Maria Callas, 53, Is Dead of Heart Attack in Paris. By RAYMOND ERICSON. Maria Callas, the soprano whose intensely dramatic portrayals made her the most exciting opera singer of her time, died of a heart attack yesterday at her home in Paris. She was 53 years old.
Louella had tried quitting before, so it wasn't because of nicotine withdrawal, not this kind of anger.. Jim had a massive heart attack while Louella was on Chantix, which of course added major stress to their lives. Instead of my wife of 16 years being there for me, it was like my attack was an offense to her, says Jim. It was horrific; she was completely loony.. Louella stopped taking Chantix during Jim's recovery, but for the next five or six months, she also suffered cardiac problems.
