Abstract
OBJECTIVES Systemic sclerosis (SSc) is a chronic, inflammatory, and autoimmune connective tissue disease that is associated with vascular lesions, and fibrosis of the skin and visceral organs. Cardiac complications may occur as a secondary effect of SSc as a result of pulmonary arterial hypertension and interstitial lung disease. The objective of this study was to assess whether the pulmonary pulse transit time (pPTT) could serve as a diagnostic marker for pulmonary arterial alterations in patients with SSc, prior to development of pulmonary hypertension. METHODS Twenty-five SSc patients as a study group and 25 age- and sex-matched healthy volunteers for the control group were recruited to the study. Right ventricle function parameters, such as tricuspid annular plane systolic excursion (TAPSE), estimated pulmonary artery systolic pressure (ePASP), right ventricular dimensions, right ventricle fractional area changes, and myocardial perfusion index (MPI) were measured and calculated. Pulmonary pulse transit time was defined as the time interval between the R-wave peak in the ECG and the corresponding peak late systolic pulmonary vein flow velocity. RESULTS Right ventricle myocardial performance index (RVMPI) and eSPAP were significantly higher in the SSc group than the controls (p = 0.032, p = 0.012, respectively). Pulmonary pulse transit time and TAPSE was shorter in the patients with SSc (p = 0.006, p = 0.015, respectively). In correlation analysis, pPTT was inversely correlated with RVMPI (r = - 0.435, p = 0.003), eSPAP (r = - 0.434, p = 0.003), and disease duration (r = - 0.595, p = 0.003). Conversely, it positively correlated with TAPSE (r = 0.345, p = 0.022). CONCLUSION pPTT was found to be shorter in SSc patients. pPTT might serve as a surrogate marker of pulmonary hemodynamics in patients with SSc, even prior to the development of pulmonary hypertension.

Abstract
BACKGROUND The frequency of arrhythmic death developing without a structural cardiac disease is higher in women. Also, female sex is an independent risk factor regarding development of torsades de pointes. Several studies have been conducted on the physiological and therapeutic effects of sex hormones on the cardiac conduction system. AIM In this study we aim to examine the effect of hormonal changes, especially supraphysiological E2 level changes occurring during in vitro fertilisation treatment, on ventricular repolarisation parameters. METHODS The study included female patients aged between 23 and 39 years, who were administered controlled ovarian hyperstimulation treatment. Patients' electrocardiograms and blood samples were obtained and analysed before and after the ovarian hyperstimulation treatment. RESULTS Mean QTc intervals before ovarian hyperstimulation were 411.9 ± 23.7 ms. Measurements during oestradiol peak were calculated as 420.7 ± 23.3 ms, and the QTc interval increase was significant (p = 0.007). Corrected QT dispersion averages were not significant before or after hyperstimulation (53 ± 17 ms vs. 54.5 ± 18.2 ms, respectively, p > 0.05). Tp-e, J-T peak, and PR dispersion changes were not significant after the ovarian hyperstimulation therapy. CONCLUSIONS Supraphysiological oestradiol levels that occur during controlled ovarian hyperstimulation cause prolongation of QTc intervals, but not to a pathological level. Although this prolongation is not significant in healthy individuals, it might increase ventricular arrhythmia risk in patients with congenital long QT syndrome and in patients taking medication that prolongs QT.

Abstract
BACKGROUND The effects of gender difference on cardiac electrophysiology have been well studied. In this study, we aimed to evaluate the effects of estradiol and progesteron changes occuring in physiological menstrual cycle on ventricular premature beats (VPBs) and cardiac repolarization parameters. METHODS Women of reproductive age with VPBs were included into the study group and healthy women were recruited as the control group. During the menstruation period, a 12-lead electrocardiography, blood samples, and 24-hour rhythm Holter were applied to the study group. Similarly, all tests were repeated in the estimated ovulation period (12-14 days before menstruation) by all cases. RESULTS The study group consisted of 20 women patients with VPB, and the control group of 18 healthy women. While the number of VPB in the menstruation period was 210 beats/day (interquartile range [IQR]: 1,144), it decreased to 86 beats/day (IQR: 251) in the ovulation period with statistical significance (P < 0.05). Average heart rate in the menstruation period was 81.4 ± 10 beats/min and it significantly increased to 84.6 ± 8 beats/min in the ovulation period (P < 0.05). There were no differences in cardiac repolarization parameters in both menstruation and ovulation periods between the study and control groups. Comparing the menstruation and the ovulation periods, J-Tpeak interval, which reflects early repolarization, was shorter in the ovulation period (193 ± 27.7 ms and 201.1 ± 28.6 ms, respectively; P < 0.05). Other repolarization parameters did not show any significant difference. CONCLUSION VPB frequency decreases with estradiol peak in the ovulation period. This suggests that estrogen may have protective effects against ventricular arrhythmias.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is associated with increased risk of malignant ventricular arrhythmias. Cardiac electrical inhomogeneity may be the leading cause of the increased arrhythmic risk in patients with T2DM. The peak and the end of the T wave (Tp-e) interval and associated Tp-e/QT ratio are promising measures of ventricular repolarization indicating transmural dispersion of repolarization. The aim of this study was to assess ventricular repolarization in patients with T2DM by using Tp-e interval, Tp-e/QT ratio and Tp-e/corrected QT interval (QTc) ratio. METHODS Forty-three patients with T2DM and 43 healthy control subjects, matched by gender and age, were studied. All participants underwent electrocardiography (ECG) recording. PR, RR and QT intervals represents the ECG intervals. These are not abbreviations. In all literature these ECG intervals are written like in this text. Tp-e intervals were measured from 12-lead ECG. Rate QTc was calculated by using the Bazett's formula. Tp-e/QT ratio and Tp-e/QTc ratio were also calculated. RESULTS Mean Tp-e interval was significantly prolonged in patients with T2DM compared to controls (79.4±10.3, 66.4±8.1 ms, respectively; P<0.001). We also found significantly higher values of Tp-e/QT ratio and Tp-e/QTc ratio in patients with diabetes than controls (0.21±0.03, 0.17±0.02 and 0.19±0.02, 0.16±0.02, respectively; P<0.001). There was no difference in terms of the other ECG parameters between the groups. CONCLUSION Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio were prolonged in patients with T2DM. We concluded that T2DM leads to augmentation of transmural dispersion of repolarization suggesting increased risk for ventricular arrhythmogenesis.

Abstract
Although the combined use of hydralazine and isosorbide dinitrate confers important clinical benefits in patients with heart failure, the underlying mechanism of action is still controversial. We used two models of nitroso-redox imbalance, neuronal NO synthase-deficient (NOS1(-/-)) mice and spontaneously hypertensive heart failure rats, to test the hypothesis that hydralazine (HYD) alone or in combination with nitroglycerin (NTG) or isosorbide dinitrate restores Ca(2+) cycling and contractile performance and controls superoxide production in isolated cardiomyocytes. The response to increased pacing frequency was depressed in NOS1(-/-) compared with wild type myocytes. Both sarcomere length shortening and intracellular Ca(2+) transient (Δ[Ca(2+)]i) responses in NOS1(-/-) cardiomyocytes were augmented by HYD in a dose-dependent manner. NTG alone did not affect myocyte shortening but reduced Δ[Ca(2+)]i across the range of pacing frequencies and increased myofilament Ca(2+) sensitivity thereby enhancing contractile efficiency. Similar results were seen in failing myocytes from the heart failure rat model. HYD alone or in combination with NTG reduced sarcoplasmic reticulum (SR) leak, improved SR Ca(2+) reuptake, and restored SR Ca(2+) content. HYD and NTG at low concentrations (1 μm), scavenged superoxide in isolated cardiomyocytes, whereas in cardiac homogenates, NTG inhibited xanthine oxidoreductase activity and scavenged NADPH oxidase-dependent superoxide more efficiently than HYD. Together, these results revealed that by reducing SR Ca(2+) leak, HYD improves Ca(2+) cycling and contractility impaired by nitroso-redox imbalance, and NTG enhanced contractile efficiency, restoring cardiac excitation-contraction coupling.

Abstract
INTRODUCTION Pseudothrombocytopenia (PTCP), caused by platelet (PLT) aggregation, is usually associated with ethylenediaminetetraacetic acid (EDTA)-dependent antibodies and cold aggluti-nins against PLT antigens. The aim of this study was to identify the PTCP and discover the most practical method to distinguish it from real thrombocytopenia. METHODS This study included 85 patients without hemorrhagic abnormalities and suspected PTCP. Blood samples containing EDTA, citrate and EDTA-kanamycin (KN) were analyzed at room temperature and 37°C. RESULTS PTCP was detected in 24 of 85 patients. In 23 of 24 patients, EDTA-dependent pseudothrombocytopenia (EDTA-PTCP) was detected; 5 of whom had also the cold agglutinin-dependent PTCP. In only 1 of 24 patients, the cold agglu-tinin-dependent PTCP was found. In this study, no significant difference was observed in leukocyte counts comparing EDTA and citrate blood samples in cases with EDTA-PTCP. CONCLUSION In clinical laboratories, a significant portion of the cases with low PLT counts was attributable to EDTA-PTCP and, therefore, did not require treatment. Even if these cases can be detected by bringing the blood samples containing EDTA to 37°C or by adding KN to blood samples containing EDTA, the use of blood samples containing citrate taken for erythrocyte sedimentation rate analysis is a more practical priority method.

Abstract
OBJECTIVE The objective of this study was to compare frequently used cardiovascular risk scores in predicting the presence of coronary artery disease (CAD) and 3-vessel disease. METHODS AND RESULTS In 350 consecutive patients (218 men and 132 women) who underwent coronary angiography, the cardiovascular risk level was determined using the Framingham Risk Score (FRS), the Modified Framingham Risk Score (MFRS), the Prospective Cardiovascular Münster (PROCAM) score, and the Systematic Coronary Risk Evaluation (SCORE). The area under the curve for receiver operating characteristic curves showed that FRS had more predictive value than the other scores for CAD (area under curve, 0.76, P < or = 0.001), but all scores had good specificity and positive predictive value. For 3-vessel disease, the FRS had better predictive value than the other scores (area under curve, 0.74, P < or = 0.001), but all scores had good specificity and negative predictive value. CONCLUSION The risk scores (FRS, MFRS, PROCAM, and SCORE) may predict the presence and severity of coronary atherosclerosis.The FRS had better predictive value than the other scores.

Abstract
BACKGROUND Prolongation of the peak and the end of T wave (Tp-e) has been reported to be associated with ventricular arrhythmias. Tp-e/QT ratio and Tp-e/QTc ratio are used as an index of ventricular arrhythmogenesis. An increased incidence of ventricular arrhythmias has been reported in patients with obstructive sleep apnea (OSA). The aim of this study was to assess ventricular repolarization in patients with OSA by using Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio. METHODS We have studied 72 patients who underwent overnight polysomnography (PSG) between the years 2010-2011 at our institution. Patients with moderate and severe OSA (23 patients; mean age: 45±10), according to the apnea-hypopnea index, constituted the study group. Patients with normal PSG (23 patients; mean age: 42±11) were used as the control group. In all patients, Tp-e interval, Tp-e/QT ratio, Tp-e/QTc ratio, as well as some other electrocardiogram intervals were measured. Independent samples t-tests were used for comparison of continuous and categorical variables and correlations were calculated by Spearman rank correlation. RESULTS Although QT and QTc intervals were not different between the groups, mean Tp-e interval (81.6±11.1 msn; 63.9±7.3 msn; respectively; P < 0.001), Tp-e/QT ratio (0.21±0.03; 0.17±0.02; respectively; P < 0.001), and Tp-e/QTc ratio (0.20±0.03; 0.16±0.02; respectively; P < 0.001) were prolonged in the study group compared to the control group. Correlation analysis showed a significant positive correlation between the presence of moderate and severe OSA and Tp-e interval (r = 0.72; P < 0.001), Tpe/QT ratio (r = 0.70; P < 0.001), and Tp-e/QTc ratio (r = 0.70; P < 0.001). CONCLUSIONS Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio are prolonged in patients with moderate and severe OSA patients. There is a positive correlation between the presence of OSA and Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio.

Abstract
AIM To assess the value of aortic flow propagation velocity (Vp) in detecting hypertensive patients with coronary risk. METHODS The study included 120 patients with hypertension. According to the 10-year risk of coronary heart disease the patients were categorized in the three groups: 10-year risk < 10% (I),10 - year risk=%10 - 20 (II), and 10-year risk > 20% (III). The aortic flow propagation velocity (Vp) was measured from descending aorta with color M-mode echoardiography. The slope of the first aliasing contour was accepted as Vp. It was compared with Framingham coronary risk score, carotid intima media thickness and high sensitive C-reactive protein. Twelve patients were excluded from the study due to poor acoustic window. RESULTS The Vp was significantly lower (p<0.001), carotid intima media thickness and high sensitive C-reactive protein was significantly higher in group III (p=0.002 and p=0.014). The area under ROC curve of Vp, carotid intima media thickness and high sensitive C-reactive protein were 0.890, 0,700 and 0.664, respectively. There was a significant inverse relation between Vp and carotid intima media thickness (r=-0.37; p<0.001). CONCLUSIONS The aortic flow propagation velocity is a simple, feasible and reproducible marker of atherosoclerosis with an acceptable sensitivity and specificity. There is a need for longitudinal prospective studies to use it routinely.

Abstract
BACKGROUND We wanted to compare the values of clinical risk assessments and scoring systems for predicting three-vessel diseases and culprit lesions by coronary angiography in patients with unstable angina pectoris (UAP), or non-ST segment elevation myocardial infarction (NSTEMI). METHODS A total of 154 consecutive patients, (42 [27.3%] female, and 112 [72.7%] male, mean age: 63.0 ± 12.7 years) with UAP/NSTEMI were enrolled. Rizik and Braunwald classification, ACC/AHA risk assessment system, TIMI, GUSTO, GRACE and PURSUIT risk scores were determined, and the ROC curve was marked in accordance with the presence of three-vessel disease and culprit lesion. RESULTS In patients with NSTEMI, the rates of three-vessel disease and culprit lesion were demonstrated to be higher. With respect to the presence of three-vessel disease, only the ACC/AHA risk assessment was manifested to have a predictive value. All risk scoring systems were demonstrated to bear predictive values with different sensitivity and specificity. The TIMI and GRACE risk scores were discovered to have higher predictive values. The presence of culprit lesions could not be predicted by any of the risk assessment or scoring systems. CONCLUSIONS Among risk assessment systems, only the ACC/AHA system can be used to predict three-vessel disease. It is possible to use all risk scoring systems for the same purpose. The predictive values of the TIMI and GRACE risk scores are higher. The culprit lesions cannot be predicted by any of the risk assessment or scoring systems. The use of cardiac enzymes seems more appropriate with very low sensitivity and specificity.

Abstract
AIM To simplify proximal isovelocity surface area (PISA) method for mitral valve area (MVA) calculation that does not necessitate the usage of a calculator and angle correction, and to compare values estimated using this novel method with the values obtained by the conventional PISA, planimetry and pressure half-time (PHT) methods. METHODS We evaluated patients with a wide range of mitral stenosis (MS) severity. The MVA was measured by the methods of PHT (MVA PHT), planimetry (MVApl), conventional PISA (MVAC-PISA) and the novel method of simple PISA (MVAS-PISA). Application of simple PISA was performed subsequently by division of the peak mitral inflow velocity by four; measurement of the radius by adjusting the aliasing velocity to this value; square of the radius gives the MVAS-PISA. RESULTS Twenty patients were enrolled in the study. Peak and mean pressure gradients of patients were 20 ± 6 mmHg and 10 ± 4 mmHg, respectively. The average values of MVApl, MVAPHT, MVAC-PISA, and MVA S-PISA were 1,54 ± 0,41, 1,65 ± 0,40, 1,58 ± 0,42, 1,57 ± 0,44 cm2, respectively. MVAS-PISA had a strong correlation with the MVAC-PISA, MVApl and MVAPHT . Furthermore, there was no significant difference between simple PISA and the other methods. The agreement between planimetry and simple PISA methods for detecting severe mitral stenosis (MVA <1.5 cm2) determined by ROC analysis was very good with a sensitivity and specificity of 100 % and 92%, respectively. CONCLUSIONS Simple PISA is a user friendly method which does not take time and gives simple and correct results. If the diagnostic power of the technique is proven by more comprehensive studies, it can supersede the conventional PISA method.

Abstract
AIM To investigate elastic characteristics of the aorta in patients with epilepsy. METHODS Seventy five patients with a diagnosis of epilepsy through clinical and EEG findings and age and sex matched, 50 healthy controls were included. Systolic and diastolic blood pressures plus systolic and diastolic diameter of the aortic root was measured. Aortic strain (AS) and aortic distensibility (AD) and aortic distensibility index (BSI) were calculated. RESULTS The average age of the epilepsy group was 23.8.8 +/- 8.2 years, and of the control group it was 24.1 +/- 6.2 years (p > 0.05). AS and AD were lower in the epileptic group while the aortic stiffness index was higher (10.4 +/- 4.2 vs 16.9 +/- 0.2, p: 0.001, for AS; 8.7 +/- 4.0 vs 17.2 +/- 0.1, p: 0.001, for AD and 20.1 +/- 0.1 vs 3.5 +/- 1.2, p: 0.001 for BSI). CONCLUSION Elastic characteristics of the aorta change in epileptic patients, with a decrease of the distensibility of the aorta and an increase of the stiffness. After this preliminary study, new controlled studies are needed.
