While recovering from heart surgery, Bret Michaels suffered a massive drop in blood pressure, but his doctor found the cause and the singer is doing better again.
“Bret suffered no setbacks and is fine. It’s always good for patients to be evaluated when they’re not feeling well,” says Dr. Mansour Assar, an interventional cardiologist.
The rocker, 47, is recuperating at home in Arizona after undergoing surgery Jan. 24 to repair a hole in his heart. The hole was discovered when he suffered a mini-stroke last May.
