| 1 | Altered serum level of cartilage oligomeric matrix protein and its association with coronary calcification in patients with coronary heart disease显示文摘BackgroundCartilage oligomeric 矩阵蛋白质(COMP ) 主要在骨胳的系统和脉管的光滑的肌肉房间被发现。最近的研究证明它在血容器上有保护的功能并且能也禁止脉管的石灰化。我们在冠的心疾病( CHD )调查了浆液 COMP 病人,并且在浆液 COMP 和首先经历了多片跟随的冠的 angiography 的 233 个连续的胸疼痛病人全部的冠的 artery.MethodsA 的石灰化之间的关系在六个月以内计算了断层摄影术( MSCT )被招募并且根据缩小百分比的冠的 angiography 钠直径划分了成二个组:CHD 组(缩小 50% 的直径, n = 194 ) 并且控制组(直径变窄 <50% , n = 39 ) 。Gensini 分数,句法分数和冠的动脉钙分数(CAC ) 是计算的。浆液 COMP 水平用 COMP 的 ELISA.ResultsThe 层次被决定比在控制组在 CHD 组是显著地更高的 155.7 (124.5-194.5 ) ng/mL 对 128.4 (113.0-159.9 ) ng/mL, P = 0.019。在 COMP, Gensini 分数,句法分数,冠的狭窄的严厉和有狭窄的冠的动脉的数字之间没有关联 >50% 。浆液 COMP 与年龄被相关(r = 0.294, P < 0.001 ) , fasting 葡萄糖(r = 0.163, P = 0.015 ) , HbA1c (r = 0.194, P = 0.015 ) 并且 CAC (r = 0.137, P = 0.037 ) 。逐步的线性回归分析显示出那 COMP 水平,年龄是在 CHD 病人的 CAC 的独立预言者(= 0.402, t = 2.612, P = 0.015;= 0.472, t = 3.077, P = 0.005 ) 。为预言 CHD 的 COMP 的性能在曲线(AUC ) 下面作为区域被显示出:0.632, 95% CI:0.549-0.715 和上面的 tertile CAC 是 AUC:0.602, 95% CI:在操作冠的动脉的特征(巨鸟) 曲线 analysis.ConclusionCalcification 的接收装置的 0.526-0.678 是浆液 COMP 的一个独立预言者。 | Fang-Fang WANG Lahati HA Hai-Yi YU Lin MI Jiang-Li HAN Wei GAO | 2017 | Journal of Geriatric Cardiology2017，14，2： | 15 |
| 2 | Association between serum cartilage oligomeric matrix protein and coronary artery calcification in maintenance hemodialysis patients显示文摘Background Coronary artery calcification(CAC)is common in end-stage renal disease(ESRD)patients,and the extent of CAC is closely related to cardiovascular outcomes in ESRD patients.Cartilage oligomeric matrix protein(COMP),as a component of the vascular matrix,has been found to be an inhibitor of arterial calcification in basic studies.However,there is no clinical research on the correlation between COMP and CAC in maintenance hemodialysis(MHD)patients.The aim of this study was to explore the relationship between serum COMP levels and CAC and cardiovascular events in MHD patients.Methods Serum COMP levels were compared between 54 MHD patients and 66 healthy people.MHD patients were then divided into three groups according to the tertiles of the concentration of COMP level and were followed up for major adverse cardiac events(MACEs),which were defined as a combined end point of new onset angina pectoris,nonfatal myocardial infarction,heart failure,coronary artery revascularization,hospitalization due to angina pectoris and all-cause deaths.The CAC score was calculated based on computed tomography scans.Results The serum COMP level in MHD patients was significantly higher than that in the general population[984.23(248.43-1902.61)ng/mL vs.219.01(97.26-821.92)ng/mL,P<0.01].Serum COMP levels were positively correlated with CAC(r=0.313,P=0.021)and serum parathyroid hormone in MHD patients(r=0.359,P<0.01).Linear regression suggested that after adjusting for age,fasting blood glucose(Glu)and glycosylated hemoglobin(HbAlc),CAC score was an independent predictor in the final model for COMP level(β=0.424,t=3.130,P<0.01).The receiver operating characteristic(ROC)curve showed that COMP≥994 mg/mL had 68.0%sensitivity and 72.4%specificity for the prediction of severe CAC[area under the curve(AUC):0.674,P=0.030,95%CI:0.526-0.882].After a median follow-up of 16 months(8-24 months),there was no difference in the incidence rate of MACEs between the upper,middle and lower serum COMP groups.Conclusions Our study found that MHD patients have higher levels of circulating COMP than controls.The serum COMP level is positively correlated with CAC score and could be used as a biomarker of severe CAC in MHD patients.However,there is no obvious correlation between serum COMP levels and the incidence of cardiovascular events. | Lahati HA Jun-Bao SHI Hai-Yi YU Kun YANG Hai-Ning WANG Fang-Fang WANG Jiang-Li HAN | 2020 | Journal of Geriatric Cardiology2020，17，2： | 11 |
| 3 | A case of applying left bundle branch pacing combined with atrioventricular node ablation to treat atrial fibrillation-induced heart failure显示文摘The core treatment of rapid arrhythmiainduced heart failure(HF)is to control the ventricular rate to an optimized lower level,which is usually achieved with various anti-arrhythmic drugs.However,arrhythmias may not respond well to pharmaceutical treatment for various reasons.Iatrogenic atrioventricular(AV)node ablation needs to be performed under these extreme conditions to lower the patient’s heart rate. | Lahati HA Li-Yun HE Lei LI Jiang-Li HAN Shu-Wang LIU Yuan ZHANG Wei XU Wei GAO | 2021 | Journal of Geriatric Cardiology2021，18，6： | 4 |
