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

Sampling Method

Non-Probability Sample

Study Population

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
the composite of death, nonfatal myocardial infarction (MI), or ischemic-driven Target- Vessel Revascularization (TVR)
Time Frame: 12 months

the composite of death, nonfatal myocardial infarction (MI), or ischemic-driven Target- Vessel Revascularization (TVR) at 12 months post procedure.

A composite endpoint is an endpoint that is a combination of multiple clinical endpoints. An event is considered to have occurred if any one of several different events is observed.
12 months

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
the event rate of all cause death
Time Frame: 5 years
5 years
the event rate of cardiac death
Time Frame: 5 years
5 years
the event rate of Target- Vessel Revascularization (TVR)
Time Frame: 5 years
5 years
the event rate of Target- lesion Revascularization (TLR)
Time Frame: 5 years
5 years
the event rate of stent thrombosis
Time Frame: 5 years
according to an Academic Research Consortium (ARC) criteria
5 years
the event rate of stroke
Time Frame: 5 years
5 years
the event rate of myocardial infarction
Time Frame: 5 years
5 years
the composite event rate of death, or myocardial infarction (MI)
Time Frame: 5 years
5 years
the composite event rate of cardiac death, or myocardial infarction (MI)
Time Frame: 5 years
5 years
the event rate of Procedural success
Time Frame: 5 days
defined as achievement of a final diameter stenosis of <30% by visual estimation, without the occurrence of death, Q-wave MI, or urgent revascularization during the index hospitalization.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

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.
January 9, 2025

Primary Completion (Estimated)

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.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
