Background:Anthracyclines can improve survival in many types of malignancies, but
dose-dependent and irreversible results following the use of anthracyclines have been associated
with cardiomyopathy. This meta-analysis aimed to compare the effects of prophylactic agents for
preventing cardiotoxicity induced following anticancer agents.Methods:In this meta-analysis, Scopus, Web of Science, and PubMed were surfed for articles
published by December 30th, 2020. The keywords were angiotensin‐converting enzyme inhibitor
(ACEI), enalapril, captopril, angiotensin receptor blocker, beta blocker, metoprolol, bisoprolol,
isoprolol, statin, valsartan, losartan, eplerenone, idarubicin, nebivolol, dihydromyricetin, ampelopsin,
spironolactone, dexrazoxane, antioxidants, cardiotoxicity, n-acetyl-tryptamine, cancer, neoplasms,
chemotherapy, anthracyclines, doxorubicin, daunorubicin, epirubicin, idarubicin, ejection fraction or a
combination of them in the titles or abstracts.Results:A total of 17 articles out of 728 studies examining 2,674 patients were included in this
systematic review and meta-analysis. Ejection fraction (EF) values in the baseline, 6-month, and
12-month follow-up in the intervention group turned out to be 62.52 ± 2.48, 59.63 ± 4.85, and
59.42 ± 4.53, whereas in the control group appeared to be 62.81 ± 2.58, 57.69 ± 4.32, and 58.60 ±
4.58, respectively. Through comparison of the two groups, EF was found to increase in the
intervention group by 0.40 after 6 months (Standardized mean difference (SMD): 0.40, 95%
confidence interval (CI): 0.27, 0.54), thus proving higher than that of the control groups
following the cardiac drugs.Conclusion:This meta-analysis showed that prophylactic treatment with cardio-protective drugs,
including dexrazoxane, beta blocker, and ACEI drugs in patients undergoing chemotherapy with
anthracycline, have a protective effect on LVEF and prevent EF drop.
