UFC Hall of Famer and Mixed Martial Arts Fighters Association spokesperson Randy Couture, 56, suffered a heart attack yesterday, and successfully underwent surgery to remove a clot and insert a stent, a tube inserted into a blood vessel to keep the passageway open.

In a statement to TMZ Sports, The Natural explained that he’s not dead yet.

“Contrary to recent rumors I have not kicked the bucket yet. I am alive and well. Special thanks to the amazing staff at Cedars Sinai Hospital. From the ER to cardiac ICU thanks for taking care of me. I’m one of those people that has crazy thick blood and nominally high bad cholesterol. Unfortunately, those 2 factors combined to create a nice clot occluding my Diagonal artery. The Cath lab at Cedars got right on it, cleared it out and placed a stint in its place. Thanks to all of you out there expressing your concern. Your love and support mean the world to me and my family. Live your lives to the fullest. You never know when you’ll draw that last breath in!”

Couture’s manager and attorney Sam Spira detailed the circumstances during the heart attack.

“During a workout at Randy’s LA training home Unbreakable Performance in West Hollywood, CA, Randy experienced discomfort in what he initially thought was an offset rib or vertebrae,” explained Spira. “He tried working on a roller to relieve the problem, but that was not successful. Incredibly, Randy finished the entire workout while likely having the beginnings of a heart attack. Shortly thereafter, he drove home and attempted to rest. When the radiating chest pain did not cease, he recognized something was wrong.

“He proceeded to walk multiple blocks to a nearby emergency room rather than battle Los Angeles traffic. Upon his arrival, after an EKG, the medical staff informed Randy he had a heart attack, and would require immediate surgery to resolve the issue.

“The surgery was successful. Randy is now out of intensive care, stable, in good spirits, and well on his way to a speedy and full recovery.”
