Abstract

ObjectiveLimited evidence has been available on the relationships of cellular growth factors with cardiovascular disease in population-based samples.MethodsWe conducted a nested case-control study under a large prospective cohort study (JACC study) where a total of 39,242 subjects aged 40-79 years provided serum sample. We measured cellular growth factors [insulin-like growth factors I, II and binding protein-3 (IGF-I, IGF-II and IGFBP-3) and transforming growth factor (TGF-β1)] among cases and controls, matched for sex, age, area of residence and year of serum storage.Results and conclusionsDuring the follow-up for 9 years, there were 233 deaths from total stroke (49 subarachnoid hemorrhages, 55 intraparenchymal hemorrhages, 71 ischemic strokes), and 97 deaths from coronary heart disease. The multivariable odds ratio (95%CI) of intraparenchymal hemorrhage associated with a 1-SD increment of IGF-I (men:4 8 ng/ml, women: 61 ng/ml) was 0.31 (0.14-0.71). That of ischemic stroke associated with a 1-SD increment of TGF-β1 (men: 8.0 ng/ml, women: 10.9 ng/ml) was 0.58 (0.34-0.98). Serum IGF-II and IGFBP-3 were not associated with mortality from any outcomes. In conclusion, IGF-I was inversely associated with mortality from intraparenchymal hemorrhage while TGF-β1 was so with ischemic stroke, suggesting potential roles of cellular proliferation in the development or prognosis of stroke.

▸ Limited evidence on the relationships between cellular growth factors and CVD. ▸ Lower IGF-I was associated with higher mortality from intraparenchymal hemorrhage. ▸ Lower TGF-β1 was associated with higher mortality from ischemic stroke. ▸ These cellular growth factors may contribute the development or prognosis of stroke.
