    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.

    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.
