Immune protein promotes arrhythmias after heart attacks
Researchers at Massachusetts General Hospital have identified an immune protein that damages heart cells after a myocardial infarction, leading to dangerous arrhythmias. By targeting this protein in mice, the team reduced arrhythmia incidents twelvefold. The findings suggest new ways to prevent sudden cardiac death.
