Lisa Marie Presley died at 54 after going into cardiac arrest, according to reports. Here's what causes it and who's at risk.

• Lisa Marie Presley, Elvis Presley's daughter, has died after suffering cardiac arrest, her mom said.
• The 54-year-old was given CPR and taken to West Hills Hospital in Los Angeles, reports said.

Lisa Marie Presley, the daughter of the rock 'n' roll legend Elvis Presley, has died after going into cardiac arrest at the age of 54, according to reports.

"It is with a heavy heart that I must share the devastating news that my beautiful daughter Lisa Marie has left us," her mother, Priscilla Presley, said in a statement Thursday. "She was the most passionate, strong and loving woman I have ever known."

Paramedics rushed to the younger Presley's home in Calabasas, California, after receiving a call that the singer was experiencing cardiac arrest, TMZ reported. She was given CPR, TMZ added, and epinephrine was administered on the scene to help her regain a pulse before she was taken to the hospital.

A Los Angeles County Sheriff's Department spokesperson told The Hollywood Reporter deputies were at a property in Calabasas for an unnamed woman in her 50s who went into cardiac arrest. The fire department got a pulse before she was taken to West Hills Hospital, the spokesperson added.

Cardiac arrest is more common in older people and men

Cardiac arrest is when the heart suddenly stops beating and pumping blood around the body, starving the brain of oxygen and leading the victim to lose consciousness and stop breathing, according to the British Heart Foundation.

Cardiac arrest can be caused by conditions such as a heart attack, congenital heart disease, heart-valve disease, inflammation of the heart (acute myocarditis), and inherited heart conditions like cardiomyopathy. It can also be caused by electrocution, drug overdoses, severe hemorrhages, and hypoxia, the foundation said.

If someone is going into cardiac arrest, they will suddenly collapse, lose consciousness, be unresponsive, and either will be breathing abnormally (such as gasping) or won't be breathing at all, the organization said.

Older people, men, and those with underlying heart conditions are more at risk of cardiac arrest, but anyone can fall victim. Women are more likely than men to be older when they go into cardiac arrest, a 2019 study published in Circulation found.

About one in 10 cases of cardiac arrest is linked to physical exertion, according to the National Heart, Lung, and Blood Institute. More than 356,000 out-of-hospital cardiac arrests occur every year in the US, with nearly 90% of them being fatal, a 2022 American Heart Association report found.
