Effects of enhanced external counterpulsation (EECP) on myocardial perfusion.

چکیده
PURPOSE To evaluate whether enhanced external counterpulsation (EECP) exerts an effect on myocardial perfusion. METHODS Eleven patients with angina were studied before and after 35 sessions of EECP treatment. Myocardial perfusion was quantified with positron emission tomography and intravenous 13N-ammonia at rest and after dipyridamole, by means of a two-compartment mathematical model. CONCLUSION The results suggest that EECP has no effect on myocardial perfusion. However, because of the small number of patients in this study and highly variable clinical responses, additional studies are required to corroborate this finding. The beneficial effects of EECP appear to be mediated by other mechanisms.

BACKGROUND Enhanced external counterpulsation (EECP) reduces angina and extends time to exercise-induced ischemia in patients with symptomatic coronary disease. One- and two-center studies and a retrospective case series reported that EECP improves myocardial perfusion in stable angina pectoris. We sought to critically evaluate and quantify the effect of EECP on myocardial perfusion. METHODS ...
