目的研究汉族冠心病患者血浆中组织因子活性(aTF)、活化凝血因子VII(FVIIa)和凝血因子VII抗原(FVII:Ag)水平并探讨其与冠脉病变支数之间的关系。方法aTF采用发色底物法,FVIIa和FVII:Ag采用ELISA法。结果与对照组相比,冠心病患者血浆中aTF(P<0.05)、FVIIa(P<0.01)及FVII:Ag(P<0.05)水平均显著升高;急性冠状动脉综合征(ACS)患者中aTF高于稳定型心绞痛(SAP)组(P<0.05)和对照组(P<0.01),后两者之间无显著差异;ACS和SAP患者之间血浆中FVIIa水平无显著差异,但均高于对照组;ACS组中FVII:Ag水平明显高于对照组。在不同冠脉病变支数的患者之间,aTF、FVIIa及FVII:Ag水平没有差异。结论SAP和ACS患者均可出现外源性凝血途径的激活,血浆中aTF增强可能预示了急性冠脉事件的发生;FVIIa可能可以作为冠心病的早期分子标志物;冠脉病变支数可能不能反映凝血激活的程度。 相似文献

目的:探讨血尿酸(UA)水平与冠心病(CHD)病变严重程度及与心血管事件的相关性。方法:回顾性分析于我院行冠脉造影403例患者的临床资料,其中308例CHD患者[稳定型心绞痛(SAP ,137例)、急性冠脉综合征(ACS ,171例)],95例非CHD患者(正常对照组),比较各组间UA水平的差异,并进一步分析其与冠脉病变严重程度的相关性。再根据UA水平CHD患者被分为低尿酸组(147例)和高尿酸组(161例),经12个月随访,比较两组随访期间主要不良心血管事件(MACE)的发生率。结果:ACS组血 UA水平显著高于正常对照组[(318.44±69.07)μmol/L比(295.38±80.08)μmol/L ,P=0.003];随着冠脉病变支数的增加及冠脉病变程度的加重(Gensini评分增高),血UA水平呈显著升高趋势[单支(316.58±95.27)μmol/L比双支(335.26±43.26)μmol/L比多支(346.53±86.74)μmol/L ;低分组(312.42±48.26)μmol/L比中分组(346.58±47.36)μmol/L比高分组(363.84±54.68)μmol/L , P<0.05或<0.01], Pearson相关分析显示,血UA水平与Gensini评分呈正相关(r=0.583, P<0.05);高尿酸组MACE发生率明显高于低尿酸组(58.38%比36.24%, P=0.012)。结论:血尿酸水平与冠心病严重程度呈正相关,可能为冠心病独立危险因素。 相似文献

目的探讨冠心病患者血浆巨噬细胞移动抑制因子(MIF)水平与冠状动脉粥样硬化病变的关系。方法根据选择性冠状动脉造影结果将142例患者分为冠心病组和对照组。冠心病组根据临床诊断分为稳定型心绞痛(SAP)和急性冠脉综合征(ACS)组;根据冠状动脉病变范围将冠心病组分为单支病变、双支病变和三支病变组。血浆MIF浓度通过ELISA法测定。结果冠心病组MIF水平明显高于对照组〔(14.97±4.11)vs(9.07±1.28)μg/L〕,ACS组MIF浓度又明显高于SAP组〔(16.66±3.56)vs(11.01±2.12)μg/L〕。随冠状动脉病变范围的增加,MIF浓度逐渐升高,各组间差异有显著统计学意义。结论MIF增高与冠状动脉粥样硬化发生显著相关,其可以做为预测冠状动脉粥样硬化病变情况的一个指标,与冠状动脉粥样硬化斑块不稳定关系更密切。 相似文献

We report the case of a 34-year-old female patient with a giant thrombus-filled aneurysm of the right coronary artery presenting as a spherical cardiac mass on echocardiography. The cardiac mass was found to be an 8-cm right coronary artery aneurysm on cardiac magnetic resonance imaging, which also revealed a 3.5-cm proximal left coronary aneurysm and a very small aneurysm at the origin of the obtuse marginal coronary artery. Due to the extent and size of the right coronary aneurysm, a decision for surgical intervention was made. Resection of the right coronary artery aneurysm with vein graft replacement and a bypass to the left anterior descending followed by subsequent exclusion of the aneurysm was successfully performed. 相似文献

A rare case of coronary anomaly is presented: all of the coronary arteries originated from a single ostium located in the right coronary cusp. No clinical evidence of coronary pathology was recognized until the age of 57 years when the patient was found to have coronary obstructive disease. The single coronary artery had a main branch corresponding to the usual dominant right coronary artery. Three other branches separated from this and vascularized the areas normally receiving the circumflex and ramus medianus, the left anterior descending, and a large septal branch. 相似文献

Two patients with chest pain had angiographically-demonstrated communications between the three coronary arteries and the left ventricular chamber. Communications between coronary arteries and the left ventricle are unusual and communications between all three coronary arteries and the left ventricle are rare. These anomalies are, however, commonly associated with symptoms of chest pain. The presence of left ventricular hypertrophy and a widened pulse pressure may suggest a greater hemo-dynamic effect of the shunt flow than often suspected angiographically. 相似文献

Seven patients with significant fixed occlusive coronary artery disease had coronary artery spasm in a “normal” vessel. All patients had one or more episodes of rest angina and six had exertional angina as well. Four sustained previous myocardial infarction. During spontaneous angina, five patients had ST-segment elevation in the inferior electrocardiographic leads. One patient had ST-segment elevation in anterior leads. During angiography, spasm was demonstrated in the right coronary artery in three patients and in the left anterior descending coronary artery in one patient. This study emphasizes the interaction of fixed and vasospastic disease and has strong implications concerning the management of patients with ischemic heart disease. 相似文献

Cine coronary arteriograms of 121 patients with normal coronary arteriograms with and without associated valvular or myocardial disease were reviewed to describe normal coronary artery anatomy and the distribution of potentially graftable vessels. Coronary arterio grams were divided into right, mixed, and left interior emphasis systems, depending upon the blood supply to the inferior surface of the left ventricle. Whether a coronary artery at its origin was less than 50%, between 50–70%, or greater than 70% of the left anterior descending coronary artery (LAD) at its origin was described in a simple lettering and numbering code to allow easy comparison. The diameter of the LAD at its origin averaged 4.2 mm. All vessels greater than 70% of the LAD were clearly graftable. The frequency (in percent) with which that vessel was greater than 70% of the LAD in right, mixed, and left systems, respectively, was as follows: This simple method of classification is recommended to provide more accurate comparison in published series and to assist the coronary arteriographer in his interpretations. 相似文献

This paper describes a case of dissection of the main stem of the left coronary artery during coronary angiography with an uneventful clinical course. As far as we know, only one comparable case has been reported before. A brief survey of the pertinent literature is presented. Some possible pathogenetic factors are considered. No specific preventive or therapeutic measurement can be recommended. 相似文献
