An artificial heart usually lasts for 6 months. An artificial heart is a heart pump that the human body needs to replace with an artificial heart during the transition period before a heart transplant, or while waiting for a donor, because its own original heart function is no longer working. There is a difference between an artificial heart and a normal heart. The artificial heart has no pulse rate and is capable of circulating blood for the body, but has no ejection function. There are relatively few complications within 3 months of implantation of the artificial heart into the body. The artificial heart is non-biological into the body, so it requires anticoagulation, antithrombotic, and other complications in succession. After the artificial heart has been implanted for more than 3 months, complications increase in proportion to time, proportionally.
