Prognostic Implications of AccuFFRangio-guided PCI in STEMI

February 8, 2022 updated by: Wuhan Asia Heart Hospital

Prognostic Implications of AccuFFRangio-based Functional Evaluation for Guiding Coronary Intervention for Non-IRA Stenosis in Patients With STEMI

This is a prospective, single-center clinical trial. AccuFFRangio (ArteryFlow Technology Co., Ltd., Hangzhou, China) is a novel method for evaluating the functional significance of coronary stenosis by computing the pressure in the vessel based on angiographic images. The aim of this study was to evaluate the diagnostic accuracy and prognostic implications of AccuFFRangio in patients with ST-segment elevation myocardial infarction (STEMI).

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.

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.

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.
Experimental: AccuFFRangio Group
STEMI patients with multiple lesions who met the requirements of the study were enrolled and received coronary angiography. First, the revascularization of the criminal vessel (PCI) was completed. The patients were randomly grouped and divided into AccuFFRangio Group and Angiography Group if the treatment results were good. The AccuFFRangio Group was defined as non-IRA of these patients who were treated with PCI after angio-FFR measurement with FFR≤0.8.
Other: AccuFFRangio-guided strategy
In this study, the AccuFFRangio-guided strategy will be applied to in the AccuFFRangio group in which calculation of the AccuFFRangio values of all target coronary arteries with lesions with diameter stenosis of ≥ 50% (visual estimation) and with suitability to PCI revascularization will be carried out. If AccuFFRangio ≤ 0.80, then simultaneous PCI revascularization of target blood vessels will be carried out. If AccuFFRangio > 0.80, then no PCI revascularization of target blood vessels will be carried out.
Active Comparator: Angiography Group
The Angiography Group was defined as PCI treatment for non-IRA when diameter stenosis > 70% based on angiographic results.
Other: Angiography-guided strategy
In this study, CAG-guided strategy will be used for the control group, i.e., in accordance with current guideline recommendations, all target coronary arteries with lesions with diameter stenosis of ≥ 70% (visual estimation) and suited for PCI revascularization will undergo PCI revascularization.

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
Vessel-oriented composite endpoints (VOCEs)
Time Frame: 1 year
Composite of vessel-related cardiovascular death, vessel-related myocardial infarction, and ischemia-driven target vessel revascularization.
1 year
Post-PCI AccuFFRangio
Time Frame: 1 year
AccuFFRangio limits to yield no VOCEs (Composite of vessel-related cardiovascular death, vessel-related myocardial).
1 year

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.
Outcome Measure
Measure Description
Time Frame
Cost analysis
Time Frame: 1 year
Cost savings of AccuFFRangio-guided strategy. Evaluation of costs by excess/reduced need for PCI when AccuFFRangio and Angiography disagree.
1 year
Prognostic implications
Time Frame: 1 year
The time from randomization to first occurrence of any of composite outcome including vessel-related cardiovascular death, vessel-related myocardial infarction, and ischemia-driven target vessel revascularization.
