Key result
Advanced radiation techniques, post-therapy screening, and cardioprotective medications may mitigate radiation-induced cardiomyopathy.
Why the study?
Radiation-induced cardiomyopathy has become a significant clinical challenge with the increased use of thoracic radiation therapy.
Comprehensive strategies including advanced radiation techniques, mitigation methods, and pharmacological agents like statins and ACE inhibitors are crucial for preventing and managing radiation-induced cardiomyopathy.
May support cardioprotective strategies during radiation therapy; leaves open confirmation in prospective trials before practice change.
Radiation-induced cardiomyopathy has become a significant clinical challenge with the increased use of thoracic radiation therapy. Recent technological advancements in radiation therapy, such as 3D conformal radiation therapy (3D-CRT), intensity-modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT), and proton therapy, have decreased cardiac exposure. Additional methods including multileaf collimation (MLC) cardiac shields, patient prone positioning, and the deep inspiration breath-hold (DIBH) technique further mitigate the effects of radiation on the heart. Post-therapy cardiac screening is crucial for timely intervention. Furthermore, the antioxidant properties of certain medications and herbal supplements may counteract radiation-induced oxidative stress. Notably, statins, angiotensin converting enzyme inhibitors, and natural products have demonstrated protective effects against radiation-induced cellular damage. This review is aimed at illuminating RIC pathophysiology, clinical implications, and management strategies to enhance early detection, treatment, and prevention.
