Effects on blood pressure in patients with refractory angina pectoris after enhanced external counterpulsation

Abstract

EECP treatment affects the blood pressure in patients with refractory angina pectoris. The decreased blood pressure may be a result of an improved exercise capacity, an improved endothelial function and vasoreactivity in general.

Expert consensus on the clinical application of enhanced external counterpulsation in elderly people (2019)

“…(1) Arterial pressure: flow pulsatility is unique to EECP hemodynamics, in which diastolic aortic pressure is increased by 26%-157%. 13 Its effects on systolic aortic pressure vary in different studies, which report a lowering of systolic pressure by 9-16 mm Hg (1 mm Hg = 0.133 kPa). (2) Ventricular function: EECP increases cardiac output by an average of 25%.…”

Effect of external counterpulsation on cardiac work following cardiac surgery: Implications of the mechanism responsible for clinical benefits

“…Consequently, ECP improves arterial stiffness [21] and peripheral artery flow-mediated dilatation [22]. Moreover, a 35-h course of ECP improves hypertension [23,24]. These data suggest that the daily acute effect of ECP can cause chronic vasodilation and cardiac afterload reduction.…”

Effect of enhanced extracorporeal counterpulsation in patients with non-arteritic anterior ischaemic optic neuropathy

“…However, although in a previous report, EECP may augment cerebral arterial blood flow [7], no evidence was found to support that EECP increased cerebral venous outflow, which requires further investigation. Another possible mechanism is the reduced systemic systolic pressure after EECP [15], which is associated with reduced IOP [16][17][18]. However, further study is also necessary for the correlation, especially long-term correlation, between IOP and blood pressure.…”
