What is EECP?
EECP (Enhanced External Counterpulsation) is a non-invasive therapy designed to improve blood flow to the heart and other organs. It’s often used for patients with chronic stable angina or those who are not candidates for heart surgery. EECP helps stimulate the growth of new blood vessels, improving circulation and oxygen supply to the heart muscle.
How EECP Therapy Works?
During EECP treatment, inflatable leg cuffs inflate and deflate in sync with your heartbeat. This rhythmic pressure pushes blood toward the heart, improving oxygen delivery and overall cardiac function. Over time, the heart naturally forms new pathways for blood flow — a process known as collateral circulation.
Benefits of EECP Treatment
- Improved Circulation and Oxygen Delivery
- Reduction of Angina Symptoms
- Non-Invasive Alternative to Bypass Surgery
- Enhanced Energy and Quality of Life
Who Can Benefit from EECP Therapy?
- Patients with chronic stable angina
- People not suitable for angioplasty or bypass surgery
- Patients with microvascular angina or small-vessel disease
- Individuals with reduced exercise capacity
- Those with poor coronary collateral circulation
What is the process for EECP Therapy?
Each EECP session lasts about one hour. The patient lies on a treatment table while cuffs are wrapped around their legs. These cuffs inflate in sequence, pushing blood toward the heart. The pressure is carefully synchronized using ECG signals. Treatments are typically performed five days a week for seven weeks. After completing the program, many patients report significant symptom relief and better stamina.
The Role of External Counterpulsation
EECP uses the principle of counterpulsation — inflating cuffs during diastole (heart relaxation) and deflating them before systole (heart contraction). This boosts coronary perfusion while decreasing the workload on the heart.
How EECP Improves Blood Flow
By increasing venous return and reducing after load, EECP enhances cardiac output and stimulates angiogenesis, or new vessel formation. This not only improves oxygen delivery but also helps repair damaged heart tissue.
Connection Between EECP and Heart Function
EECP essentially acts as a mechanical assist for the heart, reducing stress while promoting efficiency. Think of it as a “natural bypass” that encourages the body to create new circulation routes without surgery.
Effectiveness of EECP Therapy
Clinical Studies and Evidence
Multiple studies, including the MUST-EECP trial, have shown that EECP can reduce angina episodes and improve exercise capacity. The therapy is also associated with lower hospital readmission rates for heart patients.
Success Rates of EECP Treatment
Clinical success rates hover around 70–80%, with many patients maintaining benefits for up to three years post-treatment.
