Bret MichaelsRocker Bret Michaels suffered a minor health scare following heart surgery, according to PEOPLE.

The 'Rock of Love' star's blood pressure dropped dramatically, which is a significant cause of concern, but his doctors have determined the cause, and Michaels is fine.

"Bret suffered no setbacks and is fine," said Dr. Mansour Assar, an interventional cardiologist. "It's always good for patients to be evaluated when they're not feeling well."

Michaels underwent surgery last month to fix a hole in his heart. Doctors discovered the hole after the rocker suffered a massive subarachnoid hemorrhage in April 2010 that left him hospitalized in critical condition.
