| | "The important finding in the LVAD clinical study, is that we were able to directly examine and observe histological changes in the heart muscle of patients after they received a new heart and their old one was removed," Dib says. | | | Researchers conducted the multi-center trial, overseen by the U.S. Food and Drug Administration, in patients who had suffered heart attacks or heart failure and whose hearts had reduced pumping ability evidenced by left-ventricular ejection fraction (EF) less than 30 percent. | | | EF rates improved, on average, from 22.7 percent to 35.8 percent — a 58 percent increase — after 12 weeks. |

| | The muscle is flaccid or elastic in this condition. | | | Muscles are probably most relaxed when we are asleep. | | | In comparing a long muscle to a short muscle, the time it takes for individual sarcomeres to contract in each is unchanged, however the contraction will occur over a longer distance in the longer muscle. |

| | Consequently, fast-acting skeletal muscles are composed of dominantly glycolytic white fibers while slow-acting muscles such as those that maintain tone are generally red and oxidative. | | | It is important to note that in relaxed muscle, myosin is in its high-energy conformational state. | | | Since the biochemistry of these activities are best understood for skeletal muscle, this discussion focus on skeletal muscle (noting, where appropriate, differences in the other muscle types). |
