Non-vitamin K antagonist oral anticoagulants (DOACs) are known to be more effective than vitamin K antagonists (VKAs) in preventing thromboembolism. The aim was to identify clinical factors associated with hemorrhagic events in AF patients treated with DOACs and to develop a simple, clinically applicable bleeding risk score. Methods: Data were derived from the multicenter CRAFT trial (NCT02987062) . We conducted a retrospective analysis of hospital records of 1435 AF patients (median age: 67 years; 44.8% female) treated with dabigatran or rivaroxaban. The main study endpoints were the occurrence of a bleeding episode, thromboembolic episode, or all-cause death during a mean four-year followup (1531 [1062–2140] days) . Results: The rates of bleeding episodes, thromboembolic episodes, and all-cause death were 17.4%, 13.5%, and 23.9%, respectively. Nine factors were identified as predictors of bleeding complications: male sex, history of major bleeding, history of cancer, COPD, CRT, rivaroxaban therapy, statin therapy, age, and absence of heart failure. Based on these, the CRAFT bleeding score was developed to predict the risk of hemorrhagic events in individual patients. Conclusions: The CRAFT bleeding score may be implemented in AF patients as an additional tool for evaluating DOACs safety prior to initiating anticoagulant therapy, and for guiding closer monitoring of high-risk individuals to minimize bleeding complications.  \nKeywords: atrial fibrillation; bleeding risk score; anticoagulant therapy; DOACs  \n1. Introduction  \nAnticoagulant therapy is essential for patients with atrial fibrillation (AF), as it prevents thrombotic complications, most importantly ischemic stroke. Except for patients at very low thrombotic risk, it is widely used [1–3] . However, it carries well-recognized side effects such as hemorrhagic complications.  \nIn recent years, the management of atrial fibrillation has evolved substantially with the introduction of non-vitamin K antagonist oral anticoagulants (DOACs), including dabigatran, rivaroxaban, apixaban, and edoxaban. DOACs have been shown to provide several advantages over vitamin K antagonists (VKAs), both in preventing thromboembolic  \nepisodes and reducing the frequency of bleeding complications [4–6] . These agents provide predictable pharmacokinetics, fewer drug–food interactions, and do not require routine INR monitoring, which has significantly improved patient convenience. However, despite their favorable safety profile compared to warfarin, bleeding events remain a relevant clinical concern. Several bleeding risk scores have been proposed, such as HAS-BLED and, more recently, the DOAC score, but th","cbCaibeWGcAcJEH5","https://ap.wps.com/l/cbCaibeWGcAcJEH5","pdf",412045,"English","# Abstract\n## Background/Objectives\n## Methods\n## Results\n## Conclusions\n# Introduction\n# Materials and Methods\n## Study Design","[{\"question\":\"What was the primary goal of the CRAFT study regarding hemorrhagic events?\",\"answer\":\"To identify clinical factors associated with hemorrhagic events in AF patients treated with DOACs and to develop a simple, clinically usable bleeding risk score.\"},{\"question\":\"Which DOACs were evaluated in the retrospective cohort?\",\"answer\":\"Patients were treated with dabigatran or rivaroxaban in the CRAFT registry.\"},{\"question\":\"What factors were identified as predictors of bleeding complications?\",\"answer\":\"Nine predictors were reported: male sex, history of major bleeding, history of cancer, COPD, CRT, rivaroxaban therapy, statin therapy, age, and absence of heart failure.\"}]","Hemorrhagic Complications in Patients with Atrial Fibrillation Treated with Novel Oral Anticoagulants - Results from the CRAFT Study | PDF",1790761729,23]
