Are increased oxidative stress and asymmetric dimethylarginine levels associated with masked hypertension

ABSTRACTObjective: In this study, our aim was to determine total oxidative stress and asymmetric dimethylarginine (ADMA) levels in patients with masked hypertension (MHT) and to examine their association with blood pressure. Methods: Fifty patients diagnosed with MHT and 48 healthy volunteers without any known chronic diseases have been included in this study. Results: When compared to the control group, patients with MHT had higher levels of mean ADMA (p < 0.001), total oxidant status (TOS) (p < 0.001), and oxidative stress index (OSI) (p < 0.001), and a lower mean total antioxidant status (TAS) (p < 0.001) level. While a positive correlation was determined between the systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels with ADMA, TOS, and OSI levels, a negative correlation was determined with the TAS level. During the stepwise multivariable logistic regression analysis, age (OR = 1.221; p = 0.003), body mass index (OR = 1.512; p = 0.005), low density lipoprotein (OR = 0.925; p = 0.01...
