Samuel C Dudley, chief of cardiology at the Cardiovascular Institute (CVI), said that this test will enable physicians to assess a patient's need for an implantable cardiac defibrillator (ICD).

This has led to widespread overuse of ICDs throughout US and abroad, Dudley added.

Dudley further said that they can also refine the need for such a device in most severe cases of sudden cardiac death risk.

The new blood test is in a pilot phase and will be validated in a large, multi-site trial.

The trial led by Dudley and other researchers at Lifespan's CVI anticipated to start this fall.

The study was published in the Journal of American College of Cardiology.
