A Higher Mean Heart Radiation Dose Induces Higher Frequency of Multiple Cardiac Changes.

Background/aim: Radiotherapy (RT) induces late changes in all cardiac structures. Most studies of early changes focus on individual parameters.

Patients And Methods: Data from eighty early-stage breast cancer patients at baseline, post-RT and three-year follow-up visit were assessed prospectively.

Radiotherapy-induced Early ECG Changes and Their Comparison with Echocardiography in Patients with Early-stage Breast Cancer.

Background: Early electrocardiogram (ECG) changes after breast cancer radiotherapy (RT) have been reported, but their characteristics and associated factors are largely unknown. This study aimed to explore early RT-induced ECG changes and to compare them with echocardiography changes.

Materials And Methods: Sixty eligible patients with chemotherapy-naïve left-sided and 20 with right-sided breast cancer were evaluated with echocardiography, blood samples and ECG before and after RT.
