At multivariate regression analysis (Table 2), MCP-1 was an independent predictor of SS (RC [Regression Coefficient] = 1.73 for each increase of 50 pg/mL, [95%CI = 0.08–3.39]; p = 0.040) along with NT-proBNP (RC = 0.17 for each increase of 100 pg/mL, [95% CI = 0.05–0.28]; p = 0.004), male sex (RC = 4.15 [95%CI = 1.47–6.83]; p = 0.003), age (RC = 0.13 for each increase of 5 years, [95%CI = 0.02–0.24]; p = 0.020), hypertension (RC = 3.64 [95%CI = 0.77–6.50]; p = 0.013), hyperlipidemia (RC = 2.78 [95%CI = 0.28–5.29]; p = 0.030) and statins (RC = 6.12 [95%CI = 1.28–10.96]; p = 0.013). This evidence concerns the gene NPPB and hypertensive disorder.
