ECG-guided Immediate Primary PCI for Culprit Vessel to Reduce Door to Device Time

May 31, 2022 updated by: Beijing Luhe Hospital

ECG-guided Immediate pRimAry Percutaneous Coronary Intervention for Culprit Vessel Using a Transradial Single Guiding Catheter to Reduce Door to Device Time: RAPID II Study

No consensus exists about which coronary artery should be firstly catheterized in primary percutaneous coronary intervention (PCI). The aim of the present study was to compare door-to-balloon time (D2B) of ECG guided immediate infarct-related artery (IRA) PCI with traditional complete coronary angiography followed by PCI for the treatment of ST segment elevation myocardial infarction (STEMI) patients. Primary endpoint is door to device (D2D) time. Secondary end-points are: puncture to device (P2D) time,first medical contact to device (FMC2D) time,incidence of radial artery spasm and occlusion, contrast amount, fluoroscopy time, cumulative air kerma(CAK) and dose area product(DAP).

Study Overview

Status

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

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.

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.

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
door to device (D2D) time
Time Frame: 24hours
time patient's arrival at our hospital to first device (balloon,aspiration catheter or stent) use
24hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment.
