In addition, stratification by control source indicated an increased risk of CAD susceptibility with the rs699947 polymorphism for population-based studies of reduced heterogeneity.
We were unable to find strong association between analyzed polymorphisms in growth factors and the severity of coronary artery disease, although there was a trend toward association between rs699947 and the severity of CAD in patients without previous MI.
The possible association of rs699947 and rs2010963 with CAD risks warrant confirmation in independent case-control studies and may be informative for future investigations on the pathogenesis of CAD.
Logistic regression analyses revealed that the VEGFA rs699947 C/A, VEGFA rs2010963 G/C, and VEGFA rs3025039 C/T polymorphisms were not associated with a risk of CAD.
This study tested the association between functional VEGF +405 C>G (rs2010963), -2578C>A (rs699947) polymorphisms, and coronary collaterals in patients with coronary artery disease (CAD).
