Advances in oncologic therapies have allowed to achieve better outcomes and longer survival in many patients with breast cancer. Anthracyclines are cytotoxic antibiotics widely used in daily oncology practice. However, anthracyclines cause cardiotoxicity which is a limiting factor of its use. Cumulative dose of anthracyclines is the major cause of induced cardiotoxicity. According to previous clinical trials, the major predisposing high-risk factors for anthracycline-based chemotherapy-induced cardiotoxicity are age, body weight, female gender, radiotherapy, and other diseases such as diabetes and hypertension. Experimental studies in animals confirm that hypertension may be a significant factor predisposing anthracycline-based chemotherapy cardiotoxicity. The main objective of our study was to identify the effect of pre-existing arterial hypertension on the development of subclinical cardiac damage during or after doxorubicin-based chemotherapy in breast cancer patients. The study was performed prospectively between March 2016 and January 2017 in the Hospital of Lithuanian University of Health Sciences Kaunas Clinics Department of Oncology and Department of Cardiology. Data of 73 women with breast cancer treated with doxorubicin-based chemotherapy in outpatient clinic were analyzed. Statistically significant association between pre-existing arterial hypertension and left ventricular systolic dysfunction after completion of chemotherapy was observed (P < 0.004). Our study demonstrated that pre-existing arterial hypertension has a very important role in the development of anthracycline-based chemotherapy-induced cardiotoxicity, despite arterial hypertension control quality. Consequently, further studies evaluating impact of other risk factors and how early and sufficient management of arterial hypertension could influence the development of cardiotoxicity are needed to avoid permanent cardiac damage.
