Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older diagnosed with stable angina pectoris who are indicated for CABG and currently on the waiting list.

Probably not a fit

Patients with severe heart conditions such as congestive heart failure or those requiring urgent CABG will not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of External Counterpulsation (ECP) therapy in patients with stable angina pectoris who are on a waiting list for coronary artery bypass grafting (CABG). The study aims to determine if adding ECP therapy to optimal medical treatment can relieve symptoms and improve quality of life during the waiting period. Participants will be randomized into two groups: one receiving ECP therapy and the other receiving standard medical therapy alone. The efficacy will be assessed through echocardiographic measurements, treadmill tests, and clinical outcomes before and after the intervention.

Why it matters

Potential benefit: If successful, this therapy could significantly improve the quality of life and reduce symptoms for patients awaiting CABG.

How similar studies have gone: While the use of ECP therapy has been explored in refractory angina, this specific application for patients awaiting CABG is novel and has not been extensively tested.
