A clinical study by researchers at Karolinska Institutet and Karolinska University Hospital in Sweden shows that the hunger hormone ghrelin can increase the heart's pump capacity in patients with ...

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 ...

A new gene therapy can reverse the effects of heart failure and restore heart function in a large animal model. The therapy increases the amount of blood the heart can pump and dramatically improves ...

Mammals, from the mighty blue whale to the tiny shrew, inhabit nearly every corner of our planet. Their remarkable adaptability to different environments has long fascinated scientists, with each ...

The heart requires substantial energy to sustain its contractile function. Cardiomyocytes reach full functional maturity through postnatal development. During this process, key aspects such as fuel ...

A clinical study by researchers at Karolinska Institutet and Karolinska University Hospital in Sweden shows that the hunger hormone ghrelin can increase the heart's pump capacity in patients with ...

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 heart has long been thought to be controlled solely by the autonomic nervous system, which transmits signals from the brain. The heart's neural network, which is embedded in the superficial layers ...

Dr Vinayak Agrawal explains why looking at multiple lipids is necessary to determine the heart health of lean Indians. Here ...

The interventricular septum separates the heart’s two ventricles and plays a vital role in maintaining correct bloodflow. Sometimes a defect can occur or be present from birth. This can increase the ...

The coronary sinus (CS) refers to a collection of veins that join together to form a large blood vessel. This vein is located between the left atrium and the left ventricle of the heart. A collection ...
