Effect of External Counter Pulsation on Ischemic Stroke

December 12, 2017 updated by: Guifu Wu, Eighth Affiliated Hospital, Sun Yat-sen University

Effect of External Counter Pulsation on IschemicStroke (ECP-STROKE)

Stroke is a prevalent atherosclerosis vascular disease with high mortality, external counter pulsation (ECP) is an approved noninvasive therapy for angina, congestive heart failure, myocardial infarction, and cardiogenic shock that augments blood flow to cardiac and systemic circuits, which improves the flow volume in the carotid. Though ECP is Ⅱa recommendation for stroke management, no multi-center control clinical study has been reported for prognosis of stroke. The aim of this study is to evaluate the effect of ECP on stoke. To address this assumption, investigators enroll subjects with ischemic stroke and randomized into control or ECP group, the ECP intervention will be carried out with a standard protocol which involves 35 one-hour sessions (5 days a week) for continuous 7 weeks. The primary endpoint is mRS score in 3 months, secondary endpoints include NIHSS, BI and MMSE score, recurrence of stroke in 3 months, glycolipid metabolism, transcranial doppler (TCD) flow velocities and endothelial function.

Detailed Description

Cardiovascular disease is the leading cause of mortality worldwide, accounting for 17.5 million deaths per year; 6.7 million of these deaths are related to stroke. Over 80% of strokes are classified as ischemic. External counter pulsation (ECP) is a non-invasive method which consists of three sets of pneumatic cuffs attached to each of the patient's legs at the calf and lower and upper thigh. The inflation of the cuffs is triggered by a computer, and timing of the inflation is based on the R wave of the electrocardiogram. The ECP therapist adjusts the inflation and deflation timing to provide optimal blood movement per a finger plethysmogram waveform reading. This produces a retrograde flow of blood in the aorta resulting in a diastolic augmentation of blood flow and also an increase in venous return, which leads to an improved carotid perfusion pressure. Cumulative evidences demonstrate that ECP can augment peak diastolic and mean middle cerebral artery flow velocities, accelerate rehabilitation after stroke, however, no multi-center study on the effect of ECP on the prognosis of stroke has been reported. Thus, this study is designed to enroll 380 subjects with ischemic stroke after evaluation of glycolipid metabolism, heart function, transcranial doppler (TCD) flow velocities, endothelial function, NIHSS, BI and MMSE score, they will be randomized into ECP intervention or control group. All subjects receive Guideline-driven standard medical treatment, ECP will be carried out with a standard protocol which involves 35 one-hour sessions (5 days a week) for continuous 7 weeks. Up to the end of ECP intervention, mRS of subjects will be follow up to 3 months, meanwhile, items as above will be retested for comparison.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
