MANHATTAN — Poison frontman Bret Michaels is back in the hospital after suffering what doctors are calling a “warning stroke,” the rocker's website said.
The new health concern puts into doubt whether Michaels will be able to appear on the May 23rd final episode of "Celebrity Apprentice," and perform at his planned May 28th comeback show.
While investigating the stroke, doctors discovered that Michaels also had a small hole in his heart.
"There is no doubt that the positive Patent Foramen Ovale (PFO) is devastating news to Bret and his family," Michael’s neurosurgeon Dr. Joseph Zabramski said on the rocker’s website. "The good news is that it is operable and treatable."
The incident is the most recent setback after Michaels suffered a brain hemorrhage that left him in critical condition on April 22nd.
“Bret wants everyone to know he cannot thank you enough for all of the well wishes, prayers, and good vibes you have sent his way,” said his spokesperson, Janna Elias.
“Even though these last few months have been tough on him and his family, especially this most recent setback, he is in good spirits, great medical hands and is positive and hopeful that everything is going to be OK.”
