Values are expressed as means ± SD. ∗ indicates P < 0.05. All comparisons were determined using two-tailed unpaired Student t-test. NP: nonpregnant women; HP: healthy pregnant women; SBP, DBP, MBP, and PP: systolic, diastolic, mean, and pulse pressure, respectively. pPP and cPP: peripheral and central pulse pressure, respectively. AIx@75: augmentation index adjusted to a heart rate of 75 beats/minute; PWV: pulse wave velocity; SD and DD: systolic and diastolic diameter, respectively; E _P: Peterson's or pressure-strain elastic modulus; CCA: common carotid artery; CIMT: carotid intima-media thickness.
