Favorable Cardiovascular Health Is Associated With Lower Hepatocyte Growth Factor Levels in the Multi-Ethnic Study of Atherosclerosis

Introduction: Hepatocyte growth factor (HGF) is a cytokine released in response to endothelial injury and a potential biomarker of cardiovascular disease (CVD) risk. We examined the association between cardiovascular health (CVH) and HGF in a multi-ethnic cohort of adults free from CVD at baseline.Methods: This cross-sectional study conducted between 2020 and 2021 used MESA baseline examination data (2000–2002) from 6,490 US adults aged 45–84 years. The independent variable was CVH measured by the CVH score and number of ideal metrics. The score was derived from seven metrics: smoking, body mass index, physical activity, diet, total cholesterol, blood pressure and blood glucose. Each metric was scored 0 points (poor), 1 point (intermediate) and 2 points (ideal). The total CVH score ranged from 0 to 14. An inadequate score was 0–8, average, 9–10 and optimal, 11–14. The dependent variable was logarithmically transformed HGF. We used regression analyses to estimate associations between CVH and HGF adjusting for sociodemographic factors.Results: Participants' mean (SD) age was 62 (10) years. Fifty-three percent were female. A one-unit increment in the CVH score was significantly associated with 3% lower HGF levels. Average and optimal CVH scores were significantly associated with 8% and 12% lower HGF levels, respectively, compared to inadequate scores. Additionally, a greater number of ideal metrics was associated with lower HGF levels.Conclusion: Favorable CVH was significantly associated with lower HGF levels in this ethnically diverse cohort. Interventions aimed at promoting and preserving favorable CVH may reduce the risk of endothelial injury as indicated by lower serum HGF levels.

Hepatocyte Growth

Background: Hepatocyte growth factor (HGF) is a cytokine released in response to vascular injury and a novel biomarker of cardiovascular disease (CVD) risk. However, the relationship between ideal cardiovascular health (CVH) and HGF is unknown. We examined whether ideal CVH is associated with lower HGF levels in a multi-ethnic cohort of adults free from clinical CVD at baseline. Methods: We analyzed data from the MESA study of 6,490 men and women aged 45-84 years. The independent variable was the CVH score derived from 7 metrics (smoking, body mass index, physical activity, diet, total cholesterol, blood pressure and blood glucose). Each metric was scored 0 points (poor), 1 point (intermediate) and 2 points (ideal). The total CVH score ranged from 0-14. An inadequate score was 0-8, average, 9-10 and optimal, 11-14. The number of ideal metrics was also counted. The dependent variable was logarithmically transformed HGF. We examined the association between the CVH score and HGF using linear regression models adjusted for age, sex, race/ethnicity, education, income, health insurance and study site. Results: The mean (SD) age of participants was 62 (10) years. Fifty-three percent were women. Participants with optimal CVH scores had the lowest HGF concentration [Median (IQR): 807 (678-962) pg/mL] compared to those with average [870 (740-1,036)] and inadequate scores [969 (821-1,159)]. A one-unit increment in the CVH score was significantly associated with a 3% lower HGF concentration (Table). Average and optimal CVH scores were also significantly associated with 8% and 12% lower HGF concentrations, respectively, compared to inadequate scores. Additionally, a greater number of ideal metrics was associated with lower HGF concentrations. Interactions by age, sex and race/ethnicity were not significant. Conclusion: In this ethnically diverse cohort, optimal CVH was significantly associated with lower HGF levels. Interventions aimed at promoting ideal CVH may reduce vascular injury as indicated by lower serum HGF levels.

Hepatocyte Growth

Introduction: Hepatocyte Growth Factor (HGF) is a mesenchymal cytokine linked to incident heart failure (HF), with recent data from our group showing a strong and independent association with HF with preserved ejection fraction (HFpEF). Cardiac MRI (cMRI) allows for precise analysis of morphologic changes in left ventricular (LV) structure. Increasing LV mass and concentric remodeling (defined by an increasing mass:volume ratio) are imaging markers of HFpEF risk. Whether HGF is associated with adverse LV remodeling over time is unknown. Hypothesis: Higher HGF will be associated with increasing LV mass, decreasing LV volume and increasing mass:volume ratio over 10 yrs. Methods: We studied 4762 participants of the MESA cohort, free of cardiovascular disease (CVD) and HF at baseline, who completed both HGF measurement and cMRI at baseline. Participants with LV EF<50% were excluded. Of these, 2855 completed a 2 nd cMRI at 10 yrs. We examined the cross-sectional and longitudinal associations of HGF and LV parameters using multivariable-adjusted linear mixed effect models. Results: The mean (SD) for age was 61 (10) yrs. Median (IQR) for HGF level was 888 pg/mL (745-1066); 53% women. At baseline, the 3 rd HGF tertile, compared to the 1 st , was associated with greater mass:volume ratio [relative difference 1.66 (0.43, 2.89)] and lower LV end diastolic volume [-1.87 mL (-3.45, -0.28)], after adjustment for CVD risk factors and NT- proBNP (model 2) [Table] . In longitudinal analysis, the 3 rd HGF tertile was also associated with increasing mass:volume ratio [difference in 10-yr change: 4.79 (2.73, 6.85)] and decreasing LV end diastolic volume [-4.97 (-7.10, -2.85)]. Conclusions: In a community cohort, higher HGF levels were independently associated with a concentric LV remodeling pattern of increasing mass:volume ratio and decreasing LV end diastolic volume over 10 yrs. This association may suggest an intermediate phenotype explaining the association of HGF with HFpEF risk.

Background: Fetal growth is determined by the interaction between mother and fetus using the placental interface throughout the pregnancy. Objective: To research apoptosis and appearance of hepatocyte growth factor (HGF) in placentas of different gestational ages and to describe the anthropometrical and clinical indices of mothers and newborns. Materials and Methods: The study material was obtained from 53 human immunodeficiency virus negative pregnant women of legal age without systemic diseases. The staining of placental apoptotic cells was processed by a standard in situ cell death detection kit. The detection of HGF was provided by the ImmunoCruz goat ABC Staining System protocol sc-2023. Relative distribution of positive structures was evaluated using the semiquantitative counting method. Results: The mean rank value of the amount of HGF-containing cells (cytotrophoblasts, syncytiotrophoblasts, extravillous trophoblasts, Höfbauer cells, and cells of extraembryonic mesoderm) was 1.61 ± 0.94. Apoptotic cells (cytotrophoblasts, syncytiotrophoblasts, extravillous trophoblasts, and cells of extraembryonic mesoderm) were found in all placental samples of various gestational ages (term 13.00 ± 13.05 and preterm 27.00 ± 18.25); in general, their amount decreased with advancing gestational age of the placenta (p < 0.01). Conclusion: Weight of a placenta directly depends on the gestational age and correlates with the main fetal anthropometrical parameters (weight, length, and head and chest circumferences). The decrease in HGF-containing and apoptotic cells with advancing gestation depends on the adaptation potential of the placenta, proving the other ways of cellular disposition. Key words: Pregnancy, Placenta, Gestational age, Apoptosis, Immunohistochemistry.
