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 ...

Australian researchers have uncovered a crucial new mechanism that helps explain how the heart's major blood vessels form during early development, and how disruptions to this process can lead to ...

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 ...

Human heart development is largely influenced by neural crest cells, which carefully regulate a key growth signal.

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 ...

The most defensible conclusion is not that wild blueberries are a cure or a supplement replacement, but that they are a nutrient-dense food with plausible, evidence-supported benefits for vascular ...

"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 ...
