Maintaining a stable heartbeat is critical for survival. Your heart must constantly adapt its output to meet changing demands ...

A new lab-grown material has revealed that some of the effects of aging in the heart may be slowed and even reversed. The discovery could open the door to therapies that rejuvenate the heart by ...

The researchers identified several types of neurons in the heart that have different functions, including a small group of neurons with pacemaker properties. The finding challenges the current view on ...

A heart PET scan is a noninvasive imaging test that uses a small amount of radiation. It helps doctors understand how the heart functions and whether it is healthy. Cardiac or heart PET scans create ...

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 ...

Heart failure is the end-stage of many heart diseases, including and most commonly, heart attack (myocardial infarction). Acute myocardial infarction (MI) causes inflammation and scarring (fibrosis) ...

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 ...

The procedure used to treat arrhythmias typically allows for a short recovery time, but precautions are necessary to preserve healthy heart function. Heart ablation creates little scars on heart ...
