In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type of heart failure experience weakened heart muscles, and that losing weight ...

Working with heart muscle cells from diabetic rats, scientists at Johns Hopkins have located what they say is the epicenter of mischief wreaked by too much blood sugar and used a sugar-gobbling enzyme ...

Contraction of the heart is driven by cyclical interactions between myosin and actin filaments powered by ATP hydrolysis. The modular structure of heart muscle and the organ-level synchrony of the ...

The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where ...

No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of Medicine reveals more information about this vital function and how it’s ...

In a surprising discovery, scientists have found that the heart possesses 'sweet taste' receptors, similar to those on our tongues, and that stimulating these receptors with sweet substances can ...

Now, in a study in zebrafish and human heart muscle cells, researchers show that a tiny deletion in the A-band of titin — the loss of just nine amino acids out of more than 27,000 to 35,000 amino ...

The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs and ...
