Radiation-induced myocardial perfusion abnormalities in breast cancer patients following external beam radiation therapy

摘要

Objective(s):Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer.
