He died of heart disease.

[David L.]

'to die of' : use this when referring to the direct cause, such as cancer, or heart attack.

'to die from' : use when referring to an indirect agent.

So - he died from exposure to radiation (and then the radiation produced cancer, which caused the death)
the sheep died from the heat (which led to dehydration and so, death)
