Dr. David G Kirsch and colleagues developed and characterized a mouse model of radiation-induced heart disease that mimics the dose, fractionation, and beam arrangement of left breast and chest wall radiation therapy. [02Feb2021 Radiother Oncol.] ​​​​​​​

Highlights

  • Cardiac function was preserved in wild-type mice after 50 Gy fractionated partial-heart RT.
  • ApoE -/- mice on a regular diet showed subtle RIHD after 50 Gy by PV loop analysis.
  • PV loop analysis is a useful addition to SPECT and echo especially for subtle RIHD.
