Written by When a patient is experiencing heart failure, a leading cause of death worldwide, they begin to lose healthy and functioning cardiac cells. Heart failure causes these once-flexible cells to develop into fibrotic cells that are no longer able to contract and relax. This stiffening of the cardiac cells compromises their ability to carry blood efficiently to the rest of the organs in the human system. Because humans cannot regenerate these cardiac cells, the patient faces a long road to recovery marked by preventative or symptomatic treatments.
