摘要:
目的 探讨血流储备分数(fractional flow reserve,FFR)指导下经皮冠状动脉介入(percutaneous coronary intervention,PCI)治疗对急性冠状动脉综合征(acute coronary syndrome,ACS)多支血管病变患者指导效果及对不良事件的影响。 方法 回顾性分析2019年4月至2020年4月昆明市第一人民医院心内科收治的320例ACS合并多支血管病变患者应用随机数字表法均分为2组,每组160例。即采用血流储备分数指导下行(PCI)治疗(FFR组)和单纯冠状动脉造影(CAG)指导下行PCI治疗(CAG组)。比较2组患者基本资料、PCI成功率、支架植入数量等的差异。术后随访6个月,比较2组患者主要不良心血管事件(MACE)的发生情况。 结果 2组患者基本资料比较,差异无统计学意义(P > 0.05);2组PCI成功率、PCI手术时间、住院时间比较,差异无统计学意义(P > 0.05);FFR组支架植入数量、造影剂使用量少于CAG组(P < 0.05);术后6个月,2组靶血管血运重建、不良心血管事件总发生率比较差异无统计学意义(P > 0.05)。 结论 FFR指导下行PCI治疗能够减少不必要的支架植入,降低主要不良心血管事件的发生,改善ACS合并多支血管病变患者的预后。 -

Abstract:Objective To investigate the effect of percutaneous coronary intervention (PCI) under the guidance of FFR on the guidance of patients with the acute coronary syndrome (ACS) with multi-vessel disease and the effect on adverse events. Methods A total of 320 patients with ACS complicated with multi-vessel disease admitted to the Department of Cardiology, of the First People’ s Hospital of Kunming city from April 2019 to April 2020 were divided into 2 groups by random number table method, with 160 patients in each group. PCI was guided by blood flow reserve fraction (FFR group) and PCI was guided by coronary angiography (CAG group). The differences in the basic data, success rate of PCI and the number of stent implantation between the two groups were compared. The incidence of major adverse cardiovascular events (MACE) was compared between the two groups after 6 months of the follow-up. Results There was no significant difference in the basic data between the two groups (P > 0.05); There was no statistical significance in the success rate of PCI, duration of PCI operation and length of hospital stay between 2 groups (P > 0.05); The number of stent implanted and the amount of contrast agent used in FFR group were lower than those in CAG group (P < 0.05); 6 months after the surgery, there was no significant difference in the total incidence of target vessel revascularization and adverse cardiovascular events between the two groups (P > 0.05). Conclusion Downward PCI guided by FFR can reduce the unnecessary stent implantation, reduce the occurrence of major adverse cardiovascular events, and improve the prognosis of patients with ACS complicated with multi-vessel disease. -
