Heart attack damage reversed with injectable RNA therapy, study finds

Scientists have developed a new therapy designed to repair cardiac damage after a heart attack.The study, led by researchers at Columbia University and published in the journal Nature Biomedical Engineering, explored a two-step strategy that uses skeletal muscle to produce a healing molecule that activates when it reaches an injured heart.Unlike many organs, the adult human heart has a limited ability to repair itself after a heart attack, the r…

This Simple Injection Could Help The Heart Heal Itself After a Heart Attack

A new RNA-based therapy for heart repair could fundamentally change how doctors treat heart attack damage, turning a routine injection into a kind of biological “repair signal” for the heart. Developed by researchers at Columbia University School of Engineering and Applied Science, the experimental treatment doesn’t just prevent further injury. It aims to help the heart rebuild itself, a feat long considered out of reach in modern cardiology. Wh…
