A study of U.S. veterans in California found seniors with diabetes or heart disease have an increased risk of death during ...

Cells in the heart and brain communicate via electric signals that travel from cell to cell as “excitation waves.” The presence of, say, scars in the heart can slow down a part of the wave, which can ...

When temperatures soar, so do heart attacks. Now, a lab experiment explains just how temperatures climbing into Fahrenheit’s three-digits can cause ischemia and potential heart attacks, all while ...

Certain groups of people may have twice the risk of dying from a heart attack during heat waves and high levels of fine particulate pollution, according to a new study published in Circulation, the ...

Martha Gabriel knows the effects of sweltering heat. For the last five years, Gabriel has been picking sweet potatoes, beans and tomatoes under the blazing South Florida sun. One scorching summer day ...

Vanderbilt University researchers believe a slow electrochemical wave, known as a damped wave, may be one of the reasons that low-voltage defibrillation shocks fail to halt fibrillation in cardiac ...

Heart cells form a dense, well-coupled excitable medium that displays macroscopic propagating waves of activity with characteristic space scales that are orders of magnitude larger than the cells ...

Certain groups of people may have twice the risk of dying from a heart attack during heat waves and high levels of fine particulate pollution, according to a new study published in Circulation, the ...
