Summary

Low intensity shockwaves have been proven in animal studies to induce local growth of new blood vessels from existing ones. The hypothesis of this study is that shockwave therapy could improve the symptoms of patients with refractory angina not amenable to revascularization with angioplasty or bypass surgery.

Detailed description

Low intensity shockwaves (1/10 the ones used in Lithotripsy) are delivered to myocardial ischemic tissue. Shockwaves are created by a special generator and are focused using a shockwave applicator device. The treatment is guided by standard echocardiography equipment. The shockwaves are delivered in synchronization with Patient R-wave to avoid arrhythmias. The treatment is painless. At first, the patient undergoes stress-SPECT testing to identify the ischemic areas. Following that, the same area is localized by the ultra-sound device and the shockwaves are focused to the ischemic area. Several treatment session (9 in total, spread over 9 weeks) are required for optimal results.
