    Objectives: Atrial fibrillation (AF) is one of the most common causes of preventable ischemic stroke and is related to increased cardiovascular morbidity and mortality. There is a lack of data in Turkey on the use of new oral anticoagulants (NOACs), and time in therapeutic INR range (TTR) in vitamin K antagonist users and AF management modality. In this multi-center trial, we aimed to analyze, follow and evaluate the epidemiological data in non-valvular AF patients. Study design: Four thousand one hundred consecutive adult patients from 42 centers with at least one AF attack identified on electrocardiography will be included in the study. Patients with rheumatic mitral valve stenosis and prosthetic valve disease will be excluded from the study. At the end of one year, the patients will be evaluated in terms of major cardiac end points (death, transient ischemic attack, stroke, systemic thromboembolism, major bleeding and hospitalization). Results: First results are expected in June 2015. Data about major cardiovascular end-points will be available in January 2016. Conclusion: The rates and kind of oral anticoagulant use, TTR in vitamin K antagonist users and main management modality applied in non-valvular AF patients will be determined by AFTER-2 study. In addition, the rate of major adverse events (MACEs) and the independent predictors of these MACEs will be detected (AFTER-2 Study ClinicalTrials.gov number, NCT02354456.).

    Incidence and Predictors of Radial Artery Occlusion Associated Transradial Catheterization
    (Ivyspring Int Publ, 2013) Tuncez, Abdullah; Kaya, Zeynettin; Aras, Dursun; Yildiz, Abdulkadir; Gul, Enes Elvin; Tekin-alp, Mehmet; Karakas, Mehmet Fatih
    In this study, we sought to assess the incidence and predictors of radial artery occlusion (RAO), which is a significant complication of transradial cardiac catheterization. We prospectively evaluated the results of 106 patients who underwent coronary angiography and percutaneous coronary intervention (PCI) via the transradial approach (TRA). At the 3rd h of intervention, the radial artery was checked by palpation; color doppler ultrasonography was performed at the 24th h. Fluoroscopy duration, procedure success, and complications of the radial artery were recorded. The procedure was successfully completed in all patients. RAO was detected in eight female and two male patients. In terms of RAO, there was a statistically significant difference between males and females (p=0.019). Other parameters did not show a significant correlation with RAO. Altough did not have any effect on procedural success, eight patients developed transient radial artery spasm. Gender was not associated with radial arterial spasms (p=0.19). TRA in the diagnosis and treatment of coronary artery disease has shown high procedural success and low complication rates; it addition, it presents a low economic burden. It should be used widely and be involved in the routine cardiology residency program.

    Utility of Neutrophil-Lymphocyte Ratio in Predicting Troponin Elevation in the Emergency Department Setting
    (Sage Publications Inc, 2015) Korkmaz, Ahmet; Yildiz, Abdulkadir; Gunes, Harun; Duyuler, Serkan; Tuncez, Abdullah
    There is little data regarding the diagnostic ability of neutrophil-lymphocyte ratio (NLR) in acute coronary syndrome. Therefore, we aimed to assess the predictive value of NLR in the discrimination of troponin-positive patients. We enrolled 244 patients (mean age 61.3 +/- 11.7 years, 70.5% male) who presented to the emergency service with acute chest pain. Patients were divided into 2 groups based upon the troponin positivity in the 12- to 24-hour follow-up. The admission NLR was significantly higher in the troponin-positive group (5.49 +/- 4.01 vs 2.40 +/- 1.36, P < .001). A cutoff point of 2.80 for NLR measured on admission had 79% sensitivity and 73% specificity in predicting follow-up troponin positivity. After multivariate analysis, admission NLR and glucose levels remained significant predictors of follow-up troponin positivity. In conclusion, NLR may be an early diagnostic marker in emergency service for discriminating patients who will have a positive troponin test in the follow-up.

    What have we learned from Turkish familial hypercholesterolemia registries (A-HIT1 and A-HIT2)?
    (Elsevier Ireland Ltd, 2018) Kayikcioglu, Meral; Tokgozoglu, Lale; Dogan, Volkan; Ceyhan, Ceyhun; Tuncez, Abdullah; Kutlu, Merih; Onrat, Ersel
    Background and aims: Familial hypercholesterolemia (FH) is a common genetic disease of high-level cholesterol leading to premature atherosclerosis. One of the key aspects to overcome FH burden is the generation of largescale reliable data in terms of registries. This manuscript underlines the important results of nation-wide Turkish FH registries (A-HIT1 and A-HIT2). Methods: A-HIT1 is a survey of homozygous FH patients undergoing low density lipoprotein (LDL) apheresis (LA). A-HIT2 is a registry of adult FH patients (homozygous and heterozygous) admitted to outpatient clinics. Both registries used clinical diagnosis of FH. Results: A-HIT1 evaluated 88 patients (27 +/- 11 years, 41 women) in 19 centers. All patients were receiving regular LA. There was a 7.37 +/- 7.1-year delay between diagnosis and initiation of LA. LDL-cholesterol levels reached the target only in 5 cases. Mean frequency of apheresis sessions was 19 +/- 13 days. None of the centers had a standardized approach for LA. Mean frequency of apheresis sessions was every 19 +/- 13 (7-90) days. Only 2 centers were aware of the target LDL levels. A-HIT2 enrolled 1071 FH patients (53 +/- 8 years, 606 women) from 31 outpatients clinics specialized in cardiology (27), internal medicine (1), and endocrinology (3); 96.4% were heterozygous. 459 patients were on statin treatment. LDL targets were attained in 23 patients (2.1% of the whole population, 5% receiving statin) on treatment. However, 66% of statin-receiving patients were on intense doses of statins. Awareness of FH was 9.5% in the whole patient population. Conclusions: The first nationwide FH registries revealed that FH is still undertreated even in specialized centers in Turkey. Additional effective treatment regiments are urgently needed.
