Methods: Sixty-five patients, with coronary artery disease, were enrolled and divided into three subgroups: acute myocardial infarction (AMI), unstable angina pectoris (UAP) and SAP, and 26 healthy people were recruited as controls in the cross-sectional study. Serum resistin levels were determined by ELISA (enzyme-linked immunosorbent assay), and WBC (white blood cell count), hsCRP (high sensitive C-reaction protein), CKmax (maximum of creatinkinase), CK-MBmax (maximum of isozyme of creatinkinase) and cTnImax (maximum of troponin) were measured by standard laboratory methods. Results: The serum resistin levels were 4 folds higher in AMI patients, 2.43 folds in UAP patients and 1.12 folds in SAP patients than in the healthy controls (P<0.05). The resistin levels were also significantly different between AMI [(8.16±0.79) ng/ml], UAP [(5.59±0.75) ng/ml] and SAP [(3.45±0.56) ng/ml] groups (P<0.01); WBC, hsCRP, CKmax, CK-MBmax and cTnImax were significantly increased in AMI patients over UAP and SAP patients. Spearman analysis showed that serum resistin levels were positively correlated with WBC (r=0.412, P=0.046), hsCRP (r=0.427, P=0.037), CKmax, CK-MBmax and cTnImax (r=0.731, 0.678, 0.656; P<0.01). Conclusion: Serum resistin levels increased with inflammatory factors and myocardial impairment. The results suggest that human resistin might play an important role in the pathogenesis of atherosclerosis and AMI as an inflammatory factor.展开更多

Methods： Sixty-six patients with SAP confirmed by coronary angiography were enrolled and assigned to two groups by means of PROC PLAN using a SAS 6.12 software in a double-blinded, randomized, placebo-controlled design. Patients in the treated group were treated with SST, and the others in the control group were given placebo. The weekly angina frequency, quality of life scale [Seattle Angina Questionnaire （SAQ）] and incidence of important clinical events were observed to evaluate the intervention effect of SST on the quality of life for CHD patients with SAP. Results： During the study, one case dropped out in the treated group and two cases in the control group, respectively, and 63 cases including 32 cases in the treated group, and 31 cases in the control group completed the trial. After four weeks of treatment, the weekly angina frequency of the treated group （5.32± 2.46 times per week） was significantly less than that of the control group （7.32± 3.20 times per week, P 〈 0.05）. The total score of the quality of life in the treated group （71.30± 5.44） was obviously higher than that in the control group （63.50± 4.60, P 〈 0.01）, and the angina stability, angina frequency, and treatment satisfaction were significantly superior to those in the control group （P〈 0.01）. The incidence of important clinical events of the treated group （3.1%） was lower than that of the control group （6.5%） during the six-month follow-up period, but the difference was insignificant （P 〉 0.05）. Conclusion： SST could lower the angina frequency and greatly improve the quality of life in CHD patients with SAP.展开更多

Such lesions are identified by positive remodeling （intravascular ultrasound （IVUS） and complex lesions （angiography））. The prevalence of lesions with vulnerable characteristics in patients with stable angina was not well known. The purpose of the present study was to evaluate the relationship between coronary artery remodeling and incidence of angiographic complex lesions and its calcification in stable angina patients.Methods One hundred and sixty-one stable angina patients （95 males, aged （68±11） years） with 161 de novo target lesions were studied using pre-interventional IVUS. Remodeling index was defined as the lesion divided by reference vessel area; positive remodeling was defined as remodeling index 〉1.05. Besides the 161 target lesions, there were 613 angiographic lesions with 〉30% diameter stenoses, classified as complex or smooth. Multiple complexes were defined as more than one complex lesion in one patient. Stenoses of at least 70% were described as tight. Calcium arc area was used as a new method to quantify coronary calcification.Results Fifty-six patients had positive remodeling target lesion, while 105 did not. The overall number of lesions with a diameter stenoses 〉30% was similar in patients with or without positive remodeling, and the frequency of angiographically complex lesions was higher in positive remodeling patients, especially at non-target site. Calcium arc area was smaller in patients with positive remodeling.Conclusions Positive remodeling on intravascular ultrasound was associated with more complex lesions angiographic findings, especially at non target site. Positive remodeling was found less calcified in patients with stable angina.展开更多

C-reactive protein(CRP)and albumin are indicators of inflammation.And both of them are associated with high SS. Hence,we aimed to investigate whether baseline CRP to albumin ratio(CAR)is associated with SS. Method A total of 312 consecutive patients with stable angina pectoris,who underwent coronary angiography for suspected coronary artery disease(CAD)from January 2018 to May 2019,were classified into two groups,low score group(syntax score≤22)and high score group(syntax group>22).The Multivariate logistic analysis and ROC curve were performed to detect the predictive effect of CAR for higher SS. Results There are 163 cases in the low score group while 149 cases in the high score group. CAR in the high score group was significantly higher than the other group(5.6[2.8-9.6]vs. 2.5[1.7-5.2],P<0.01). In multivariate logistic regression analysis,CAR was proved to be an independent predictor for high syntax score. ROC curve analyses reveal the good predictive values of CAR(AUC 0.731,95% CI:0.608-0.814,P<0.01)for high syntax score and statistical significant better than CRP or albumin alone. Conclusions CAR is independently associated with the complexity and severity of CAD,which has better predictive value than CRP or albumin alone.展开更多

文摘Background:As an acute phase protein,α1-antitrypsin (AAT) has been extensively studied in acute coronary syndrome,but it is unclear whether a relationship exists between AAT and stable angina pectoris (SAP).The purpose of the present study was to investigate the association between AAT plasma levels and SAP.Methods:Overall,103 SAP patients diagnosed by coronary angiography and clinical manifestations and 118 control subjects matched for age and gender were enrolled in this case-control study.Plasma levels of AAT,high-sensitivity C-reactive protein (hsCRP),lipid profiles and other clinical parameters were assayed for all participants.The severity of coronary lesions was evaluated based on the Gensini score (GS) assessed by coronary angiography.Results:Positively correlated with the GS (r =0.564,P ＜ 0.001),the plasma AAT level in the SAP group was significantly higher than that in the control group (142.08 ± 19.61 mg/dl vs.125.50 ± 19.67 mg/dl,P ＜ 0.001).The plasma AAT level was an independent predictor for both SAP (odds ratio [OR] =1.037,95％ confidence interval [CO:1.020-1.054,P ＜ 0.001) and a high GS (OR =1.087,95％ CI:1.051-1.124,P ＜ 0.001) in a multivariate logistic regression model.In the receiver operating characteristic curve analysis,plasma AAT level was found to have a larger area under the curve (AUC) for predicting a high GS (AUC =0.858,95％ CI:0.788-0.929,P ＜ 0.001) than that of hsCRP (AUC =0.665,95％ CI:0.557-0.773,P =0.006; Z =2.9363,P ＜ 0.001),with an optimal cut-off value of 137.85 mg/dl (sensitivity:94.3％,specificity:68.2％).Conclusions:Plasma AAT levels correlate with both the presence and severity of coronary stenosis in patients with SAP,suggesting that it could be a potential predictive marker of severe stenosis in SAP patients.
文摘ackground Development of vulnerable lesions is not limited to the target lesions, but a pan-coronary process. Such lesions are identified by positive remodeling （intravascular ultrasound （IVUS） and complex lesions （angiography））. The prevalence of lesions with vulnerable characteristics in patients with stable angina was not well known. The purpose of the present study was to evaluate the relationship between coronary artery remodeling and incidence of angiographic complex lesions and its calcification in stable angina patients.Methods One hundred and sixty-one stable angina patients （95 males, aged （68±11） years） with 161 de novo target lesions were studied using pre-interventional IVUS. Remodeling index was defined as the lesion divided by reference vessel area; positive remodeling was defined as remodeling index 〉1.05. Besides the 161 target lesions, there were 613 angiographic lesions with 〉30% diameter stenoses, classified as complex or smooth. Multiple complexes were defined as more than one complex lesion in one patient. Stenoses of at least 70% were described as tight. Calcium arc area was used as a new method to quantify coronary calcification.Results Fifty-six patients had positive remodeling target lesion, while 105 did not. The overall number of lesions with a diameter stenoses 〉30% was similar in patients with or without positive remodeling, and the frequency of angiographically complex lesions was higher in positive remodeling patients, especially at non-target site. Calcium arc area was smaller in patients with positive remodeling.Conclusions Positive remodeling on intravascular ultrasound was associated with more complex lesions angiographic findings, especially at non target site. Positive remodeling was found less calcified in patients with stable angina.

文摘Objective To assess the clinical effectiveness of acupoint application(AP)of Guan Xin Su He Pill(冠心苏合丸,GXSHP)for patients with chronic stable angina pectoris(CSAP).Methods This study was carried out in 3 local hospitals in Chengdu,China.After baseline evaluation,eligible patients were randomly assigned to the placebo application for acupoints(PAA)group or the herbal application for acupoints(HAA)group.Patients in the HAA group underwent AP with herbal powder,which was mainly GXSHP,and patients in the PAA group underwent AP with sham drugs.For each treatment session,unilateral acupoints including Neiguan(PC 6),Danzhong(RN 17),Xinshu(BL 15)and Jueyinshu(BL 14),were stimulated for both groups.AP was performed 3 times a week with a 2-day interval for 4 weeks.The primary outcome was the frequency of angina pectoris attacks per week,while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale(VAS),dose of rescue oral drugs(nitroglycerin),scores on the Seattle Angina Questionnaire(SAQ),Self-Rating Anxiety Scale scores(SAS)and Self-Rating Depression Scale scores(SDS).Clinical outcomes were measured at week 0,4 and 8.The safety of AP of GXSHP treatment for CSAP were assessed.Results A total of 121 patients were enrolled.Baseline characteristics were comparable across the 2 groups.After treatment,the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81(P<0.05).While,for PAA group,the angina frequency was not significantly improved(baseline 10.55;post-treatment 11.05).The HAA group had significantly fewer angina attacks than the PAA group(P<0.05).Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02(P<0.05).While,for PAA group,the VAS was significantly increased(baseline 3.62;post-treatment 3.96;P<0.05).Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs,SAS,SDS and SAQ scores(P<0.05).The adverse events were also reported.Conclusion AP of GXSHP is a safe and effective treatment for CSAP patients(Registration No.NCT02029118).

文摘Background Syntax score(SS),an angiographic tool to grade the complexity of coronary artery disease,has prognostic importance for this disease. C-reactive protein(CRP)and albumin are indicators of inflammation.And both of them are associated with high SS. Hence,we aimed to investigate whether baseline CRP to albumin ratio(CAR)is associated with SS. Method A total of 312 consecutive patients with stable angina pectoris,who underwent coronary angiography for suspected coronary artery disease(CAD)from January 2018 to May 2019,were classified into two groups,low score group(syntax score≤22)and high score group(syntax group>22).The Multivariate logistic analysis and ROC curve were performed to detect the predictive effect of CAR for higher SS. Results There are 163 cases in the low score group while 149 cases in the high score group. CAR in the high score group was significantly higher than the other group(5.6[2.8-9.6]vs. 2.5[1.7-5.2],P<0.01). In multivariate logistic regression analysis,CAR was proved to be an independent predictor for high syntax score. ROC curve analyses reveal the good predictive values of CAR(AUC 0.731,95% CI:0.608-0.814,P<0.01)for high syntax score and statistical significant better than CRP or albumin alone. Conclusions CAR is independently associated with the complexity and severity of CAD,which has better predictive value than CRP or albumin alone.
