    Neutrophil to lymphocyte and platelet to lymphocyte ratio in patients with dipper versus non-dipper hypertension
    (TAYLOR & FRANCIS INC, 2014) ÇİNÇİN, AHMET ALTUĞ; Sunbul, Murat; Gerin, Fethullah; Durmus, Erdal; Kivrak, Tarik; Sari, Ibrahim; Tigen, Kursat; Cincin, Altug
    Background: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are associated with worse outcome in various diseases. Non-dipping blood pressure pattern is associated with higher cardiovascular mortality. The aim of this study was to explore the association between NLR and PLR in patients with dipper versus non-dipper hypertension. Methods: The study included 166 patients with hypertension. Eighty-three patients (40 male, mean age: 49.1 +/- 10.5 years) had dipper hypertension, while 83 patients (41 male, mean age: 52.3 +/- 12.7 years) had non-dipper hypertension. Results: Baseline demographic characteristics were similar in both groups. Patients with non-dipper hypertension had significantly higher NLR compared to dipper hypertension (2.3 +/- 0.9 versus 1.8 +/- 0.5, p < 0.001). Patients with non-dipper hypertension had significantly higher PLR compared to dipper hypertension (117.7 +/- 35.2 versus 100.9 +/- 30.5, p = 0.001). In univariate analysis, hyperlipidemia, smoking, presence of diabetes, PLR more than 107 and NLR more than 1.89 were among predictors of dipper and non-dipper status. In logistic regression analyses, only hyperlipidemia (odds ratio: 2.96, CI: 1.22-7.13) and PLR more than 107 (odds ratio: 2.62, Cl: 1.13-6.06) were independent predictors of dipper and non-dipper status. A PLR of 107 or higher predicted non-dipper status with a sensitivity of 66.3% and specificity of 68.7%. Conclusion: We demonstrated that patients with non-dipper hypertension had significantly higher NLR and PLR compared to dipper hypertension, which has not been reported previously. Moreover PLR more than 107 but not NLR was independent predictor of non-dipper status.

    Left Ventricular and Atrial Functions in Hypertrophic Cardiomyopathy Patients with Very High LVOT Gradient: A Speckle Tracking Echocardiographic Study
    (WILEY-BLACKWELL, 2014) ÇİNÇİN, AHMET ALTUĞ; Tigen, Kursat; Sunbul, Murat; Karaahmet, Tansu; Dundar, Cihan; Ozben, Beste; Guler, Ahmet; Cincin, Altug; Bulut, Mustafa; Sari, Ibrahim; Basaran, Yelda
    BackgroundDetermination of myocardial deformation (strain) by two-dimensional (2D) speckle tracking echocardiography (STE) is a new method for evaluating left ventricular (LV) regional function in patients with hypertrophic cardiomyopathy (HCM). The aim of this study was to assess LV and left atrial (LA) functions with 2DSTE in HCM patients and to investigate relation between strain analysis and LV outflow tract (LVOT) gradient. MethodsForty consecutive HCM patients (26 male, mean age: 47.715.2years), and 40 healthy volunteers (22 male, mean age: 46.611.2years) were included in the study. All subjects underwent a transthoracic echocardiography for evaluation of LV and LA functions with 2DSTE. The HCM patients were divided into 2 groups according to the presence of resting LVOT gradient >100mmHg. ResultsLeft ventricular global longitudinal strain (GLS), global radial strain (GRS), and global circumferential strain (GCS) were significantly lower in patients with HCM compared with controls (-20.3 +/- 3.6% vs. -24.1 +/- 3.4% P<0.001, 38.1 +/- 12.8% vs. 44.8 +/- 10.2% P=0.012, and -22.0 +/- 4.4% vs. -23.9 +/- 4.0% P=0.045, respectively). Although basal and apical rotation were similar between the groups, mid-rotation was significantly clockwise in HCM patients (-1.53 +/- 2.06 degrees vs. 0.05 +/- 1.7 degrees P<0.001). Both LA reservoir functions and LA conduit functions were significantly lower in HCM patients (21.6 +/- 9.1% vs. 39.4 +/- 10.6% P<0.001, and 10.5 +/- 4.3% vs. 15.7 +/- 5.3%, P<0.001). Fifteen patients had a resting LVOT gradient of >100mmHg and they had significantly decreased GLS, twist and untwist compared to the HCM patients with lower resting LVOT gradient (-18.7 +/- 2.3% vs. -21.2 +/- 3.9% P=0.016, 19.4 +/- 4.3 degrees vs. 23.5 +/- 7.4 degrees P=0.038 and -94.0 +/- 29.1 degrees/sec vs. -134.9 +/- 55.8 degrees/sec, 0.005, respectively). Although basal and apical rotation were similar between the 2 groups, mid-rotation was significantly clockwise in HCM patients with higher LVOT gradient (-2.52 +/- 1.76 degrees vs. -0.96 +/- 2.03 degrees, P=0.018). Correlation analysis revealed that LVOT peak velocity was associated with GLS (r=-0.358, P=0.023), LV mid-rotation (r=-0.366, P=0.024), and LV untwist (r=-0.401, P=0.013). ConclusionsLeft ventricular and LA functions are impaired in patients with HCM. 2DSTE is useful in determining patients with impaired myocardial mechanics. High LVOT gradient may be one of the responsible factors that trigger deterioration of LV longitudinal strain and twist mechanics in patients with HCM. Further studies are required to clarify the preliminary results of this study.

    Postoperative Atrial Fibrillation after Coronary Artery Bypass Grafting Surgery: A Two-dimensional Speckle Tracking Echocardiography Study
    (ELSEVIER SCIENCE INC, 2016) ÖZBEN SADIÇ, BESTE; Ozben, Beste; Akaslan, Dursun; Sunbul, Murat; Filinte, Deniz; Ak, Koray; Sari, Ibrahim; Tigen, Kursat; Basaran, Yelda
    Background Postoperative atrial fibrillation (POAF) may develop after coronary artery bypass grafting (CABG). The aim of the study was to explore the relationship between preoperative left atrial function and atrial fibrosis and POAF after CABG. Methods Forty-eight consecutive patients undergoing CABG (mean age: 61.6 +/- 8.9 years, 39 male) were included. All patients were in sinus rhythm during surgery. Patients were followed by continuous electrocardiography monitoring and daily electrocardiogram. Left atrial function was assessed by both conventional and speckle tracking echocardiography. Atrial fibrosis was determined by samples taken from right atrium. Results Postoperative atrial fibrillation was detected in 13 patients. Female sex and number of bypassed vessels were significantly higher and cardiopulmonary bypass time was significantly longer in patients with POAF. Left atrial volume index (LAVI) was significantly higher while left atrial reservoir strain was significantly lower in POAF patients. The percentage of patients with severe fibrosis was higher in the POAF group. Regression analysis revealed fibrosis and LAVI as independent predictors of POAF. Left atrial volume index >= 36 mL/m(2) predicted POAF with a sensitivity of 84.6% and specificity of 68.6% in our cohort. Conclusion Patients who developed POAF after CABG had more fibrosis, increased LAVI and lower left atrial reservoir strain. Preoperative echocardiography might be helpful in discriminating these patients.

    Effect of vitamin D deficiency and supplementation on myocardial deformation parameters and epicardial fat thickness in patients free of cardiovascular risk
    (SPRINGER, 2015) ÇİNÇİN, AHMET ALTUĞ; Sunbul, Murat; Bozbay, Mehmet; Mammadov, Ceyhun; Cincin, Altug; Atas, Halil; Ozsenel, Ekmel Burak; Sari, Ibrahim; Basaran, Yelda
    Vitamin D deficiency is associated with impaired myocardial deformation parameters and cardiovascular disease (CVD). Increased epicardial fat thickness (EFT) is also associated with increased risk of CVD. The aim of the study is to evaluate the effect of vitamin D deficiency and supplementation on myocardial deformation parameters and EFT. The study population consisted of 50 patients with vitamin D deficiency who were free of cardiovascular risk (mean age: 42.6 +/- A 8.9 years, 37 female). Patients were treated with oral administration of vitamin D3. Myocardial deformation parameters and EFT were evaluated before and after treatment of those patients. Vitamin D levels significantly increased after treatment (30.5 +/- A 10.5 vs. 9.9 +/- A 5.3 nmol/l, p < 0.001). There was no significant difference between conventional echocardiographic parameters before and after treatment. Baseline EFT was significantly higher than post-treatment measurements (35.2 +/- A 8.0 vs. 27.5 +/- A 5.6 mm, p < 0.001). Post-treatment myocardial deformation parameters were also significantly higher than baseline measurements. Baseline vitamin D levels correlated with baseline EFT and left ventricular global longitudinal strain (LV-GLS). Post-treatment vitamin D levels also correlated with post-treatment EFT, body mass index, and LV-GLS. Baseline vitamin D level was an independent predictor of baseline LV-GLS (p = 0.002). Patients with impaired LV-GLS had significantly lower vitamin D levels than patients with normal LV-GLS (6.6 +/- A 3.8 vs. 11.0 +/- A 5.3 nmol/l, p = 0.005). Baseline vitamin D level was also an independent predictor of baseline impaired LV-GLS (p = 0.010). Vitamin D supplementation has beneficial effects on myocardial deformation parameters and EFT. Moreover, baseline vitamin D levels are a predictor of impaired LV-GLS.
