PTRG-DES Consortium (PTRG)

March 15, 2022 updated by: Gyeongsang National University Hospital

Platelet Function and genoType-Related Long-term progGosis in DES-treated Patients : A Consortium From Multi-centered Registries

The PTRG-DES consortium is a coalition composed of multi-center, real-world registries including CAD patients treated with DES in South Korea. From 9 academic registries in Korea, a total of 13,160 patients were enrolled for this database between July 2003 and August 2018. The aim of the study was to investigate long-term prognostic implications of platelet function and genotypes after DES implantation for significant CAD in South Korea.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

The investigators enrolled patients treated with DES during DAPT including clopidogrel who had at least one of VerifyNow test (PRU and ARU) and genotyping. In this consortium, the investigators tried to find the unique characteristics of East Asians based on platelet function, genotype and inflammatory markers.

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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Significant CAD patients treated with uneventful DES implantation

Description

Inclusion Criteria:

  • Consecutive patients at every centre successfully treated with one or more DES approved by the US FDA or CE mark and who were adequately loaded with clopidogrel were eligible for enrolment, regardless of patient or lesion complexity.

Exclusion Criteria:

  • the occurrence of a major complication during the procedure or before platelet function testing, or if bypass surgery was planned after PCI.
  • Any P2Y12 inhibitor other than clopidogrel
  • PCI strategy other than DES
  • Needed oral anticoagulant (e.g. atrial fibrillation)

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
PTRG-DES registry

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
MACCE
Time Frame: upto 10 years
All-cause death, MI, stroke or stent thrombosis
upto 10 years

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

Major bleeding
Time Frame: upto 10 years

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. Types of outcome measures include primary outcome measure and secondary outcome measure.
