As indicated in Table 3, male and female patients with EH complicated by CHF with preserved LV systolic function characterized by significant positive associations of IL-6 with LVMI, LAVI, E/e’ ratio, SBP (p < 0.001 for all indicators in each group), RWT (for males: p < 0.001, for females: p = 0.003), and DBP (for males: p < 0.001, for females: p = 0.003). This evidence concerns the gene IL6 and congestive heart failure.
