Purpose: The aim of this study is to investigate the relationship between the criteria comprising metabolic syndrome (MS) and neutrophil–lymphocyte ratio (NLR), a simple and reliable indicator of inflammation. Method: Seventy patients with MS and 71 age- and sex-matched control participants were included. Patients were classified into 3 groups based on the number of MS criteria: group 1 (with 3 criteria), group 2 (with 4 criteria), and group 3 (with 5 criteria). The NLR was calculated from complete blood count. Results: Patients with MS had significantly higher NLR compared to the control group. Moreover, the group 3 patients had higher NLR than those in groups 2 and 1 (P = .008 and P = .078, respectively), whereas there was no difference between the patients meeting 3 and 4 MS criteria (P = .320). Besides, NLR increased as the severity of MS increased (r = .586, P < .001). The cutoff level for NLR with optimal sensitivity and specificity was calculated as 1.84. Serum glucose and high-sensitive C-reactive protein level were found to be independent predictors of an NLR value greater than 1.84. Conclusion: The present study indicated a significant correlation between the criteria of MS and inflammation on the basis of NLR. Furthermore, there an increase in NLR as the severity of MS increases.

Objectives: The aim of the present study was to assess the association between the level of pentraxin-3 (PTX-3) and the severity of metabolic syndrome (MS). Subjects and Method: One hundred and two patients with MS and 101 consecutive age- and sex-matched control subjects were included in the study. The MS patients were classified into three groups based on the number of MS criteria, i.e. group 1: patients with 3 MS criteria, group 2: patients with 4 MS criteria, and group 3: patients with 5 MS criteria. Serum PTX-3 and high-sensitivity C-reactive protein (hs-CRP) levels were measured. Results: Group 1 had higher PTX-3 levels compared to the control group (0.58 ± 0.11 ng/ml vs. 0.36 ± 0.15 ng/ml, p < 0.001). PTX-3 levels were higher in group 3 than in both group 1 (0.90 ± 0.06 ng/ml vs. 0.58 ± 0.11 ng/ml, p < 0.001) and group 2 (0.90 ± 0.06 ng/ml vs. 0.63 ± 0.12 ng/ml, p < 0.001). Group 3, however, had higher hs-CRP levels than both group 1 (1.89 ± 0.45 mg/dl vs. 1.40 ± 0.44 mg/dl, p = 0.007) and group 2 (1.89 ± 0.45 mg/dl vs. 1.47 ± 0.58 mg/dl, p = 0.01). The control group had lower hs-CRP levels than group 1 (0.81 ± 0.47 mg/dl vs. 1.40 ± 0.44 mg/dl, p < 0.001) and group 2 (0.81 ± 0.47 mg/dl vs. 1.47 ± 0.58 mg/dl, p < 0.001). Serum PTX-3 levels correlated with serum hs-CRP levels (r = 0.49, p < 0.001). Conclusions: PTX-3, a novel inflammatory marker, was found to be associated with the severity of MS.

Abstract Background. Ventricular dyssynchrony is an co-determinant of progression and exacerbation of heart failure (HF). The co-existence of ventricular dyssynchrony with hypertension (HT) and HF were shown, however there is no data regarding the effect of circadian rhythm of blood pressure (BP) on ventricular synchrony. Therefore, we aimed to study the left ventricular synchrony in dipper and non-dipper normotensive and hypertensive participants. Methods. Participants (n = 142) were categorized into four groups as “Normotensive-Dipper” (NT-D) (n = 40), “Normotensive-Non-dipper” (NT-ND) (n = 30), “Hypertensive-Dipper” (HT-D) (n = 38) and “Hypertensive-Non-dipper” (HT-ND) (n = 34). Left ventricular dyssynchrony was investigated by color-coded tissue Doppler imaging. Results. Non-dippers had higher 24-h and night-time BP both in normotensives and hypertensives. The incidence of ventricular dyssynchrony (a Ts-SD-12 > 34.4 ms) was higher in the hypertensive group (47.2% vs 24.3%, p = 0.005). The frequency of ventricular dyssynchrony was higher in the HT-ND group than the HT-D group (58.8% vs 36.8%, p = 0.05); however, the frequency of ventricular dyssynchrony was similar among the normotensives (26.7% vs 22.5%, p = 0.45). Ts-SD-12 and Ts-12 were higher in NT-ND group than the NT-D group. Conclusions. Non-dipping BP pattern was associated with impaired left ventricular contraction synchrony in both normotensive and hypertensive participants, which may be related with short- and long-term effects of HT on myocardium.

OBJECTIVE Electrocardiography (ECG) may be a practical guiding tool for prognostic infarct sizing in ST elevation acute myocardial infarction (STEAMI). In this study, we sought to find a relation between the infarct size and the change in the QRS axis after thrombolytic therapy. MATERIALS AND METHODS Patients with STEAMI who received thrombolytic therapy were selected retrospectively. The mean QRS axes of two ECGs (before and 90 minutes after thrombolytic therapy) were calculated. Creatinine kinase MB (CKMB) was used as the marker of infarct size. RESULTS We did not detect any correlation between infarct size and change in the QRS axis with respect to any myocardial infarction MI localizations (p=0.80). However, in the isolated inferior MI group, there was a good correlation between CKMB and change in the QRS axis (r=-0.52 p=0.049). CONCLUSION The change in the QRS axis is rarely emphasized, providing a practical and promising tool for evaluating both the efficiency of the thrombolytic therapy and prognostic infarct sizing.

Ailesel hiperkolesterolemi ile birlikte diffüz asendan aorta ve sol ana koroner arter tutulumu: Olgu Sunumu

Eyup Buyukkaya; Şule Büyükkaya; Esra Karakas; Bilge Bülbül Şen; Mehmet Fatih Karakas

Familial hypercholesterolemia (FH) is an inherited genetic disorder leading to increased plasma LDL levels due to defects in LDL-cholesterol metabolism. Atherosclerosis occurs early due to the high serum lipid levels and inability to eliminate LDL-cholesterol from circulation. This results in coronary artery disease and atherosclerotic aorta at early age. Atheromatous alterations in aortic root lead to coronary osteal lesions and irregularities in the inner aortic wall. We present an FH case with extensive involvement of ascending aorta with coronary ostial lesion. Keywords: Familial hypercholesterolemia, left main coronary artery
