Queen's 72-year-old guitarist Brian May said he had had surgery and had been fitted with three stents, BBC reported.
He took to his Instagram to share the news.
By the way, the surgery was carried out early in May, but the musician spoke about this only now.

"I thought I was a very healthy guy," he said.
"But I turned out to have three arteries that were congested and in danger of blocking the supply of blood to my heart."
"I walked out with a heart that's very strong now, so I think I'm in good shape for some time to come."
