CCL11 and heart failure: However, a logistic regression model adjusted for heart failure showed an association between ACS and diminished levels of platelet-derived growth factor B’s (PDGF-B) active form of homozygous dimer PDGF-BB (OR 0.478, 95% CI 0.279–0.818, p = 0.007), increased levels of eotaxin (OR 1.538, 95% CI, 1.089–2.172, p = 0.015) and stem cell factor (SCF) (OR 2.258, 95% CI 1.078–4.728, p = 0.031).
