- The study examined long-term cardiovascular risk in women receiving contemporary external beam radiation therapy (EBRT) for left-sided versus right-sided breast cancer.
- No significant difference was found in the 15-year cumulative incidence of first cardiovascular disease hospitalization between left-sided (13.8%) and right-sided (13.5%) radiation.
- For women with preexisting CVD, left-sided EBRT showed slightly higher rates of new heart failure and ischemic heart disease diagnoses compared to right-sided EBRT.
- Recurrent CVD hospitalization rates were modestly higher in left-sided cases (1.72 vs. 1.63 per 100 person-years).
- Left-sided breast radiation therapy was associated with minimal increases in long-term cardiovascular risk, indicating modern techniques have reduced historical risks.
