News from the frontiers of heart research was mixed. Researchers discovered two genes that appear to contribute to early heart attacks, in part by causing blood to clot abnormally. A small emergency-room study found that drugs used to break up clots may help revive cardiac-arrest patients when such methods as CPR and electrical shock have failed. There were murkier findings regarding people with high levels of homocysteine, an amino acid linked to heart disease. Folic acid and B vitamins help bring homocysteine down, but one study cast doubt on whether this actually improves heart health...
...long. Will a cabbie's brakes fail when you're in the crosswalk? Will you have a violent reaction to bad food? And what about the risks you carry with you all your life? The father and grandfather who died of coronaries in their 50s probably passed the same cardiac weakness on to you. The tendency to take chances on the highway that has twice landed you in traffic court could just as easily land you in the morgue...
...cells, for example, derive from a single hematopoietic stem cell in the bone marrow, and now two groups of scientists from Boston report that they have identified a similar mother stem cell from which most heart cells arise. Working with mice, one group at Massachusetts General Hospital isolated a cardiac stem cell that generates the three major cell types of the mammalian heart, while another group at the hospital found a stem cell that gives rise to the contracting and smooth muscle cells found in heart vessel walls...
