What Do Follow-Up Data Show?
Long-term follow-up data from multicenter registries such as the International EECP Patient Registry (IEPR) show that the symptomatic benefit observed after treatment persists in some patients for months or even years. However, since this type of registry data does not include randomized controlled comparisons, the results should be interpreted with caution, and it should be kept in mind that outcomes can vary from person to person.
Factors Affecting Durability
According to mechanisms discussed in the literature, the sustainability of EECP's effect is associated with factors such as: the persistence of collateral blood vessels (the body's own natural bypass pathways) that develop during treatment; healthy lifestyle habits maintained after treatment (diet, exercise, not smoking); the rate of progression of the underlying cardiovascular disease; and continuing medication and regular cardiological follow-up.
For this reason, EECP should be viewed not as a one-time "treatment" but as part of the broader management of cardiovascular health.
Limitations of the Scientific Evidence
Most of the current evidence on long-term effectiveness comes from patient registries; the number of studies comparing long-term outcomes through randomization is limited. Some systematic reviews emphasize the need for higher-quality, longer-term randomized studies.
What to Do After Treatment
Patients who want the best and most lasting results from EECP treatment are generally advised to: continue regular follow-up appointments with their cardiology team; take prescribed medications as directed; adopt heart-healthy eating and regular physical activity habits; and avoid risk factors such as smoking and excessive stress.
