Using mice as test subjects, the eight-member team of researchers implanted early differentiated cells into the myocardium, a part of the heart that is often damaged in heart attacks. Mice were injected with stem cells that either contained or did not contain a gene known to produce a protein that promotes blood vessel growth...
Yong Fu Xiao, the senior researcher on the team, said the study has far-reaching consequences for those suffering from myocardial infarction (MI), a heart condition common in heart attack victims characterized by an insufficient presence of blood vessels within the myocardium...
...chest four times, and on mine twice. Cheney has had one multiple-bypass operation; I have had two of them. We have both had angioplasties, with stents. A couple of years ago, I drew ahead of Cheney in the fancy-therapy category by having DNA injected into my myocardium in order to induce the growth of new vessels--angiogenesis, a still experimental but highly promising technique that has, in my case, worked miraculously well...

...well enough to be moved to Walter Reed, where he soon suffered three more. In their twice-daily reports, cardiologists tried to distinguish between "mild heart attacks" and "myocardial infarctions." At best, the distinction is difficult to make. Infarction is the process in which part of the myocardium (heart muscle) is killed by being deprived of blood. Even a mild thrombosis and occlusion nearly always causes some infarction, though it may be an extension of an old scar...
