One of the reasons why scientist grow artificial hearts is because the number of people that die from heart problems is increasing every day. In order to help people with these diseases and shortage of life spans, scientist have build artificial hearts which replaces the human heart and works up 90% as the normal heart does. “Cardiovascular disease, which includes heart failure, is the number one cause of death, killing more people worldwide than all cancers combined.” stated Charles Okeke from SynCardia Systems, Arizona based company who commercialize their Total Artificial Heart Device. In fact, the number of heart donors is also decreasing day by day. According to the U.S. Department of Health & Human Services, “about 4,000 people wait for a donor heart transplant on any given day, while the supply of approximately 2,300 donor hearts annually has been flat in the U.S. for over 20 years”. Knowing that heart donors are so low, scientist have created artificial hearts to supply for those who need heart transplants.
