Choosing antithrombotic therapy for patients at high bleeding risk, particularly those requiring long-term anticoagulant therapy, who have acute coronary syndromes (ACS) and/or undergoing percutaneous coronary intervention (PCI) is becoming increasingly complex.
A 78-year-old women was hospitalized with chest pain and a diagnosis of non-ST-elevation ACS was made. It was decided that the patient should undergo coronary angiogram with a view for angioplasty. Subsequently, she underwent successful PCI to the left anterior descending artery. Shortly after PCI, she was noted to be in atrial fibrillation. Furthermore, she had per rectal bleeding and acute kidney injury, which were managed conservatively. Aspirin and ticagrelor were stopped and she was discharged on dual antithrombotic therapy with clopidogrel and apixaban.
Available evidence, driven mainly from expert consensus documents, advocates a case-by-case comprehensive evaluation that integrates patient- and procedure-related factors to assess patients for thrombotic and bleeding tendencies to identify those who may gain most net clinical benefit of antithrombotic combination therapy. In general, if thrombotic drivers prevail, an augmented antithrombotic regime with a view for a longer duration should be planned, and if bleeding drivers prevail, a de-escalated regime with a view for a shorter duration should be sought.
为高出血风险患者,尤其是那些需要长期抗凝治疗、患有急性冠状动脉综合征(ACS)和/或正在接受经皮冠状动脉介入治疗(PCI)的患者选择抗血栓治疗正变得越来越复杂。
一名78岁女性因胸痛入院,诊断为非ST段抬高型ACS。决定该患者应接受冠状动脉造影以进行血管成形术。随后,她成功接受了左前降支的PCI。PCI后不久,发现她出现房颤。此外,她有直肠出血和急性肾损伤,对其进行了保守治疗。停用阿司匹林和替格瑞洛,她出院时接受氯吡格雷和阿哌沙班的双联抗血栓治疗。
现有证据主要来自专家共识文件,主张进行逐案综合评估,整合患者和手术相关因素,以评估患者的血栓形成和出血倾向,从而确定那些可能从抗血栓联合治疗中获得最大净临床益处的患者。一般来说,如果血栓形成因素占主导,应计划采用强化抗血栓方案并延长疗程,如果出血因素占主导,则应寻求采用降级方案并缩短疗程。
