Maintaining a stable heartbeat is critical for survival. Your heart must constantly adapt its output to meet changing demands for oxygen and nutrients. Traditionally, scientists have attributed this ...

We believe the human heart evolved away from the trabeculated structure seen in the other great apes to enhance its ability to twist and contract more efficiently. This increased twisting motion, ...

New research from Karolinska Institutet and Columbia University shows that the heart has a mini-brain – its own nervous system that controls the heartbeat. A better understanding of this system, which ...

A new study reveals that encapsulated heating methods, an often-used heat simulation method, significantly increase heart rates and cardiac strain compared to natural heat exposure like those ...

Lower cardiac output has been tied to poorer cerebral blood flow (CBF) in the temporal lobes of older adults without heart failure, a finding that adds to a growing body of research linking heart ...

Researchers at the Nora Eccles Harrison Cardiovascular Research and Training Institute, University of Utah, and the University of Utah School of Medicine, have demonstrated that a gene therapy can ...

AN INTERNATIONAL team of scientists have provided new insight into the Frank-Starling mechanism; a fundamental aspect of human heart function. The Frank-Starling mechanism described more than a ...

Atrial fibrillation, or A-fib, is an irregular heart rhythm that increases a person’s risk of stroke, heart failure, and even premature death. While many risk factors contribute to A-fib, one stands ...

"Understanding this system better could lead to new insights into heart diseases and help develop new treatments for diseases such as arrhythmias." The study was conducted on zebrafish, an animal ...
