Abstract Background High plasma B-Type natriuretic peptide (BNP) level is associated with cardiac events or stroke in patients with atrial fibrillation (AF). However, it is still unknown whether BNP predicts worse clinical outcomes after catheter ablation ofAF. Purpose We aimed to see if plasma BNP level is associated with major adverse cardiac and cerebrovascular events (MACCE) after catheter ablation of AF. Methods We retrospectively analyzed 1,853 participants (73.1% men, mean age 63.3±10.3 years, 60.7% paroxysmal AF) who received first catheter ablation of AF with pre-ablation plasma BNP level measurement and completed follow-up more than 3 months after the procedure from AF Frontier Ablation Registry, a multicenter cohort study in Japan. We evaluated an association between plasma BNP level before catheter ablation and first MACCE in cox-regression hazard models adjusted for known risk factors. MACCE were defined as stroke/transient ischemic attack (TIA), cardiovascular events or all-cause death. Results The mean plasma BNP level was 120.2±3.7 pg/mL. During a mean follow-up period of 21.9 months, 57 patients (3.1%) suffered MACCE (ischemic stroke 8 [14.0%], hemorrhagic stroke 5 [8.8%], TIA 5 [8.8%], hospitalization for heart failure 11 [19.2%], acute coronary syndrome 9 [15.8%], hospitalization for other cardiovascular events 8 [14.0%] and all-cause death 11 [19.2%]). Plasma BNP level of patients with MACCE were significantly higher than those without MACCE (291.7±47.0 vs 114.7±3.42 pg/mL, P<0.001). Multivariate analysis revealed that plasma BNP level (hazard ratio [HR] per 10 pg/mL increase 1.014; 95% confidence interval [CI] 1.005–1.023; P=0.001), baseline age (HR 1.052; 95% CI 1.022–1.084; P=0.001), heart failure (HR 2.698; 95% CI 1.512–4.815; P=0.001), old myocardial infarction (HR 3.593; 95% CI 1.675–7.708; P=0.001) and non-ischemic cardiomyopathy (HR 2.676; 95% CI 1.337 - 5.355; P=0.005) were independently associated with MACCE. At receiver-operating characteristic curve analysis, plasma BNP level before catheter ablation ≥162.7 pg/mL was the best threshold to predict MACCE (area under the curve: 0.71). Kaplan-Meier curve analysis (Figure) showed that the cumulative incidence of MACCE was significantly higher in patients with a BNP ≥162.7 pg/mL than in those with a BNP below 162.7 pg/mL (HR 4.85; 95% CI 2.86–8.21; P<0.001). Conclusions Elevation of plasma BNP level was independently related to the increased risk of MACCE after catheter ablation ofAF. Funding Acknowledgement Type of funding source: Private company.

Abstract Background Recent observational studies have suggested that catheter ablation for atrial fibrillation (AF) is significantly associated with reduced risk for stroke, cardiovascular events and all-cause death. However, little is known whether late recurrence of AF after catheter ablation is associated with worse clinical outcomes. Purpose We aimed to clarify whether late recurrence of AF after catheter ablation is associated with major adverse cardiac and cerebrovascular events (MACCE). Methods We retrospectively investigated 2,737 participants (74.4% men, mean age 63.4±10.3 years, 62.7% paroxysmal AF) who received first catheter ablation for AF and completed follow-up more than 3 months after the procedure from AF Frontier Ablation Registry, a multicenter cohort study in Japan. We evaluated an association between late recurrence of AF after catheter ablation and first MACCE in cox-regression hazard models adjusted for known risk factors. MACCE were defined as stroke/transient ischemic attack (TIA), cardiovascular events or all-cause death. Late recurrence was defined as AF relapse more than 3 months after the procedure. Results During a mean follow-up period of 25.2 months, 2,070 patients (75.6%) were free from AF after catheter ablation and 122 patients (4.5%) had MACCE (ischemic stroke 18 [14.8%], hemorrhagic stroke 16 [13.1%], TIA 7 [5.7%], hospitalization for heart failure 19 [15.6%], acute coronary syndrome 19 [15.6%], hospitalization for other cardiovascular events 24 [20%] and all-cause death 19 [15.6%]). The MACCE occurred significantly more frequently in the recurrence group than in non-recurrence group (7.5% vs. 3.5%; hazard ratio [HR] 1.85; 95% confidence interval [CI] 1.28–2.65; P=0.001) (Figure). Multivariate analysis revealed that baseline age (HR 1.05; 95% CI 1.03–1.08; P<0.001), heart failure (HR 1.76; 95% CI 1.17–2.66; P=0.007), old myocardial infarction (HR 4.49; 95% CI 2.59–7.81; P<0.001), non-ischemic cardiomyopathy (HR 2.56; 95% CI 1.47–4.46; P=0.001), left atrial diameter (HR 1.22 per 5-mm increase; 95% CI, 1.06–1.41; P=0.006) and recurrence of AF (HR 1.69; 95% CI 1.17–2.44; P=0.005) were independently associated with the incidence of MACCE after catheter ablation. Conclusion In the Japanese multicenter cohort of AF ablation, late recurrence of AF was independently associated with increased MACCE, suggesting the significance of sinus rhythm maintenance by catheter ablation.

Abstract Background New-onset atrial fibrillation (NOAF) complicating acute myocardial infarction (AMI) has been associated with poor survival, but the clinical implication of NOAF on subsequent heart failure (HF) is still not well studied. We aimed to investigate the relationship between NOAF following AMI and HF hospitalization. Methods This retrospective cohort study was conducted between February 2014 and March 2018, using data from the New-Onset Atrial Fibrillation Complicating Acute Myocardial Infarction in ShangHai registry, where all participants did not have a documented AF history. Patients with AMI who discharged alive and had complete echocardiography and follow-up data were analyzed. The primary outcome was HF hospitalization, which was defined as a minimum of an overnight hospital stay of a participant who presented with symptoms and signs of HF or received intravenous diuretics. Results A total of 2075 patients were included, of whom 228 developed NOAF during the index AMI hospitalization. During up to 5 years of follow-up (median: 2.7 years), 205 patients (9.9%) experienced HF hospitalization and 220 patients (10.6%) died. The incidence rate of HF hospitalization among patients with NOAF was 18.4% per year compared with 2.8% per year for those with sinus rhythm. After adjustment for confounders, NOAF was significantly associated with HF hospitalization (hazard ratio [HR]: 3.14, 95% confidence interval [CI]: 2.30–4.28; p<0.001). Consistent result was observed after accounting for the competing risk of all-cause death (subdistribution HR: 3.06, 95% CI: 2.18–4.30; p<0.001) or performing a propensity score adjusted multivariable model (HR: 3.28, 95% CI: 2.39–4.50; p<0.001). Furthermore, the risk of HF hospitalization was significantly higher in patients with persistent NOAF (HR: 5.81; 95% CI: 3.59–9.41) compared with that in those with transient NOAF (HR: 2.61; 95% CI: 1.84–3.70; p interaction = 0.008). Conclusion NOAF complicating AMI is strongly associated with an increased long-term risk of heart.

Abstract Background Catheter ablation improves clinical outcomes in symptomatic atrial fibrillation (AF) patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, the role of catheter ablation in HF patients with a preserved ejection fraction (HFpEF) is less clear. Purpose To determine the efficacy of catheter ablation of AF in patients with HFpEF relative to those with HFrEF. Methods We performed an extensive literature search and systematic review of studies that compared AF recurrence at one year after catheter ablation of AF in patients with HFpEF versus those with HFrEF. Risk ratio (RR) 95% confidence intervals were measured using the Mantel-Haenszel method for dichotomous variables, where a RR<1.0 favors the HFpEF group. Results Four studies with a total of 563 patients were included, of which 312 had HFpEF and 251 had HFrEF. All patients included were undergoing first time catheter ablation of AF. Patients with HFpEF experienced similar recurrence of AF one year after ablation on or off antiarrhythmic drugs compared to those with HFrEF (RR 0.87; 95% CI 0.69–1.10, p=0.24), as shown in Figure 1. Recurrence of AF was assessed with electrocardiography, Holter monitoring, and/or event monitoring at scheduled follow-up visits and final follow-up. Conclusion Based on the results of this meta-analysis, catheter ablation of AF in patients with HFpEF appears as efficacious in maintaining sinus rhythm as in those with HFrEF.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction There is some evidence suggesting that exaggerated hypertensive response to exercise (HRE) may be associated with higher risk of future cardiovascular events, however the relationship between systolic blood pressure (SPB) during exercise test and stroke is not fully understood. Purpose To evaluate the ability to predict the risk of stroke in patients with HRE in exercise test. Methods Single-center retrospective study of consecutive patients submitted to exercise test from 2012 to 2015 with HRE to stress test. HRE was defined as a peak systolic blood pressure (PSBP) > 210 mmHg in men and > 190 mmHg in women, or a rise of the SBP of 60 mmHg in men or 50 mmHg in women or as a diastolic blood pressure > 90 mmHg or a rise of 10 mmHg. Patient’s demographics, baseline clinical characteristics, vital signs during the stress test and the occurrence of stroke during follow-up were analysed Results We included 458 patients with HRE (76% men, 57.5 ± 10.83 years). The most frequent comorbidities were hypertension (83%), dyslipidaemia (61%), previously known coronary disease (32%), diabetes (28%) and smoking (38%). Atrial fibrillation was present in 5.9% of patients. During a mean follow-up of 60 ± 2 months, the incidence of stroke was 2.1% (n = 8), all with ischemic origin. Considering the parameters analysed on exercise test, only PSBP demonstrated to be an independent predictor of stroke (HR 1.042, CI95% 1.002-1.084, p = 0.039,) with moderate ability to predict stroke (AUC 0.735, p = 0.0016) with a most discriminatory value of 203 mmHg (sensibility 56%, specify 67%). Regarding baseline characteristics, after age, sex and comorbidities adjustment, previously controlled hypertension was found to be an independent protective factor of stroke (OR 4.247, CI 95% 0.05-0.9, p = 0.036) and atrial fibrillation was an independent predictor of stroke occurrence (HR 8.1, CI95% 1.4-46.9, p = 0.018). Atrial fibrillation was also associated with hospitalization of cardiovascular cause and major cardiovascular events occurrence (mortality, coronary syndrome and stroke). Baseline SBP was associated with atrial fibrillation development (p = 0.008). Conclusion According to our results, PSBP during exercise test is an independent predictor of stroke occurrence and should be considered as a potencial additional tool to predict stroke occurrence, particularly in high risk patients. The identification of diagnosed hypertension as a protective factor of stroke may be explained by the cardioprotective effect of antihypertensive drugs.

Background: Atrial fibrillation (AF) patients are likely to have concomitant coronary artery disease (CAD). A new strategy of antithrombotic therapy in AF patients with stable CAD was demonstrated in recent randomized clinical trials. Now that antithrombotic therapy for AF patients with CAD has reached a major turning point, it is important to know the prognostic factors in those patients. Purpose: In this study, we investigated clinical characteristics, cardiovascular events and prognostic factors in AF patients with CAD. Methods: The Fushimi AF Registry, a community-based prospective survey, was designed to enroll all of the AF patients who visited the participating medical institutions in Fushimi-ku, Kyoto, Japan. Follow up data including prescription status were available in 4,441 patients from March 2011 to November 2019. Of 4,441 patients, 645 patients had a history of CAD at enrollment. Results: The mean age was 76.4±8.6 and 65.9% were male. Averages of CHA 2 DS 2 -VASc score and HAS-BLED score were 4.41 and 2.35, respectively. Oral anticoagulant (OAC) was prescribed in 52.9% of those patients and antiplatelet drug (APD) was prescribed in 70.4%. The combination of OAC and APD was prescribed in 36.0%. During follow-up period (median 1,495 days), cardiac death occurred in 51 patients, composite of cardiac death, myocardial infarction (MI) and stroke in 136, and major bleeding in 77 (1.8, 5.1 and 2.9 per 100 person-years, respectively). In multivariate analysis, factors associated with composite of cardiac death, MI and stroke in AF patients with CAD were low body weight (<=50kg) (hazard ratio [95% confidence interval]; 1.62 [1.07-2.47]), previous stroke (1.69 [1.13-2.52]), heart failure (1.47 [1.02-2.11]), hypertension (0.60 [0.41-0.87]) and diabetes mellitus (1.62 [1.13-2.32]). Furthermore, factors associated with major bleeding in AF patients with CAD were anemia (male: hemoglobin<12 g/dl, female: hemoglobin<11 g/dl) (1.82 [1.09-3.04]) and thrombocytopenia (<150,000 /μL) (3.02 [1.29-7.03]). Conclusion: In Japanese AF patients with CAD, low body weight, previous stroke, heart failure, hypertension and diabetes mellitus were associated with cardiovascular events, and anemia and thrombocytopenia were associated with major bleeding.

Background: Heart failure (HF) is the leading cause of death in patients with atrial fibrillation (AF). Radiofrequency catheter ablation (RFCA) of AF is effective for maintaining sinus rhythm though its impact on heart failure still remains controversial. Purpose: We sought to elucidate whether AF recurrence following RFCA was associated with subsequent HF hospitalizations. Methods: We conducted a large-scale, prospective, multicenter, observational study. A total of 4931 consecutive patients who underwent an initial RFCA for AF with longer than 1-year of follow-up in 26 centers were enrolled (average age, 64±10 years; non-paroxysmal AF, 35.7%). The median follow-up duration was 2.9 years. The primary endpoint was an HF hospitalization more than 1-year after the index RFCA. We compared the patients without AF recurrences (group A) to those with AF recurrences within 1-year post RFCA (group B). Results: The 1-year cumulative incidence of AF recurrences after a single procedure was 30.7% (group A=3418, group B=1513 patients). Group B had a lower body mass index (group A vs. group B,24.1±3.6 vs. 23.8±3.4 kg/m 2 , p=0.014), longer history of AF (1.9 vs. 3.1 years, p<0.0001), higher prevalence of non-paroxysmal AF (32.1% vs. 33.9%, p<0.0001), and valvular heart disease (5.9% vs. 7.8%, p=0.013). They also had a lower ejection fraction (63.7±9.4% vs. 62.8±9.6%, p=0.0043) and larger left atrial dimeter (39.7±6.6 vs. 40.6±7.0 mm, p<0.0001) on echocardiography. Hospitalizations for HF were observed in 57 patients (1.14%) more than 1-year after the RFCA and were significantly higher in group B than group A (group A vs. group B, 0.91% vs 1.72%, log-rank p=0.019). Conclusions: Among AF patients receiving RFCA, those with AF recurrences were at a greater risk of subsequent heart failure hospitalizations than those without AF recurrences. Recognition that AF recurrence following RFCA is a risk factor for a subsequent HF-related hospitalization is appropriate in clinical practice.

Introduction: The impact of catheter ablation for atrial fibrillation (AF) on cardiovascular events and mortality is controversial. We investigated the impact of sinus rhythm maintenance on major adverse cardiac and cerebrovascular events after AF ablation from a Japanese multicenter cohort of AF ablation. Methods and Results: We investigated 2737 consecutive patients (25.6% female, mean age 63.4 ± 10.3 years) who underwent a first catheter ablation for AF from the Atrial Fibrillation registry to Follow the long-teRm Outcomes and use of aNTIcoagulants aftER Ablation (AF Frontier Ablation Registry). The primary endpoint was a composite of stroke, transient ischemic attack, cardiovascular events, and all-cause death. During a mean follow-up of 25.2 months, 2070 (75.6%) patients were free from AF after catheter ablation, and the primary composite endpoint occurred in 122 (4.5%) patients. The AF nonrecurrence group had a significantly lower incidence of the primary endpoint (1.7 per 100 person-years) compared with the AF recurrence group (3.2 per 100 person-years; P = 0.001). The multivariate analysis revealed that freedom from AF (hazard ratio 0.57; 95% confidence interval 0.39–0.83; P = 0.003) was independently associated with the incidence of the composite event.¬¬ Conclusion: In the multicenter cohort of AF ablation, sinus rhythm maintenance after catheter ablation was independently associated with lower rates of major adverse cardiac and cerebrovascular events.

Abstract Background Atrial fibrillation (AF) is associated with increased risks of stroke and heart failure. AF risk prediction can facilitate the efficient deployment of diagnosis or interventions to prevent AF. Purpose We sought to assess the combination prediction value of Holter electrocardiogram (Holter ECG) and the CHARGE-AF score (Cohorts for Aging and Research in Genomic Epidemiology-AF) for the new-onset of AF in a single center study. We also investigated the association between clinical findings and the new-onset of cerebral cardiovascular events. Methods From January 2008 and May 2014, 1246 patients with aged≥20 undergoing Holter ECG for palpitations, dizziness, or syncope were recruited. Among them, 350 patients were enrolled in this study after exclusion of 1) AF history at the time of inspection or before, 2) post cardiac device implantation, 3) follow-up duration &lt;1 year, and 4) no 12-lead ECG records within 6 months around Holter ECG. Results During the 5.9-year follow-up, 40 patients (11.4%) developed AF incidence. Multivariate cox regression analysis revealed that CHARGE-AF score (hazard ratio [HR]: 1.59, 95% confidence interval (95% CI): 1.13–2.26, P&lt;0.01), BMI (HR: 0.91, 95% CI: 0.83–0.99, P=0.03), frequent supraventricular extrasystoles (SVEs) ≥1000 beats/day (HR: 4.87, 95% CI: 2.59–9.13, P&lt;0.001) and first-degree AV block (HR: 3.52, 95% CI: 1.63–7.61, P&lt;0.01) were significant independent predictors for newly AF. The area under the ROC curve (AUC) of the combination of the CHARGE-AF score and frequent SVEs (≥1000) was greater than the CHARGE-AF score alone (0.73, 95% CI: 0.64–0.82 vs 0.66, 95% CI: 0.56–0.75, respectively). On the ROC curve, the CHARGE-AF score of 12.9 was optimum cut-off value for newly AF. Patients with both the CHARGE-AF score≥12.9 and SVEs≥1000 developed AF at 129.0/1000 person-years, compared with those with the CHARGE-AF score&lt;12.9 and SVEs≥1000 (48.9), the CHARGE-AF score≥12.9 and SVEs&lt;1000 (40.0) and the CHARGE-AF score&lt;12.9 and SVEs&lt;1000 (7.4), respectively. In multivariate cox regression analysis, age, past history of congestive heart failure and myocardial infarction, and antihypertensive medication were significant predictors of cerebral cardiovascular events (n=43), all of which signifying the components of the CHARGE-AF score. The AUC of the combination of the CHARGE-AF score and frequent SVEs (≥1000) was not different from the CHARGE-AF score alone (0.73, 95% CI: 0.64–0.81 vs 0.73, 95% CI: 0.64–0.82, respectively). Conclusion CHARGE-AF score has higher predictive power of both the new incident AF and cerebral cardiovascular events. The combination of CHARGE-AF score and SVEs≥1000 beats/day in Holter ECG can demonstrate the additional effect of prediction ability for the new incident AF, but not for cerebral cardiovascular events.

Treatment of chronic heart failure (CHF) is very controversial. The issue of optimal doses of beta-blockers, ACE inhibitors, aldosterone receptor antagonists, statins in patients with CHF has not been conclusively addressed. Achieving the maximum tolerated doses of drugs, though related to reduced mortality, but is accompanied by an increase in adverse drug reactions. The aim. To present and discuss our own clinical and scientific data concerning the role of beta-blockers and inhibitors of the renin-angiotensin aldosterone system, diuretics, statins in the treatment of CHF patients and optimization of dosage schemes. Material and methods. The study included 88 patients with CHF of ischemic origin, with sinus rhythm, stage II AB, NYHA FC II–IV, 58 – with reduced LV EF (HFrEF) and 30 – with preserved LV EF (HFpEF). The mean age of patients was 69.18 ± 9.97 years, men 52 % (n = 46). The median follow-up of the CHF patients was 396 days, the maximum number of follow-up days was 1302. During the observation period, 14 endpoints were registered, which accounted for 15.91 % of events: 7 deaths (8.0 %), 2 strokes (2.3 %), 2 cases of acute coronary syndrome (2.3 %), 3 progressive heart failure cases (3.4 %). Kaplan–Mayer curves were drawn to assess survival rate, and the significance of difference between groups was calculated by the criteria of Gehan–Wilcoxon, Cox–Mantel and log-rank test. Risk factors were determined, and prognostic uni- and multi-variant Cox proportional hazards regression models were used. The cut-off values of quantitative risk factors were obtained by ROC analysis. Results. The increase in the relative risk of adverse cardiovascular events in the CHF patients regardless of LV EF was associated with a daily carvedilol dose of more than 25 mg (HR = 1.05; 95 % CI 1.009–1.093; P = 0.0171); eplerenone – more than 12.5 mg (HR = 1.073; 95 % CI 1.005–1.144; P = 0.034), torasemide – more than 5 mg (HR = 1.13; 95 % CI 1.021–1.255; P = 0.019); rosuvastatin – more than 10 mg (HR = 1.107; 95 % CI 1.007–1.203; P = 0.035), and the trend in using atorvastatin at a dose of less than 10 mg (HR = 1.05; 95 % CI 0.951–1.165; P = 0.327). The use of ramipril in a daily dose of less than 2.5 mg was accompanied by a trend towards the 22 % reduced relative risk of adverse cardiovascular events (HR = 0.78; 95 % CI 0.384–1.580; P = 0.491). Conclusions. Positive treatment outcomes in the CHF patients, regardless of the phenotype, were associated with low daily doses of ramipril (<2.5 mg), eplerenone/spironolactone (<12.5 mg), torasemide (<5.0 mg), rosuvastatin (<10.0 mg), but with high doses of atorvastatin (>10.0 mg).

Background Atrial fibrillation (AF) and renal failure coexist and interact. However, scarce data about association between renal function and clinical outcomes in patients undergoing catheter ablation for AF are available. We sought to evaluate long-term renal function and clinical outcomes after AF ablation. Methods We enrolled 791 non-dialysis patients undergoing catheter ablation for AF, and evaluated the incidence of worsening renal function (WRF) after the procedure, defined as >30% decline in estimate glomerular filtration rate. Results Mean follow-up duration was 5.1±2.5 years. Five hundreds and twenty-six patients (66.5%) were free from recurrent atrial arrhythmias without any antiarrhythmic drugs at the time of final follow-up. Cumulative incidence of WRF was 13.2% at 5-year after procedure, which was significantly higher in patients with recurrent AF compared to those without (21.6% versus 8.7%, P<0.001). In the multivariable analysis, recurrent AF was an independent risk factor for WRF (adjusted hazard ratio [HR] 1.89, 95% confidence interval 1.27–2.81, P = 0.002), along with congestive heart failure, diabetes, and eGFR <60 ml/min/1.73m2 at baseline. Patients with WRF had significantly higher 5-year incidences of all-cause death, cardiovascular death, heart failure hospitalization, ischemic stroke, and major bleeding compared to those without WRF. After adjustment of baseline differences in the multivariate Cox model, the excessive risks of WRF for all-cause death and heart failure hospitalization remained significant (adjusted HR 3.46, P = 0.002; adjusted HR 3.67, P<0.001). Conclusions In AF patients undergoing catheter ablation for AF, arrhythmia recurrence was associated with WRF during follow-up, which was a strong predictor of adverse clinical outcomes.
