冠状动脉介入治疗的主要并发症为急性冠状动脉闭塞。尽管在冠状动脉介入治疗中常规应用大量肝素抗凝,但20％～50％的急性冠状动脉闭塞是由于冠状动脉内血栓形成,而且这种血栓形成也是冠状动脉介入治疗后再狭窄机理之一。作者检测了冠状动脉介入治疗后病人冠状窦内血清抗肝素凝血酶原活性及其与各种并发症的关系。
The main complication of coronary intervention is acute coronary occlusion. Although heparin anticoagulation is routinely used in coronary interventions, 20% to 50% of acute coronary occlusions are due to coronary thrombosis and this thrombosis is also one of the mechanisms of restenosis after coronary intervention. The authors examined the anti-heparin prothrombin activity in patients with coronary sinus after coronary intervention and its relationship with various complications.
