冠状动脉支架术对定量心肌血流和健康状况的影响
研究概览
详细说明
心肌灌注成像 (MPI) 在疑似或已知冠状动脉疾病 (CAD) 患者的诊断、风险分层和预后方面具有公认的作用 (1,2)。 随着当前的医疗保健格局朝着有价值的方向发展,确定影像学检查在改善以患者为中心的结果中的作用的紧迫性越来越高 (3-5)。 传统上,心脏成像界一直专注于研究“硬结果”,例如心脏病发病率和死亡率,而对以患者为中心的健康状况结果(例如, 症状、功能和生活质量)。
虽然单光子发射计算机断层扫描 (SPECT) 几十年来一直是心肌灌注成像 (MPI) 的支柱,但正电子发射断层扫描 (PET) MPI 的使用一直在增加,因为它提供更高的空间分辨率、更低的辐射暴露、更高的诊断准确性、更短的时间心肌血流储备 (MBFR) (6-9) 的采集时间和量化。 MBFR 整合了微血管功能障碍、弥漫性动脉粥样硬化疾病和心外膜狭窄对心肌组织灌注的血流动力学影响,因此更可能与患者的心绞痛症状、功能状态和生活质量相关 (10,11)。 通过 PET MPI 测量的 MBFR 已被证明可为灌注缺陷分析之外的主要不良心脏事件提供独立和增量的预后价值,但尚未评估其与症状、功能和生活质量的关联(尽管在事后分析中171 名接受 PET MPI 的已知 CAD 患者参加了我们中心的 ASPIRE 研究,根据西雅图心绞痛问卷(SAQ;未发表的数据,在 ASNC 2018 上发布)测量,较高的 MBFR 与较低的心绞痛负荷显着相关(8,10 ,12-15). 在 329 名患者中,Taqueti 等人证明,与药物治疗相比,如果通过旁路手术而不是经皮冠状动脉介入治疗 (PCI) 进行早期血运重建治疗,则总体 MBFR 较低的患者需要后续心力衰竭住院治疗和心源性死亡的可能性较小;然而,事件数量少和样本量小是主要的限制因素 (10)。 最近,在接受 PET MPI 的 12,594 名患者中,我们证明了 MBFR <1.8 可能有助于确定在指数 MPI 测试后 90 天内从早期血运重建中获得生存益处的患者。 (未发表的数据,在 AHA 2018 上展示)。 在 PACIFIC 研究的子研究中,Driessen 等人表明血运重建后 MBFR 的变化与 FFR 的变化有很强的相关性;进一步支持无创测量 MBFR 作为目标干预的潜在措施,类似于 FFR,这需要对冠状动脉造影进行有创测量 (16)。
为了进一步阐明 MBFR 可用于靶向治疗缺血性心脏病的作用机制,我们建议对 75 名接受冠状动脉支架置入术的患者进行连续 PET MPI 研究,以评估 MBFR 变化与患者健康状况变化的关联. 大约四分之一到一半接受 PCI 治疗的稳定 CAD 患者在支架置入后仍存在心绞痛和生活质量差 (17-19) 这可能是因为支架置入仅针对心外膜狭窄,而许多患者伴有微血管疾病。 虽然有一些数据表明,系列 PET MPI 研究已被用于观察灌注缺损大小的变化以及抗缺血药物和他汀类药物的流量 (20-24),但尚不清楚这些变化是否与改善的结果相关。 我们建议在支架置入前后对患者进行 PET MPI 研究,以评估 MBFR 的变化(或缺乏),以及它与症状、功能状态和生活质量的变化(或缺乏)之间的关系。 这将有助于了解 MBFR 在选择冠状动脉造影和支架置入术患者中的作用。
