Background Alteration in the protein composition of high-density lipoprotein (HDL) has been proposed as a mechanism for the development of coronary heart disease (CHD).In HDL,an increase in serum amyloid A protein (SAA) accompanying the decrease in apolipoprotein A-I (apoA-I) has been found during the acute inflammation period.However,whether this phenomenon persists in CHD patients,a disease related to inflammation,is unknown.The purpose of the present study was to explore the relationship between SAA and apoA-I in HDL isolated from CHD patients.Methods Overall,98 patients with confirmed stable CHD and 90 control subjects matched for age and gender were enrolled in this case-control study.Potassium bromide (KBr) density gradient ultracentrifugation was used to isolate HDL from plasma.The levels of SAA and apoA-I in the HDL samples were detected by enzyme-linked immunosorbent assay kits.Pearson's correlation and general linear models were used in the analysis.Results Compared with controls,patients with CHD had a significant decrease in the amount of apoA-I ((14.21±8.44) μg/ml vs.(10.95±5.95) μg/ml,P =0.003) in HDL and a significant increase in the amount of log SAA (1.21±0.46 vs.1.51±0.55,P 〈0.00001).Differences were independent of age,body mass index (BMI),HDL cholesterol (HDL-C),and other factors.An independently and statistically significant positive correlation between log SAA and apoA-I in HDL was observed only in the CHD group (β =2.0,P =0.026).In the general linear model,changes in Iog(SAA),age,age2,gender,BMI and HDL-C could explain a statistically significant 43% of the variance in apoA-I.Conclusions This study provides direct evidence for the first time that there was an independent positive correlation between log SAA and apoA-I in the HDL of CHD patients,indicating the alteration of protein composition in HDL.However,the question of whether this alteration in HDL is associated with impairment of HDL functions requires further research. 相似文献

Background Alteration in the protein composition of high-density lipoprotein (HDL) has been proposed as an emerging mechanism in the development of coronary heart disease (CHD). In HDL, an increase in serum amyloid A protein (SAA) accompanying the decrease in apolipoprotein A-I (apoA-I) has been found during the acute inflammation period. However, whether this phenomenon remains in CHD patients, another disease related to inflammation, is unknown. The purpose of the present study was to explore the relationship between SAA and apoA-I in HDL isolated from CHD patients.
Methods Overall, 98 patients with confirmed stable CHD and 90 control subjects matched in age and gender were enrolled in this case-control study. Potassium bromide (KBr) density gradient ultracentrifugation was used to isolate HDL from plasma. The levels of SAA and apoA-I in the HDL samples were detected by enzyme-linked immunosorbent assay kits. Pearson’s correlation and general linear models were used in the analysis.
Results Compared with controls, patients with CHD had a significant decrease in the level of apoA-I (14.21±8.44 µg/mL vs. 10.95±5.95 µg/mL, P =0.003) in HDL and a significant increase in the level of log(SAA) (1.21±0.46 vs. 1.51±0.55, P <0.00001) independently from age, BMI, HDL cholesterol (HDL-C), etc. An independently and statistically significant positive correlation between log(SAA) and apoA-I in HDL was observed only in the CHD group (β =2.0, P =0.026). In the general linear model, changes in log(SAA), age, age2, gender, BMI and HDL-C could explain a statistically significant 43% of the variance in apoA-I.
Conclusions This study provided direct evidence for the first time that there was an independently positive correlation between log(SAA) and apoA-I in the HDL of CHD patients, indicating the alteration of protein composition in HDL. However, the question of whether this alteration in HDL is associated with impairment of HDL functions requires further research.

Comparison of Diver CE and ZEEK manual aspiration catheters for thrombectomy in ST-segment elevation myocardial infarction 总被引:10,自引:0,他引:10
ZHAO Han-jun YAN Hong-bing WANG Jian SONG Li LI Qing-xiang LI Shi-ying CHI Yun-peng WU Zheng ZHANG Xiao-jiang ZHAO Yong ZHENG Bin 《中华医学杂志(英文版)》2009,122(6):648-654
Background A growing volume of data suggests that simple manual thrombus aspiration followed by direct stenting improves myocardial reperfusion and clinical outcome compared with conventional primary PCI, but there is still limited data comparing the in vivo performance among different devices. This study aimed to compare the efficacy and operability of thrombus aspiration by the Diver CE (Invatec, Brescia, Italy) and ZEEK (Zeon Medical Inc., Tokyo, Japan) aspiration catheters in ST-segment elevation myocardial infarction (STEMI) and their impact on 3-month outcome.
Methods From September 2004 to June 2008, 298 consecutive patients with STEMI who received manual thrombus aspiration were involved in a single center retrospective analysis. Of them, 229 and 69 were treated with Diver CE and ZEEK aspiration catheters, respectively. Primary endpoints were myocardial blush grade (MBG), thrombolysis in myocardial infarction (TIMI) flow grade, ST-segment elevation resolution (STR), device pushability and trackability as judged by the frequency of usage of dual guide wires and aspiration efficacy as indicated by size distribution of aspirated thrombi. Secondary endpoints were 3-month outcome including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), as well as cardiac death, target lesion revascularization (TLR), re-infarction and their combination as major adverse cardiac events (MACE). Results Baseline characteristics were not different between the two groups expect for a higher frequency of temporary cardiac pacing in the ZEEK group (ZEEK) than in the Diver CE group (Diver CE) (0.44% vs 5.8%, P=0.002). Visible retrieved thrombi were achieved in 65.9% of the Diver CE and 68.1% of the ZEEK (P=0.74). Aspirated thrombi were categorized as small thrombi (〈3.5 mm), moderate thrombi (3.5-7.0 mm) and large thrombi (〉7.0 mm). Small thrombi were more frequently seen in the Diver CE (61.6% vs 42.6%), whereas moderate and larger thrombi were more frequently found in the ZEEK (38.4% vs 57.4%) (P=0.021). Rates of dual wire utilization were 1.7% of the Diver CE and 7.2% of the ZEEK (P=0.052). There were no differences in MBG, STR and TIMI flow grade between the two groups. No differences were found in cardiac death, TLR, re-infarction, MACE, LVEDD and LVEF between the Diver CE and the ZEEK during 3-month follow-up.
Conclusions Both Diver CE and ZEEK manual aspiration catheters are effective for thrombectomy in STEMI. In clinical practice, ZEEK presents a stronger aspiration capacity for moderate to large thrombi compared with Diver CE, but Diver CE displays a trend towards better pushability and trackability than ZEEK. Differences in aspiration capacity and operability between Diver CE and ZEEK in this setting do not influence myocardial reperfusion and 3-month outcome. 相似文献

冠状动脉粥样硬化性心脏病是全球范围内心血管疾病患者死亡的主要原因,其中以急性ST段抬高型心肌梗死(STEMI)最为凶险。及时经皮冠状动脉介入治疗(PCI)是目前急性STEMI患者最主流的再灌注策略。而部分患者在PCI术后仍不能得到充分的血液灌注,即出现无复流现象(NRP),与随后的不良临床预后密切相关。因此,为了有效恢复再灌注后冠状动脉微循环的血流,防治冠状动脉NRP的发生就显得尤为重要。本文回顾NRP的定义、诊断和临床表现,以病理生理机制为桥梁,提出通过相关预测因子来选择防治策略从而提高PCI疗效。 相似文献

目的:探讨急性ST段抬高型心肌梗死(STEMI)早期阴离子间隙(AG)与院内死亡率的关系。方法:回顾性研究459例STEMI患者,分为AG升高组(AG≥16mmol/L,n=230)和AG正常组(AG<16mmol/L,n=229),对N端脑利钠肽前体(NT-proBNP)、肌钙蛋白I(TnI)、估算的肾小球滤过率(eGFR)和射血分数(EF)等进行分析;以院内是否发生死亡为因变量,进行Logistic回归分析,比较AG与年龄、性别、eGFR和EF的相关性。结果:两组性别、高血压、糖尿病、血脂异常、吸烟、家族史等差异均无统计学意义(均P>0.05)。与AG正常组相比,AG升高组的NT-proBNP和TnI升高(均P<0.05),eGFR和EF降低(均P<0.05),院内心力衰竭和死亡的发生率显著升高(均P<0.05)。Logisitic回归分析发现AG升高是STEMI患者早期院内死亡的独立危险因素(OR=1.179,95%CI:1.034~1.345,P=0.014)。结论:AG升高可增加STEMI患者院内心力衰竭和死亡风险,是STEMI早期评估预后的独立危险因素。 相似文献
