Chest pains, heart flutters, heart attack-- they are the signposts of heart troubles. In the past, such symptoms might mean a treadmill stress test or a cardiac catheterization to diagnose the ...

The key to early intervention for cardiac problems may lie in determining the heart’s ‘true’ age, new research suggests.

Researchers were able to look at several components of heart structure and function. They then developed a model to help determine the age of participants’ hearts and also did statistical analyses.

Over the years, discrepancies have remained in regard to correlating components of AVN structure to function, as evidenced by studies from microelectrodes, optical mapping, and the ...
