A hidden atrial dysfunction may raise stroke risk in people with transthyretin amyloid cardiomyopathy (ATTR-CM); however, a ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

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 ...

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 ...

Dilated cardiomyopathy (DCM), a leading cause of heart failure, is twice as common in Black individuals as in white ...

Scientists have developed the first fully autonomous biohybrid fish from human stem-cell derived cardiac muscle cells. The artificial fish swims by recreating the muscle contractions of a pumping ...

Hypokalemia may lead to an irregular heartbeat, also known as arrhythmia. Some arrhythmias can be life threatening without treatment, but restoring potassium levels may help reverse symptoms alongside ...

An experimental Cytokinetics drug has Phase 3 data showing it improved the ability of the heart to work during exercise. In addition to meeting this main goal of its pivotal test in a rare ...

ROCKVILLE, MD – 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 ...

Irregular heartbeat conditions affect millions of people worldwide, causing hearts to beat too fast, too slow, or with an uneven rhythm. These cardiac rhythm disturbances, medically known as ...
