Abstract Background Oral anticoagulation (OAC) is paramount to effective thromboprophylaxis; yet adherence to OAC remains largely suboptimal in patients with atrial fibrillation (AF). Purpose We aimed to assess the impact of an educational, motivational intervention on the adherence to OAC in patients with non-valvular AF. Methods Hospitalised patients with non-valvular AF who received OAC were randomly assigned to usual medical care or a proactive intervention, comprising motivational interviewing and tailored counseling on medication adherence. The primary study outcome was adherence to OAC at 1-year, evaluated as Proportion of Days Covered (PDC) by OAC regimens and assessed through nationwide prescription registers. Secondary outcomes included the rate of persistence to OAC, gaps in treatment, proportion of VKA-takers with labile INR (defined as time to therapeutic range<70%) and clinical events. Results A total of 1009 patients were randomised, 500 in the intervention group and 509 in the control group. At 1-year follow-up, 77.2% (386/500) of patients in the intervention group had good adherence (PDC>80%), compared with 55% (280/509) in the control group (adjusted odds ratio 2.84, 95% confidence interval 2.14–3.75; p<0.001). Mean PDC±SD was 0.85±0.26 and 0.75±0.31, respectively (p<0.001). Patients that received the intervention were more likely to persist in their OAC therapy at 1 year, while usual medical care was associated with more major (≥3 months) treatment gaps [Figure]. Among 212 VKA-takers, patients in the intervention group were less likely to have labile INR compared with those in the control group [21/120 (17.1%) vs 34/92 (37.1%), OR 0.33 95% CI 1.15–0.72, p=0.005]. Clinical events over a median follow-up period of 2 years occurred at a numerically lower, yet non-significant, rate in the intervention group [Table]. Conclusions In patients receiving OAC therapy for non-valvular AF, a motivational intervention significantly improved patterns of medication adherence, without significantly affecting clinical outcomes.

Abstract Background The optimal timing for starting anticoagulation after an acute ischemic stroke related to non-valvular atrial fibrillation (AF) remains a challenge, especially in patients treated with systemic thrombolysis or mechanical thrombectomy. Purpose We aimed to assess the rates of early recurrence and major bleeding in patients with acute ischemic stroke and AF treated with thrombolytic therapy and/or thrombectomy who received oral anticoagulants for secondary prevention. Methods We combined the dataset of the RAF and the RAF-NOACs studies, which were prospective observational studies carried out from January 2012 to March 2014 and April 2014 to June 2016, respectively. We included consecutive patients with acute ischemic stroke and AF treated with either vitamin K antagonists (VKAs) or new oral anticoagulants (NOACs). Primary outcome was the composite of stroke, transient ischemic attack, symptomatic systemic embolism, symptomatic cerebral bleeding, and major extracerebral bleeding within 90 days from the inclusion. Results A total of 2,159 patients were included in the RAF and RAF-NOACs trials, of which 564 patients (26%) were treated with urgent reperfusion therapy. After acute stroke, 505 (90%) patients treated with reperfusion and 1,287 out of the 1,595 (81%) patients not treated with reperfusion started oral anticoagulation. Timing of starting oral anticoagulation was similar in reperfusion-treated and untreated patients (13.5±23.3 vs 12.3±18.3 days, respectively, p=0.287). At 90 days, the composite rate of recurrence and major bleeding occurred in 37 (7%) of patients treated with reperfusion treatment and in 139 (9%) of untreated patients (p=0.127). Twenty-four (4%) reperfusion-treated patients and 82 (5%) untreated patients had early recurrence while major bleeding occurred in 13 (2%) treated and in 64 (4%) untreated patients, respectively. Seven patients in the untreated group experienced both an ischemic and hemorrhagic event. Figure 1 shows the risk of early recurrence and major bleeding over time in patients treated and not treated with reperfusion treatments. The use of NOACs was associated with a favorable rate of the primary outcome compared to VKAs (Odd ratio 0.4, 95% Confidence Interval 0.3–0.7). Conclusions Reperfusion treatment did not influence the risk of early recurrence and major bleeding in patients with AF-related acute ischemic stroke who started anticoagulant treatment.

Oral Anticoagulation Therapy

Abstract Background Atrial fibrillation (AF) is the most frequently sustained cardiac arrhythmia, with a prevalence of about 2–3% in the general population. In accordance with CHADS2 or CHA2DS2-VASc score, appropriate oral anticoagulation therapy such as warfarin or direct oral anticoagulants (DOAC) significantly reduced the risk of thromboembolic events. However, left atrial (LA) thrombus can be detected in the LA appendage (LAA) in AF patients despite appropriate oral anticoagulation therapy. Purpose Our purpose was to investigate the associated factors of LAA thrombus formation in non-valvular atrial fibrillation (NVAF) patients despite under appropriate oral anticoagulation therapy. Methods We retrospectively studied consecutive 286 NVAF patients for scheduled catheter ablation or electrical cardioversion for AF in our institution between February 2017 and September 2019. Mean age was 67.1±9.4 years, 79 patients (29.5%) were female, and 140 (52.2%) were paroxysmal AF. All patients underwent transthoracic and transesophageal echocardiography before catheter ablation or electrical cardioversion. All patients received appropriate oral anticoagulation therapy including warfarin or DOAC for at least 3 weeks prior to transesophageal echocardiography based on the current guidelines. LAA thrombus was defined as an echodense intracavitary mass distinct from the underlying endocardium and not caused by pectinate muscles by at least three senior echocardiologists. Results Of 286 NVAF patients with under appropriate oral anticoagulation therapy, LAA thrombus was observed in 9 patients (3.3%). Univariate logistic regression analysis showed that age, paroxysmal AF, CHADS2 score ≥3, left ventricular end-diastolic volume index (LVEDVI), left ventricular ejection fraction (LVEF), left ventricular mass index (LVMI), LA volume index (LAVI), mitral inflow E and mitral e' annular velocities ratio (E/e'), and LAA flow were associated with LAA thrombus formation. It was noteworthy that multivariate logistic regression analysis showed that LAA flow was independent predictor of LAA thrombus (OR: 0.72, 95% CI: 0.59–0.89, p<0.005) as well as LVEF. Furthermore, receiver operating characteristic (ROC) curve analysis identified the optimal cutoff value of LAA flow for predicting LAA thrombus as ≤15cm/s, with a sensitivity of 88%, specificity of 93%, and area under the curve (AUC) of 0.95. Conclusions LAA flow was strongly associated with LAA thrombus formation even in NVAF patients with appropriate oral anticoagulation therapy. According to our findings, further strengthen of oral anticoagulation therapy or percutaneous transcatheter closure of the LAA may be considered in NVAF patients with appropriate oral anticoagulation therapy but low LAA flow, especially <15cm/s.
