Comedian Jason Byrne has had to cancel upcoming British tour dates due to a heart condition.

Byrne said he got a pain in his chest while running recently and later discovered he had three artery blockages. He will undergo surgery to have stents put in his heart in October and is hoping to go back on tour the following month.

The stand-up star announced the news in a video posted on social media.

He said: "Sorry for cancelling a lot of the British tour but there's nothing I can do about it. I went for a run recently, I got pains in my chest, right in my heart, I didn't know what was wrong with me. I went to A&E, got loads of test and eventually they found three blockages.

"So around early October, I'm going to have to get a couple of stents thrown in. Before anybody jumps on, no it was not the vaccine. I had heart professors all around me telling me what was wrong with me, so my heart hasn't enlarged, there's no blood clots, it's actually hereditary, that's what's happened to me."

The comedian urged his followers to get their heart checked, saying: "I'm fit and I'm underweight and I don't smoke and I don't barely ever drink, so I plead to anybody out there to just go and get yourself checked because you don't even know that you'll have any clogging up in your arteries."

He added: "I'll be back on tour hopefully at the start of November if all goes well, which it will go well, it's just stents. See youse all soon, sorry, sorry, sorry."
