In mice, blocking heart-to-brain signals improved healing after a heart attack, hinting at new targets for cardiac therapy.

Researchers discovered a feedback loop between nerve cells, the immune system and the heart. They think it shows promise as a target for future therapies.

University of California San Diego research, led by the School of Biological Sciences, looks at new ways heart attacks can be treated.

Arteries become clogged. Blood flow is restricted and oxygen is cut off. The result is a heart attack, the world's leading cause of death.

"I realised this is a heart attack and it could mean the end of my life. "I thought 'oh my god, I could die'. "I realised that this could be my last moment." Fortunately, at the time of her heart attack, she was on the phone to a friend, who called for an ambulance that took her to hospital.

A newly discovered collection of neurons suggests the brain and heart communicate to trigger a neuroimmune response after a heart attack, which may pave the way for new therapies

It is a miracle that Phil Vassar is still alive. At least that is what the 63-year-old country star said his doctors told him. Vassar revealed as much in an interview with Forbes last year in which he revealed that he had a heart attack that was followed by a stroke in short order.
