We. Lawson et al., CAN ANGIOGRAPHIC FINDINGS PREDICT WHICH CORONARY PATIENTS WILL BENEFIT FROM ENHANCED EXTERNAL COUNTERPULSATION, The American journal of cardiology, 77(12), 1996, pp. 1107
Enhanced external counterpulsation is an effective treatment for chron
ic angina. Theoretical considerations predict greatest benefit in pati
ents with al least patent conduit in this group of 50 patients (all of
whom improved clinically). Improvement in radionuclide stress perfusi
on imaging was seen in 80% of treated patients and was inversely relat
ed to extent of coronary disease.
