiation and development.In the present work,a detail comparison between MPO and hs-CRP for early warning ACS is discussed.Objective:To compare the values between MPO and hs-CRP for early warning ACS and predicting major adverse cardiovascular events(MACEs)in CHD patients.Methods:MPO,hs-CRP and ACS-related risk factors from 201 ACS and 210 non-ACS patients were tested,and data were analyzed with SPSS software.Major adverse cardiovascular events(MACEs)were investigated during the 4-year period follow-up in 285 coronary heart disease(CHD)patients.Results:The areas under receiver operating characteristic(ROC)curve for diagnosing ACS were 0.888(95%CI 0.843-0.933)for MPO,and 0.862(95%CI 0.815-0.910)for hs-CRP,respectively.Compared to hs-CRP,MPO had more correlations strongly with ACS-related risk factors of TG,HDL-C and LDL-C in ACS patients(p<0.05).Prospective study demonstrated that the incidences of MACEs associated significantly with elevated MPO baseline level(yes vs no,OR 7.383,95%CI 4.095-13.309)and high hs-CRP baseline level(yes vs no,OR 4.186,95%CI 2.469-7.097).Conclusions:MPO as inflammatory marker for early warning ACS has some advantages compared to hsCRP.Elevated baseline MPO and hs-CRP levels are both valuable predictors of MACEs in CHD patients.
