SMR, an acronym for Extracorporeal Shockwave Myocardial Revascularization, is alternatively known as Non-Invasive Cardiac Angiogenesis Therapy (Ni-CATh). This innovative method employs Extracorporeal Shockwave technology to enhance blood supply to the heart muscles, constituting a novel approach to Myocardial Revascularization. ESMR serves as a non-invasive treatment option for ischemic myocardial regions that are challenging to reach through conventional revascularization methods such as Bypass surgery, Balloon Angioplasty, and stenting. This therapy aims to address symptoms arising from myocardial ischemia, offering an alternative for cases where traditional interventions may not be feasible or effective.
