Evaluating External Counterpulsation ECP Therapy for Adults with Stable Angina Waiting for Coronary Bypass Surgery in Bandung, Indonesia

What this Trial Is About

This research aims to evaluate the effectiveness of adding External Counterpulsation ECP therapy to standard medical treatment for patients with stable angina pectoris who are waiting for coronary artery bypass grafting CABG surgery. The study addresses the longer waiting times for CABG in Indonesia, which may increase risks during this period. The goal is to assess whether ECP can relieve symptoms and improve heart function and quality of life in these patients. Participants will be randomly assigned to either the intervention group receiving ECP therapy or the control group receiving only medical treatment. ECP therapy involves 36 sessions, each lasting one hour, conducted five days a week with an initial pressure of 300mmHg. The control group will not receive this therapy. The study will compare changes in heart function and symptoms between the two groups. Participants will undergo assessments before and after the seven-week intervention period, including echocardiography, treadmill tests, and questionnaires measuring angina severity and quality of life. Additional tests may include nuclear myocardial perfusion imaging and blood tests for heart-related biomarkers. Researchers will monitor major adverse cardiac events over two years and perform safety oversight. The total study duration includes the seven-week intervention and long-term follow-up for safety and effectiveness.
