NCT03150680

Brief Summary

The purpose of the research project is to investigate the potential association of 207 genetic polymorphisms with the complexity and the severity of coronary artery disease (SYNTAX score), along with the patients' response to clopidogrel and statin therapy. The aim of the study is to combine genetic, pharmacogenetic, clinical and laboratory data in order to create an algorithm (GEnetic Syntax Score-GESS) that will enable an individualized therapeutic patient approach.

Study Arms (3)

SYNTAX score = 0

Patients with nonobstructive CAD (≤50 % diameter stenosis)

Genetic: SNPs associated with CAD, SNPs associated with pharmacological response to clopidogrel and statins

0 < SYNTAX score <23

Low SYNTAX group

Genetic: SNPs associated with CAD, SNPs associated with pharmacological response to clopidogrel and statins

SYNTAX score >= 23

Intermediate-High SYNTAX group

Genetic: SNPs associated with CAD, SNPs associated with pharmacological response to clopidogrel and statins

Interventions

Genotyping will be carried out by Next-Generation Sequencing (NGS)

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients between 18 years to 90 years at entry, of both genders, who are admitted in the Department of Cardiology in the AHEPA University General Hospital of Thessaloniki and undergo coronary angiography for clinical purposes will be studied. Patients with a previous history of coronary artery disease will be excluded. The study includes subjects who 1) have suspected CAD and undergo a scheduled diagnostic angiogram for clinical reasons, and 2) are hospitalized because of an acute coronary syndrome and thus undergo diagnostic angiography (without previous history of CAD).

You may qualify if:

  • Patients giving voluntary written consent to participate in the study
  • Male or female patients between 18 years to 90 years at entry
  • Patients without previous history of CAD
  • Patients who are admitted in the Department of Cardiology in the AHEPA University General Hospital of Thessaloniki and undergo coronary angiography for clinical purposes

You may not qualify if:

  • Patients \< 18 years old and \> 90 years old at time of coronary angiography
  • Patients with a previous history of CAD
  • Cardiac Arrest at admission
  • Patients with serious concurrent disease and life expectancy of \< 1 year
  • Patients who refuse to give written consent for participation in the study

Biospecimen

Retention: SAMPLES WITH DNA

DNA will be extracted from obtained subject blood samples at the AHEPA University General Hospital of Thessaloniki. DNAs will be labeled by anonymized subject ID # (de-identified), and shipped to LABNET IAE - Private Reference Diagnostic Laboratory for genotyping and genetic analysis.
