The 47-year-old actor-director took to Instagram shortly after midnight on Feb. 26 to update his fans about his massive heart attack. Smith snapped a selfie from his hospital bed, showing the various tubes and wires monitoring his heath, and revealed, "The Doctor who saved my life told me I had 100% blockage of my LAD artery (aka 'the Widow-Maker')," he wrote. "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!"
