Michael Lohan's heart surgery is delayed after doctors find blood clots in one of his lungs

The estranged father of Lindsay Lohan was too ill to undergo an operation on his heart yesterday, after doctors found blood clots in one of his lungs.

He was scheduled to have stents put in his arteries, but that will now have to wait until Monday at the earliest, according to TMZ.

Michael Lohan was rushed to hospital last night after suffering chest pains while staying in a court-ordered treatment facility.

The 51-year-old father of troubled star Lindsay Lohan underwent emergency heart surgery today at the Lee Memorial Hospital in Ft. Myers, Florida.

His close friend Tom Murro tells Radar Online that Lohan had a procedure called an angioplasty in an effort to correct a problem with diminished blood flow to his heart.

Lohan recently entered a rehab program for a 120 day anger management program.

He has a history of heart problems.

The Celebrity Rehab star, who was rushed to the ER with heart issues earlier this year, is expected to return to the centre when his condition stabilizes.

He has admitted in interviews that doctors wanted to put stents in his arteries to allow his blood to flow unhindered, as long as three years ago, but he never had the operation.

Lohan pleaded no contest to domestic violence charges in Florida last week and avoided a jail sentence.

He was told he must not contact his ex-girlfriend, Kate Major, a 29-year-old former Star Magazine reporter who he was accused of battering in October.

Lohan told Judge Nick Nazaretian he wanted nothing to do with Major.
'My hand has been bit too many times,' said Lohan, who was wearing a red Hillsborough County Jail outfit.

The agreement reached between Lohan and Hillsborough County prosecutors means he will spend four months of his one-year probation at a residential program in Fort Myers.

After that, he must complete a domestic violence batterer's intervention programme.

The elder Lohan was arrested in Tampa on October 25. A judge warned him not to make any contact with Major.

But two days later, he was accused of violating the terms of his release by making a harassing phone call to her just hours after being released from jail.

Major told the court that Lohan would benefit from a treatment programme and not jail.

'I think he needs help,' she said. 'Keeping him in jail would be hurting him more.'

Major also talked briefly about Lohan's famous daughter, Lindsay, an actress who also has had her share of brushes with the law.

'It's my birthday today,' said Major. 'A year ago, we were worried about Lindsay,' she said.

Judge Nazaretian replied: 'I'm not sure who that is.'

A few giggles were heard in the courtroom.

Major also said she did not want Lohan's family or friends to contact her or her family.

The judge ordered Lohan to have no contact with Major, otherwise he would be sent to jail for two years.

'No contact is nothing,' said Nazaretian. 'Zero. Minus zero.'

At one point, Lohan made a face when Major was speaking. Nazaretian reprimanded Lohan sharply.

'It's not Disney World, so stop,' said the judge. 'How old are you? Don't act like a child.'
