Background-Fibroblast growth factor-23 (FGF-23) is a phosphate regulatory hormone that directly stimulates left ventricular hypertrophy in experimental models. The role of FGF-23 in cardiovascular disease development in the general population is unclear. We tested associations of FGF-23 with major subclinical and clinical cardiovascular disease outcomes in a large prospective cohort. Methods and Results-We evaluated 6547 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) who were initially free of cardiovascular disease. We measured serum FGF-23 using the Kainos immunoassay. The MESA measured left ventricular mass by MRI, coronary calcium by computed tomography, and carotid intima-media thickness by ultrasound. The MESA adjudicated incident heart failure, coronary heart disease, and stroke by medical record review. After adjustment, the highest FGF-23 quartile was associated with an estimated 2.4-g greater left ventricular mass (95% confidence interval, 0.4-4.5 greater) and a 26% greater odds of higher coronary calcium scores (95% confidence interval, 9%-46% greater) compared with the lowest quartile. During 7.5-year follow-up, each 20-pg/mL higher FGF-23 concentration was associated with a 19% greater risk of heart failure (95% confidence interval, 3%-37% greater) and a 14% greater risk of coronary heart disease (95% confidence interval, 1%-28% greater). FGF-23 was not associated with carotid intima-media thickness or stroke. Conclusions-Higher serum FGF-23 concentrations are associated with subclinical cardiac disease and with new heart failure and coronary disease events, but not with carotid intima-media thickness or stroke. FGF-23 may be a novel cardiovascular risk factor in the general population.
