Using magnetic cameras, researchers at Linköping University, Sweden, have examined blood flow in an artificial heart in real ...

The nuclear stress test can show how blood flows through your heart muscles. This reveals how well the heart pumps blood and areas of your heart muscles that do not get enough blood. Nuclear stress is ...

A heart PET scan is a noninvasive imaging test that uses a small amount of radiation. It helps doctors understand how the heart functions and whether it is healthy. Cardiac or heart PET scans create ...

New technology can detect rapid pressure changes inside your heart. The state-of-the-art technology uses magnetic resonance imaging (MRI) to create detailed images of the heart. Using the new ...

Heart valve diseases affect how blood flows through the heart muscle. Not all people experience symptoms, even if the condition is severe. You may recognize these early signs and symptoms of heart ...

An aortic stenosis murmur is an unusual sound the heart makes due to a narrowing of the aortic heart valve. The narrowed heart valve restricts blood flow from the heart, which can create a murmur.

Researchers at the University of East Anglia have used cutting-edge imaging technology to measure acute pressure changes inside the heart. The state-of-the-art technology uses magnetic resonance ...

Second-year students at the University of Texas Medical Branch at Galveston will soon participate in a unique education experience using classroom computers converted into human hearts. Sort of. The ...

A sudden restriction of blood flow to the brain. That's how scientists have traditionally explained why people faint. But several mysteries remain: What causes someone's blood flow to spontaneously ...

From artificial heart valves to cellular transplants, new treatments for cardiovascular ailments are being developed every day. To model how they work, researchers need a reliable way to observe the ...
