Abstract
OBJECTIVE
The SYNTAX Score was recently developed to characterize the coronary vasculature with respect to the number of lesion's location, complexity, and functional impact and it is a quantitative scoring system to assist with patient selection for optimal revascularization strategy between percutaneous coronary intervention (PCI) and coronary artery by-pass surgery (CABG). b2-glycoprotein I (b2GPI), a plasma protein that binds cardiolipin, acts as a modulator of platelet aggregation and coagulation. Antibodies to b2GPI may have a role in atherosclerosis by inducing endothelial cell activation. We investigated the relationship between anti beta 2 GPI and severity of coronary artery stenosis by calculating the SYNTAX Score among patients undergoing CABG surgery.
PATIENTS AND METHODS
We prospectively investigate 612 patients who undergo elective coronary angiography between September 2012 and June 2013. Patients were evaluated for blood chemistry and anti-b2GPI IgA, IgM and IgG. Ninety seven patients with complete biochemical analysis including anti Beta 2 GPI antibodies and undergone CABG have been enrolled in this study. We divided patients in to 2 groups according to the SYNTAX scores. Group 1 included 48 patients with low SYNTAX scores (<23) and group 2 included 49 patients with intermediate and high SYNTAX scores (>23).
RESULTS
There was significant correlation between elevated anti b2GPI IgG levels and higher SYNTAX score which indicate advanced and complex CAD. In this study, lesion complexity increased progressively with increasing anti-b2GPI-IgG type of antibody levels. According to this findings, anti-b2GPI-IgG is a strong predictor of higher SYNTAX score.
CONCLUSIONS
In addition to the traditional risk factors for atherosclerosis, the proinflammatory and procoagulant activities of antiphospholipid antibodies appear to be important risk factors for atherosclerotic occlusive disease.
