Objective: 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.
Predictive Value of Red Cell Distribution Width in Intrahospital Mortality and Postintervention Thrombolysis in Myocardial Infarction Flow in Patients With Acute Anterior Myocardial Infarction

Objectives Recent studies have reported a strong independent association between increased red cell distribution width (RDW) and the risk of adverse outcomes in patients with heart failure, stable coronary disease, and acute coronary syndromes. However, in this study we aimed to determine the impact of an elevated RDW level on the postinterventional thrombolysis in myocardial infarction (TIMI) flow and intrahospital mortality in patients with acute anterior myocardial infarction (AMI). Methods A total of 763 patients with acute AMI undergoing a primary percutaneous coronary intervention were evaluated retrospectively. Upon admission, the RDW level was measured by an automated complete blood count. Postinterventional TIMI flow and intrahospital mortality was documented for all patients from hospital registries. The patients were classified according to the RDW level. RDW more than 14.8% was defined as elevated RDW. All groups were compared statistically according to the preinterventional characteristics. Results Elevated RDW was found to be an independent predictor of increased intrahospital mortality in multivariate regression analysis (hazard ratio: 3.677, 95% confidence interval: 1.228-11.008, P=0.02). Other independent predictors for intrahospital mortality were diabetes mellitus (hazard ratio: 6.743, 95% confidence interval: 1.941-23.420, P=0.003), smoking (hazard ratio: 6.779, 95% confidence interval: 1.505-30.534, P=0.013), and creatinine more than 0.8 mg/dl (hazard ratio: 7.982, 95% confidence interval: 1.759-36.211, P=0.007). However, there were no independent predictors for TIMI including elevated RDW. Conclusion A high admission RDW level in patients with acute AMI undergoing a primary percutaneous coronary intervention was associated with an increased risk for intrahospital cardiovascular mortality, but was not associated with worse postinterventional TIMI flow.
