A new study published in the Journal of the American College of Carediology concluded that thoracic radiotherapy for lung cancer patients led to more than 10% of patients having heart attacks, heart failure, and other cardiac problems. Rates for those considered at high risk for cardiac problems were even higher for those with no history of cardiovascular disease.

In the study researchers evaluated data for 748 patients with non-small cell lung cancer and found a direct correlation between increaqsed dosages of heart radiation exposure and the riusk of cardiac problems. Researchers concluded that patients should receive lower dosages of radiation than national guidelines recomment and should be 10 gray units compared to 20. In addition, researchers recommended finding ways to mitigate the harmful effects of radiation.
