An 86-year-old man successfully underwent percutaneous coronary intervention (PCI), in which a drug-coated stent (DCS) was placed in the left anterior descending coronary artery. However, stent thrombosis occurred twice after eight and two months. After the second admission, the patient was tested for platelet aggregation activity using the platelet aggregation threshold index (PATI), and insufficient inhibition of platelet aggregation was observed. The patient's PATI improved to a satisfactory level using oral anticoagulants. At the six-month follow-up, clinical events were observed. Measuring the platelet aggregation ability can help clinicians understand the pathology of patients and determine treatment choices.
一位 86 岁男性成功接受了经皮冠状动脉介入治疗(PCI),在左前降支冠状动脉内植入了药物涂层支架(DCS)。然而,在 8 个月零 2 天后,支架内血栓形成了两次。第二次入院后,患者使用血小板聚集阈值指数(PATI)检测血小板聚集活性,观察到血小板聚集抑制不足。患者口服抗凝剂后 PATI 改善至满意水平。在 6 个月的随访中,观察到临床事件。测量血小板聚集能力有助于临床医生了解患者的病理,并确定治疗选择。
