Pre-pregnancy endothelial dysfunction and birth outcomes: The Coronary Artery Risk Development in Young Adults (CARDIA) Study.

ABSTRACT: Endothelial dysfunction is a form of subclinical cardiovascular disease that may be involved in preterm birth and small-for-gestational-age deliveries. However, concentrations of biomarkers of endothelial dysfunction before pregnancy have rarely been measured. We hypothesized that higher levels of biomarkers of endothelial dysfunction (cellular adhesion molecules and selectins) would be associated with odds of preterm birth and/or small-for-gestational-age deliveries. We included 235 women from the Coronary Artery Risk Development in Young Adults (CARDIA) study who were nulliparous at Y7, reported ?1 live birth through Y25, and had ?1 biomarker measured at Y7. We tested for associations between individual biomarkers and an averaged z-score representing total endothelial dysfunction with preterm birth and/or small-for-gestational-age deliveries using Poisson regression, adjusted for demographic and clinical characteristics at the exam immediately preceding index birth. At Y7, total evidence of endothelial dysfunction was similar in women who did (n?=?59) and did not have (n?=?176) preterm birth and/or small-for-gestational-age deliveries. There was no association between biomarkers of endothelial dysfunction (either individual biomarker or total score) with odds of preterm birth and/or small-for-gestational-age deliveries after adjustment: IRR?=?1.01, 95% CI: 0.74, 1.39, p?=?0.93 for total endothelial biomarker score. Associations were not modified by race. We conclude that biomarkers of endothelial dysfunction in nulliparous women, measured ~3 years before pregnancy, did not identify women at risk for preterm birth and/or small-for-gestational-age deliveries. This suggests that the maternal endothelial dysfunction that is believed to contribute to these birth outcomes may not be detectable before pregnancy.

Project description:BackgroundElevated Fibroblast Growth Factor-23 (FGF23) levels have been associated with greater left ventricular mass (LVM) and heart failure. Whether higher FGF23 is associated with higher LVH prevalence and longitudinal changes in LVM and myocardial strain in middle-aged adults without cardiovascular disease (CVD) or chronic kidney disease (CKD) is unknown.MethodsWe studied 3,113 adults without CVD at baseline participating in the Year 25 (2010-2011) follow-up exam of the Coronary Artery Risk Development in Young Adults (CARDIA) study. We studied the association of Year 25 c-terminal FGF23 concentrations with indexed LVM (LVMI=LVM/height2.7), LVH and myocardial strain as assessed by speckle tracking strain echocardiography. Among the 2,758 (88.6%) participants who returned for the Year 30 examination, we also investigated the association of Year 25 FGF23 with 5 Year change in LVMI, strain parameters and incident LVH.ResultsThe mean age was 50.0 (±3.6) years, 56.8% were female, 45.7% were Black and 6.4% had CKD. There was 6.0% LVH prevalence at Year 25. Mean 5 Year change in LVMI was 5.3 (±7.7) grams/meter. In multivariable models, FGF23 in the highest quartile was associated with greater odds of LVH at Year 25 compared to lower quartiles. [Odds Ratio 95% CI: 1.81 (1.28, 2.58)] with similar findings after exclusion of participants with CKD. There was no interaction between FGF23 and race (P = .18) or sex (P = .80). There was no association between FGF23 and global longitudinal strain. There was no association between FGF23 and 5 Year change in LVMI. There was no association between higher FGF23 and 5 year incident LVH.ConclusionsIn a middle-aged adult population without known CVD or CKD, higher FGF23 was associated with greater odds of LVH, but not with greater increases in LVM over time. Further study is needed to elucidate whether FGF23 is a risk marker for underlying LVH or a mechanism for increased LVM over time in younger and middle-aged adult populations without CKD.

Project description:BACKGROUND:Dyslipidemia causes coronary heart disease in middle-aged and elderly adults, but the consequences of lipid exposure during young adulthood are unclear. OBJECTIVE:To assess whether nonoptimal lipid levels during young adulthood cause atherosclerotic changes that persist into middle age. DESIGN:Prospective cohort study. SETTING:4 cities in the United States. PARTICIPANTS:3258 participants from the 5115 black and white men and women recruited at age 18 to 30 years in 1985 to 1986 for the CARDIA (Coronary Artery Risk Development in Young Adults) study. MEASUREMENTS:Low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, triglycerides, and coronary calcium. Time-averaged cumulative exposures to lipids between age 20 and 35 years were estimated by using repeated serum lipid measurements over 20 years in the CARDIA study; these measurements were then related to coronary calcium scores assessed later in life (45 years [SD, 4]). RESULTS:2824 participants (87%) had nonoptimal levels of LDL cholesterol (>or=2.59 mmol/L [>or=100 mg/dL]), HDL cholesterol (<1.55 mmol/L [<60 mg/dL]), or triglycerides (>or=1.70 mmol/L [>or=150 mg/dL]) during young adulthood. Coronary calcium prevalence 2 decades later was 8% in participants who maintained optimal LDL levels (<1.81 mmol/L [<70 mg/dL]), and 44% in participants with LDL cholesterol levels of 4.14 mmol/L (160 mg/dL) or greater (P < 0.001). The association was similar across race and sex and strongly graded, with odds ratios for coronary calcium of 1.5 (95% CI, 0.7 to 3.3) for LDL cholesterol levels of 1.81 to 2.56 mmol/L (70 to 99 mg/dL), 2.4 (CI, 1.1 to 5.3) for levels of 2.59 to 3.34 mmol/L (100 to 129 mg/dL), 3.3 (CI, 1.3 to 7.8) for levels of 3.37 to 4.12 mmol/L (130 to 159 mg/dL), and 5.6 (CI, 2.0 to 16) for levels of 4.14 mmol/L (160 mg/dL) or greater, compared with levels less than 1.81 mmol/L (<70 mg/dL), after adjustment for lipid exposure after age 35 years and other coronary risk factors. Both LDL and HDL cholesterol levels were independently associated with coronary calcium after participants who were receiving lipid-lowering medications or had clinically abnormal lipid levels were excluded. LIMITATION:Coronary calcium, although a strong predictor of future coronary heart disease, is not a clinical outcome. CONCLUSION:Nonoptimal levels of LDL and HDL cholesterol during young adulthood are independently associated with coronary atherosclerosis 2 decades later.
