Going after the ‘heart attack gremlin’

A protein called Gremlin 2 controls the extent of inflammation after heart attack and may be a good therapeutic target.

Heart repair factor

A signaling factor called Wnt10b is a novel target for optimizing cardiac repair after a heart attack.

Study finds coronary arteries hold heart-regenerating cells

Endothelial cells residing in the coronary arteries can function as cardiac stem cells to produce new heart muscle tissue, Vanderbilt University investigators have discovered.

Novel gene linked to familial atrial fibrillation

A rare genetic variant that occurs more commonly in families of patients with atrial fibrillation (AF) may be a key to better understanding this common and potentially life threatening condition, Vanderbilt University researchers reported this week.

Stem cells take heart

Signaling pathway discoveries suggest ways to induce stem cells to become cardiac muscle cells, which could be useful for regenerating damaged heart muscle.
