A new blood test may be able to tell whether a seemingly strong person is at risk of dying from heart disease , US researchers said.

An older , less sensitive version of the test detects a certain protein in only a small percentage of people ,but a research of the newer test made by Roche found it in about 25% of 3,500 blood samples .And people who had detectable levels of the protein , released by damaged heart muscle , were nearly seven times more likely to die of heart disease within six years.

Both tests look for a protein called cardiac troponin T, which indicates muscle damage in the heart , but the newer test called Elecsys Troponin T is 10 times more sensitive . "This test is among the most powerful predictors of death in the common population we've seen so far ," saidJ amesdeLemosof theUniversity of Texas Southwestern Medical Center in Dallas , whose study appears in the Journal of the American Medical Association .

A year and a half ago, Michael Jones' failing heart left him so weak he couldn't even climb stairs.

But today, after receiving an infusion of his own cardiac stem cells, the 67-year-old handles stairs with ease, works his southeastern Jefferson County land on his tractor, indulges his love of woodworking and is making plans to begin jogging.

"I feel truly well," Jones said. "It's awesome. They're using the body to actually heal itself."

Jones is one of several part patients suffering with heart failure who have benefited from a University of Louisville stem cell study that was the subject of a presentation Monday at an American Heart Association session in Chicago.

Study co-leader Dr. Roberto Bolli from U of L described initial results of ongoing research using cardiac stem cells to heal hearts. His partner in the study is Dr. Piero Anversa of Brigham and Women's Hospital in Boston.

Four months after being given stem cells, Bolli said, nine patients showed an average of 9% improvement in left ventricular function — how well the heart pumps blood to the rest of the body and an indication of how well the heart is working.
