Blood Flow Most Important
Two doctors have created an artificial heart that consists of two turbines that replace damaged myocardium, or heart muscle, to keep blood flowing throughout the body without the rhythmic pumping that produces a pulse. They hope that this design is a major step forward in developing a "perfect artificial heart" to manage terminal heart disease. Three humans and 50 cows were given these hearts. One person was very close to death but within 2 days of receiving the artificial heart, he could sit up and speak normally. Unfortunately, the man died of unrelated complications a little over a month after getting it. While no pulse would be a bad sign for most of us, the heart's job is to keep blood flowing through the body so it can deliver oxygen and nutrients to the tissues.
