Pneumatic external counterpulsation: a new noninvasive method to improve organ perfusion.

Pneumatic external counterpulsation, which is operated by applying electrocardiographic-triggered diastolic pressure via air-filled cuffs to the vascular limbs of lower limbs, is a relatively new therapeutic option for patients with angina pectoris and cerebrovascular diseases like transient ischemic attacks or sudden deafness. In this study, an augmentation in flow volume in the carotid, renal, and hepatic arteries from 20% to 25% and in the coronary arteries from 20% to 40%, as well as an increase in stroke volume by 12% was demonstrated; this shows the therapeutic results in patients with diseases caused by disturbed organ perfusion.
