Abstract
<p>Serum thrombospondin-2 (TSP-2) is a glycoprotein expressed in the extracellular matrix (ECM), which increases during tissue remodeling. It has been shown in recent studies that TSP-2 is a useful predictor of cardiovascular death in patients with heart failure (HF). However, the clinical importance of serum TSP-2 levels in a general population is still unknown. Therefore, we aimed to clarify the association between TSP-2 and clinical risk factors. A periodic epidemiological survey was performed in a community dwelling in the town of Uku, Nagasaki, Japan. A total of 445 residents received a health checkup examination including blood tests such as fasting serum levels of TSP-2. Uni- and multivariate analyses were performed to examine the relationship between TSP-2 and clinical risk factors. All statistical analyses were performed using SAS v9.4 program. The mean ± standard deviation of age was 67.0 ± 9.4 years old. Although serum TSP-2 levels (mean: 20.9 ± 8.5 ng/mL) showed no significant sex difference, they were significantly correlated with the levels of plasma glucose (P < 0.001), insulin (P < 0.01), homeostasis model assessment of insulin resistance (HOMA-IR) (P < 0.001), estimated glomerular filtration rate (eGFR) (P < 0.01, inversely), high-sensitivity C-reactive protein (hs-CRP) (P < 0.001), history of atrial fibrillation (P < 0.001), history of cardiovascular diseases (P < 0.001), and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) (P < 0.001). Moreover, in the multiple stepwise linear regression analysis, the levels of TSP-2 were independently and significantly associated with the history of atrial fibrillation (P < 0.0001), HOMA-IR (P < 0.001), high-sensitivity CRP (P = 0.011), and NT-proBNP (P = 0.043). These results indicated the significant relationship between TSP-2 and clinical risk factors in a general population, suggesting its role as a predictor of heart disease morbidity and mortality.</p>
