In such cases as my grandfather, the condition could lead to sudden cardiac arrest and death. I nearly had a cardiac arrest myself when I heard that, but the doctors assured me my grandfather's case had been mild.
He had fainted and been unconscious for a while, but he didn't need surgery, which was a good thing.
However, the condition had no cure, and he would need to make major lifestyle changes to reduce stress if he wanted to avoid a more serious incident in the future. I could only imagine William's response. He was a workaholic if there ever was one.
There was no way he was going to quit work to rest, I knew him too well to understand that fact.
The doctors kept him in the hospital another three days for monitoring. They'd wanted to keep him a week, but he refused. He said it would be bad for public morale, and he needed to get back to work. And when the king wanted something, no one refused him.
