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.Free PDF Download
