A heroic cat in the U.K. saved his owner’s life by pounding his paws on her chest to wake her up after she suffered a heart attack in her sleep.

Socially isolated individuals are about 30 percent more likely to suffer a stroke or heart attack -- death from either.

Conversely, non-users of those heart medications did not see their likelihood of a heart attack rise on hot days.

Those who died from a severe cardiac event were also four times more likely to have experienced a painful flare-up recently.

Heart attacks can be predicted more than five years before they happen through a simple eye test, according to new research.

An app which uses mobile phone vibrations to measure blood clotting could prevent millions of potentially fatal heart attacks.
