Actor Mark Sheppard recovering in Burbank hospital after multiple heart attacks

BURBANK, Calif. (KABC) -- Actor Mark Sheppard says he's lucky to be alive after experiencing a cardiac emergency.

Sheppard, who starred in the series "Supernatural," collapsed in his kitchen.

He posted on Instagram a picture of him lying in a hospital bed at Providence Saint Joseph Medical Center in Burbank.

The 59-year-old says he survived six heart attacks and was brought back from the dead four times after a complete blockage in his artery.

Sheppard says if it wasn't for his wife, the Los Angeles Fire Department, and the hospital, he wouldn't be alive.
