  1. H-Tens = Hypertension; CAD + H-Tens = Coronary artery disease and hypertension; CAD = Coronary artery disease; Ctrl = Control. Values are presented as mean ± SD. The differences of continuous variables among the study groups were analyzed using one-way analysis of variance (ANOVA)/Kruskal-Wallis with post-hoc Tukey/Mann-Whitney U tests. *Significant difference (P<0.05)
