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

which are composed of multiple proteins important for heart contraction and relaxation,” says Shaw. Hong argues cBIN1 offers important advantages over previous gene therapy targets. Where ...

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 ...

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 ...

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

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 ...

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 ...

Using the sweetener aspartame on the hearts of both humans and mice, the researchers found that it increased the force of heart contractions, as well as improved calcium handling. Both these ...

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

Istaroxime is a novel treatment that has shown potential in improving the heart’s contraction and relaxation while boosting ...
