- Objective-Rupture of atherosclerotic plaques is the major cause of acute coronary events (CEs). Plaque destabilization is the consequence of an imbalance between inflammatory-driven degradation of fibrous tissue and smooth muscle cell-dependent tissue repair. Proinflammatory factors have been documented extensively as biomarkers of cardiovascular risk but factors that contribute to stabilization of atherosclerotic plaques have received less attention. The present study aimed to investigate whether plasma levels of the smooth muscle cell growth factor epidermal growth factor (EGF), heparin-binding-EGF (HB-EGF), and platelet-derived growth factor correlate with plaque phenotype and incidence of CEs. Approach and Results-HB-EGF, EGF and platelet-derived growth factor were measured in plasma from 202 patients undergoing carotid endarterectomy and in 384 incident CE cases and 409 matched controls recruited from the Malmo Diet and Cancer cohort. Significant positive associations were found between the plasma levels of all 3 growth factors and the collagen and elastin contents of the removed plaques. CE cases in the Malmo Diet and Cancer cohort had lower levels of HB-EGF in plasma, whereas no significant differences were found for EGF and platelet-derived growth factor. After adjusting for cardiovascular risk factors in a Cox proportional hazard model, the hazard ratio for the highest HB-EGF tertile was 0.61 (95% confidence interval, 0.47-0.82; P<0.001). Conclusions-The associations between high levels of smooth muscle cell growth factors in plasma and a more fibrous plaque phenotype as well as the association between low levels of HB-EGF and incident CEs point to a potential clinically important role for factors that contribute to plaque stabilization by stimulating smooth muscle cells.
