Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this study, 2210 cases of ischemic stroke in 72 hours were included in 10 centers in China according to the principle of random, and parallel control. The experimental group receive basic treatment and remote ischemic conditioning for 200mmHg, 2 times per day for 7 consecutive days. The control group receive basic treatment and remote ischemic conditioning control for 60mmHg, 2 times per day for 7 consecutive days. Two groups will be followed up for 90 days to evaluate the efficacy and safety of remote ischemic conditioning in treating acute ischemic stroke.

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.

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: RIC+Standard medical treatment
Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 200 mm Hg. RIC will be conducted twice daily for 7 consecutive days. Additionally, the patients will be treated with standard medical treatment according to the Guidelines for diagnosis and treatment of acute ischemic stroke in China 2014.
