LOS ANGELES (Reuters) - Rock singer Bret Michaels suffered a mini-stroke this week and tests showed he has a hole in his heart, the Poison frontman's official website said on Thursday.
Michaels, who survived a potentially fatal brain hemorrhage in April, was readmitted to the hospital after experiencing numbness on the left side of his body.
Doctors said he had suffered a transient ischemic attack, known as a warning or mini-stroke, and they later found he had a hole in his heart. They said it was "highly unlikely that the problems were related to the brain hemorrhage," according to a statement on website BretMichaels.com.
They said the heart condition was operable, but that for now he would receive blood thinners and outpatient treatment.
It was not immediately clear when the singer and "Celebrity Apprentice" TV contestant fell ill.
He gave a TV interview to the "Oprah Winfrey Show" that was broadcast on Wednesday. The interview was taped a week ago, his publicist said.
Michaels' neurosurgeon, Dr. Joseph Zabramski, said the singer, who plans to play a comeback music gig on May 28, was determined to make a quick recovery.
"Medically speaking it is a fantastic attitude both mentally and physically for him to have," Zabramski said. "However, Bret's brain and body are not quite 100 percent yet, especially with the hole found in his heart."
Michaels told Winfrey he was still getting headaches but felt lucky to be alive. The glam rock singer also suffers from diabetes and underwent an emergency appendectomy two weeks before suffering a brain hemorrhage on April 25.
He had said he hopes to take part in the May 23 live finale of "The Celebrity Apprentice", where he is in the running to win the competition. Most of the NBC TV show was shot before Michaels' string of medical emergencies.
Michaels' manager Janna Elias described the singer as "up, walking, talking, continuing his daily rehab and very happy to be alive. But he has made it clear he is sick and tired of being in the hospital and is ready to rock again."
