Hugh Hefner ultimately died of cardiac arrest, but

reveals he was also battling a few other ailments.

According to the doc, Hef was suffering from septicemia -- a severe inflammation of body tissues triggered by an infection in the blood. He'd also been dealing with E. coli ... and both are listed as contributing factors.

The main cause of death is listed as cardiac arrest.

As we reported, Hefner died last week at the Playboy Mansion ... surrounded by loved ones at 91.

Tom Petty's wife made a desperate 911 call and told the dispatcher she needed help because her husband wasn't breathing.

Dana York seemed confused and upset when she dialed 911 Sunday night at around 10:45 PM. The dispatcher tried to get her to administer CPR, but Dana needed help. You hear another man take the phone but then Dana takes it back.

She hears very soft breathing, tries CPR and it seems he breathes better.

TMZ broke the story, Tom was in full cardiac arrest and unconscious. He was taken to the hospital and put on life support but there was no brain activity. A chaplain came to administer last rights and he was taken off of life support.

He's not expected to survive the day.

1:35 PM PT -- Sources tell us at 10:30 Monday morning a chaplain was called to Tom's hospital room. We're told the family has a "do not resuscitate" order on Tom. The singer is not expected to live through the day, but he's still clinging to life. A report that the LAPD confirmed the singer's death is inaccurate -- the L.A. County Sheriff's Dept. handled the emergency.

12:30 PM PT -- We're told after Petty got to the hospital he had no brain activity and a decision was made to pull life support.

Tom Petty was rushed to the hospital Sunday night after he was found unconscious, not breathing and in full cardiac arrest ... law enforcement sources tell TMZ.

EMTs rushed to his Malibu home and were able to get a pulse. He was rushed to the UCLA Santa Monica Hospital and our sources say he was put on life support.

Petty's condition is unknown but was critical from the moment he was found.

Petty, who became famous with Tom Petty and the Heartbreakers in 1978 with "Breakdown," is 66.

We've been in touch with numerous people from Petty's camp and they are clearly upset but not talking.

Petty just wrapped a huge tour, ending at the Hollywood Bowl late last Monday.

Story developing ...

The White House became a pink house Sunday to raise awareness for breast cancer ... and Melania Trump's got a great view.

The First Lady tweeted a photo from inside the White House Sunday night, which was illuminated in pink lighting to kick off the start of National Breast Cancer Awareness Month.

The timing is nothing short of uncanny ... Julia Louis-Dreyfus just announced last week that she'd been diagnosed with breast cancer shortly after her sixth Emmys win for "Veep." She didn't reveal what stage she's in ... but she did take the opportunity to call for universal health care.

Jim Carrey has fired back at the mother of his former girlfriend who committed suicide, saying the girlfriend tried to extort him by falsely accusing him of giving her herpes.

Jim is in a battle royale lawsuit over the death of Cathriona White, who killed herself in 2015, shortly after Jim broke up with her.

White's widower and her mom are suing Carrey, claiming he was responsible for her death. They allege in their lawsuit she was distraught over getting herpes, allegedly from Jim.

Carrey says White did indeed text him back in 2013 that she had bumps on her vagina, but he says she actually got those bumps from a wax job. He goes on to say White, with her lawyer, falsely tried to shake Jim down for several million dollars, claiming he gave her an STD.

Jim says the reality ... White had herpes before they even met. As for the wax job, Jim says White and her lawyer used the bumps she got as trumped up evidence of what they said was herpes and tried to pin it on him.

The embattled Health and Human Services Secretary, Tom Price, couldn't weather the firestorm of criticism for his use of private jets -- he's offered his resignation and President Trump accepted.

The news comes just 1 day after Price said "taxpayers won't pay a dime for my seat on those planes." But even that drew ire among his harshest critics because he reportedly totaled over $400k after repeatedly chartering private planes for personal travel. Price said he'd cut a check for only $51,887, the cost of HIS seat.

Trump said earlier Friday he would make a decision "sometime tonight" but Price -- reportedly worth $13 million -- beat him to the punch.

Price didn't seem bothered when we got him in D.C. and used the flu shot to evade our questions.

Hugh Hefner was in failing health for years, and he steadily deteriorated in the final months of his life.

This pic was taken in January ... inside the Playboy Mansion. Although Hef was frail, using a walker to get around, he still hosted movie nights and invited people over.

TMZ broke the story ... Hefner got a back infection 2 years ago and that became the linchpin for a variety of ailments that ultimately led to his death.

Hefner died Wednesday night at age 91.

Hugh Hefner started having serious back issues about 2 years ago, and it was all downhill from there as far as his health ... TMZ has learned.

Sources close to the Playboy founder tell us he already had back problems in his late 80s, but it got much worse when he got an infection. We're told it was so debilitating for Hugh, he could barely walk without assistance and was bedridden soon after.

That's when his public appearances became extremely rare ... one of his last was at the Mansion in May 2016 to announce Playmate of the Year, Eugena Washington.

Fast forward to a couple weeks ago ... our sources say Hef caught a bug, and in his still weakened condition, his immune system simply couldn't fight. We're told it was a mild illness, but family and friends knew it would probably be too much for him.

Hugh was surrounded by loved ones when he died ... including, we're told, his sons Marston and Cooper, his daughter Christie and 2nd wife, Kimberley Conrad.

Health and Human Services Secretary Tom Price was too busy racing to get his flu shot to address the flak over him chartering private flights with taxpayer money.

President Trump says he's not happy and plans to look into claims Price ripped off taxpayers. We got him in D.C. and asked if he was worried about hearing Trump's tagline ... "You're fired."

The HHS Sec. has since apologized, saying he won't take private charters anymore, and will reimburse the expenses for the ones he's already taken. Still, you can tell Price was already feeling the heat, and used the flu to evade questions.

Julia Louis-Dreyfus says she has breast cancer ... and the "Veep" star took a shot at President Trump and Congress while announcing her diagnosis.

Julia just posted, "1 in 8 women get breast cancer. Today, I'm the one."

She added, "The good news is that I have the most glorious group of supportive and caring family and friends, and fantastic insurance through my union." 56-year-old Julia didn't say anything about what stage she's in, or if doctors caught it early.

She did however take a shot at the battle over health care, saying not all women have the benefits she does, "so let's fight all cancers and make universal health care a reality."

Ex-NBA player Bonzi Wells underwent surgery in an Indiana hospital after suffering a heart attack -- but the 41-year-old says he's okay now.

Unclear when Wells was admitted to St. Vincent Hospital in Indianapolis -- but Wells says he's back home now and "feeling good."

Wells told the Star Press the heart attack was "minor" -- explaining, "Small clot hit bottom part of the heart. Had surgery so I'm back to 100% no restrictions."

Wells posted a photo with one of the nurses at the hospital and wrote, "I wanna thank these ladies for saving my life."

"They went above and beyond to make sure I would be ok."

Bonzi played 10 seasons in the NBA for teams including the Sacramento Kings, Memphis Grizzlies and Houston Rockets.

Cardi B isn't the only one benefiting from "Bodak Yellow" hitting No. 1 -- her dentist is also balling out since getting a shout-out in the lyrics.

Dr. Catrise Austin's famous clientele include DJ Khaled, Common, Toni Braxton, Omarosa and Busta Rhymes, but she tells TMZ ... her biz has tripled since 'Bodak' was released.

Those who've been following Cardi since 'Love & Hip-Hop' know she got a serious dental fix-up last year. As she raps ... "Got a bag and fixed my teeth / Hope you hoes know it ain't cheap." It's not just a good rhyme, Dr. Austin says Cardi's porcelain veneers cost as much as a luxury SUV.

Now that the song is on top, Doc's phone's blowing up -- which means Cardi's not the only one making money move.

One of Usher's herpes accusers is firing back at his claim she assumed the risk of catching an STD when she got in bed with him -- and says there was nothing for her to assume.

Laura Helm is the accuser from Georgia who's suing him for $20 million -- and in new docs, obtained by TMZ, she says it's preposterous Usher is calling her out, saying she should've assumed STDs were a possibility when they hooked up.

Helm says that means she would have to have knowledge of the specific danger -- and there was no way for her to have that info because Usher kept his trap shut about it. Bottom line: consent to sex does not equal consent to risk of catching STDs.

Jessica Alba's Honest company is not keeping things mellow with a health and wellness competitor it believes ripped off their brand name to boost sales ... according to a new suit.

Alba's company is going after a Colorado company, Honest Herbal -- which makes cannabinoid rich hemp products -- for trademark infringement. According to the docs ... Herbal intentionally jacked the 'Honest' name to confuse customers into thinking its products are associated with Alba's.

Honest Company claims it sent a letter to Honest Herbal earlier this month asking them to drop the Honest moniker to avoid a suit ... but it was ignored.

Jhene Aiko brought her performance to a screeching halt as soon as she noticed something terribly wrong in the crowd -- one of her fans having a seizure.

The scary incident went down Monday night at Buckhead Theatre in Atlanta where Jhene was headlining. She was in the middle of a song when she stopped the show and frantically called for a medic.

The video shows medics carrying out the fan, who was still violently shaking.

Jhene was classy and poised before resuming the concert, and even warned fans about strobe lights onstage ... which can trigger seizures.

Taylor Swift's latest obsessed fan won't be facing a jury of his peers anytime soon -- the judge says he's mentally unfit to stand trial.

Mohammed Jaffar had a court hearing Monday in New York, where a judge declared he couldn't be tried on the stalking charge against him in his current state, and would remain in custody -- at a mental health facility -- until he is fit for trial.

We broke the story ... Jaffar showed warning signs of his obsession with Taylor as early as 2014 through tweets that became more brazen and troubling over time.

He was busted earlier this year when cops discovered he'd been camping out on the roof of Taylor's building, and buzzed her doorbell for an hour straight.
