Shock Wave Therapy to Improve Blood Flow in Early Heart Disease

This trial is testing extracorporeal shock wave therapy (ESWT)—a non-invasive treatment that uses focused sound waves—to help your heart grow new blood vessels when you have early-stage coronary artery disease. Half of the participants will receive this therapy, and the other half will receive standard medical treatment alone. Researchers will use advanced heart imaging (cardiac MRI) to measure whether the shock wave therapy improves blood flow to your heart muscle.

Many smaller studies have shown that shock wave therapy can reduce chest pain and improve heart function in people with coronary artery disease, but no one has carefully tested this using modern, highly accurate heart imaging. This trial aims to prove whether the treatment actually works by measuring blood flow in the heart before and after therapy.
