to the scientists that the inhibitor was indeed present in the heart cells. They then were able to use a video camera to actually measure how strong the individual heart cells were beating. "We put the ARKct into the cells, and failing human hearts...

A little electrical boost may help many heart failure patients

to strengthen the heart's contraction. Last year, the U.S. Food and Drug Administration approved devices that deliver a different form of heart failure treatment called "cardiac resychronization therapy," or CRT, for treating a subgroup of patients w...
Simple tests could signal and prevent heart disease in women, says Pittsburgh researcher
