Enhanced External Counterpulsation (EECP)
Overview |
Enhanced External Counter-Pulsation (EECP) is a non-invasive medical treatment used primarily for patients with angina pectoris, heart failure, and other cardiovascular conditions. It involves the use of specialized cuffs that are wrapped around the patient's calves, thighs, and buttocks. These cuffs are then inflated and deflated with the patient's cardiac cycle to augment blood flow and improve overall cardiovascular function. |

Mechanism of Action |
EECP works by increasing blood flow to the heart muscle during the resting phase of the cardiac cycle (diastole) and decreasing the workload on the heart during the pumping phase (systole). The treatment involves three sets of cuffs – one each on the calves, thighs, and buttocks. These cuffs are connected to a computer-controlled air compressor. During the treatment, the cuffs inflate sequentially, starting from the calves and moving upwards towards the buttocks - synchronized with the patient's heartbeat. The inflation of the cuffs occurs during diastole, which increases the blood flow to the coronary arteries and improves the supply of oxygenated blood to the heart muscle. As the cuffs deflate just before systole, they reduce the resistance against which the heart has to pump, decreasing the overall workload on the heart. |
Benefits and Clinical Applications | |
|---|---|
Angina Relief | EECP has been particularly effective in relieving angina (chest pain) symptoms in patients with chronic stable angina that is not adequately controlled by medications or other interventions. |
Exercise Tolerance | Patients who undergo EECP treatment often experience improved exercise tolerance and reduced shortness of breath, as the increased blood flow enhances oxygen delivery to the muscles. |
Heart Failure | EECP has been studied as a potential treatment for heart failure. By improving blood flow and reducing the heart's workload, it may help in alleviating symptoms and enhancing overall cardiac function. |
Peripheral Artery Disease | EECP can also be beneficial for patients with peripheral artery disease (PAD), as it promotes blood circulation in the lower limbs. |
Diabetic Neuropathy | Some research suggests that EECP might help improve symptoms of diabetic neuropathy, a complication of diabetes that affects nerve function. |
Treatment Course | A typical EECP treatment course usually consists of daily sessions, lasting about one hour each, for a period of 7 to 9 weeks. During each session, the patient lies on a treatment table, while the cuffs are applied and synchronized with the cardiac cycle. The entire process is non-invasive and painless, and patients can usually read, watch TV, or listen to music during the treatment. |

Considerations |
While EECP is generally considered safe, it might not be suitable for everyone. Individuals with certain conditions, such as uncontrolled hypertension, aortic dissection, severe arrhythmias, recent heart attack, or active deep vein thrombosis, might not be suitable candidates for EECP. It's crucial for patients to be evaluated by a healthcare professional before undergoing the treatment. In summary, Enhanced External Counter-pulsation (EECP) is a non-invasive therapy that utilizes external cuffs to enhance blood flow to the heart and improve cardiac function. It has shown promise in providing relief for angina, improving exercise tolerance, and potentially benefiting heart failure patients and those with peripheral artery disease. However, as with any medical treatment, individual suitability and consultation with a healthcare provider are important considerations. |
