【摘要】 为观察急性心肌梗塞（ＡＭＩ）时血液凝固与纤溶系统的变化，动态测定２８例ＡＭＩ患者３０天内的ＡＴ－ⅢＡｇ、Ｆｎ、ＦＤＰ值，与正常组、心绞痛组进行对比分析，结果ＡＴ－ⅢＡｇ、Ｆｎ，在发病７２小时内明显降低，ＦＤＰ在３０天内明显上升，均变化显著。提示ＡＴ－ⅢＡｇ出现早、变化敏感，是体内主要的抗凝物质；Ｆｎ变化与病情一致，可做为ＡＭＩ病情和治疗监测的项目；ＦＤＰ持续久，变化显著，对溶解血栓与防止血栓再形成有重要意义。综合测定上述指标，有利于指寻ＡＭＩ的治疗和康复更多还原

【Abstract】 To study the change of bolld Coagulation and fiberprotein dissolving system in AMI,AT-ⅢAg,Fn,and FDP in 28 cases with AMI were consecutively measured in 30 day onset.compared with those in nomal controls and in angina pectoris patients.AT-ⅢAg and Fn in AMI cases decreased significantly with in 72 hour onset,while FDP in AMI increased markedly daring 30 day onset.In conclusion,AT-ⅢAg was on important anti coagulating substance and was characterized by ealy occurance and high sensitivity.The change of Fn accorded with the seriousness of AMI.The augment of FDP could lost long time and be essential in preventing thrombosis or thromnbolizing.更多还原
