But the many studies that are being done on ED shows that the link goes farther than that for our bloodstream is the main factor blamed for the spread of cancer and many other disorders, being able to bring pathogens to and from the afflicted areas as the body normally works. This spreading mechanism is under intensive study to make better predictions on when heart attacks can occur, initial results pl;acing it at 2 to 3 years after ED begins, making ED a good way of diagnosing and predicting heart attacks for the future.
