End-Stage Heart Failure Not the End?
Some Failing Hearts Recover After Treatment With Mechanical Heart and Drugs

Nov. 3, 2006 - End-stage heart failure may not mean the end. Some
patients' hearts recover after a bold new treatment with a mechanical heart
device and powerful drugs.
End-stage heart failure means a person's heart has "remodeled" --
that is, it has suffered so much damage that it has changed shape. Such hearts
barely work. More than half of people with end-stage heart failure die within a
year or two.
Currently, people in this condition get in line for a heart transplant.
While waiting for a transplant, some patients get help from a mechanical
device called a left-ventricular assist device, or LVAD. LVAD implants take
oxygen-rich blood out of the left side of the heart and pump it back through
Usually, patients get worse the longer they are on an LVAD. But once in a
while, a patient's heart shows signs of getting a bit better.
Can this process be helped along? Yes, finds a British research team led by
Emma J. Birks, MD, PhD, and Magdi H. Yacoub, MD, of Imperial College, London,
and the Royal Brompton and Harefield National Health Service Trust, U.K.
The researchers carefully selected 15 patients with end-stage heart failure
who could be placed on an LVAD. Then they gave the patients powerful drugs to
reverse the remodeling process that made their hearts worse.
Once this happened, they gave the patients another set of drugs to keep
their hearts from shrinking.
Eleven of the 15 patients recovered enough to have the LVAD devices
One died in the process. Another died of lung
cancermore than two years after the
LVAD removal. A third patient had severe heart failure -- following an episode
of heavy drinking -- 21 months after LVAD removal. He later had a successful
The eight remaining patients recovered and are leading active lives more
than four years after LVAD removal.
"'End-stage' heart failure can be reversed," Yacoub says in a news
release. "The heart has the capacity to regenerate itself."
"This therapy has the potential to ease the pressure on the
[heart-transplant] waiting list," Birks says in the news release. "[It]
also offers patients a better alternative to a donor heart -- their own,
