Doctors have confirmed that Bernie Sanders underwent emergency surgery after suffering a heart attack earlier this week.
Bernie Sanders was taken to hospital on Tuesday after complaining of chest pain at a campaign event in Nevada.
The 78-year-old then had emergency surgery, where doctors removed a blockage in one of his arteries.
Sanders left the hospital saying that he felt "great", and that he looked forward to getting back on the campaign trail.
"After presenting to an outside facility with chest pain, Sen. Sanders was diagnosed with a myocardial infarction", said Doctor Arturo Marchand, according to a number of US media outlets.
His wife has since confirmed that he will still be participating in the fourth Democratic debate on 15 October.
Sanders released a statement thanking the doctors after almost three days in the hospital.
It read: "I want to thank the doctors, nurses, and staff at the Desert Springs Hospital Medical Center for the excellent care that they provided. After two and a half days in the hospital, I feel great, and after taking a short time off, I look forward to getting back to work."
He also posted a video alongside his wife on his Twitter page, saying that he was looking forward to getting back on the campaign trail:
Hello everybody! We’re in Las Vegas. I’m feeling so much better.
Thank you for all of the love and warm wishes that you sent me.
See you soon on the campaign trail. pic.twitter.com/nk3wWIAuE7
