When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

Researchers have developed a new therapy that can be injected intravenously right after a heart attack to promote healing and prevent heart failure. The therapy both prompts the immune system to ...
