Abstract
OBJECTIVE This study aimed at the assessment of the clinical approach to atrial fibrillation (AF) in the older population and the consistency with the guidelines based on the records of the multicenter, prospective AFTER (Atrial Fibrillation in Turkey: Epidemiologic Registry) study. PATIENTS AND METHODS 2242 consecutive patients admitted to the Cardiology Outpatient Clinics of 17 different tertiary Health Care Centers with at least one AF attack determined on electrocardiographic examination, were included in the study. Among the patients included in the study, 631 individuals aged 75 years and older were analyzed. RESULTS The mean age of the patients was determined as 80.3±4.2 years. The most frequent type of AF in geriatric population was the persistent-permanent type with a percentage of 88%. 60% of the patients with AF were female. Hypertension was the most common co-morbidity in patients with AF (76%). While in 16% of patients a history of stroke, transient ischemic attack or systemic thromboembolism was present, a history of bleeding was present in 14% of the patients. 37% of the patients were on warfarin treatment and 60% of the patients were on aspirin treatment. In 38% of the patients who were on oral anticoagulant treatment, INR level was in the effective range. CONCLUSIONS The rate of anticoagulant use in the elderly with AF was 37% and considering the reason of this situation was the medication not being prescribed by the physician, one should pay more attention particularly in the field of treatment.

Abstract
This study was aimed to investigate sensitivity and specificity of QT dispersion (QTd) as a predictor of hypertensive response to peak exercise stress testing (EST). Fifty-nine patients were divided in to two groups (32 patients with exaggerated blood pressure response (EBPR) to EST group and 27 patients for normotensive group) and the EST was monitored. The QTd and corrected QT (QTc) intervals were still found to be significant predictors of EBPR (P < 0.05). In receiver operating characteristic (ROC) analysis, a level of QTd ≥ 40 predicted EBPR with 84% sensitivity and 74% specificity. According to the present data, QTd might be an important predictive marker for EBPR.

Abstract
OBJECTIVE Atrial fibrillation (AF) is an important health problem in Turkey. However, no prospective, multicenter, large trial reflecting national data has been published so far. Therefore, the aim of this study was to follow, analyze and evaluate patients with AF in a large multicenter nation-wide trial. METHODS Two thousand three hundred consecutive patients with AF in their electrocardiogram, reflecting all the population of seven geographical regions of Turkey will be included in the study. The patients will be followed up for two years and death, transient ischemic attack, stroke, systemic thromboembolism, major bleeding, hospitalization will be recorded as the primary end-point. RESULTS Will be available at the end of the study; preliminary results will be due December 2012. CONCLUSION General risk profile of patients with AF, frequency of anticoagulation, frequency of effective treatment and risks of bleeding will be evaluated according to the current guidelines. Major adverse events and their independent predictors will be determined.

Abstract
AIM We tried to understand whether or not there was a gender difference in coronary artery interventions in coronary heart disease (CHD) cases in the present study. METHODS The study was performed in two phases. The first phase was performed at the Internal Medicine Polyclinic of the Dumlupinar University between August 2005 and March 2007. CHD was diagnosed either angiographically or with history of coronary artery stenting (CAS) and/or coronary artery bypass graft (CABG) surgery. The second phase was performed at the Internal Medicine Polyclinic of the Mustafa Kemal University between March 2007 and April 2012. During the second phase, the CHD patients with CAS and/or CABG surgery were detected and divided into two groups according to the gender. RESULTS Mean age and prevalence of CHD were similar in both genders (p>0.05 for both) in the first phase. Smoking was higher in males with CHD, in 30 cases (54.5%) of males versus six (9.6%) cases of females (p < 0.001), as well as chronic obstructive pulmonary disease (COPD), in ten (18.1%) cases of males versus four (6.4%) cases of females (p < 0.05). Although the body mass index (BMI) and white coat hypertension (WCH) were insignificantly higher (p>0.05 for both), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) were significantly higher in females with CHD (p= 0.008 and p= 0.002, respectively). Hypertension (HT) and diabetes mellitus (DM) were higher in females with CHD, too (p < 0.001 and p < 0.05, respectively). On the other hand, CAS and/or CABG surgery were significantly higher in male CHD cases (21.8% versus 1.6%, p less 0.001). Parallel to the first phase cases, majority of CAS and/or CABG surgery cases were males in the second phase cases too (90.2% versus 9.7%, p less 0.001). CONCLUSION As some components of the metabolic syndrome, smoking and COPD were higher in males whereas BMI, WCH, LDL-C, TG, HT and DM were higher in females. Despite similar prevalences of CHD in both sexes, CAS and/or CABG surgery were significantly higher in males probably due to fear of loss of power required for their dominant roles in life and sexuality.

Abstract
In this study, possible oxidative stress, biomarkers, and histopathological alterations were investigated in common carp (Cyprinus carpio, L., 1758) that were exposed to various phosalone concentrations in vivo. Fish were exposed to 0.15, 0.3, and 0.6 mg/L phosalone concentrations in a semistatic regime for 14 d. Biomarkers, including Na(+), K(+)-ATPase, reduced glutathione (GSH), thiobarbituric acid-reactive substances (TBARS), and histopathological changes, were determined in gills, liver, and kidney tissues of fish. Sublethal phosalone concentrations produced lipid peroxidation and impairment in the antioxidant defense system by increasing reactive oxygen species (ROS) production. While GSH increased in all groups at d 7 compared to control, GSH fell significantly at medium and high doses at d 14. Reduced GSH levels were diminished in all tissues and a significant induction in lipid peroxidation (TBARS) was observed. Na(+),K(+)-ATPase enzyme activity was significantly inhibited especially in gills. No histopathological effects were observed in the control group. Lamellar aneurysm, lamellar fusion, hyperplasia, epithelial lifting, and hemorrhages were observed in gill tissues exposed to phosalone. Histopathological effects in the liver tissues of fish exposed to phosalone were characterized by cytoplasmic vacuolation, congestion, hypertrophy, and nuclear degeneration. Hypertrophy, tubule degeneration, mononuclear cell infiltration, and dilation of glomerular capillaries were noted in kidney tissues exposed to phosalone. The results indicate that phosalone exposure adversely affected the health of the fish, attributable to oxidative stress.

Abstract
BACKGROUND AND OBJECTIVE In this study, we aimed to investigate the factors affecting the survival of patients with malignant pleural mesothelioma (MPM) according to their treatment regimens, including best supportive care (BSC), chemotherapy, surgical group and multimodality (MM) therapy. PATIENTS A retrospective analysis was performed on clinical data and treatment outcomes of 400 patients registered in our hospital with MPM between January 1989 and April 2010. RESULTS Mean age (p < 0.001), presence of asbestos exposure (p = 0.0014), presence of smoking history (p < 0.001), Karnofsky performance status (p < 0.001), histological subtype (p = 0.034) and stage (p < 0.001) variables were found to be significantly different among the four treatment regimens. Mean survival time of all patients was 12.32 months. Mean survival time 10.5 months for the BSC group, 15.7 for the surgical group, 16.02 for the chemotherapy group, and 26.55 for the MM group. There were significant differences in mean survival time among the four treatment regimens. In addition, a significant difference was found in survival time between the two chemotherapy groups (p = 0.032). Mean survival time for cisplatin + gemcitabine was found to be 14.49 months and for cisplatin + pemetrexed, 18.34 months. CONCLUSIONS The MM group had better survival rates than the other groups. The new chemotherapy combination, cisplatin + pemetrexed, can be helpful in improving survival time.

Abstract
BACKGROUND Platelets are important in the pathogenesis of atherosclerotic complications. Higher mean platelet volume (MPV) levels are related to greater in vitro aggregation, and have been identified as an independent risk factor for myocardial infarction, and for death or recurrent vascular events. AIM To determine the relationship between MPV and the coronary collateral circulation. METHODS The sample consisted of 96 patients with coronary artery disease, and patients were separated into two groups according to their poorly developed or well-developed collateral circulation. Coronary collateral vessels were analyzed according to the Cohen and Rentrop grading system of 0-3. RESULTS All analyses were conducted using SPSS 11.5 (SPSS for Windows 11.5, Chicago, IL, USA). Continuous variables were expressed as mean ± SD, and categorical variables were expressed as percentages. Comparison of categorical and continuous variables between the group with well-developed coronary collateral vessels and the group with poorly developed vessels was performed using the chi-squared test and independent samples t-test, respectively. Platelet count and MPV values were similar between the two groups. CONCLUSIONS Our study found that MPV levels are not related to coronary collateral circulation.

Abstract
Purpose: The most important complication encountered in patients with b-thalassaemia major is degenerative fibrosis developing as a result of iron accumulation in myocardial tissue. Dysfunction pursues this accumulation. Recently, presence of fragmented QRS (fQRS) in ECG has been regarded as a predictor of myocardial fibrosis. We aimed in our study to investigate the frequency with which fQRS develops in patients with b-thalassaemia major and to disclose the correlation between fQRS frequency and Doppler-derived indices.
Methods: The patients with b-thalassaemia major (n=66; mean age: 23±6 years) and healthy controls (n=30; mean age: 23±4 years) were included. fQRS pattern was described as presence of RSR’ manifested as existence of additional R wave and notching in either R or S waves in ECG recordings. 2D, M-mode, conventional Doppler, tissue Doppler echocardiography parameters were assessed. Mean serum ferritin levels over past 5 years were also calculated.
Results: When compared to those in control group, fQRS was more frequent in b-thalassaemia major group, indicating statistical significance (p = 0.001). While E/Em and ferritin level exhibited statistically significant increase in thalassaemia patients with fQRS (p < 0.05), the mean Em and Sm values were found to be significantly low (p < 0.05).
Conclusions: fQRS was frequently observed in the patients with b-thalassaemia major, which was of statistical significance. Tissue Doppler-derived diastolic and systolic indices in thalassaemia cases with fQRS showed statistically significant impairment compared to those without fQRS. In conclusion, fQRS may represent a novel noninvasive marker for cardiac involvement in patients with b-thalassaemia major.

Abstract
Background: Pseudoexfoliation syndrome (PEX) is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation. Aims: The purpose of this study is to determine whether an association exists between ocular pseudoexfoliation and coronary artery disease, aortic aneurysms and peripheric vascular disease. Patients and Methods: 490 patients who underwent coronary angiography (CAG) at Kosuyolu Cardiovascula Research and Training Hospital were included in the study. Patients were evaluated for conventional risk factors such as age, sex, family history, hypertension, diabetes, dislipidemia and smoking. Detailed eye examinations including evaluation of lens were done in all patients. The presence of PEX material in the anterior segment was best appreciated by slit lamp after pupillary dilation. The patients were divided into two groups according to the presence of PEX, and compared for the presence of CAD and other risk factors. Results: CAD was present in 387 patients. 103 patients had normal coronary angiography. 20 (5.2 %) of CAD patients and 4 (3.9%) of normal CAG patients were found to have PEX (p>0.05). There was no significant relationship between CAD and the presence of PEX (p>0.05). When patients were grouped according to the presence of PEX, only age was significantly different between the two groups (r: 0.25, p<0.001). Conclusion: There is no significant relationship between the presence of PEX and CAD. Further studies in larger scales with elderly population may be more valuable.

Abstract
OBJECTIVES Interatrial duration is defined as prolonged p wave on electrocardiogram. p waves with a negative terminal phase recorded in V1 enclosing an area of one small square on the electrocardiogram is significantly and strongly correlated with interatrial duration. The aim of study was to investigate whether interatrial duration with p terminal force can be used as reflection of echocardiographic severity of mitral regurgitation. MATERIALS AND METHODS Sixty two consecutive patients with mitral regurgitation. were prospectively studied. Age/gender matched 57 subjects who had normal mitral structure and did not have mitral regurgitation. Patients with mitral regurgitation referred to a single cardiac center for echocardiography and who met the entry criteria documented moderate or severe mitral regurgitation with sinus were included. The interatrial duration was defined on the routine 12-lead electrocardiogram (50 mm/s, 10 mm/mV) using the greatest duration of p waves from D2, D3, AVF and V1. RESULTS There was a positive correlation between interatrial duration (>/= 110 ms) and effective regurgitant orifice (r = 0.3, p < 0.001). However, left atrial diameter and brain natriuretic peptide were significantly higher in cases with mitral regurgitation. There was also strong correlation between interatrial duration (>/= 110 ms) and p terminal force and left atrial diameter. ROC analysis revealed that interatrial duration of > 110 msec. could predict of severe mitral regurgitation with 88% sensitivity and 100% specificity. CONCLUSIONS Severe mitral regurgitation, left atrial diameter was correlated with p terminal force and interatrial duration. Significant interatrial duration (>/= 110 ms) and p terminal force might be considered as novel indicators of severe mitral regurgitation.

Abstract
OBJECTIVES Neurally mediated syncope is defined as a transient loss of blood flow to the brain, resulting in vasodilatation, bradycardia, or both. The pathophysiologic mechanisms of neurally mediated syncope are not clear. In this study, we investigated carotid artery elasticity parameters in patients with neurally mediated syncope. METHODS The study was conducted on 41 patients who were examined by the tilt table test. Group 1 constituted of 21 patients who had a positive response to the tilt table test. Clinical and hemodynamic parameters were compared with patients in a negative tilt table test group (group 2). The systolic and diastolic diameters of the carotid arteries, carotid distensibility, carotid strain, carotid stiffness index, and carotid elastic modulus of the left carotid arteries were calculated by a high-resolution ultrasound device. RESULTS No differences in hemodynamic variables or clinical parameters were detected between the groups. Carotid distensibility (mean ± SD, 1.6 ± 0.6 versus 2.2 ± 0.8 cm(2) × dyne(-1) × 10(-6); P = .044) and strain (6.8% ± 1.7% versus 8.2% ± 1.9%; P = .026) were lower in group 1 than in group 2. The carotid elastic modulus (0.88 ± 0.33 versus 0.74 ± 0.25 cm(2) × dyne(-1) × 10(-6); P = .002) and stiffness index (6.7 ± 0.4 versus 6.2 ± 0.5; P = .038) were higher in group 1. CONCLUSIONS In this study, we concluded that elastic properties of the carotid artery are impaired in patients with neurally mediated syncope. This finding suggests that impaired carotid arterial elasticity may be a factor in the pathophysiologic mechanisms of neurally mediated syncope.

Abstract
OBJECTIVE The aim of this study is to investigate the relationship between serum thyroid hormone levels that are within the normal range and the presence and severity of coronary artery disease (CAD) in patients referred for coronary angiography. METHODS In this observational study, we enrolled 119 consecutive patients (77 men, mean age 60.7±13.8 years) who underwent coronary angiography. Blood samples were tested for thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) concentrations. Additionally, risk factors, clinical characteristics and angiographic results were obtained. The patients were separated into two groups according to the Gensini score as those with mild or severe atherosclerosis. Statistical analysis was performed using the Chi-square, Mann-Whitney U, correlation and logistic regression tests, and ROC analysis. RESULTS FT3 levels were significantly lower in subjects with CAD (4.0±0.7 vs. 4.6±0.6 pmol/L; p<0.001). Moreover, lower FT3 levels were found in patients with severe atherosclerosis (3.9±0.7 vs. 4.5±0.6 pmol/L; p<0.001). Logistic regression analysis demonstrated that the lower FT3 levels were associated with the presence (OR =0.266, 95% CI: 0.097-0.731, p=0.01) and severity (OR=0.238, 95% CI:0.083-0.685, p=0.008) of CAD. In the ROC analysis, a level of FT3 ≤4.2 pmol/L was found to predict the presence of CAD with 69% sensitivity and 71% specificity (AUC:0.744, 95% CI:0.653-0.834, p<0.001); and the severity of CAD with 75% sensitivity and 67% specificity (AUC:0.733, 95% CI:0.642-0.824, p<0.001). CONCLUSIONS FT3 levels within the normal range were inversely correlated with the presence and severity of CAD. Moreover, lower FT3 concentrations were correlated with the Gensini score and independently predicted the presence and severity of CAD. Thus, the FT3 levels may be used as the indicator of increased risk for CAD.

Abstract
AIM to understand the role and significance of WCH in definition of the metabolic syndrome. METHODS the study was performed in the Internal Medicine Polyclinic of the Dumlupinar University between August 2005 and March 2007. We took consecutive patients at and above the age of 20 years. Their medical histories including smoking habit, DM, dyslipidemia, and already used medications were learnt, and a routine check up procedure including fasting plasma glucose (FPG), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and an electrocardiography was performed. Comparison of proportions was used as the method of statistical analysis. RESULTS the study included 1,068 cases. Prevalences of excess weight increased from the third (28.7%) up to the seventh decades (87.0%), gradually (p<0.05 nearly in all steps), and then decreased in the eighth (78.5%, p<0.05) decade of life. The most significant increase was seen during the passage from the third to the fourth decades (28.7% versus 63.6%, p<0.001) with a similar fashion to smoking. Hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, impaired glucose tolerance (IGT), and WCH had a similar fashion with excess weight by increasing until the seventh decade and decreasing afterwards (p<0.05 nearly in all steps). Whereas hypertension (HT), type 2 diabetes mellitus (DM), and coronary heart disease (CHD) always increased without any decrease by decades (p<0.05 nearly in all steps), indicating their irreversible natures. CONCLUSION WCH may be an initial sign of the systemic atherosclerotic process that can be detected easily and prevented by a trend towards weight loss.

Abstract
BACKGROUND Aspirin reduces the odds of an arterial thrombotic event in high-risk patients. However, 10%-20% of patients with an arterial thrombotic event who are treated with aspirin have a recurrent arterial thrombotic event during long-term followup. Aspirin resistance has been described in some patient populations such as those with an acute coronary syndrome, ischemic stroke, percutaneous coronary intervention with drug-eluting stent, stent re-stenosis, and diabetes mellitus (DM). The aim of this study was to assess aspirin resistance and to compare it to the use of oral anti-diabetic drugs and insulin in patients with diabetes. METHODS AND RESULTS Platelet aggregation was measured after aspirin treatment in 101 diabetic patients undergoing percutaneous coronary intervention. Two patient populations were included in the investigation: use of insulin (group 1) and use of oral anti-diabetic agents (OAD) (group 2) in diabetic patients. Platelet aggregation was determined using a multichannel Multiplate analyzer. Among group 1 patients, 4.7% were aspirin non-responders and among group 2 patients, 8.6% were aspirin non-responders. Statistical differences were not found between the groups (p = 0.359). CONCLUSIONS This study demonstrated that there was no significant difference in aspirin resistance between type 2 diabetes mellitus patients on insulin treatment and type 2 diabetes mellitus patients on OAD treatment.
