Diane Ladd’s cause of death appeared on the death certificate

Diane Ladd’s cause of death was revealed a week after the three-time Oscar-nominated “Rambling Rose” and “Wild at Heart” star died at age 89.

The actress “died of acute hypoxic respiratory failure,” according to her death certificate obtained by PEOPLE. The Cleveland Clinic says this condition is the result of insufficient oxygen in a person’s blood and is usually caused by heart and lung conditions.

The death certificate notes in the report that Ladd had the latter. Two years before her death, Ladd was diagnosed with idiopathic pulmonary fibrosis, a disease in which “lung tissue becomes damaged and scarred,” according to the Mayo Clinic. Esophageal instability — disorders that affect the ability of the esophagus to move food and liquids into the human stomach — also contributed to Ladd’s death, the people reported.

Ladd was cremated on November 10, a week after her death, the death certificate said.

Laura Dern, Ladd’s daughter with Oscar-nominated actor Bruce Dern, announced her mother’s death on Nov. 3: “My amazing hero and my mother’s deepest gift, Diane Ladd, passed away this morning at her home in Ojai by her side.”

“She was the greatest daughter, mother, grandmother, actress, artist and compassionate soul that only dreams could make manifest,” Dern, the Oscar-winning star of “Marriage Story,” said in a statement. “We are blessed to have her.”

Bruce Dern, the first of Ladd’s three husbands, praised his ex-wife for her work on and off the screen, including her long tenure as a Screen Actors Guild board member.

“She was a great friend to her co-workers. She was funny, smart, kind,” he said. “But most importantly to me, she was a wonderful mother to our incredibly fierce daughter. And for that I will be forever grateful.”

The Mississippi native Ladd was an enduring talent whose screen career from the 1960s to 2020 included more than 200 film and television credits and numerous Emmy and Oscar nominations. Famously, she appeared in director Martin Scorsese and writer Robert Getchell’s 1974 feature Alice Doesn’t Live Here Anymore, debuting the role of roadside diner waitress Florence Jean “Flo” Castleberry.

When Ladd was diagnosed with idiopathic pulmonary fibrosis in 2023, she was told she might only have six months to live. This prompted Laura Dern to take her mother out for a walk along Santa Monica, leading to an interesting conversation that will be published in April 2023 for their joint book, “Honey, Baby, Mine.”

“All the deep listening filled us with love,” Ladd told People at the book launch. “And it was very therapeutic.”
