The healing power of Enhanced External Counterpulsation (EECP) goes far beyond its physical, mechanical action. The rhythmic pressure is just the beginning. The real, lasting benefits happen on a microscopic, chemical level. EECP initiates a powerful molecular cascade inside the arteries. This cascade involves two critical signalling molecules: Nitric Oxide and VEGF. Together, they unlock the body's own process for building new arteries, known as angiogenesis. The Body’s Core Healing Signals To understand EECP, one must first understand the body's tools for vascular repair. These tools are chemical messengers, each with a very specific job. Nitric Oxide (NO): The Vessel Relaxer Nitric Oxide, or NO, is a simple gas that acts as a potent signalling molecule for blood vessel functioning. Its primary role is to tell the smooth muscles in artery walls to relax. This action, called vasodilation, widens the vessels. Wider vessels lower blood pressure and allow blood to flow fr...
