CRISPR Technology Fixes Genetic Heart Problems

Bacteria chop up invading viruses using CRISPR, now adapted to edit human DNA with incredible precision. Last year, researchers corrected a mutation causing hypertrophic cardiomyopathy in lab-grown heart cells. Many patients with this condition need pacemakers. Clinical trials now aim to edit genes to prevent arrhythmia entirely, potentially eliminating the need for implanted devices. This approach addresses the genetic root causes of heart rhythm disorders rather than just managing symptoms.
