Gene therapies designed to strengthen weakened heart muscle are experiencing renewed scientific interest after a period of reduced activity in the field. These treatments work by targeting failing hearts at the genetic level to restore cardiac function and improve the heart's pumping ability. The field is attempting to overcome previous setbacks and controversies that had slowed progress in this therapeutic area.
Why it matters
Heart failure affects millions of people worldwide and current treatments often only manage symptoms rather than reverse the underlying muscle weakness. Successful gene therapies could offer a transformative approach to actually restore heart function rather than merely slowing decline.

Treatments aim to bulk up failing hearts to restore their vigour – but can the field move on from past controversy?
