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

Current studies have shown that remote ischemic conditioning can activate neuronal signals and humoral factors, increase cerebral perfusion and promote neurological recovery in patients with ischemic stroke.The purpose of this study was to investigate the effect of remote ischemic conditioning on cerebral hemodynamics in patients with acute ischemic stroke.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age ≥18 years, <80 years, both sex;
  2. Patients with a clinically definite diagnosis of acute ischemic stroke who are able to commence RIC treatment within 72 hours of stroke onset;
  3. Baseline National Institute of Health Stroke Scale (NIHSS) score<25;
  4. Pre-onset modified Rankin Scale (mRS) score ≤ 1;
  5. Glasgow Coma Scale score ≥8;
  6. Signed and dated informed consent is obtained.

Exclusion Criteria:

  1. Patients who have undergone thrombolytic therapy or endovascular therapy;
  2. Inability to cooperate sufficiently to complete the cerebral autoregulation examination (e.g., due to a condition such as agitation, drowsiness, arrhythmia, insufficient bilateral temporal bone windows, etc.) during the recording;
  3. Presence of other intracranial lesions, such as cerebrovascular malformations, cerebral venous thrombosis, tumors, and other brain lesions;
  4. severe hepatic and renal dysfunction or failure;
  5. Patients with hematological disease, abnormal coagulation function, bleeding tendency, and platelet <100×10^9/L;
  6. Individuals who had contraindication of remote ischemic conditioning, such as severe soft tissue injury, fracture or vascular injury in the upper extremities, venous thrombosis in the acute or subacute stage of upper extremities, arterial occlusive disease, subclavian artery stenosis ≥ 50%, or subclavian steal syndrome;
  7. pregnant or lactating women;
  8. Previous RIC treatment or similar treatment;
  9. Patients with a life expectancy of less than 3 months or patients who are unable to complete the study for other reasons;
  10. unwillingness to be followed up or poor treatment adherence;
  11. Individuals who are participating in other clinical studies, have participated in other clinical studies within 3 months prior to enrollment, or have participated in this research;
  12. Other conditions that the investigator considers inappropriate for enrollment.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: RIC
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.
Procedure: Remote ischemic conditioning
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.
Placebo Comparator: Sham RIC
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 60 mm Hg. RIC will be conducted twice daily for 7 consecutive days.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cerebral autoregulation at 7 days
Time Frame: 0 - 7 days
Difference in Cerebral autoregulation at 7 days after RIC/sham-RIC between two groups. Phase difference (PD) in degree can therefore serve as a useful tool in the evaluation of cerebral autoregulation. Continuous cerebral blood flow velocities (CBFV) in cm/s of bilateral middle cerebral artery will be assessed noninvasively using transcranial Doppler. Spontaneous arterial blood pressure (ABP) in mmHg will be simultaneously recorded using a servo-controlled plethysmograph on the left or right middle finger with an appropriate finger cuff size. Data on CBFV and ABP were processed using MATLAB using scripts developed by the research team. PD was then derived from transfer function analysis to assess the dynamic association between CBFV and ABP.
