    Background Serum uric acid is related to hypertension and cardiovascular diseases. Masked hypertension is associated with an increase in cardiovascular risk. The aim of our study was to evaluate the serum uric acid level and its relationship with carotid intima-media thickness (IMT) in patients with masked hypertension. Subjects and methods A total of 114 untreated masked hypertension patients (62 men, 52 women; mean age 44.6 +/- 7.9 years) and 38 controls (20 men, 18 women; mean age 44.8 +/- 7 years) were included in the study. All patients underwent 24-hour ambulatory blood pressure. Serum uric acid and carotid IMT were measured. Results Serum uric acid was significantly higher in masked hypertension patients when compared to the control group (5.14 +/- 1.42 mg/dl, 4.84 +/- 1.45 mg/ dl, P=0.01). Masked hypertension patients had significantly higher carotid IMT than control subjects (0.58 +/- 0.09, 0.52 +/- 0.09, P < 0.001). The masked hypertension group was also divided into two groups according to the median value of the serum uric acid levels (median value: 5 mg/dl). Carotid IMT was significantly higher in patients with a higher uric acid when compared to those with a lower uric acid (P < 0.001). We also found that the serum uric acid level was a good predictor of increased carotid IMT at the receiver-operating characteristic curve. The area under the curve was 66% (95% confidence interval, 0.56-0.77), and the serum uric acid level was significantly predictive of a high carotid IMT (P=0.001). Conclusions Our data suggest that the uric acid levels were significantly higher in the masked hypertension group and elevated uric acid levels were associated with increased carotid IMT, indicating that elevated serum uric acid levels might contribute to the increase in cardiovascular risk in masked hypertension.

    Morning Blood Pressure Surge Is Associated with Carotid Intima-Media Thickness in Prehypertensive Patients
    (2017) Alpaydin, Sertac; Turan, Yasar; Caliskan, Mustafa; Caliskan, Zuhal; Aksu, Feyza; Ozyildirim, Serhan; Buyukterzi, Zafer; Kostek, Osman; Muderrisoglu, Haldun; https://orcid.org/0000-0002-9635-6313; 28272109; AAG-8233-2020
    Objective Morning blood pressure (BP) surge (MBPS) is defined as an excessive increase in the morning BP from the lowest systolic BP during sleep and is reported as a risk factor for cardiovascular events in current clinical studies. In this study, we aimed to investigate the relationship between MBPS and carotid intima-media thickness (C-IMT) in prehypertensive patients. Patients and methods We evaluated the association between the rate of BP variation derived from ambulatory BP monitoring and C-IMT in patients with prehypertension. Results One hundred and seventy patients with prehypertension were included in the study. All office BP measurements and ambulatory 24-h, day-time, and night-time measurements were similar between each group. C-IMT [0.60 (range: 0.57-0.65) vs. 0.55 (range: 0.50-0.60) cm; P < 0.001] and the mean platelet volume [8.7 (range: 7.9-9.1) vs. 7.9 (range: 7.3-8.8) fl; P = 0.002] were significantly higher in the greater MBPS group than the lower group. In multivariate analysis, male sex [odds ratio (OR): 2.271, confidence interval (CI): 1.011-5.100, P = 0.047], greater MBPS (OR: 8.474, CI: 3.623-19.608, P < 0.001), and elevated mean platelet volume levels (OR: 3.359, CI: 1.978-5.705, P < 0.001) were found to be independent predictors of greater C-IMT in prehypertensive patients. Conclusion Our study suggests that greater MBPS is associated independently with C-IMT in prehypertensive patients. Copyright (C) 2017 Wolters Kluwer Health, Inc. All rights reserved.
