A Non-Invasive Alternative to
What other conditions may be treated with EECP?
The most common cause of congestive heart failure (CHF) is coronary artery disease. Each vessel provides a region of the myocardium with bloodflow, so when the circulation is impaired-or clots occur with local cell death-the muscle function deteriorates. Despite centuries of research and "conventional" approaches, medical treatments for CHF are often inadequate. Many patients require a heart transplant and sadly for most the post-operative prognosis is grim.28,29
Because of its potential value in the treatment of congestive heart failure, EECP has recently been the focus of numerous studies, most notably the PEECH study (Prospective Evaluation of EECP in Congestive Heart Failure). According to Dr. Marc Silver, a member of the PEECH committee and author of Success with Heart Failure30 EECP holds remarkable potential.
"It is clear that EECP is a useful adjunctive therapy for patients with coronary artery disease and early evidence suggests that it is safe and effective in patients whether or not they have a degree of heart failure. What is really exciting is whether EECP might turn out to also be a useful adjunctive therapy for heart failure itself; that is what the early results suggest and that is precisely what the PEECH trial is all about. Heart failure is our new national health care epidemic and there is only so much that can be done with medications; increasingly we are turning to other solutions."31,32
In China the EECP machine is used to treat a variety of problems and studies are currently underway to further define the boundaries of its benefits.33 For example, since EECP increases blood flow everywhere, not just to the heart, organ dysfunction present because of reduced blood flow could thus improve during EECP. Chinese physicians use arm cuffs during the procedure, further increasing blood flow to the brain. In this fashion EECP can be used in the treatment of stroke. This ability of EECP to improve blood flow in general may lead to some additional applications of EECP in this country and around the world.6,31
Despite being developed almost 50 years ago, EECP is a resource that has gone overlooked for far too long. The time has come for External Counterpulsation to become a part of the generally available armamentarium for Cardiology and for general prevention and wellness.
To be referred for EECP, talk with your doctor or your cardiologist. However, many otherwise excellent cardiologists are not fully familiar with EECP, and many tend to push their patients toward experimental or invasive procedures or more drugs, so you may need to seek several opinions. If you or your physician are unaware of EECP they can find more information at:
