Drinking champagne could reduce risk of sudden cardiac arrest, study suggests

Maintaining a positive mood and eating more fruit may also help lower risk, researchers find

Drinking champagne, eating more fruit, staying slim and maintaining a positive outlook on life could help reduce the risk of a sudden cardiac arrest, the world's first study of its kind suggests.

Millions of people worldwide die every year after experiencing a sudden cardiac arrest (SCA), when the heart stops pumping blood around the body without warning. They are caused by a dangerous abnormal heart rhythm, when the electrical system in the heart is not working properly. Without immediate treatment such as CPR, those affected will die.
