This paper is aimed at studying the adverse reactions of breast cancer patients after chemotherapy with different doses of adriamycin. Methods. 122 breast cancer patients undergoing mastectomy in the Haining Central Hospital from June 2018 to June 2020 were selected as the research objects. Patients were divided into control group and study group according to the different dose of adriamycin given to patients during chemotherapy. Patients in the control group received intravenous drip of adriamycin at 50\u2009mg\/m2. Patients in the study group were given intravenous drip at 75\u2009mg\/m2. Patients in both the groups started intravenous drip of cyclophosphamide 500\u2009mg\/m2 on the first day of chemotherapy, and chemotherapy for 21 days was a cycle. A total of 6 cycles were carried out. Abnormal electrocardiograph (ECG) is compared between the two groups. Myocardial enzyme and oxidative stress indicators were tested, and Doppler ultrasound examination was conducted. Results. After chemotherapy, the abnormal rate of ECG in the study group was 56.46%, which was significantly higher than that in the control group (46.67%). After chemotherapy, the indexes of myocardial enzymes and oxidative stress increased, while superoxide dismutase (SOD) decreased significantly, and the differences were statistically significant. At the end of chemotherapy, the differences of serum myocardial enzymes and oxidative stress indexes in the study group were higher than those in the control group. After chemotherapy, there was no significant difference between left ventricular ejection fraction (LVEF) and Sa in the study group and the control group, but Ea in the study group was higher than that in the control group and E\/Ea was lower than that in the control group. Conclusion. High-dose adriamycin chemotherapy is more likely to cause accumulation of cardiotoxicity, resulting in decreased cardiac function and cardiac injury in breast cancer patients.<\/jats:p>","DOI":"10.1155\/2022\/1642244","type":"journal-article","created":{"date-parts":[[2022,2,15]],"date-time":"2022-02-15T22:50:06Z","timestamp":1644965406000},"page":"1-5","source":"Crossref","is-referenced-by-count":6,"title":["Analysis of Cardiac Adverse Reactions Caused by Different Doses of Adriamycin Chemotherapy in Patients with Breast Cancer"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2421-0075","authenticated-orcid":true,"given":"Guangwen","family":"Hu","sequence":"first","affiliation":[{"name":"Department of Cardiology, Haining Central Hospital, Haining, Zhejiang 314400, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daxin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Yangzhou University, Yangzhou, Jiangsu 225000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1186\/s13063-017-2140-z"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.5603\/CJ.a2020.0062"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdx773"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.26355\/eurrev_201804_14752"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2016.05.001"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1186\/s12916-015-0439-8"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.3390\/jcm9051268"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.tips.2015.03.005"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1111\/echo.14622"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v8.i12.2542"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.phymed.2019.152921"},{"issue":"7","key":"12","first-page":"2862","article-title":"Research progress of cardioprotective agents for prevention of anthracycline cardiotoxicity","volume":"8","author":"J.
