At one time, little could be done for individuals with heart disorders, and for those who had a cardiac arrest. Today, improved medicine and new techniques of treatment allow many cardiac (heart) clients to live almost typical or normal lives. Brand-new kinds of devices and new techniques of performing heart operations have actually conserved the lives of numerous people for whom there was previously no hope.
The arteries of older people might become hardened or narrowed. This may be serious if it takes place in the coronary arteries, for,if the blood supply of the heart is reduced.

Most people who have cardiac arrest recuperate. They should rest for several weeks or more, however they can usually then lead typically normal lives.
