Atrial fibrillation (AF) is the most common arrhythmia in the adult population, and the number of patients with this arrhythmia will increase in the future. As a result, the number of patients taking anticoagulants (ACs), which are considered "high alert medication" is constantly increasing. The aim. To highlight the problems of ACs use in patients with non-valvular AF in real clinical practice, to consider the therapy safety and treatment adherence. The main body. Approval of new oral ACs has provided more options to clinicians and patients, but even with their use, errors are possible that increase the risk of bleeding. Mistakes can be made by both patients and doctors. The introduction of training as a mandatory element in the complex therapy of AF helps to reduce the number of errors that the patient could make. The clinical condition, the availability of monitoring and the patient's wishes for treatment may change over time, and this may lead to the need to switch the AC, which is potentially dangerous in terms of side effects. The risk of bleeding increases regardless of the direction of change of AC - the very fact of transition is important. Doctor`s errors play a significant role in the risk increase at this stage, and it is important to raise their awareness of the rules for the ACs switch to avoid bleeding. The article presents the rules of transition from one oral AC to another, following which doctors will minimize the risk of side effects in clinical practice. Conclusion. The use of AC for patients with AF is life-saving, but if used improperly, life-threatening side effects can occur. According to research, in many cases, the development of the latter could be prevented primarily through patient education and the proper doctor training.

Background: Oral anticoagulation (OAC) is effective at preventing stroke in patients with atrial fibrillation (AF), yet warfarin is often poorly tolerated. Non-vitamin K oral anticoagulants (NOACs) are as or more effective as warfarin, yet their tolerance and persistence in clinical practice is not known. Methods: We assessed patterns of persistent OAC use among 2,345 AF patients starting on therapy in the ORBIT-AF II registry (71% starting on a NOAC, and 29% on warfarin). Results: By 6 months, 364 (22%) patients started on a NOAC had discontinued or changed initial therapy versus 143 (21%) started on warfarin initially (p=0.5). Among warfarin users, patients who switched or discontinued therapy were of similar age (median ages 72 and 74 vs. 74 for stable users, p=0.7) and CHA2DS2-VASc scores (mean 98 and 3.66 vs. 3.84, p=0.4). Among NOAC users, those who discontinued treatment were younger (median age 68 vs. 73 for those who switched and 72 for stable users; p=0.0004), and lower CHA2DS2-VASc scores (3.02 vs. 3.58 and 3.47, respectively; p=0.0008). The median time to change or discontinuation was more rapid in those started on a NOAC vs warfarin (97 days vs. 122 days, p=0.003). Among those on warfarin at baseline, 7.6% (n=52) were switched to a NOAC within 6 months, whereas transitions from NOAC to warfarin was 2.5% (n=42).Transitions among NOACs occurred in 9.8%, 3.2%, and 5.5% of patients on baseline dabigatran, rivaroxaban, and apixaban, respectively. Physician preference was the most common reason for both OAC and warfarin changes (Table). Drug cost was the primary reason for change of therapy in 15% of NOAC users (vs. 0 for warfarin). Conclusions: At 6-month follow-up, one in five newly started on OAC had discontinued or changed. These rates of change were similar among warfarin and NOAC treated patients. Cost concerns drove discontinuation in a modest number of patients, however, cost concerns were more prevalent in NOAC-treated patients.

Abstract Background and purpose Amiodarone is commonly use in patients with atrial fibrillation (AF), but the organ toxicity side effects limit its long-term use. We investigated the rates of and reasons for permanent amiodarone discontinuation among patients with AF in contemporary clinical practice. Methods A single-centre, ongoing, registry-based observational longitudinal study included consecutive AF patients prescribed with amiodarone in our hospital from January 2015 to December 2017. All patients underwent a loading protocol of 400–600 mg of amiodarone daily for 1–2 weeks, followed by 200–400mg daily for 4–8 weeks and 200mg daily or 1000mg weekly thereafter. Results Of 657 AF patients taking amiodarone (Mean age 62.2±11.0, female n=215 (32.6%), hypertension n=504 (76.7%), diabetes mellitus n=107 (16.3%), coronary arterial disease n=139 (19.8%), History of Myocardial infarction 86 (13.1%), Stroke/TIA 60 (9.1%), chronic kidney disease 157 (23.9%)), the drug was permanently discontinued in total of 248 patients (37.7%). The reasons for amiodarone discontinuation are shown in Figure. On multivariable Cox-regression analysis, physician's decision (HR 5.6; 95% CI 3.9–7.9, p<0.001) and amiodarone side effects (HR 3.9; 95% CI 2.9–5.1, p<0.001) were significantly associated with permanent amiodarone discontinuation. The overall time to discontinuation was 23.2±24.1 months. Compared with others, time to discontinuation was shorter in patients post AF ablation (17.3±21.3 vs 24.5±24.5, p=0.05), longer in those with AF progression (29.2±31.0 vs 20.9±20.3, p=0.014) and similar in patients with amiodarone side effects (23.7±17.7 vs 23.0±26.8, p=0.813). Pulmonary toxicity and proarrhythmia were not observed among study patients (Figure). Chart 1 Conclusion Our study showed that permanent discontinuation of amiodarone in contemporary clinical practice was due to the drug side effects in 12% of amiodarone-treated AF patients, occurring after a mean 2-year treatment course. The most prevalent side effect was thyroid dysfunction, whereas the prevalence of proarrhythmic effect was low. Notably, physician's fear of complications (which may not always be justified), also was an independent driver of permanent amiodarone discontinuation. More data are needed to inform optimal amiodarone use in AF patients in daily practice.

In real clinical practice more and more often doctors treat comorbid patients. The high prevalence of cardiovascular diseases with various comorbid conditions contributes to the progressive increase in the number of patients with a concurrence of several diseases. A comorbid patient is a serious problem for any clinician, since in this case it is necessary to take into account several components of therapy, which makes it difficult to control treatment efficiency, contributes to an increase in polypharmacy, the risk of local and systemic side effects of drugs, and reduces adherence to therapy. A comorbid patient is a serious problem for any clinician. The paper describes and discusses the clinical case of a comorbid patient, who admitted to the cardiological department initially but he had also rheumatological problems (gout), kidney affection.

Aim: to elucidate risk factors of development of atrial fibrillation (AF) in patients with acute coronary syndrome (ACS), and to assess of patient’s adherence to oral anticoagulant therapy (OAT) during 12 months after ACS episode according to the data of the Total ACS Registry for the Krasnodar Territory.Materials and methods. In this retrospective analysis we used Registry data on patients with ACS and concomitant AF, consecutively admitted to cardiological departments of the S.V. Ochapovsky Territorial Clinical Hospital from 20/11/2015 to 20/02/18. Number of patients in the analyzed group was 201 (52 with AF which first appeared in connection with the index ACS). Survivors after hospital discharge were contacted by telephone and at planned visits. The analysis included assessment of rates of the following outcomes: inhospital death, hemorrhagic and thromboembolic complications, prognostic efficacy of the CRISADE and HAS BLED scores, and expediency of prescription to patients with ACS and concomitant first AF episode of prolonged OAT after hospital discharge.Results. Demographic and anamnestic data of patients with the first AF attack at the background of ACS were like those of patients with other types of AF. This group of patients was characterized by more severe course of the disease, but this produced no impact on inhospital mortality and rate of complications, as well as on mortality for 12 months after hospital discharge.Conclusion. The results of this analysis are important for understanding distinctive characteristics of patients with AF first developed during ACS.

Anticoagulant therapy in elderly patients with atrial fibrillation and concomitant diseases is often the challenge for clinicians. The high risk of stroke is inherent in atrial fibrillation, and it increases when combined with coronary heart disease and chronic kidney disease. On the other hand, the comorbidity increases the risk of bleeding. Older age is also the risk factor of thrombotic and hemorrhagic complications. As a consequence, the choice of specific anticoagulant should be based on a solid evidences, obtained both from randomized clinical trials and from daily clinical practice. In the ROCKET AF trail the direct oral anticoagulant rivaroxaban showed a tendency to reduce the risk of thromboembolism by 20% compared with warfarin in the patients aged 75 years and older. The safety of rivaroxaban has been evaluated in the XANTUS POOLED program. According to the follow-up results for 12 months, more than 96% of patients didn't have any adverse event, and the number of patients with major bleeding was 1.5%. Several meta-analyzes reported a reduction of cardiovascular complications in patients treated by rivaroxaban. In the ROCKET AF trail, a “renal” dose of rivaroxaban (15 mg OD) was studied in patients with chronic kidney disease. The efficacy and safety of rivaroxaban were validated in this patients, and a simple algorithm for selecting the dose of this drug in patients with chronic kidney disease was provided.

Background: The use of nonsteroidal anti-inflammatory drugs (NSAIDs) with oral anticoagulants has been associated with an increased risk of bleeding. We investigated the risk of bleeding and major cardiovascular outcomes in patients with atrial fibrillation taking NSAIDs and apixaban or warfarin. Methods: The ARISTOTLE trial (Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation; n=18 201) compared apixaban with warfarin in patients with atrial fibrillation at an increased risk of stroke. Patients in ARISTOTLE without severe renal (creatine clearance ≤30 mL/min) or liver disease were included in this analysis (n=17 423). NSAID use at baseline, NSAID use during the trial (incident NSAID use), and never users were described. The primary outcome was major bleeding. Secondary outcomes included clinically relevant nonmajor bleeding, gastrointestinal bleeding, heart failure hospitalization, stroke or systemic embolism, and all-cause mortality. NSAID use during the trial, and the interaction between randomized treatment, was analyzed using time-dependent Cox proportional hazards models. Results: Those with baseline NSAID use (n=832 [4.8%]), incident NSAID use (n=2185 [13.2%]), and never users were similar in median age (age [25th, 75th]; 70 [64, 77] versus 70 [63, 75] versus 70 [62, 76]). Those with NSAID use at baseline and incident NSAID use were more likely to have a history of bleeding than never users (24.5% versus 21.0% versus 15.6%, respectively). During a median follow-up (25th, 75th) of 1.8 (1.4, 2.3) years and when excluding those taking NSAID at baseline, we found that incident NSAID use was associated with an increased risk of major bleeding (hazard ratio [HR], 1.61 [95% CI, 1.11–2.33]) and clinically relevant nonmajor bleeding (HR, 1.70 [95% CI, 1.16–2.48]), but not gastrointestinal bleeding. No significant interaction was observed between NSAID use and randomized treatment for any outcome. Conclusions: A substantial number of patients in the ARISTOTLE trial took NSAIDs. Incident NSAID use was associated with major and clinically relevant nonmajor bleeding, but not with gastrointestinal bleeding. The safety and efficacy of apixaban versus warfarin appeared not significantly to be altered by NSAID use. This study warrants more investigation of the effect of NSAIDs on the outcomes of patients treated with apixaban. Clinical Trial Registration: URL: https://www.clinicaltrials.gov .
