Lisa Marie Presley, the daughter of the late "King of Rock & Roll," Elvis Presley, and his ex-wife Priscilla Presley, passed away on Thursday at the age of 54, CNN reported.

Presley reportedly died after suffering a cardiac arrest event Thursday morning that resulted in her being rushed to a hospital and placed in an induced coma in a futile effort to save her life.

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

"We ask for privacy as we try to deal with this profound loss. Thank you for the love and prayers. At this time there will be no further comment," the statement added.

Cardiac arrest resulted in induced coma before death

TMZ was the first to report that Lisa Marie Presley had suffered a cardiac arrest that led to her being admitted to a hospital intensive care unit in critical condition and placed on life-support in an induced coma with a temporary pacemaker installed to keep her alive.

Presley had initially been found unresponsive in her bedroom by a housekeeper, shortly after which her ex-husband with whom she lived, Danny Keough, returned from taking her young children to school and performed CPR until paramedics arrived.

The paramedics then took over administering the life-saving procedure and reportedly gave Presley at least one shot of epinephrine to restore her pulse prior to her being transported to the hospital.

The outlet noted that, per its sources with "direct knowledge" of what had occurred, the incident had not been a suicide attempt by Presley, and that she had been complaining earlier that morning of worsening stomach pains.

A tough life of tragedy and love

Yahoo Entertainment reported that Lisa Marie Presley was born in 1968 at Graceland in Memphis, Tennessee as the only child of Elvis and Priscilla Presley. Her parents got divorced just four years later, and her superstar father infamously died when she was just nine.

She grew up as the eventual heir to her father's estate and became a musician and singer/songwriter in her own right as an adult who would go on to release at least three successful albums, including emotional posthumous duets with her late father on some of his songs.

Lisa Marie's life was filled with tragedy, unfortunately, as she endured the early death of her father, was reportedly sexually abused later by her mother's boyfriend, had issues with drug and alcohol abuse, and grieved over the 2020 suicide of her beloved 27-year-old son Benjamin Keough.

There were happy times as well, particularly involving her four children -- a daughter and son named Riley and Benjamin Keough with first husband Danny Keough, plus twin daughters Harper Vivienne Ann and Finley Aaron Love Lockwood with fourth husband Michael Lockwood. Presley was also briefly married to superstar singer Michael Jackson as well as actor Nicholas Cage.

Was seen celebrating her late father just days before her death

Yahoo noted that Lisa Marie had last been seen publicly just two days prior to her death at the Golden Globes Award ceremony to celebrate and support the award-winning actor who had portrayed her late father in the recent "Elvis" movie, and just four days before that had publicly celebrated what would have been her father's 88th birthday at an event at Graceland.

The fact that Presley died due to heart health issues is not surprising, given that both her father and his mother had died at relatively young ages from heart issues, not to mention the likely toll that her years of drug and alcohol abuse took on her own body.
