摘要 目的研究射频消融术(RFCA)导致局部心肌损伤及炎症反应的程度以及影响因素。方法 于RFCA术前及术后即刻、6h、24h测定34例接受RFCA治疗的阵发性室上性心动过速患者的血清白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF—α)、肌钙蛋白Ⅰ(cTn—Ⅰ)的活性。结果 34例患者均无并发症。IL一6、TNF—α及cTn—Ⅰ值均升高,术后6h达高峰水平,术后即刻、6h、24h与术前比较有统计学意义(P<0.01或0.05)。经相关分析表明:IL-6、cTn—Ⅰ活性变化的峰值升高程度与消融靶点个数、消融时间、平均功率、累积能量具有相关性(P<0.05)。结论射频消融可导致心肌损伤;同时伴有局部炎症反应的存在及发展。IL-6、TNF—α可作为监测RFCA术后心肌炎症反应的敏感指标。
