Abstract：Objective To analyze the characteristics and prognosis of impure tachycardia-induced cardiomyopathy (iTCM).Methods All 57 iTCM patients who were admitted in hospital from 2003 to 2011 were assigned to the research group,and 70 dilated cardiomyopathy patients (DCM) were as a control group.Results After the treatment,heart rate,N-terminal pro-B-type natriuretic peptide original (NT-ProBNP),left ventricular end-diastolic diameter (LVDd),left ventricular ejection fraction in research group were all improved [(77 ± 30) times/min vs (138 ± 42) times/min,(705 ± 103) ng/L vs (5423 ± 1017) ng/L,(53 ± 8) mm vs (62 ± 16) mm,(58 ± 10) ％ vs (39 ± 14) ％,respectively,P ＜ 0.05 or P ＜ 0.01].Heart rate,NT-ProBNP,LVDd,left ventricular ejection fraction in control group were also improved[(81 ± 18) times/min vs (92 ± 20) times/min,(1270 ± 320) ng/L vs (6750 ± 1300) ng/L,(58 ± 11) mm vs (64 ± 15) mm,(42 ± 11) ％ vs (38 ± 13) ％,respectively,P ＜ 0.05 or P ＜0.01].At follow-up,9 cases (15.8％) composite endpoints were observed in research group,which were lower than that in control group [38.6％ (27/70),P ＜ 0.01].Conclusion After arrhythmia is controlled,the heart structure and function can be improved remarkably in iTCM patients,showing a better prognosis than that in DCM patients.
