EECP or cardiac rehab: what is the difference?
EECP and cardiac rehab both aim to ease chest pain and help you do more. They work in opposite ways. In EECP, air cuffs passively squeeze blood up toward the heart while you lie still. In cardiac rehab, your leg muscles actively squeeze blood up toward the heart while you walk or jog, under physician supervision.
We do not offer EECP at Cardiac Rehab. This page explains both, so you can talk to your doctor with the facts.
What is EECP?
EECP is short for a long name: enhanced external counter pulsation. You lie still on a padded table. Air cuffs are wrapped around your calves, thighs and hips.
How a course runs
A heart trace (ECG) tells the machine when your heart is resting between beats. At that moment the cuffs fill with air. They passively squeeze blood up toward the heart, while you lie still. Just before the heart pumps again, they let go.
Cleveland Clinic says the usual course is 35 hours: one hour a day, five days a week, for seven weeks.
Who it is for
Heart guidelines keep EECP for one main group. These are people with long-lasting chest pain (angina) that is not fixed by medicines, stents or bypass. They have no other options left. The US guideline (AHA and ACC, 2023) says EECP may be considered for them. That is Class IIb. The European guideline (ESC, 2019) gave the same grade. Its 2024 update lists EECP only after all other treatments have been tried.
Who should not have it
Cleveland Clinic lists people who should not have it. These include people with a leaky aortic valve or blood clots. They also include an irregular heartbeat called atrial fibrillation, and poor blood flow in the legs. It is not for pregnant women. Common side effects are tiredness and aching muscles. Some people get blisters or sore skin from the cuffs.
What is cardiac rehab?
Cardiac rehab is exercise and advice for heart patients, under physician supervision. You walk or jog while your heart trace is watched.
How the programme runs
At Cardiac Rehab, each session is 90 minutes, 3 times a week (Monday, Wednesday, Friday), for 3 to 9 months. After that, you keep a plan for life, so the gains stay.
What the muscles build
When you walk or jog, your leg muscles tighten and relax. Each time, they actively squeeze blood up the veins toward the heart. This is the body’s own muscle pump. With steady training, the muscles change. They grow more tiny blood vessels, called capillaries. They grow more mitochondria, the parts of each cell that make energy. A 2024 review found mitochondria went up by about 23 to 27%, and capillaries by about 10 to 15%.
Side by side: how they compare
EECP on the left, cardiac rehab on the right. On a phone, EECP comes first.
EECP
- How it works
- Air cuffs passively squeeze blood up toward the heart while you lie still.
- What you do
- Lie still on a table. The machine does the work.
- Who it is for
- Chest pain (angina) that has no other treatment left.
- Guideline grade
- Class IIb: “may be considered” (AHA and ACC 2023, ESC 2019).
- How long a course is
- 35 hours: 1 hour a day, 5 days a week, for 7 weeks.
Cardiac rehab
- How it works
- Your leg muscles actively squeeze blood up toward the heart while you walk or jog.
- What you do
- Walk or jog. Under physician supervision, your heart trace is watched.
- Who it is for
- Almost everyone after a heart attack, a stent or bypass, and people with heart failure.
- Guideline grade
- Class I, Level A: the highest grade (AHA, ACC and ESC).
- How long a course is
- 90 minutes, 3 times a week (Monday, Wednesday, Friday), for 3 to 9 months. Then a plan you keep for life.
How long do the results last, and can I get back to work and recreational sport?
EECP
- Chest pain
- In a large registry, 73 in 100 had less chest pain after the course. Most still had less pain 2 years later.
- A second course
- 18 in 100 needed a second course within 2 years.
- Fitness of the whole body
- In the PEECH trial, peak oxygen use (VO2) did not change overall. Walking time improved for some.
- Leg muscles
- In a small study, the muscles changed only a little, and not the way exercise changes them.
- Back to work
- We found no EECP study that measured this.
- Back to recreational sport
- We found no study.
Cardiac rehab
- Chest pain and heart events
- 28% fewer heart attacks and 35% fewer hospital stays (Cochrane review, 2026, 107 trials).
- Keeping it up
- In a 14-year study, people who kept up supervised exercise for over 3 years had a 33% lower risk of death.
- Fitness of the whole body
- Peak oxygen use (VO2) rose 3.4 units more than without exercise (2025 review, 33 trials). In 8,320 people, the gain was still there a year later.
- Leg muscles
- More mitochondria (about 23 to 27%) and more tiny blood vessels (about 10 to 15%), in a 2024 review.
- Back to work
- 66 in 100 went back to work, against 58 in 100 without rehab (2022 review, 16 studies). With outpatient rehab: 72 in 100.
- Back to recreational sport
- Cardiac rehab helps you take up recreational sport after the course.

What happens at Cardiac Rehab
- A doctor checks you first.
- You get an exercise plan made for you.
- You exercise for 90 minutes, 3 times a week, under physician supervision.
- Step by step, the exercise gets harder as you get stronger.
Why it helps with this
At Cardiac Rehab, your own muscles do the work while you walk or jog. The team watches your heart trace, so you can push a little further each week, safely.
A 2026 review of 107 studies looked at people after a heart attack, a stent or bypass. Those who did cardiac rehab had 28% fewer heart attacks. They had 35% fewer hospital stays.
Heart guidelines in the US (AHA and ACC) and in Europe (ESC) give cardiac rehab their highest grade: Class I, Level A.
Cardiac Rehab, Jubilee Hills, Hyderabad runs these sessions.
Frequently asked questions
Is EECP the same as cardiac rehab?
No. In EECP, cuffs passively squeeze blood up while you lie still. In cardiac rehab, your muscles actively squeeze blood up while you walk or jog, under physician supervision. Cardiac rehab also teaches healthy habits and helps with worry.
Who gets EECP?
Heart guidelines use it mainly for long-lasting chest pain that is not fixed by medicines, stents or bypass. It is for people with no other options. Your heart doctor decides if it suits you.
Which has the stronger guideline grade?
Cardiac rehab. AHA, ACC and ESC give it Class I, Level A, their highest grade. EECP has Class IIb, which means it may be considered, and only for hard to treat angina.
Can I do both?
Ask your heart doctor. EECP is a separate treatment that we do not offer. Cardiac rehab can be done alongside your other heart care.
How long do the results last?
For EECP, chest pain relief often lasts. In a large registry, most people still had less pain 2 years later. 18 in 100 needed a second course. For cardiac rehab, fitness gains were still there a year later in a study of 8,320 people. Gains from exercise stay as long as you keep moving.
Will it help me go back to work or recreational sport?
For cardiac rehab, studies say yes for work. In a 2022 review, 66 in 100 went back to work after rehab, against 58 in 100 without it. We found no EECP studies that measured this. Cardiac rehab helps you take up recreational sport after the course.
Does cardiac rehab help angina?
Yes. The European guideline (ESC, 2024) says exercise training leads to fewer hospital stays and fewer heart problems in people with heart disease. It says exercise should be offered to everyone with stable heart disease, which includes stable angina.
This page is general advice. Your own doctor knows your heart. If your doctor has told you something different, follow your doctor.
