Sheppard, who portrayed the character Crowley in “Supernatural,” collapsed in his kitchen, his Instagram account said.

According to Sheppard, the type of heart attack he suffered left him with a chance at survival at “virtually nil,” TMZ reported.

“Six massive heart attacks later, and being brought back from dead 4 times I apparently had a 100% blockage in my LAD,” Sheppard wrote in the caption alongside a photo of himself in a hospital bed.

The actor thanked first responders, medical staff and his wife.

“They went above and beyond,” Sheppard replied to the fire department. “Brought me back 3 times and delivered me safe to St. Joseph’s. Beat 100 pc occlusion in the widowmaker.”

According to the Cleveland Clinic, “a widowmaker heart attack happens when you have a blockage in the biggest artery in your heart. That means blood can’t move through your left anterior descending (LAD) artery, which provides 50% of your heart muscle’s blood supply. Immediate treatment is crucial for a chance at survival.”

In addition to “Supernatural,” Sheppard starred in “Battlestar Galactica,” “Firefly,” “Leverage,” “Doctor Who,” “In the Name of the Father,” and in other television and movie roles.
