Radiation exposure linked to pulmonary hypertension after lung cancer treatment
Lung cancer patients undergoing radiation treatment may be at higher risk of developing pulmonary hypertension, a type of high blood pressure that affects the arteries that carry blood from the right side of the heart to the lungs. Over time, that heightened pressure can lead to right-sided heart failure.
Lung cancer patients undergoing radiation treatment may face an increased risk of developing pulmonary hypertension, a condition that causes high blood pressure in the arteries leading to the lungs, potentially resulting in right-side heart failure. Researchers from Cedars-Sinai Health Sciences University investigated how radiation exposure to the heart and lungs during lung cancer treatment contributes to the development of pulmonary hypertension.
The study, published in Thorax, identified a link between the radiation dose delivered to the pulmonary artery and the occurrence of pulmonary hypertension, but not to other areas of the heart or lungs. Out of the patients evaluated, 12% experienced pulmonary hypertension, leading to symptoms such as heart strain and shortness of breath.
The findings emphasize the need for heightened awareness and new guidelines for evaluating at-risk patients, as well as further research into the issue.
