Stratified analyses of the difference hypotensive effects of α,β-ADR blockers between KCNH2 (1956,C>T) genotypes(CC v.s CT+TT) and age(≤55 y v.s 55 y), gender(Men v.s Women)interactions in EH patients.

*P-values were with bonferroni adjust and BMI, gender ,age adjust were appropriately use in the model,ΔHR4 = heart rate change at the end of 4 weeks, ΔDBP4 = diastolic pressure change at the at the end of 4 weeks,ΔMAP4 = mean arterial pressure change at the at the end of 4 weeks, ΔPP4 = pulse pressure change at the end of 4 weeks, ΔDBP6 = diastolic pressure change at the end of 6weeks, ΔMAP6 = mean arterial pressure change at the end of 6 weeks.
