In univariate analysis, VAP-1 correlated with presence of diabetes (r = 0.29, p < 0.05), presence of hypertension (r = 0.23, p < 0.05), ejection fraction (r = −0.43, p < 0.01), cholesterol (r = −0.23, p < 0.05), serum iron (r = −0.23, p < 0.05), ferritin (r = −0.28, p < 0.05). The gene discussed is AOC3; the disease is Hypertension.
