The Core Working Principle of EECP: Synchronized Pressure
EECP is built on a principle called "counterpulsation". Inflatable cuffs wrapped around the calves, thighs and buttocks work in sync with your heartbeat through an ECG device. While the heart is resting (diastole), the cuffs inflate in sequence from bottom to top; the moment the heart contracts (systole), the pressure is suddenly released.
This synchronized movement has two main effects: while the heart rests, it pushes blood from the legs upward toward the heart and the coronary vessels; when the heart contracts, the sudden release of pressure lowers vascular resistance and makes it easier for the heart to pump. As a result, the heart works less while the amount of blood reaching the coronary circulation increases.
What Happens in the Body During a Session?
A standard EECP session lasts about one hour and is performed lying down, fully clothed. A sensor placed on your finger and ECG electrodes placed on your chest allow the device to adjust the cuff timing to your heart rhythm; while the heart rests, the cuffs inflate in a wave from the calf toward the buttocks, and the moment the heart beats the pressure is suddenly released. This cycle is repeated on average 60-80 times per minute throughout the session.
What Changes in the Long Term? Collateral Vessels and Effects Within the Vessels
The effect of a single EECP session is temporary; however, when the treatment protocol (usually 35 sessions) is repeated, the scientific literature describes several physiological changes: collateral vessel development — it is thought that repeated increases in flow may encourage the body to develop its own "natural bypass" routes around blocked or narrowed vessels; endothelial function — the shear stress that blood flow creates on the vessel wall has been associated with increased nitric oxide release by the endothelial cells lining the vessel; arterial stiffness — in some randomized studies, a reduction in arterial stiffness has been observed in patients receiving active EECP.
These effects can vary from person to person and may not be observed at the same level in every patient; whether EECP is suitable for you can only be determined by an individual cardiological assessment.
Scientific Studies Supporting This Mechanism
The mechanism and effectiveness of EECP have been the subject of scientific research for more than 30 years, including the MUST-EECP randomized controlled trial, the multicenter IEPR patient registry, and randomized studies on arterial stiffness.
