Enhanced external counterpulsation (EECP) is a new treatment for
people who have ongoing chest pain (chronic
angina) who do not qualify for other treatment
methods, such as
angioplasty or surgery. Also, it is sometimes used to
treat
heart failure. In Canada, this treatment is available but is not covered by provincial health plans. It is expensive, and currently it is not often used in Canada to treat heart failure.
During EECP, pressure cuffs (like large blood pressure cuffs) inflate
and deflate around your calves, thighs, and buttocks. The cuffs squeeze the
blood from your lower body toward your heart. In turn, this increases the
amount of blood and oxygen going into your coronary arteries and decreases pain
from angina. Meanwhile, your blood pressure and heart rhythm are closely
monitored. Usually, you will receive this treatment for 1 to 2 hours a day, 5
days a week, for 7 weeks.
Although it has not been proven, EECP may encourage the development of
collateral blood vessels. These small blood vessels can create new channels for
blood to bypass narrowed or blocked arteries.
In one
study, 81% of the people treated for
chronic angina with EECP improved.1 However, EECP has
some drawbacks. Many people are not candidates, and the treatment can be
time-consuming and uncomfortable.
