Long-term Remote Ischemic Preconditioning Improve the Prognosis of Myocardial Infarction Patients With Emergency Reperfusion Therapy

January 10, 2017 updated by: Xuanwu Hospital, Beijing
Patients with acute myocardial infarction (AMI) are in critical condition. When primary percutaneous coronary intervention (PCI) was performing, no-reflow, reperfusion injury，heart failure, heart rupture, malignant arrhythmia maybe happen. It was reported remote ischemic preconditioning (RIPC) may play an effective endogenous cardiac protection. This study will investigate whether once RIPC before primary PCI or long-term RIPC can improve AMI patients short-term and long-term (1 year) prognosis. 400 STEMI patients undergoing primary PCI were randomly divided into 3 groups: long-term RIPC group (once preoperative RIPC and once RIPC/day after PCI), preoperative RIPC group (once preoperative RIPC), control group (without RIPC). Cardiac troponin (TNI), high-sensitivity C-reactive protein (hsCRP), adenosine, vascular endothelial growth factor (VEGF), hypoxia inducible factor-1 (HIF-1), echocardiography and magnetic resonance （MR）were detected 1 day, 1 month and 1 year after PCI. Patients will be followed up by telephone at the end of one year. The major adverse cardiovascular events (MACE) include cardiovascular death, spontaneous myocardial infarction, unplanned revascularization and stroke.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Enrollment (Anticipated)

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.
400

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.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

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.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2016

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
