The mean of systolic blood pressure (SBP), diastolic blood pressure (DBP), the average blodd pressure (ABP) and systolic pressure overload (PO) of male were 136.9 ± 7.1; 86.1 ± 5.9; 106.0 ± 5.6 (mmHg) và 48.2 ± 17.5 (%) higher than hypertension group having MS of female (132.2 ± 7.5; 81.5 ± 6.2; 101.3 ± 5.8 (mmHg) và 31.7 ± 13.4 (%) with statistical significance (p < 0.01). Conclusions: In the primary hypertensive patients with MS, the value of hypertension, 24 hour systolic pressure overload were higher than the primary hypertensive patients without MS.
