The New Therapeutic Approach with the Enhanced External Counterpulsation in Patients with Chronic Stable Angina: Evaluation of Myocardial Flow and Flow Reserve by N-13 Ammonia Pet. Masuda, D, Circulation 100:18 Suppl. 1 Nov. '99
Our most precise indicator of coronary artery blood flow is the PET (Positron Emission Tomography) Scan. Here the scan measures not only blood flow, but the metabolic function of the heart muscle cells supplied with blood and oxygen by a given coronary artery. Dr.Masuda recorded coronary artery flow reserve by the Dipyridamole PET technique, nitric oxide levels, and treadmill time in 11 patients undergoing a 35 hour course of EECP.

Dr.Masuda recorded coronary artery flow reserve by the Dipyridamole PET technique, nitric oxide levels, and treadmill time in 11 patients undergoing a 35 hour course of EECP.
Treadmill time improved by 49 seconds, or 12%, from 390 to 439 seconds. Time to ST depression, the EKG event reflecting insufficient blood flow to the exercising heart muscle, increased by 185 seconds, essentially doubling, from 190 to 375 seconds. Nitric oxide level doubled, and regional perfusion, the PET indicator of collateral generation, increased in all vascular distributions studied.
With EECP, collateral vessels are recruited and enlarged, nitric oxide and antioxidant levels rise, renin and endothelin levels fall, PET, Thallium, and stress EKG findings improve, angina decreases and patients feel better.
EECP is getting the job done!
