Heart failure: Intervention possibilities from imaging programmed cell loss

A new nuclear medicine technique using annexin A5 imaging may help identify individuals at risk of developing heart failure by detecting programmed cell loss in the heart muscle. This could lead to earlier intervention and improved treatment options, as cell death is a key factor in worsening left ventricular events.
