摘要
目的:探讨老年不稳定性心绞痛(UA)患者血管性血友病因子(vWF)与可溶性血管细胞间粘附分子-1(sVCAM-1)水平变化及其与心肌缺血的关系。方法:采用酶联免疫吸附法(ELISA),检测了50例健康人和73例UA(自发性心绞痛27例,心肌梗死后心绞痛25例,恶化劳力性心绞痛21例)患者血浆vWF、sVCAM-1浓度的变化。结果:①UA患者血浆vWF水平、sVCAM-1浓度[(2.47±0.88)%、(1.92±0.51)%、(961±58)μg/L、(692±73)μg/L],明显高于对照组[(572±58)μg/L、(0.96±0.14)%](P<0.01);②心绞痛发作时vWF、sVCAM-1浓度增高较缓解后更明显(P<0.01);③心绞痛发作时和缓解后,sVCAM-1与vWF呈正相关(r=0.785,r=0.674,P<0.01);④不同类型的心绞痛发作时和缓解后sVCAM-1、vWF浓度差异亦具有显著性(P<0.01);⑤自发性心绞痛患者vWF、sVCAM-1增高较心肌梗死后和恶化劳力性心绞痛更明显。结论:急性心肌缺血与vWF和sVCAM-1异常有一定关系。
AIM: To explore the changes of von Willebrand factor (vWF) and soluble vascular- cellular adhesion molecule- 1 (sVCAM- 1), and the correlation of vWF, sVCAM- 1 with acute myocardial ischemia. METHODS: By means of enzyme linked immunosorbent assay (EIJSA), the changes of vWF and sVCAM - 1 were measured in 73 patients with unstable angina (UA) during angina attack and relief period (24 h after attack) as well as in 50 controls. RESULTS: The levels of vWF and sVCAM - 1 were significantly higher in UA patients than those in controls ( P 〈 0.01 ). The increase in vWF and sVCAM - 1 in angina attack was more obvious than those in relief period ( P 〈 0.01 ). vWF correlated positively with sVCAM - 1 ( r = 0.785, r = 0.674, P 〈 0.01 ). In different types of angina, there were significant difference of vWF, sVCAM - 1 between angina attack and relief periods ( P 〈 0.01 ), and increases in all the indicators in spontaneous angina patients were more obvious than those in exertional and postinfarction angina patients. CONCLUSION: Acute myocardial ischemia might be related to the changes of vWF and sVCAM- 1.
