Eddie Guerrero died on November 13, 2005, at the age of 38 due to acute heart failure caused by atherosclerotic cardiovascular disease. This condition was linked to his past use of anabolic steroids and other substances, which contributed to heart disease and organ enlargement. His death was officially ruled as a heart attack resulting from arteriosclerotic heart disease, which involves the hardening and narrowing of the arteries supplying the heart. Guerrero was found unconscious in his hotel room in Minneapolis by his nephew, Chavo Guerrero Jr., and died shortly thereafter
