Beskrivning
Inclusion Criteria: Diabetics and non-diabetics, with or without known CV disease, who are admitted in the Department of Cardiology in the University General Hospital of Ioannina and the Catheterization Laboratory of 1st IKA Hospital in Athens and undergo coronary angiography at ages 18-90 for clinical purposes will be studied. 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 (with or without previous history of CAD).
-
Exclusion Criteria: Patients < 18 years old and > 90 years old at time of coronary angiography. Patients with a previous history of coronary revascularization procedure or moderate to severe stenosis will be excluded.

Case
Diabetic patients undergoing coronary angiography (both sexes), who are age 18-90, and admitted in the Department of Cardiology in the University General Hospital of Ioannina and Catheterization Laboratory of 1st IKA Hospital in Athens and undergo coronary angiography for clinical purposes will be studied.
Presence epicardial vessel stenosis (>50%), and multi-vessel disease will be recorded.
Excluded: previous history of revascularization procedure or moderate to severe stenosis.
Patient samples will be evaluated for quantitative levels of the biomarkers Lp(a) and OXPL/apoB.
IL-1 Genotypes, and other SNPs associated with CAD will be assessed in this group and related to levels of Lp(a) and oxidized phospolipids.
No interventions other than the post-hoc DNA testing will be performed.
|
Genotyping will be carried out by a CLIA-certified genotyping facility at ILI, Waltham MA.
DNA concentrations will be adjusted to a range compatible with multiple PCR conditions.
Genotyping will be accomplished by performing multiplex polymerase chain reactions (PCR) specifically targeting the surrounding sequences for the SNPs being studied.
A single base extension assay will be hybridized to a 48-plex microarray plate and read on a SNPstream Genotyping System (Beckman-Coulter).

Control
Non-diabeticpatients undergoing coronary angiography (both sexes), who are age 18-90, and admitted in the Department of Cardiology in the University General Hospital of Ioannina and Catheterization Laboratory of 1st IKA Hospital in Athens and undergo coronary angiography for clinical purposes will be studied.
Presence epicardial vessel stenosis (>50%), and multi-vessel disease will be recorded.
