Analysis of Early Monitoring for Heart Damage Caused by Anthracyclines Chemotherapy Drugs after Breast Cancer Surgery / 中国药房

ABSTRACT

OBJECTIVE:To investigate the early changes of ECG,cTnⅠ,LDH,α-HBDH and CKMB in patients with anthra-cyclines chemotherapy-induced heart damage after breast cancer surgery,and to explore their significances in the diagnosis of early heart damage. METHODS:Medical information of 152 cases of anthracyclines chemotherapy after breast cancer surgery in our hos-pital during Jan. 2015-Jun. 2016 were analyzed retrospectively. According to diagnosis criteria of drug-induced cardiotoxicity,the occurrence of heart damage was evaluated during hospitalization and 1-year follow-up. According to evaluation results,those pa-tients were divided into heart damage group(50 cases)and control group(102 cases). The early changes of ECG,cTnⅠ,LDH, CKMB and α-HBDH were analyzed before chemotherapy(T0),24 h after first chemotherapy(T1),24 h after second chemothera-py(T2),24 h after forth chemotherapy. RESULTS:At T1,T2,T3,the proprotion of ECG abnormalities in heart damage group was significantly higher than control group;the serum levels of cTnⅠ,LDH,CKMB andα-HBDH in heart damage group were signifi-cantly higher than control group, with statistical significance (P<0.01). CONCLUSIONS:For anthracyclines chemotherapy drugs-induced heart damage after breast cancer surgery,early regular monitoring of ECG,cTnⅠ,LDH,CKMB and α-HBDH can improve the efficiency of early diagnosis of heart damage,and improve prognosis.
