Percutaneous coronary intervention (PCI) in patients with angiographic evidence of intracoronary thrombus is associated with in-hospital and 30-day adverse clinical outcomes. Cangrelor, a direct, rapid-onset acting intravenous P2Y receptor inhibitor, has been proved to be effective by reducing peri-PCI ischemic complications in subjects who underwent PCI. This study aimed to assess the angiographic and in-hospital clinical outcomes in all-comer patients receiving cangrelor immediately before PCI at a tertiary care center. The study analyzed consecutive unselected subjects treated with cangrelor at the time the decision was made to proceed with PCI. At the end of the procedure, all patients were transitioned to oral antiplatelet therapy. The target lesion angiographic assessment of Thrombolysis in myocardial infarction flow grade (TIMI-Flow), TIMI-thrombus grade (TIMI-Thrombus), myocardial blush grade, and TIMI-myocardial perfusion grade (TMPG) was performed before and post-PCI. Clinical events were recorded during the procedure and at discharge. In total, 223 patients (244 lesions) were included in the analysis (106, 97, and 20 patientswith TIMI-Flow 0/1, TIMI-Flow 2/3, and cardiogenic shock, respectively). The overall mean age was 63 ± 12 years, 70% men and 38% with diabetes mellitus. Acute myocardial infarction was the main presentation (72%). The use of cangrelor improved TIMI-Flow, MGB, TMPG, and TIMI-Thrombus in patients with initial TIMI-Flow 0 to 2. Major bleeding rate was 2.0%. In conclusion, cangrelor was effective and safe in restoring TIMI-Flow 3, reducing thrombus burden and improving myocardial blush grade and TMPG when administered to unselected subjects who underwent PCI. Therefore, cangrelor should be considered in patients presenting with intracoronary thrombus before intervention.
经皮冠状动脉介入治疗(PCI)患者有冠状动脉内血栓形成的血管造影证据与住院和 30 天不良临床结局相关。坎格雷洛是一种直接、快速起效的静脉 P2Y 受体抑制剂,已被证明可通过减少接受 PCI 的患者围 PCI 缺血性并发症而有效。本研究旨在评估在三级保健中心接受 PCI 前立即接受坎格雷洛治疗的所有患者的血管造影和住院临床结局。该研究分析了在决定进行 PCI 时接受坎格雷洛治疗的连续非选择性患者。在手术结束时,所有患者均转为口服抗血小板治疗。在 PCI 前后进行了心肌梗死溶栓血流分级(TIMI-Flow)、TIMI 血栓分级(TIMI-Thrombus)、心肌染色分级和 TIMI 心肌灌注分级(TMPG)的靶病变血管造影评估。术中及出院时记录临床事件。共纳入 223 例患者(244 处病变)进行分析(TIMI-Flow 0/1 为 106 例,TIMI-Flow 2/3 和心源性休克分别为 97 例和 20 例)。总体平均年龄为 63 ± 12 岁,70%为男性,38%患有糖尿病。主要表现为急性心肌梗死(72%)。坎格雷洛的使用改善了初始 TIMI-Flow 为 0 至 2 的患者的 TIMI-Flow、MGB、TMPG 和 TIMI-Thrombus。主要出血率为 2.0%。总之,坎格雷洛在未选择接受 PCI 的患者中恢复 TIMI-Flow 3、降低血栓负荷以及改善心肌染色分级和 TMPG 时是有效且安全的。因此,对于存在冠状动脉内血栓的患者,在干预前应考虑使用坎格雷洛。
