Nanotechnology could spur new heart treatment for arrhythmia (University of Michigan Health System)

(Source: University of Michigan Health System) ANN ARBOR - A new nanoparticle developed by University of Michigan researchers could be the key to a targeted therapy for cardiac arrhythmia , a condition that causes the heart to beat erratically and can lead to heart attack and stroke. The disease affects more than four million Americans and causes over 750,000 hospitalizations and 130,000 deaths per year in the United States alone. The new treatment uses nanotechnology to precisely target and destroy the cells within the heart that cause cardiac arrhythmia. In studies conducted on rodents and sheep, the U-M team found that the treatment successfully kills the cells that cause cardiac...
