Abdominal aortic aneurysm
Actress Lucille Ball died April 26, 1989 from an abdominal aortic aneurysm. At the time of her death, she was in Cedars-Sinai Medical Center recovering from emergency surgery performed just six days earlier because of a dissecting aortic aneurysm near her heart. Ball was at increased risk, as she had been a heavy smoker for decades.
Marc Daniels
He died of congestive heart failure on April 23, 1989 in Santa Monica, California at the age of 77. His death harkened back, coincidentally, to the beginning of his television career: Daniels died just three days before Lucille Ball, who also died at age 77 from a heart-related illness.
