Tweeting from a hospital bed late last night Californian time, Smith sent out a picture of himself decked out in a hospital gown, covered in wires and tubing. Known for directing his 2010 hit Cop Out and the owner of 'Jay and Bob's Secret Secret Stash', a comic book store which was inspired from his role as Silent Bob from 1994's Clerks, Smith had preformed a stand-up comedy routine earlier that night and was due to perform a second one later that evening.

"I had a massive heart attack. The doctor who saved my life told me I had a 100% blockage of my LAD artery (aka "the Widow-Maker)."

For some further context, the 'LAD' artery (the left anterior descending artery) is a branch of the left coronary artery, which supplies a large quantity of of blood to the left atrium. In short, it means a heart attack stemming from a blockage here is a serious medical issue, that can be fatal if not caught and treated in time.

After the first show this evening, I had a massive heart attack. The Doctor who saved my life told me I had 100% blockage of my LAD artery (aka “the Widow-Maker”). If I hadn’t canceled show 2 to go to the hospital, I would’ve died tonight. But for now, I’m still above ground! pic.twitter.com/M5gSnW9E5h
