EECP Therapy for Heart Failure: A Revolutionary Non-Invasive Treatment Option
EECP Therapy for Heart Failure: Heart failure affects millions worldwide, causing significant suffering and economic burden. Among the various treatment options available today, Enhanced External Counterpulsation (EECP) therapy for heart failure has emerged as a promising non-invasive approach, particularly for patients with ischemic heart failure. This blog explores the science behind EECP therapy for heart failure, its effectiveness, ideal candidates, and what patients can expect from this treatment.
Understanding Heart Failure
Heart failure occurs when the heart cannot pump enough blood to meet the body’s needs. Despite its name, heart failure doesn’t mean the heart has stopped working—rather, it means the heart isn’t working as efficiently as it should. This serious condition affects approximately 6.2 million adults in the United States alone.
Types of Heart Failure
Heart failure can be categorized based on which side of the heart is affected:
Left-sided heart failure: The most common type, occurs when the left ventricle cannot pump blood effectively
Right-sided heart failure: Often results from left-sided failure, occurs when the right ventricle cannot effectively pump blood to the lungs
Biventricular heart failure: Affects both sides of the heart
Heart failure can also be classified based on ejection fraction (EF)—the percentage of blood pumped out with each contraction:
Heart failure with reduced ejection fraction (HFrEF): EF less than 40%
Heart failure with preserved ejection fraction (HFpEF): EF greater than or equal to 50%
Heart failure with mid-range ejection fraction: EF between 40-49%
Causes of Heart Failure
The primary causes of heart failure include:
- Coronary artery disease (CAD): According to research, CAD is responsible for approximately 48.3% of heart failure cases in China and remains a leading cause worldwide
- Hypertension
- Valvular heart disease
- Cardiomyopathy
- Congenital heart defects
- Arrhythmias
- Diabetes
- Alcohol or drug abuse
Symptoms of Heart Failure
Common symptoms include:
- Shortness of breath during activity or when lying down
- Fatigue and weakness
- Swelling in the legs, ankles, and feet
- Rapid or irregular heartbeat
- Reduced ability to exercise
- Persistent cough or wheezing
- Increased need to urinate, especially at night
- Sudden weight gain from fluid retention
Conventional Treatments for Heart Failure
Before diving into EECP therapy for heart failure, let’s review the conventional treatment approaches:
Medications
Standard medications for heart failure include:
- ACE inhibitors or ARBs to widen blood vessels
- Beta-blockers to slow heart rate and reduce blood pressure
- Diuretics to reduce fluid buildup
- Aldosterone antagonists to help the body eliminate salt and water
- SGLT2 inhibitors, which have shown remarkable benefits in recent years
- Angiotensin receptor-neprilysin inhibitors (ARNIs)
- Digoxin to strengthen heart contractions
- Anticoagulants to prevent blood clots
Devices and Surgical Interventions
When medications aren’t enough, doctors may recommend:
- Implantable cardioverter-defibrillators (ICDs)
- Cardiac resynchronization therapy (CRT)
- Left ventricular assist devices (LVADs)
- Heart valve repair or replacement
- Coronary bypass surgery
- Heart transplantation
Despite these options, many patients continue to experience symptoms or may not be eligible for invasive procedures. This is where EECP therapy for heart failure comes into the picture.
What is EECP Therapy for Heart Failure?
Enhanced External Counterpulsation (EECP) is a non-invasive treatment that uses carefully timed compression of the lower extremities to increase blood flow to the heart. The therapy involves wrapping pressure cuffs around the patient’s calves, thighs, and buttocks. These cuffs inflate and deflate in sync with the patient’s heartbeat:
- During diastole (when the heart is relaxing): The cuffs inflate sequentially from the calves upward
- During systole (when the heart is contracting): The cuffs rapidly deflate
This sequential compression creates a “counterpulsation” effect that:
- Increases blood flow to the coronary arteries during diastole
- Decreases cardiac afterload during systole
- Enhances venous return to the heart
A standard course of EECP therapy for heart failure typically consists of 35 one-hour sessions, usually administered 5 days a week for 7 weeks.
The Potential Mechanisms by Which EECP Improves Heart Function:
At this stage, the effects of EECP are primarily categorized into immediate hemodynamic changes and long-term anti-ischemic benefits driven by shear stress, though other potential mechanisms remain to be explored.

EECP Therapy for Heart Failure: The Science of Working
The research paper provides valuable insights into the mechanisms by which EECP therapy improves heart failure:
Immediate Hemodynamic Effects
- Increased coronary perfusion: EECP therapy increases diastolic blood pressure by 26-157%, significantly improving blood flow to the heart muscle
- Reduced cardiac afterload: Synchronous release of all cuffs during systole can reduce systolic blood pressure by 9-16 mmHg
- Decreased left ventricular energy consumption: Studies using pulse wave analysis technology found reduced myocardial oxygen demand after EECP treatment
Long-term Effects Mediated by Shear Stress
EECP therapy for heart failure creates beneficial shear stress on blood vessel walls, which leads to:
Improved endothelial function:
- Increased production of nitric oxide (NO) and other vasodilators
- Decreased production of endothelin-1 (ET-1) and other vasoconstrictors
- Enhanced endothelial cell-dependent vasodilation
Angiogenesis (formation of new blood vessels):
- Upregulation of vascular endothelial growth factor (VEGF)
- Increased angiopoietin production
- Enhanced proliferation and differentiation of endothelial progenitor cells
Anti-inflammatory and anti-atherosclerotic effects:
- Regulation of inflammatory factors
- Reduction in oxidative stress
- Stabilization of atherosclerotic plaques
Potential direct effects on cardiac contractility:
- Increased plasma adrenomedullin (ADM) levels
- Possible improvements in mitochondrial function
- Potential effects on calcium ion currents in ventricular myocytes
These mechanisms collectively contribute to improved myocardial perfusion, reduced cardiac workload, and enhanced heart function.
Clinical Evidence for EECP Therapy in Heart Failure
Multiple studies have demonstrated the benefits of EECP therapy for heart failure patients:
The PEECH Study
This randomized controlled trial included 130 patients with ischemic heart failure (NYHA class II-III) and found:
- Significant improvements in NYHA classification
- Enhanced quality of life
- Increased total exercise time
- Higher peak oxygen uptake (VO₂peak) one week after treatment
Effects on Performance Status
Studies consistently show that EECP therapy for heart failure improves:
- Exercise capacity (total exercise time)
- 6-minute walk test performance
- NYHA functional classification
Effects on Cardiac Function
Systolic Function
Results on left ventricular ejection fraction (LVEF) are mixed:
- Some studies show no significant improvement
- Others demonstrate marked improvement, especially in patients with baseline LVEF <40%
- Global longitudinal strain (GLS) measurements show promising improvements
Diastolic Function
Studies consistently show improvements in diastolic function markers:
- Enhanced E/A ratio (0.92 ± 0.41 vs. 1.08 ± 0.46, P<0.05)
- Improved E/Ea ratio (12.61 ± 4.22 vs. 15.44 ± 6.96, P<0.05)
- Better peak filling rate (PFR)
The E/A ratio is a measurement used to assess cardiac diastolic function (how well the heart fills with blood between contractions), which I mentioned in the “Effects on Cardiac Function” section of the blog post.
The E/A ratio is an echocardiographic measurement derived from Doppler imaging that evaluates how blood flows through the mitral valve between the left atrium and left ventricle during diastole (the filling phase of the cardiac cycle). It consists of two components:
- E wave (Early diastolic filling): Represents passive filling of the ventricle when the mitral valve first opens. This is the first and usually larger peak on the Doppler waveform.
- A wave (Atrial contraction): Represents the additional blood flow into the ventricle caused by atrial contraction (the “atrial kick”). This is the second peak on the Doppler waveform.
The E/A ratio is calculated by dividing the peak E wave velocity by the peak A wave velocity.
From the Research it has been found that, patients who received EECP therapy showed an improvement in their E/A ratio from 0.92 ± 0.41 to 1.08 ± 0.46 (P < 0.05), indicating enhanced diastolic function after treatment.
A normal E/A ratio typically ranges from about 0.8 to 2.0, depending on age. In heart failure with diastolic dysfunction, this ratio is often abnormal:
- In early/mild diastolic dysfunction: The ratio may be reduced (<0.8)
- In moderate diastolic dysfunction: The ratio may appear pseudonormal (normal-looking but with other abnormal parameters)
- In severe diastolic dysfunction: The ratio may be elevated (>2.0), known as a “restrictive filling pattern”
The improvement in E/A ratio after EECP therapy suggests that this treatment helps the heart fill more efficiently during diastole, which is particularly important for heart failure patients.
Effects on Prognosis
EECP therapy for heart failure appears to improve short-term outcomes:
- Reduced 90-day readmission rates (6.1% vs. predicted 34%)
- 78% reduction in emergency room visits over 6 months
- 73% reduction in hospitalizations over 6 months
