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.
Four days after the surgery, his blood pressure plunged. Tests showed the problem was not due to the surgery, but to dehydration and exhaustion, possibly as a result of his diabetes.
His rep adds Michaels is eager to return to his work for the American Diabetes Association and is rooting for the Pittsburgh Steelers at Sunday’s big game.
A Pennsylvania native, Michaels says, “Having the Steelers win (in the playoffs) the night before my surgery was a sweet gift.”
