Comment Re:Him, what about healing the original heart (Score 4, Insightful) 38
This technique does have the potential for attaching a mechanical heart that can be used to reduce the strain on the patient's own heart, this can allow the heart to rest and lead to a partial recovery. In about 40% of cases the mechanical heart can later be removed and the patient's own heart can continue to function adequately.
The problem is that when a heart is damaged, scar tissue has to form, but the heart is still functioning, this causes 'remodelling' , where the shape of the heart changes due to weakness in the muscle and extra strain on the functional muscle. This is why following a heart attack, patient's are routinely given beta blockers and ARBs or ACE Inhibitors, to reduce the strain on the heart, in an attempt to reduce this remodelling while the scar tissue is formed. Where there is significant damage, a mechanical heart reduces the load far more than medication can, allowing for better healing.
