No Association Between Left-Breast Radiation Therapy or Breast Arterial Calcification and Long-Term Cardiac Events in Patients with Breast Cancer

摘要

Background: Recent studies have suggested an association between radiation therapy (RT) of the left breast and increased incidence of coronary artery disease. However, the increased sparing afforded with modern RT may decrease long-term cardiac risk. The aims of our study were to evaluate the association between the RT and cardiac events in breast cancer patients who underwent contemporary RT and to examine whether breast arterial calcification (BAC) seen on mammogram predicts for cardiac events.
