The results, published in the New England Journal of Medicine, have revealed a number of questions about how to prevent heart attacks. Is exercise and a low-fat diet enough, or should large swathes of the population be prescribed preventative medication? Nature News gets to the heart of the matter.

PACEMAKERS are supposed to protect people from heart attacks. But to do that they have to provide digital as well as biological security.
Earlier this year, a team led by William Maisel at Harvard Medical School demonstrated how a commercial radio transmitter could be used to modify wireless communications from a pacemaker (New Scientist, 22 March, p 23). Doctors normally use these signals to monitor and adjust the implanted device, but a malicious hacker could reprogram the pacemaker to give its wearer damaging shocks, or run down its batteries

Scientists say they have coaxed human embryonic stem cells into becoming three of the major cell types in the human heart, and they improved cardiac function when transplanted into mice. The findings, published in the journal Nature on Wednesday, showed that scientists can efficiently make different kinds of human heart cells for use in basic and clinical research. The researchers said that in the short term, they could be used to test how heart cells respond to different drugs

Approximately 3000 patients in the United States are on the waiting list for a heart transplant, but only about 2000 donor organs become available each year.
This article put forward a new method to solve the life-and-death problem.It includes two pivotal factors:The first one is that we need to find an appropriate stem cell that can give rise to heart tissue;The second one is that the cells require a framework, or scaffolding, to grow on.
Do you think it is feasible to resolve the difficult medical problem?
