Treatment & Rehabilitation - External Counterpulsation

What is External Counterpulsation (ECP)?
ECP is a non-invasive procedure that may reduce symptoms of chronic angina by helping new blood vessels grow around blocked arteries in the heart. The treatment consists of 35 sessions in a row, each lasting one hour. 

How does ECP work?
Counterpulsation happens while the heart is resting. It is during the rest period that the CardiAssist system actually pumps, sending blood back to the heart. Air is pumped into a series of cuffs wrapped around your calves, thighs, and buttocks. The cuffs squeeze your lower extremities in sequence (like a wave), which increases blood flow back toward your heart. The inflation of these cuffs is timed to your heartbeat so the blood arrives at the exact time your heart relaxes.

What can I expect during the procedure?
Most patients describe the treatment as a vigorous massage. They also say that after you get used to it, reading or sleeping during treatment is very easy. Right after finishing treatment, many patients are energized or invigorated, but some feel a little tired.

How long before I feel better?
Every person is different, but most people start to see an improvement about half way through the treatment. Some feel better after just one week, and some require more than 35 sessions.

Are there any negative aspects of the therapy?
Generally speaking, most patients only require 35 sessions; others may require more. In order to ensure consistent treatment, it is very important that the patient not miss any sessions. The 35 sessions occur over a seven-week period.

Does ECP carry any risks?
Although rare, some people develop minor skin abrasions from the rubbing of the cuff system. Your ECP therapist or your doctor can describe any potential risks or complications that may occur.

What are the advantages of ECP treatment?
ECP is less expensive, non-invasive and doesn’t require healing time after treatment. It is an outpatient procedure that doesn’t require a hospital stay. You can even drive yourself home after each session.

How do I know if I qualify for ECP?
Only your doctor can evaluate your condition and decide if you are a candidate for ECP, but the general criteria are:

• You have symptoms of angina
• You have had previous invasive procedures, such as angioplasty, cardiac stents or bypass surgery, but the pain remains or has returned.
• Nitroglycerin no longer gives you relief from your angina.
• Your physician has said that you are no longer a candidate for any invasive procedure.
