Effect of sodium phosphocreatine on myocardial protection of patients with paroxysmal supraventricular tachycardia by treatment of radiofrequency catheter ablation

    摘要
  • 摘要: 目的：评价磷酸肌酸钠对阵发性室上性心动过速（PSVT）经导管射频消融术（RFCA）的心肌保护作用。方法选择2012年6月-2013年11月在本院心血管内科行 RFCA 的 PSVT 患者40例，随机分成磷酸肌酸钠组（SPC 组）和生理盐水组（NS 组），每组20例。SPC 组于术前1 d 开始给予 SPC 1 g 加入生理盐水250 mL 静脉滴注，NS 组则每日给予等量生理盐水静脉滴注，2组疗程均为3 d。检测2组患者术前及术后72 h 内血清中肌酸激酶（CK）与其同工酶（CK-MB）及肌钙蛋白 T（cTn T）的含量变化，并记录用药相关不良反应。结果与 NS 组相比，SPC 组在 RFCA 术后24 h 内及峰值血清 CK、CK-MB 及 cTn T 含量均显著降低（P ＜0．05），三者达峰时间及恢复术前水平的时间2组差异均无统计学意义（P ＞0．05）。未观察到与用药相关的不良反应。结论SPC 对 PSVT 患者行 RFCA 术后心肌具有一定的保护作用。

     

    Abstract: Objective To explore the effect of sodium phosphocreatine (SPC)on myocardi-al protection of patients with paroxysmal supraventricular tachycardia (PSVT)by treatment of radiofre-quency catheter ablation (RFCA).Methods 40 patients with PSVT by treatment of RFCA were ran-domly divided into SPC group (daily intravenous drip of 1 g SPC in 250 ml of normal saline,n =20) and NS group (the same volume of NS only,n =20).Assessment parameters that serum creatine ki-nase (CK),creatine kinase isoenzyme-MB (CK-MB)and cardiac troporin T (cTn T)were temporally investigated from pre-to 72 h after RFCA.Additionally,SPC-related adverse events were recorded. Results Compared with NS group,the overall and peak serum CK,CK-MB and cTn T significantly decreased in SPC group (P <0.05)during 24 hours after RFCA.No SPC-related adverse events were observed.Conclusion SPC shows a myocardial protective effect in patients with PSVT by treatment of RFCA.
