Method for estimating pulsatile wall shear stress from one‐dimensional velocity waveforms

Physiological Reports, Volume 11, Issue 7, April 2023., 2023
Abstract Wall shear stress (WSS)—a key regulator of endothelial function—is commonly estimated in vivo using simplified mathematical models based on Poiseuille's flow, assuming a quasi‐steady parabolic velocity distribution, despite evidence that more rapidly time‐varying, pulsatile blood flow during each cardiac cycle modulates flow‐mediated dilation (

Tolerability safety and effectiveness of enhanced external counterpulsation versus individual shear rate therapy in patients with lower extremity atherosclerotic disease: A prospective pilot clinical trial

Acta Physiologica, Volume 237, Issue 3, March 2023., 2023
Abstract Aims We aimed to investigate the tolerability, safety, and effectiveness of enhanced external counterpulsation therapy (EECP) versus individual shear rate therapy (ISRT) in patients with lower extremity atherosclerotic disease (LEAD). Methods Eighteen patients (age: 73.1 ± 6 years) underwent EECP and ISRT, each daily over five consecutive days

Enhanced external counterpulsation for refractory angina pectoris [PDF]

Heart, 2003
Enhanced external counterpulsation (EECP) is a non-invasive outpatient treatment used for angina pectoris. In patients with intractable angina refractory to aggressive surgical and medical treatment, several novel strategies are considered including EECP, transmural laser revascularisation, and spinal cord stimulation.

Chinese expert consensus on the diagnosis and treatment of chronic heart failure in elderly patients (2021)

AGING MEDICINE, Volume 5, Issue 2, Page 78-93, June 2022., 2022
Heart failure results in decreased activity tolerance and repeated hospitalization, seriously affecting quality and mortality of elderly people. Due to the lack of atypical clinical manifestations and characterized symptoms, and accompanied by the coexistence of multiple diseases and geriatric syndromes, comprehensive geriatric assessment should be ...

[Retracted] Cardiac External Counterpulsation Attenuates Myocardial Injury by Regulating NRF2‐mediated Ferroptosisin and Oxidative stress Injury

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Objectives. To explore the role of the external counterpulsation (ECP) myocardial injury by controlling NRF2‐mediated ferroptosis and oxidative stress damage in acute myocardial infarction. Methods. Twenty acute myocardial infarction (AMI) participants hospitalized from January 2021 to January 2022 were enrolled. In addition, 20 healthy individuals who

Enhanced external counterpulsation for chronic angina pectoris [PDF]

Cochrane Database of Systematic Reviews, 2008
Cardiovascular disease is a major cause of death in developed and developing countries. Refractory stable angina pectoris is, in general, inadequately responsive to conventional medical therapy.Enhanced external counterpulsation is a non-invasive treatment for patients with refractory angina and involves the placing of compressible cuffs around the ...

Clinical Status of Cardiac Rehabilitation Manners and Models

Cardiology Research and Practice, Volume 2022, Issue 1, 2022., 2022
Cardiac rehabilitation, which combines cardiology and preventive medicine, is an important part of treatment for cardiovascular diseases. Systematically, cardiac rehabilitation, including simultaneously inhibiting endothelial injury and promoting endothelial repair, is beneficial for physical and mental recovery and reduces the risks of recurrence and ...

Feasibility of a Dielectric Elastomer Augmented Aorta

Advanced Science, Volume 8, Issue 6, March 17, 2021., 2021
A dielectric‐elastomer aorta is used to augment the physiological role of the aorta in the human circulatory system. In vitro experiments show a reduction of 5.5% of the heart energy. The controlled stiffness of the dielectric‐elastomer, which is usually difficult to exploit for actuators, is perfectly matching the assistance principle.

Maximizing the hemodynamic benefit of enhanced external counterpulsation [PDF]

Clinical Cardiology, 1998
AbstractBackground: Enhanced external counterpulsation (EECP) has been demonstrated to be an effective treatment for angina and exertional ischemia in patients with coronary disease.Hypothesis: It is hypothesized that the ability of EECP to enhance the recruitment or development of coronary collaterals in coronary artery disease may be determined by ...
