Jerry Lewis - Cause of death revealed by Nevada coroner.
Legendary comedian Jerry Lewis' death Sunday was caused by a heart condition, the Clark County Nevada Coroner determined.
His cause of death is officially listed as ischemic cardiomyopathy, which occurs when the heart becomes unable to pump sufficient blood through the rest of the body due to a coronary artery disease.
An autopsy will not be conducted for Lewis, 91, who had a history of heart issues during his life. Lewis first suffered a heart attack in 1960 when he was 34 years old, and suffered at least two more in 1982 and 2006.
He also battled prostate cancer, Type 1 diabetes, pulmonary fibrosis and viral meningitis in his lifetime, and suffered a major back injury during a fall at a Las Vegas performance in 1965 that almost paralyzed him.
Lewis was surrounded by his family at his Las Vegas home when he died on Sunday. His family issued a statement shortly after his death saying he had "passed away peacefully" of "natural causes."
The comedian's death was mourned by fans and members of the entertainment industry, including actor Robert De Niro, who memorialized Lewis as "a pioneer in comedy and film."
"And he was a friend. I was fortunate to have seen him a few times over the past couple of years," De Niro wrote in a statement. "Even at 91, he didn't miss a beat... Or a punchline. You'll be missed."
