Publication Metadata only Acute sleep deprivation is associated with increased arterial stiffness in healthy young adults(SPRINGER HEIDELBERG, 2014) SARI, İBRAHİM; Sunbul, Murat; Kanar, Batur Gonenc; Durmus, Erdal; Kivrak, Tarik; Sari, IbrahimBackground Arterial stiffness and its hemodynamic consequences are known to be associated with increased cardiovascular morbidity and mortality. Pulse wave velocity (PWV) and augmentation index (AIx) are noninvasive indicators of the arterial stiffness and wave reflection. Sleep deprivation (SD) is known to be associated with increased incidence of adverse cardiovascular events. The aim of this study was to investigate whether there is an association between acute SD and arterial stiffness parameters in healthy adults, which has not been studied previously. Methods The study population consisted of 42 healthy volunteers (18 males, mean age 30.0 +/- 4.5 years). Measurements of arterial stiffness were carried out by using a Mobil-O-Graph arteriograph system. Arterial stiffness measurements were obtained both after a night with regular sleep (RS) and after a night with SD. Results Mean sleep time was significantly lower after the night of SD when compared after RS (0.73 +/- 1.39 versus 7.33 +/- 0.52 h, p < 0.001). Peripheral systolic blood pressure, peripheral pulse pressure, and cardiac output were significantly higher after SD when compared after RS (p = 0.032, 0.007, and 0.003, respectively). PWVwas significantly higher (5.33 +/- 0.46 versus 5.15 +/- 0.26 m/s, p = 0.001), and AIx was significantly lower (20.5 +/- 11.9 versus 26.0 +/- 8.4 %, p = 0.008) after the night of SD when compared after the RS. While PWV was significantly higher (p= 0.008), and AIx was significantly lower (p = 0.039) in male subjects, only PWVwas significantly higher (p = 0.009) in female subjects. Sleep time correlated with AIx (p = 0.034; r = 0.233) and inversely correlated with PWV (p = 0.044; r = -0.222). Conclusion In the present study, we demonstrated that even one night of SD is associated with increased arterial stiffness in healthy adults. The present findings suggest that adverse effects of SD on cardiovascular system might be at least in part due to increased arterial stiffness which needs to be tested with large-scale studies and in the chronic SD setting.Publication Metadata only Assessment of arterial stiffness and cardiovascular hemodynamics by oscillometric method in psoriasis patients with normal cardiac functions(SPRINGER, 2015) SEÇKİN GENÇOSMANOĞLU, DİLEK; Sunbul, Murat; Seckin, Dilek; Durmus, Erdal; Ozgen, Zuleyha; Bozbay, Mehmet; Bozbay, Ayfer; Kivrak, Tarik; Oguz, Mustafa; Sari, Ibrahim; Ergun, Tulin; Agirbasli, MehmetArterial stiffness is associated with increased cardiovascular risk. Pulse wave velocity (PWV) and augmentation index (AIx) are non-invasive markers for assessment of arterial stiffness. Increased arterial stiffness is associated with atherosclerosis in patients with psoriasis. Previous studies have shown that high neutrophil-to-lymphocyte ratio (NLR) predicts poor cardiovascular outcome. The aim of this study was to evaluate arterial stiffness and cardiovascular hemodynamics by oscillometric method in psoriasis patients with normal cardiac functions. Fifty consecutive patients with the diagnosis of psoriasis and 50 controls were included in the study. NLR was calculated as the ratio of neutrophil count to lymphocyte count. All patients underwent echocardiographic examination. Measurements of arterial stiffness were carried out using a Mobil-O-Graph arteriograph system. Fifty patients with psoriasis (26 male, mean age 43.3 +/- 13.2 years) and 50 controls (33 male, mean age 45.0 +/- 6.1 years) were included into the study. The distribution of cardiovascular risk factors was similar between the two groups, and NLR was significantly higher in patients with psoriasis (2.74 +/- 1.78 versus 1.82 +/- 0.52, p = 0.002). There was a weak correlation between NLR and PASI score without reaching statistical significance (r = 0.300, p = 0.060). While echocardiographic and hemodynamic parameters were comparable between psoriasis and control groups, heart rate was significantly higher in psoriasis group (81.5 +/- 15.1 and 75.2 +/- 11.8 beats/min, p = 0.021). Psoriasis patients had significantly higher AIx and PWV values as compared to controls (25.8 +/- 13.1 versus 17.4 +/- 12.3 %, p = 0.001 and 6.78 +/- 1.42 versus 6.18 +/- 0.80 m/s, p = 0.011, respectively). AI and PWV were significantly associated with psoriasis when adjusted by heart rate (p = 0.005, odds ratio 1.04, 95 % confidence interval 1.01-1.08 and p = 0.035, odds ratio 1.52, 95 % confidence interval 1.02-2.26, respectively). PWV significantly correlated with blood pressure, lipid levels, and several echocardiographic indices. AIx only correlated with left atrial diameter (r = 291, p = 0.040). Linear regression analysis was performed to find predictors of PWV. Central systolic blood pressure, left atrial diameter, and total cholesterol were independent predictors of PWV. PWV and AIx were significantly higher in patients with psoriasis. Assessment of arterial stiffness parameters may be useful for early detection of cardiovascular deterioration in psoriasis patients with normal cardiac functions. Novel inflammatory biomarkers such as NLR may elucidate the mechanism of vascular dysfunction in such patients.Publication Open Access Increased arterial stiffness parameters in panic disorder patients in long term treatment period(BMC, 2016-12) SARI, İBRAHİM; Yanartas, Omer; Sunbul, Murat; Senkal, Zeynep; Durmus, Erdal; Kivrak, Tarik; Subasi, Nilufer; Karaer, Gulhan; Ergun, Serhat; Sari, Ibrahim; Sayar, KemalBackground: The relationship between mental stress and cardiovascular disease has been shown in several studies. Panic disorder (PD) is also associated with cardiovascular disease due to increased risk of myocardial infarction. The aim of this study is to evaluate the association between arterial stiffness parameters and depression/anxiety scores in patients with PD. Methods: The study population consisted of 25 patients with PD and 25 age-sex-matched healthy controls. Depression and anxiety levels were evaluated by Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI), respectively. Determination of arterial stiffness parameters was conducted using a Mobil-O-Graph arteriograph system that detected signals from the brachial artery. Results: While baseline characteristics were similar between two groups, BDI and BAI scores were significantly higher in patients with PD (p < 0.005). The pulse wave velocity (PWV) and Augmentation Index (AIx) were also significantly higher in patients with PD (p = 0.001, p = 0.006). There was a moderate correlation between PWV and AIx with BAI scores (r = 0.442, p = 0.001, r = 0.441, p = 0.001). AIx was also positively correlated with BDI scores (r = 0.415, p = 0.03). Conclusion: We demonstrated a significant relationship between arterial stiffness parameters and anxiety/depression scores in patients with PD who receive antidepressant treatment.Publication Open Access Arterial stiffness parameters associated with vitamin D deficiency and supplementation in patients with normal cardiac functions(AVES, 2016) ÇİNÇİN, AHMET ALTUĞ; Sunbul, Murat; Cincin, Altug; Bozbay, Mehmet; Mammadov, Ceyhun; Atas, Halil; Ozsenel, Ekmel Burak; Sari, Ibrahim; Basaran, YeldaObjective: Arterial stiffness parameters including pulse wave velocity (PWV) and augmentation index (AIx) are associated with increased risk of cardiovascular disease. A close relationship has been demonstrated between vitamin D deficiency and cardiovascular disease. The aim of the present study was to investigate effects of vitamin D deficiency and supplementation on arterial stiffness parameters in patients with normal cardiac functions. Methods: Study population consisted of 45 patients with vitamin D deficiency and normal cardiac functions. Median age (interquartile range) was 45.0 (12.00) years, and 33 patients were female. Patients were treated with oral administration of vitamin D3. Arterial stiffness parameters were evaluated using Mobil-O-Graph arteriograph system, which detected signals from the brachial artery before and after treatment. Results: Vitamin D levels significantly increased after treatment (9.0 [6.00] nmol/L vs 29.0 [11.50] nmol/L, p<0.001). No significant difference was observed among conventional echocardiographic parameters before or after treatment. Post-treatment PVW and AIx were significantly lower than baseline measurements (6.8 [1.55] m/s vs 6.4 [1.30] m/s, p<0.001 and 23.0 [22.00]% vs 31.0 [14.50]%, p<0.001, respectively). Baseline vitamin D levels significantly correlated with PWV (r=-0.352, p=0.018). Post-treatment vitamin D levels also significantly correlated with post-treatment PWV (r=-0.442, p=0.002) and AIx (r=-0.419, p=0.004). Multivariate linear regression analysis revealed no independent predictor of baseline log-transformed PWV. Conclusion: Vitamin D supplementation has beneficial effects on arterial stiffness. Arterial stiffness parameters may aid in the assessment of cardiovascular risk in patients with vitamin D deficiency.
