    Assessment of Subclinical Atherosclerosis by Carotid Intima-Media Thickness and Epicardial Adipose Tissue Thickness in Prediabetes
    (2016) Altin, Cihan; Sade, Leyla Elif; Gezmis, Esin; Ozen, Necmi; Duzceker, Ozkan; Bozbas, Huseyin; Eroglu, Serpil; Muderrisoglu, Haldun; 0000-0002-1001-6028; 0000-0003-3737-8595; 0000-0002-9635-6313; 0000-0003-3055-7953; 27069111; AAE-8301-2021; AAQ-7583-2021; ABG-1582-2021; AAG-8233-2020
    Impaired fasting glucose (IFG) and impaired glucose intolerance (IGT) are predictors of cardiovascular disease (CVD). We tested the hypothesis that epicardial fat thickness (EFT) and carotid intima-media thickness (cIMT), as markers of early atherosclerosis, are increased in patients with prediabetes. We prospectively enrolled 246 patients (162 with prediabetes and 84 controls). Prediabetes was defined according to American Diabetes Association criteria, and patients were divided into 3 groups: group 1IFG, group 2IGT, and group 3IFG + IGT. Both cIMT and EFT were significantly greater in patients with prediabetes compared with controls (0.81 +/- 0.20 mm vs 0.68 +/- 0.16 mm, P < .001 and 7.0 +/- 2.0 mm vs 5.6 +/- 1.6 mm, P < .001, respectively). This difference was mainly attributed to patients with IGT. Age, waist circumference, and 2-hour glucose independently predicted cIMT, while 2-hour glucose was the only independent predictor of EFT in multivariate analysis among other relevant parameters for cIMT and EFT. The cIMT and EFT (measured noninvasively) could be useful indicators of CVD risk in these patients. In order to prove this hypothesis, long-term prospective studies with greater patient numbers are required.

    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.

    Parathyroid Hormone and Ischemic Cerebrovascular Event
    (2019) Altay, Hakan; Altin, Cihan; Coner, Ali; Muderrisoglu, Haldun; Giray, Semih; 0000-0002-9635-6313; 0000-0002-0722-3181; 30806331; AAG-8233-2020; AAH-1091-2020
    Background: Increased parathyroid hormone (PTH) level is associated with coronary artery disease, hypertension and left ventricular hypertrophy which are all predisposing factors for the ischemic cerebrovascular event ( ICVE). Carotid intima-media thickness (CIMT) and aortic distensibility are the two early, subclinical predictors of atherosclerosis. The relation of PTH with CIMT and aortic distensibility in patients with ICVE has not been previously studied. Objective: Our aim was to study the relationship of PTH levels with aortic distensibility and CIMT in patients with ICVE. Methods: Sixty-four ICVE patients and 50 control group were enrolled in the study. PTH levels, aortic distensibility and CIMT were measured in all individuals. Results: PTH levels were significantly higher in ICVE patients than in the controls (60.1 +/- 21.6 vs. 52.3 +/- 6.2 pg/ml) (p=0. 008). PTH levels were found to be inversely correlated with aortic distensibility (r= -0. 420, p=0.001) and positively correlated with CIMT ( r:0, 285, p=0,002). Conclusion: The present study shows that PTH levels are increased in patients with acute ischemic cerebrovascular event compared to the control group. It also demonstrates that PTH levels are inversely related to aortic distensibility of ascending aorta and positively associated with CIMT.
