The document provides information about enhanced external counterpulsation (EECP) therapy, a non-invasive treatment for angina and heart failure. EECP therapy involves inflating and deflating pressure cuffs around the legs in synchronization with the heart's rhythm to increase blood flow to the heart and reduce its workload. Most patients complete 35 hours of hourly treatments over 7 weeks and experience significant symptom relief for up to 3 years. EECP therapy is described as safe and effective for reducing angina and improving quality of life for patients who do not benefit from or wish to avoid invasive heart procedures.
