High-Precision Radiation Therapy Reduces Life-Threatening Heart Arrhythmias by 80%
Mayo Clinic researchers have demonstrated that proton beam therapy, a highly targeted noninvasive radiation treatment, reduced episodes of ventricular tachycardia by nearly 80% in critically ill patients with few remaining treatment options. The first-in-human early feasibility study represents the first large-scale evidence for using targeted radiation to treat this dangerous, fast heart rhythm disorder that can lead to sudden cardiac death. The findings were presented as late-breaking research at the Heart Rhythm Society conference on April 26 and published in the Heart Rhythm Journal. This breakthrough could offer a new therapeutic approach for patients suffering from life-threatening cardiac arrhythmias who have exhausted conventional treatment options.
Proton beam therapy study results and effectiveness
