Background: Poor time in therapeutic range (TTR) control is associated with an increased risk of stroke and bleeding in atrial fibrillation (AF) patients receiving warfarin. This study aimed to determine whether the physician–pharmacist collaborative clinic (PPCC) model could improve the anticoagulation quality as well as to create a nomogram for predicting anticoagulation quality in AF patients.Methods: This retrospective observational study enrolled AF patients who either initially received warfarin or returned to warfarin after withdrawal between January 1, 2016 and January 1, 2021, at our institution. The primary outcome was dynamic changes in TTRs (a TTR of ≥60% considered high anticoagulation quality). The secondary outcomes were thromboembolic and bleeding events during follow-up. We compared the dynamic changes in TTRs between the general clinic (GC) and PPCC groups in both the original and propensity score matching (PSM) cohorts. In addition, we explored the potential predictors of high anticoagulation quality and subsequently formulated a nomogram to predict anticoagulation quality.Results: A total of 265 patients with AF were included, comprising 57 patients in the PPCC group and 208 patients in the GC group. During a median follow-up period of 203 days, the PPCC group had a shorter time (76 vs. 199 days, p < 0.001) and more patients achieved a TTR ≥60% (73.7 vs. 47.1%, p = 0.002 by log-rank test) than the GC group. The results from the PSM cohort confirmed this finding. No significant differences in the incidences of thromboembolic events (5.3 vs. 5.3%, p = 1.000) and bleeding events (4.3 vs. 3.5%, p = 1.000) were observed between the two groups. Four variables were explored as predictors related to high anticoagulation quality: treatment within a PPCC, history of bleeding, history of bleeding, and the presence of more than four comorbidities. The nomogram revealed a moderate predictive ability (c-index: 0.718, 95% confidence interval (95%CI): 0.669–0.767) and a moderately fitted calibration curve.Conclusion: The PPCC model contributed to improved anticoagulation quality in AF patients receiving warfarin. The nomogram might be an effective tool to predict anticoagulation quality and could aid physicians and pharmacists in the selection of patients who will likely benefit from sustained and active intervention.

Abstract Background Non-paroxysmal (NPAF) forms of atrial fibrillation (AF) have been reported to be associated with an increased risk for systemic embolism or death. Methods Comparison of procedural details and long-term outcomes in patients (pts) with paroxysmal AF (PAF) against controls with NPAF in the prospective, multicentre observational registry of patients undergoing LAAC (LAARGE). Results A total of 638 pts (PAF 274 pts, NPAF 364 pts) were enrolled. In both groups, a history of PVI was rare (4.0% vs 1.6%, p = 0.066). The total CHA2DS2-VASc score was lower in the PAF group (4.4 ± 1.5 vs 4.6 ± 1.5, p = 0.033), while HAS-BLED score (3.8 ± 1.1 vs 3.9 ± 1.1, p = 0.40) was comparable. The rate of successful implantation was equally high (97.4% vs 97.8%, p = 0.77). In the three-month echo follow-up, LA thrombi (2.1% vs 7.3%, p = 0.12) and peridevice leak > 5 mm (0.0% vs 7.1%, p = 0.53) were numerically higher in the NPAF group. Overall, in-hospital complications occurred in 15.0% of the PAF cohort and 10.7% of the NPAF cohort (p = 0.12). In the one-year follow-up, unadjusted mortality (8.4% vs 14.0%, p = 0.039) and combined outcome of death, stroke and systemic embolism (8.8% vs 15.1%, p = 0.022) were significantly higher in the NPAF cohort. After adjusting for CHA2DS2-VASc and previous bleeding, NPAF was associated with increased death/stroke/systemic embolism (HR 1.67, 95% CI 1.02–2.72, p = 0.041). Conclusion Atrial fibrillation type did not impair periprocedural safety or in-hospital MACE patients undergoing LAAC. However, after one year, NPAF was associated with higher mortality.

Aims Many clinical scores for risk stratification in patients with atrial fibrillation have been proposed, and some have been useful in predicting all-cause mortality. We aim to analyse the relationship between clinical risk score and all-cause death occurrence in atrial fibrillation patients. Methods We performed a systematic search in PubMed and Scopus from inception to 22 July 2017. We considered the following scores: ATRIA-Stroke, ATRIA-Bleeding, CHADS2, CHA2DS2-VASc, HAS-BLED, HATCH and ORBIT. Papers reporting data about scores and all-cause death rates were considered. Results Fifty studies and 71 scores groups were included in the analysis, with 669,217 patients. Data on ATRIA-Bleeding, CHADS2, CHA2DS2-VASc and HAS-BLED were available. All the scores were significantly associated with an increased risk for all-cause death. All the scores showed modest predictive ability at five years (c-indexes (95% confidence interval) CHADS2: 0.64 (0.63–0.65), CHA2DS2-VASc: 0.62 (0.61–0.64), HAS-BLED: 0.62 (0.58–0.66)). Network meta-regression found no significant differences in predictive ability. CHA2DS2-VASc score had consistently high negative predictive value (≥94%) at one, three and five years of follow-up; conversely it showed the highest probability of being the best performing score (63% at one year, 60% at three years, 68% at five years). Conclusion In atrial fibrillation patients, contemporary clinical risk scores are associated with an increased risk of all-cause death. Use of these scores for death prediction in atrial fibrillation patients could be considered as part of holistic clinical assessment. The CHA2DS2-VASc score had consistently high negative predictive value during follow-up and the highest probability of being the best performing clinical score.

The Relationship

The association between the cumulative hypertension burden and the development of atrial fibrillation (AF) is unclear. We aimed to investigate the relationship between hypertension burden and the development of incident AF. Using the Korean National Health Insurance Service database, we identified 3 726 172 subjects who underwent 4 consecutive annual health checkups between 2009 and 2013, with no history of AF. During the median follow-up of 5.2 years, AF was newly diagnosed in 22 012 patients (0.59% of the total study population; 1.168 per 1000 person-years). Using the blood pressure (BP) values at each health checkup, we determined the burden of hypertension (systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg), stratified as 0 to 4 per the hypertension criteria. The subjects were grouped according to hypertension burden scale 1 to 4: 20% (n=742 806), 19% (n=704 623), 19% (n=713 258), 21% (n=766 204), and 21% (n=799 281). Compared with normal people, subjects with hypertension burdens of 1, 2, 3, and 4 were associated with an 8%, 18%, 26%, and 27% increased risk of incident AF, respectively. On semiquantitative analyses with further stratification of stage 1 (systolic BP of 130–139 mm Hg or diastolic BP of 80–89 mm Hg) and stage 2 (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg) hypertension, the risk of AF increased with the hypertension burden by up to 71%. In this study, both a sustained exposure and the degree of increased BP were associated with an increased risk of incident AF. Tailored BP management should be emphasized to reduce the risk of AF.

Abstract BACKGROUND: Consistent with the advanced age at diagnosis (median age ~70 years), most patients with CLL have co-existent health problems. These co-morbidities influence the ability of many CLL patients to tolerate aggressive chemotherapy-based treatment and can also contribute to treatment-related side effects. The recent development of novel signaling inhibitors, particularly the Bruton's tyrosine kinase inhibitor ibrutinib, has been a major treatment advance for patients with CLL. While these agents generally have favorable toxicity profiles relative to standard chemotherapy-based treatments, they are chronic therapies which patients typically stay on for an extended period. Preliminary data suggests ibrutinib may be associated with an increased risk of atrial fibrillation (Afib). In one randomized trial comparing ibrutinib to ofatumumab in patient with relapsed CLL, incident grade 3+ Afib occurred in 3% of ibrutinib treated patients compared to 0% of ofatumumab treated patients (NEJM 371:213). Despite these observations, the baseline frequency of Afib in patients with CLL is not well described - particularly incident atrial fibrillation acquired during the course of the disease. METHODS: We used the Mayo Clinic CLL database to evaluate the prevalence of Afib at the time of CLL diagnosis as well as the incidence of Afib during follow-up. All patients with a new diagnosis of CLL after January 1995 who were seen at Mayo within 12 months of diagnosis were included in the analysis. Afib was identified by chart review and by billing search using ICD9 codes. Data on co-morbid conditions associated with risk of Afib was also abstracted (e.g. hypertension, coronary artery disease [CAD], valvular heart disease, cardiomyopathy, diabetes mellitus, pulmonary disease). RESULTS: A total of 2444 patients with newly diagnosed and previously untreated CLL were seen at Mayo Clinic within 12 months of diagnosis between 1/1995 and 4/2015.Median age at diagnosis was 65 years and 1626 (66.5%) patients were men. A history of Afib was present at the time of CLL diagnosis in 148 (6.1%) patients. Four additional patients had Afib documented in the record but the precise date of onset (e.g. prior to or after CLL diagnosis date) could not be determined. Age, male sex and history of CAD, valvular heart disease, cardiomyopathy, hypertension, and diabetes were associated with a greater likelihood of having a history of Afib at the time of CLL diagnosis (all p<0.01). Among the 2292 patients without a history of Afib at CLL diagnosis, 139 (6.1%) had incident Afib during the course of follow-up for their CLL. The incidence of Afib among patients without a history of Afib at diagnosis was approximately 1%/year (Figure 1A). Considering both Afib present at the time of CLL diagnosis or acquired during the course of the disease, 291 (11.9%) of the 2444 patients in this cohort experienced Afib (median follow-up: 59 months). Among patients without Afib at the time of CLL diagnosis, the following characteristics at the time of CLL diagnosis were associated with an increased risk of incident Afib on multivariate analysis: older age (age 65-74 HR=2.4, p<0.001; age ≥75 HR=3.6, p<0.001), male sex (HR=1.8, p=0.004); valvular heart disease (HR=2.4, p=0.007), and hypertension (HR=1.5; p=0.02). A predictive model for acquired Afib was subsequently constructed based on the independent factors in the Cox regression model. An individual weighted risk score was assigned to each independent factor based on the regression coefficients of the HRs. The Afib risk score (range 0-7) was defined as the sum of the scores of these independent factors. The risk of incident Afib among patients with risk scores of 0-1, 2-3, 4, and 5+ is shown in Figure 1B. Rates for these 4 groups were significantly different (p<0.001), with the 10-year Afib rates (95% C.I.) for those with a score of 0-1, 2-3, 4, and 5+: 4% (2-6%), 9% (6-13%), 17% (11-23%), and 33% (20-43%), respectively. CONCLUSIONS: A history of Afib is present in approximately 1 out of every 16 patients with newly diagnosed CLL. Among patients without Afib at diagnosis, the incidence rate of Afib is ~1%/year. The risk of incident Afib in newly diagnosed CLL patients can be predicted based on age, sex, and co-morbid health conditions present at diagnosis. These data provide context to help interpret data on the frequency of Afib in CLL patients treated with ibrutinib and other novel agents.

Background: Patients treated with hemodialysis and prescribed warfarin typically have lower time in therapeutic range (TTR) compared to the general population. This may result in less benefit or increased risk of over anticoagulation in these patients. Objective: To assess effectiveness of use of an electronic nomogram for the management of warfarin therapy in patients treated with hemodialysis. Design: Retrospective chart review. Setting: Adult patients treated with hemodialysis. Patients: Patients on hemodialysis receiving warfarin for the management of atrial fibrillation (AF) with therapy managed by nursing led electronic nomogram. Measurements: Time in therapeutic range (as fraction and Rosendaal). Methods: Retrospective chart review over 1 year of international normalized ratio (INR) results was completed, and TTR was calculated. Comparison of patients with TTR greater than 60% to those less than 60% was completed using chi-square analysis. Results: Of 43 patients with warfarin therapy managed by the nomogram, the mean TTR was 55.2% (calculated by fraction method) or 61.2% (calculated by Rosendaal method). More than half of the patients (63.5%) had moderate to good control, defined as TTR greater than 60%. Female sex, liver disease, or history of substance use and more medication holds were associated with lower TTR. Limitations: Small sample size and retrospective nature of review. Conclusions: The results of this review supports the use of an electronic, nursing-led nomogram for the maintenance management of warfarin therapy in stable patients treated with hemodialysis, as use results in TTR greater than 60% for more than half of patients.

Abstract Background The dynamic changes and stability of blood biomarkers over time and after treatment are not well known. In this study, we describe changes in 12 centrally quantified known and novel cardiovascular biomarkers, prior to and 3 months after ablation for atrial fibrillation (AF). Purpose In patients enrolled in the AXAFA-AFNET5 trial, we 1) characterised changes in 12 biomarker levels pre and post-ablation, 2) ascertained if biomarker changes are consistent between males and females, and 3) identified biomarkers which predict recurrent AF post-ablation. Methods and results Of the 674 patients who were recruited and randomised, 633 received the study drug and underwent ablation. Peripheral blood samples were available for 488 patients at baseline and 434 at 3 months follow-up (median age [Q1, Q3] 64 [58, 70] years; 34% female). Between baseline (BL) and follow-up (FU), paired comparisons revealed that 3 biomarkers decreased, ANG2 (median [Q1, Q3] BL 2.185 [1.711, 3.115], FU 1.827 [1.457, 2.297] ng/mL, p<0.001), BMP10 (BL 2.056 [1.810, 2.380], FU 1.986 [1.757, 2.260] ng/mL, p<0.001), and NTproBNP (BL 2.219 [0.858, 5.731] per 100pg/mL, p<0.001), while 1 biomarker increased, FABP3 (BL 2.911 [2.425, 3.508], FU 2.911 [2.462, 3.521], p=0.005). The remaining 8 biomarkers remained unchanged. Significant differences in ANG2, BMP10, NTproBNP and FABP3 were driven by patients who remained arrhythmia free at follow-up whereas biomarker levels remained unchanged in 121 patients who experienced recurrent AF (39%; Figure). Change scores were mainly consistent between males and females, however, CRP decreased significantly more in females. Recurrent AF episodes were not different between males and females (p=0.319). Cox proportional hazards model assessed the relationship of individual biomarkers at baseline for predicting recurrent AF. Elevated ANG2 (hazard ratio, HR per ng/mL [95% confidence interval] 1.214 [1.113, 1.325]), BMP10 (HR per ng/mL 1.516 [1.039, 2.214]), and NTproBNP (HR per 100 pg/mL 1.050 [1.025, 1.076]) significantly predicted increased risk for recurrent AF, after adjustment for age, sex, body mass index, hypertension, diabetes, chronic obstructive pulmonary disease, stroke, heart failure, ablation type (PVI, PVI and other, other), ablation energy (radiofrequency, cryoablation, other), and treatment arm. Conclusion In this study, most cardiovascular biomarkers are unchanged after ablation for AF, however, ANG2, BMP10, and NTproBNP decreased at follow-up. These effects are driven by patients who remained arrhythmia free and could potentially reflect improvement in vascular (ANG2), endothelial (BMP10), and myocardial load (NTproBNP) parameters post-ablation. This outcome corresponds with the observation that elevated levels of these biomarkers at baseline predict recurrent AF at 3 months. Both males and females demonstrate similar changes in biomarker profiles and benefit equally from ablation for AF.

Introduction: Clinicians are hesitant to prescribe oral anticoagulants to older adults with atrial fibrillation (AF) due to concerns over bleeding risk. Hypothesis: As many data on bleeding events are from trials of rigorously selected patients, we hypothesized that major bleeding events (requiring hospitalization) would be more common than previously reported. Methods: We created a retrospective cohort of 31,951 Veterans with AF aged ≥75 years who were new referrals to VA anticoagulation clinics (warfarin) from 1/1/02 - 12/31/12. Patients with comorbid conditions requiring warfarin (e.g. pulmonary embolus) were excluded. Data were extracted from the VA electronic medical record and linked with Medicare claims data for subsequent hospitalizations. The primary outcome was any hospitalization for bleeding. We identified bleeding subtypes by source, and compared characteristics of patients with and without bleeding hospitalizations. Results: Mean population age was 81.1 years, 98.1% were male, and 8.4% were nonwhite. Over a median follow-up period of 2.62 years, 7288 patients (22.8%) were hospitalized for bleeding. There were 12,004 total bleeding events; overall, 980 (13.4%) patients experienced multiple events. The most common bleeding sources (first event) were gastrointestinal (50.8%), genitourinary (21.6%), and intracranial (9.4%) (Figure). The median time to first bleeding event was 1.59 years. Patients hospitalized for bleeding were more likely to have coronary disease (48.4% vs. 40.9%, P<0.01); COPD (28.4% vs. 24.7%, P<0.01); chronic kidney disease (17.8% vs. 16.0%, P<0.01); CHF (34.7% vs. 29.5%, P<0.01), and labile INR (63.3% vs. 53.7%, P<0.01). The rate of hospitalization for stroke over the same time period was 5.0%. Conclusions: After initiating warfarin, over one in five older Veterans are hospitalized for bleeding, most commonly from a gastrointestinal source. Comorbidity burden and labile INR place these patients at increased risk.

Abstract Aims A J-shaped association of cardiovascular events to achieved systolic (SBP) and diastolic (DBP) blood pressure was shown in high-risk patients. This association on oral anticoagulation is unknown. This analysis from RELY assessed the risks of death, stroke or systemic emboli, and bleeding according to mean achieved SBP and DBP in atrial fibrillation on oral anticoagulation. Methods and results RE-LY patients were followed for 2 years and recruited between 22 December 2005 until 15 December 2007. 18.113 patients were randomized in 951 centres in 54 countries and 18,107 patients with complete blood pressure (BP) data were analysed with a median follow-up of 2.0 years and a complete follow-up in 99.9%. The association between achieved mean SBP and DBP on all-cause death, stroke and systemic embolic events (SSE), major, and any bleeding were explored. On treatment, SBP &gt;140 mmHg and &lt;120 mmHg was associated with all-cause death compared with SBP 120–130 mmHg (reference). For SSE, risk was unchanged at SBP &lt;110 mmHg but increased at 140–160 mmHg (adjusted hazard ratio (HR) 1.81; 1.40–2.33) and SBP ≥160 mmHg (HR 3.35; 2.09–5.36). Major bleeding events were also increased at &lt;110 mmHg and at 110 to &lt;120 mmHg. Interestingly, there was no increased risk of major bleeding at SBP &gt;130 mmHg. Similar patterns were observed for DBP with an increased risk at &lt;70 mmHg (HR 1.55; 1.35–1.78) and &gt;90 mmHg (HR 1.88; 1.43–2.46) for all-cause death compared to 70 to &lt;80 mmHg (reference). Risk for any bleeding was increased at low DBP &lt;70 mmHg (HR 1.46; 1.37–1.56) at DBP 80 to &lt;90 mmHg (HR 1.13; 1.06–1.31) without increased risk at higher achieved DBP. Dabigatran 150 mg twice daily showed an advantage in all patients for all-cause death and SSE and there was an advantage for 110 mg dabigatran twice daily for major bleeding and any bleeding irrespective of SBP or DBP achieved. Similar results were obtained for baseline BP, time-updated BP, and BP as time-varying covariate. Conclusion Low achieved SBP associates with increased risk of death, SSE, and bleeding in patients with atrial fibrillation on oral anticoagulation. Major bleeding events did not occur at higher BP. Low BP might identify high-risk patients not only for death but also for high bleeding risks. Clinical trial registration  ClinicalTrials.gov—Identifier: NCT00262600.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction The ESC-EHRA EORP AF General Long-Term Registry provides a contemporary snapshot of European atrial fibrillation (AF) patients’ characteristics and management. Aims: We present data about the final 2-years follow-up observation of AF patients enrolled in the ESC-EHRA EORP AF General Long-Term Registry. Methods A contemporary evaluation of residual risk of adverse outcomes in a cohort of largely anticoagulated AF patients according to the baseline thromboembolic and bleeding risk, defined according to CHA2DS2-VASc and HAS-BLED scores. We determined cardiovascular (CV) events, CV death and all-cause death as outcomes. Results Among the original 11069 patients enrolled, 8409 (76.0%) patients had available follow-up status at the end of the 2-years follow-up. Patients age, female sex and most comorbidities were progressively more prevalent across the spectrum of thromboembolic and bleeding risk. Data on adverse outcomes were available for 10087 (91.1%), over the 2-year observation period. Outcome rates were progressively higher across CHA2DS2-VASc and HAS-BLED scores (all p &lt; 0.0001). A fully adjusted Cox multivariable regression analysis, adjusted for clinical covariates selected by a univariate procedure and not included in the scores, showed that increasing baseline CHA2DS2-VASc score was associated with an higher risk for CV events (hazard ratio [HR]: 1.25, 95% confidence interval [CI]: 1.21-1.30), CV death (HR: 1.31, 95%CI: 1.25-1.38) and all-cause death (HR: 1.30, 95%CI: 1.25-1.36). Similarly, increasing baseline HAS-BLED score was associated with an increased risk for all 3 outcomes (HR: 1.21, 95%CI: 1.13-1.28; HR: 1.24, 95%CI: 1.14-1.34; HR: 1.22, 95%CI: 1.14-1.31, respectively). An association with a progressively higher risk was found for all outcomes across the spectrum of thromboembolic and bleeding risk [Figure]. Both CHA2DS2-VASc and HAS-BLED scores showed a modest to good predictive ability for cardiovascular (CV) events, CV death and all-cause death, in terms of c-index and 95% CI[0.66 (0.64-0.68) and 0.62 (0.61-0.64), 0.70 (0.68-0.72) and 0.65 (0.63-0.67), 0.69 (0.68-0.71) and 0.64 (0.63-0.66) for CHA2DS2-VASc and HAS-BLED for each outcome respectively. Conclusions In this large contemporary European-wide cohort of AF patients, both baseline thromboembolic and bleeding risks were associated to an increased risk of major clinical outcomes. Both scores are reflective of high risk clinical states, and are predictive of major adverse outcomes even in a large cohort of largely anticoagulated patients with a lower residual risk of adverse outcomes.

Abstract Background In patients with acute myocardial infarction (AMI), history of atrial fibrillation (AF) and new onset AF during the early phase may be associated with a worse prognosis. Whether both conditions are associated with a similar risk of stroke and should be similarly managed is a matter of debate. Methods Based on the administrative hospital-discharge database, we collected information for all patients treated with AMI between 2010 and 2019 in France. The adverse outcomes were investigated during follow-up. Results Among 797,212 patients with STEMI or NSTEMI, 146,922 (18.4%) had history of AF, and 11,824 (1.5%) had new AF diagnosed between day 1 and day 30 after AMI. Patients with new AF were older and had more comorbidities than those with no AF but were younger and had less comorbidities than those with history of AF. Both groups with history of AF or new AF had less frequent STEMI and anterior MI, less frequent use of percutaneous coronary intervention but more frequent HF at the acute phase than patients with no AF. During follow-up (mean [SD] 1.8 [2.4] years, median [interquartile range] 0.7 [0.1–3.1] years), 163,845 deaths and 20,168 ischemic strokes were recorded. Using Cox multivariable analysis, compared to patients with no AF, history of AF was associated with a higher risk of death during follow-up (adjusted hazard ratio HR 1.06 95% CI 1.05–1.08) while this was not the case for patients with new AF (adjusted HR 0.98 95% CI 0.95–1.02). By contrast, both history of AF and new AF were associated with a higher risk of ischemic stroke during follow-up compared to patients with no AF: adjusted hazard ratio HR 1.29 95% CI 1.25–1.34 for history of AF, adjusted HR 1.72 95% CI 1.59–1.85 for new AF. New AF was associated with a higher risk of ischemic stroke than history of AF (adjusted HR 1.38 95% CI 1.27–1.49). Conclusion In a large and systematic nationwide analysis, AF first recorded in the first 30 days after AMI was associated with an increased risk of ischemic stroke. Specific management should be considered in order to improve outcomes in these patients after AMI. Funding Acknowledgement Type of funding source: None
