Early data in mice and human tissue indicate that using drugs or gene therapy could allow for cardiac healing in ischemic HF.

Heart attacks and cardiac arrest differ in causes, symptoms, and treatments. Learn how recognizing these emergencies improves ...

Living with a heart that struggles to pump effectively creates daily challenges for millions of Americans. Systolic heart ...

Researchers have significantly expanded the understanding of the genetic causes of atrial fibrillation (AF), a common heart condition that leads to an irregular heartbeat and increases the risk of ...

A premature ventricular contraction occurs when a focus in the ventricle generates an action potential before the next scheduled sinoatrial nodal action potential. Premature, occurring earlier ...

When they stimulated these receptors using aspartame, a common artificial sweetener, they observed an increase in the ...

Check out a few causes of heart attack in kids, including high cholesterol, high blood pressure, chest trauma, and more. Stay ...

A premature atrial contraction (PAC) occurs when a focus in the atrium (not the SA node), generates an action potential before the next scheduled SA node action potential. There are four main ...

These channels act as pathways for electrical currents that help reset the heart's electrical activity after each contraction. For patients with LQTS, this process is prolonged, leading to an ...

the researchers found that it increased the force of heart contractions, as well as improved calcium handling. Both these contribute positively to heart health. The increase in blood pressure and ...

they observed a significant increase in the force of heart muscle contraction and accelerated calcium handling -- key processes for a healthy heartbeat. "After you eat a meal, it's been shown that ...
