Larry King: American TV host recovering after undergoing heart surgery

The 85-year-old is expected to be released soon

Larry King is recovering in hospital after undergoing an angioplasty, according to his official Twitter account.

The 85-year-old was reportedly scheduled for an angiogram Thursday when he began to experience angina, a type of chest pain "caused by reduced blood flow to the heart," according to the Mayo Clinic.

After arriving at the hospital early to be examined, doctors performed an angioplasty, according to a statement from Ora TV.

Following the procedure, King is expected to make a "full recovery".

"His doctor successfully performed the angioplasty and inserted stents to reopen the previous bypass from 1987," the network behind Larry King Now said in a statement. "He has been recuperating in the hospital and is scheduled to be released soon.

"His doctors expect him to make a full recovery."

The TV and radio host previously underwent a quintuple bypass surgery in 1987 after suffering a heart attack.

In addition to issues related to his heart health, King previously battled cancer. In 1999, he was diagnosed with prostate cancer, and in 2017, announced he had been diagnosed with stage 1 lung cancer after a routine check-up.

At the time, King had surgery to have the mass removed.

"They went in through my ribs with a tiny camera and snipped it out," he said, according to People magazine. "I only had a little pain and some shortness of breath but once my speech is back full - and that took about a week - I went right back to work."

King also lives with type 2 diabetes, which he has previously said is "controllable".
