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

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.
