The death of Eduardo (Eddy) Guerrero was officially labeled as a heart attack due to heart disease caused by a lengthy history of anabolic steroid usage and recent usage of narcotics medication according to the death certificate released by the Hennepin County (Minneapolis) Medical Examiners Office.
The official cause of death was due to arteriosclerotic heart disease, which is a hardening and narrowing of the arteries that supply the heart with blood and oxygen. That, combined with Guerrero's both enlarged and damaged heart, and his suffering from organomegaly (several enlarged internal organs, likely due to usage of Growth Hormone), created an imbalance. The heart and larger organs needed more blood and oxygen than normal to remain functioning, while the narrowing arteries provided less blood and oxygen to the heart and those organs.
The linking of steroids and painkillers directly with Guerrero's death did not receive hardly any media attention, largely due to nature of the current media. The original AP story didn't list the cause of death to anything other than heart disease, and listed it as from natural causes (which is used to mean no foul play was involved). A later update did note what was listed as significant contributing causes, but almost no outlets picked up on the second story.
