Background: Breast cancer is the most prevalent malignancy in females which needs chemotherapy treatment. Studies demonstrated that anti-cancer agents used for chemotherapy in cancer patient causes endothelium dysfunction. Several researches showed the efficacy of angiotensin-converting enzyme inhibitors, Carvedilol and Spironolactone on improving endothelial function. This study aimed to evaluate the effect of the combination of Spironolactone, Carvedilol, and Captopril on endothelial function in breast cancer patients.
Materials and methods: This study is a prospective Randomized Clinical Trial in breast cancer patients who underwent chemotherapy. Patients were divided into two groups who received the combination of Captopril, Spironolactone, and Carvedilol or standard regimen for 3 months during chemotherapy. Before and after intervention, ejection fraction (EF), E/A ratio and e' and flow-mediated dilation (FMD) properties were calculated and then compared.
Results: Fifty-eight patients with a mean age of 47.57 ± 9.46 years were evaluated. The mean FMD after the intervention is statistically different in case and controls (<0.001). E/A ratio and e' are not statistically different between groups after intervention. The mean EF was not statistically different between the two groups after intervention.
Conclusion: Prescribing combination of Carvedilol, Spironolactone, and Captopril in breast cancer patients undergoing chemotherapy can improve endothelial function and may have beneficial effects on diastolic function.
