The researchers' model simulated the heart pumping blood throughout the body. Then it predicted how much the changes in blood flow caused the heart cells to stretch during a heartbeat. Another ...

A study led by a physician-scientist at the University of Arizona College of Medicine–Tucson's Sarver Heart Center identified ...

Now that scientists know the aorta helps the heart pump blood, they can start working on ... Researchers then crafted an artificial aorta model made of flexible latex to match the actual aorta ...

A new gene therapy can reverse the effects of heart failure and restore heart function in a large animal model. The therapy increases the amount of blood the heart can pump and dramatically ...

He worked with a team at the University of Utah to create a mechanical heart. It was later used in patients awaiting an organ ...

A blood pressure reading displays systolic and diastolic pressure. The heart is a pump that supplies all tissues and organs of the body with oxygen-rich blood. The heartbeat is caused by the heart ...

Blood flows continuously through your body's blood vessels. Your heart is the pump that makes it all possible. The heart is under the rib cage, to the left of your breastbone (sternum) and between ...

A new gene therapy can reverse the effects of heart failure and restore heart function in a large animal model. The therapy increases the amount of blood the heart can pump and dramatically improves ...

The treated hearts' efficiency at pumping blood, which is the main measure of the severity of heart failure, increased over time—not to fully healthy levels, but close to that of healthy hearts.
