Öğe New oral anticoagulants-TURKey (NOAC-TURK): Multicenter cross-sectional study(Turkish Soc Cardiology, 2017) Altay, Servet; Yildirimturk, Ozlem; Cakmak, Huseyin Altug; Askin, Lutfu; Sinan, Umit Yasar; Besli, Feyzullah; Gedikli, OmerObjective: New oral anticoagulants (NOACs) are increasingly used both for prevention of stroke in non-valvular atrial fibrillation (NVAF) and the treatment of venous thromboembolism (VTE). In this study, we aimed to evaluate the current patterns of NOACs treatment in Turkey. Moreover, demographic and clinical parameters and bleeding and/or embolic events under NOACs treatment were analyzed. Methods: The New Oral Anticoagulants-TURKey (NOAC-TURK) study was designed as a multicenter cross-sectional study. A total of 2,862 patients from 21 different centers of Turkey under the treatment of NOACs for at least three months were included in this study. Demographic, clinical, and laboratory characteristics of study participants with their medications used were obtained through the NOAC-TURK survey database. Additional necessary medical records were obtained from electronic health records of participating centers. Results: Of the 2. 862 patients, 1.131 (39.5%) were male and the mean age was 70.3 +/- 10.2 years. Hypertension was found as the most frequent comorbidity (81%). The most common indication for NOACs was permanent atrial fibrillation (83.3%). NOACs were mainly preferred because of inadequate therapeutic range or overdose during warfarin usage. The most frequent complication was bleeding (n=217, 7.6%), and major bleeding was observed in 1.1% of the patients. Embolic events were observed in 37 patients (1.3%). Rivaroxaban and dabigatran were both more preferred than apixaban. Almost half of the patients (47.6%) were using lower doses of NOACs, which is definitely much more than expected. Conclusion: The NOAC-TURK study showed an important overview of the current NOACs treatment regimens in Turkey. Although embolic and bleeding complications were lower than or similar to previous studies, increased utilization of low-dose NOACs in this study should be considered carefully. According to the results of this study, NOACs treatment should be guided through CHA(2)DS(2)-VASc and HASBLED scores to ensure more benefit and less adverse effects in NVAF patients.Öğe Real-life data of major and minor bleeding events with direct oral anticoagulants in the one-year follow-up period: The NOAC-TURK study(Turkish Soc Cardiology, 2021) Gedikli, Omer; Altay, Servet; Unlu, Serkan; Cakmak, Huseyin Altug; Askin, Lutfu; Yanik, Ahmet; Besli, FeyzullahObjective: This study aimed to evaluate the safety of direct oral anticoagulants (DOACs) in patients with non-valvular atrial fibrillation (NVAF) during daily clinical practice. Methods: This was a prospective study conducted between January 01, 2016, and April 01, 2017, in patients aged >= 18 years with a diagnosis of NVAF. We performed the study in 9 clinical centers from different regions of Turkey, and the mean follow-up period was 12+2 months. We investigated major and minor bleeding events of DOAC. Results: A total of 1807 patients with NVAF were enrolled. The mean age of the patients was 73.6 +/- 10.2 years, CHA2DS2-VASc score was 3.6 +/- 1.4, and HAS-BLED score was 2 +/- 1.2. The most frequently prescribed DOAC was dabigatran 110 mg bid in 409 (22.6%) patients. The patients on apixaban 2.5 mg bid were older (p<0.001). Patients on rivaroxaban 15 mg od also had a higher prevalence of chronic renal failure, 46 (16.7%) patients. A total of 205 (11.4%) bleeding events were observed; among these, 34 (1.9%) patients had major bleeding and 171 (9.4%) patients had minor bleeding. The major and minor bleeding events were 2/273 (0.7%) and 30/273 (10.9%) in patients receiving dabigatran 150 mg bid, 13/409 (3%) and 44/409 (10.7%) in patients receiving dabigatran 110 mg bid, 4/385 (1%) and 42/385 (10.9%) in patients receiving rivaroxaban 20 mg od, 8/276 (2.9%) and 27/276 (9.7%) in patients receiving rivaroxaban 15 mg od, 3/308 (0.9%) and 14/308 (4.5%) in patients receiving apixaban 5 mg bid, 4/156 (2.5%) and 14/156 (9%) in patients receiving apixaban 2.5 mg bid, respectively. The total bleeding events were 17 (5.6%) in patients receiving apixaban 5 mg, less than those receiving other DOACs. On multivariate analyses, rivaroxaban 20 mg od (p=0.002), ATRIA and HAS-BLED scores, and peripheral artery disease were independent indicators of bleeding. The most frequent location of major bleeding was the gastrointestinal system (GIS) [17 (0.9%) patients], and the most frequent location of minor bleeding was the gingiva [45 (2.5%) patients]. Conclusion: This study showed that similar results as the previous real-life study; however, we had some different results, such as the GIS tract bleeding was more frequent in patients receiving dabigatran 110 mg bid. The major and intracranial bleeding events were similar for different DOACs; and among DOACs, only rivaroxaban 20 mg od was associated with a high risk of bleeding.Öğe Real-World Data on the Incidence of Stroke, Myocardial Infarction, and Mortality Among Nonvalvular Atrial Fibrillation Patients in Türkiye: New Oral Anticoagulants-TURKey Study(Kare Publ, 2024) Unlu, Serkan; Altay, Servet; Gedikli, Omer; Ozden, Ozge; Canpolat, Ugur; Askin, Lutfu; Yayla, CagriBackground: Atrial fibrillation (AF) is strongly associated with an increased risk of isch- emic events. Anticoagulation focuses on reducing the risk of embolism. Guideline recom- mended CHA2DS2-VASc scoring system is most widely used; however, different scoring systems do exist. Thus, we sought to assess the impact of anticoagulant treatment and different scoring systems on the development of stroke, myocardial infarction, and allcause mortality in patients with nonvalvular AF. Methods: The present study was designed as a prospective cohort study. The enrollment of the patients was conducted between August 1, 2015, and January 1, 2016. The followup period was defined as the time from enrollment to the end of April 1, 2017, which also provided at least 12 months of prospective follow-up for each patient. Results: A total of 1807 patients with AF were enrolled. During the follow-up, 2.7% (48) of patients had stroke, 0.8% (14) had myocardial infarction, and 7.5% (136) died. The antico- agulation and risk factors in AF (ATRIA) score had a better accuracy for the prediction of stroke compared to other scoring systems (0.729, 95% CI, 0.708-0.750, P < .05). Patients under low -dose rivaroxaban treatment had significantly worse survival (logrankP < .001). Age, CHA2DS2-VASc score, R2CHADS2 score, ATRIA score, chronic heart failure, prior stroke, and being under low -dose rivaroxaban treatment were independent predictors of clinical endpoint (P < .001). Conclusion: Low -dose rivaroxaban treatment was independently and strongly associated with the combined clinical endpoint. Furthermore, the ATRIA score proved to be a stronger predictor of stroke in the Turkish population.Öğe Reply to Letter to the Editor: Can Differences in Non-Vitamin KAntagonist Oral Anticoagulant Preferences Result in Varying Clinical Outcomes in Patients with Atrial Fibrillation?(Kare Publ, 2024) Unlu, Serkan; Altay, Servet; Gedikli, Omer; Ozden, Ozge; Canpolat, Ugur; Askin, Lutfu; Yayla, Cagri[Abstract Not Available]
