RESUMO
Objective :To study influence of cardiac rehabilitation combined routine treatment on cardiac function and ECG in patients with ischemic cardiomyopathy (ICM).Methods :A total of 108 ICM patients treated in our hospital from Jul 2013 to May 2017 were randomly and equally divided into routine treatment group and cardiac rehabilitation group (received cardiac rehabilitation therapy based on routine treatment group ) ,both groups were treated for eight weeks .LVEF ,left ventricular fractional shortening (LVFS) ,QT dispersion (QTd) ,T peak‐T end interval (Tp‐e) before and after treatment ,and therapeutic effect were observed and compared between two groups .Results :Total effective rate of cardiac rehabilitation group was significantly higher than that of routine treatment group (87. 0%vs.75.9%) , P＝0.043. Compared with before treatment ,there were significant rise in LVEF and LVFS ,and sig‐nificant reductions in QTd and Tp‐e in two groups after eight‐week treatment (except Tp‐e of routine treatment group) , P＜0.05 or ＜0.01. Compared with routine treatment group after treatment ,there were significant rise in LVEF [(42.3 ± 5.8)% vs.(49.8 ± 6.5)%] and LVFS [(25.6 ± 6.1)% vs.(35.2 ± 6. 9)%] ,and significant reduc‐tions in QTd [ (52. 3 ± 6. 3) ms vs .(45. 2 ± 7. 1) ms] and Tp‐e [ (129.7 ± 12. 5) ms vs.(118. 5 ± 13.0) ms] in car‐diac rehabilitation group ,P＝0.001 all.Conclusion :Cardiac rehabilitation combined routine treatment possesses sig‐nificant therapeutic effect on ICM patients .It can significantly improve cardiac function .
