Abstract Funding Acknowledgements Type of funding sources: None. OnBehalf Portuguese Registry of Acute Coronary Syndromes Background Acute coronary syndrome (ACS) and atrial fibrillation (AF) are common diseases in developed countries and in some cases, the first episode of AF can occur during the ACS. A stressful event like an ACS can be a trigger for AF, being important to realize its impact and prognosis in the short and long term. Objective Evaluate the impact and prognosis of new-onset AF in ACS. Methods Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-4/09/2019. Patients were divided into two groups: A – patients without new-onset AF, and B – patients that presented new onset of AF. Were excluded patients without a previous cardiovascular history or clinical data during the admission and the follow-up period. Logistic regression was performed to assess if new-onset AF in ACS was a predictor of major adverse cardiac events and mortality. Kaplan-Meier test was performed to establish the survival rates and re-admission for one year of follow up. Results 9687 patients suffered ACS and had follow-up at 1 year, 9264 in group A (95.6%) and 423 in group B (4.4%). Both groups were similar regarding dyslipidemia, diabetes mellitus, previous coronary artery disease, multivessel disease after the cardiac catheterization. Group A had more smokers (28.2 vs 17.8%, p < 0.001) and left ventricular ejection fraction (LVEF) >50% (69.2 vs 45.1%, p < 0.001). On the other hand, group B was elderly (67 ± 14 vs 75 ± 12, p < 0.001), female (26.9 vs 34.0%, p < 0.001), arterial hypertension (70.5 vs 77.5%, p = 0.005), was more admitted directly to the cat lab (12.5 vs 17.7%, p = 0.002), ST-segment elevation myocardial infarction (40.2 vs 49.9%, p < 0.001), Killip-Kimball classification > I (12.8 vs 34.8%, p < 0.001) and hybrid revascularization (0.7 vs 2.4%, p = 0.002). Logistic regression revealed that new-onset of AF in ACS patients was a predictor of congestive heart failure (odds ratio (OR) 1.75, p < 0.001, confidence interval (CI) 1.47-2.09), cardiogenic shock (OR 3.08, p < 0.001, CI 2.37-4.01), sustained ventricular tachycardia (OR 2.29, p < 0.001, CI 1.61-3.25) and intrahospital mortality (OR 1.99, p < 0.001, CI 1.51-2.63). Nevertheless, new-onset of AF was not associated with re-infarction (p = 0.361), mechanical complications (p = 0.319), atrioventricular block (p = 0.574), stroke (p = 0.131) and cardiac arrest (p = 0.060) during the hospitalization for ACS. Mortality rates at one year of follow-up showed significant differences, p < 0.001, between the two groups (Figure 1). Similar results were found concerning re-admission for all causes, p = 0.021 (Figure 2), on the other causes, re-admission for cardiovascular causes do not reveal to be significant, p = 0.515. Conclusions New-onset of AF in ACS was a predictor of congestive heart failure, cardiogenic shock, sustained ventricular tachycardia and intrahospital mortality. AF was associated with higher mortality rates and re-admission for all causes at one year follow up.

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.

Abstract The heart rate regularization is crucial for proper treatment of patients with atrial fibrillation and congestive heart failure. The standard resynchronization can be applied, but in patients with narrow QRS this procedure is of no use. The aim of our study is to assess the efficacy of direct His-bundle pacing in patients with congestive heart failure and chronic atrial fibrillation using dual chamber ICD implanted for prevention of sudden cardiac death. Methods The study population included 78 patients with CHF and chronic AF: group A - 56 pts treated with direct His-bundle pacing using atrial port of dual chamber ICD and group B - 22 patients implanted with single chamber ICD as recommended by the guidelines. The patients in group B constituting clinical controls were derived from the Heart Failure Outpatients Clinic with established clinical status and pharmacotherapy. Results The demographic data, clinical characteristics and echocardiography measurements at baseline and during follow-up were presented in the table: Table 1 Group A Group B P value Age (years) 69.7±6.9 66.7±11.3 n.s. Sex (% of male sex) 84.0 86.4 n.s. Ventricular pacing (%) – 46.3±31.2 – His-bundle pacing (%) 81.7±9.2 – – pre post pre post pre vs. post LVEDD (mm) 66.9±4.9 59.9±4.7 64.8±8.0 64.7±8.1 <0.01 n.s. EF (%) 29.6±3.8 43.6±5.9 28.1±6.1 28.8±7.3 <0.01 n.s. NYHA class 2.7±0.6 1.4±0.6 2.5±0.6 2.0±0.2 <0.05 n.s. B-blocker dose (metoprolol equivalent dose) 104.6±41.6 214.3±82.6 78.3±56.6 103.1±49.2 <0.001 <0.05 During 12-months of follow-up the mean values of NYHA functional class, EF and LV dimensions did not change in group B but significantly improved in group A. The physiological His-bundle based pacing enabled optimal beta-blocker dosing. The studied groups had no tachyarrhythmia at baseline so the presumable atrial fibrillation-related harm depends on the rhythm irregularity. Conclusions His-bundle-based pacing in CHF-chronic AF patients contributes to significant echocardiographic and clinical improvement. Standard single-chamber ICD implantation in CHF-chronic AF patients yields only SCD prevention without influence on remodeling process. The CHF-patients with narrow QRS and chronic AF benefit from substantially higher beta-blockade which can be instituted in His-bundle pacing group.

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&lt;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&lt;0.001) or performing a propensity score adjusted multivariable model (HR: 3.28, 95% CI: 2.39–4.50; p&lt;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&lt;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 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&lt;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&lt;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.

Introduction: The randomized controlled VOLCANO trial demonstrated comparable 1-year rhythm outcomes between patients with and without ablation targeting low-voltage areas (LVAs) in addition to pulmonary vein isolation among paroxysmal atrial fibrillation (AF) patients with LVAs. To compare long-term AF/atrial tachycardia (AT) recurrence rates and types of recurrent-atrial-tachyarrhythmia between treatment cohorts during a > 2-year follow-up period. Methods: An extended-follow-up study of 402 patients enrolled in the VOLCANO trial with paroxysmal AF, divided into 4 groups based on the results of voltage mapping: Group A, no LVA (n=336); group B, LVA ablation (n=30); group C, LVA presence without ablation (n=32); and group D, incomplete voltage map (n=4). Results: At 25 (23, 31) months after the initial ablation, AF/AT recurrence rates were 19% in group A, 57% in group B, 59% in group C, and 100% in group D. Recurrence rates were higher in patients with LVAs than those without (group A vs. B+C, p<0.0001), and were comparable between those with and without LVA ablation (group B vs. C, p=0.83). Among patients who underwent repeat ablation, ATs were more frequently observed in patients with LVAs (Group B+C, 50% vs. A, 14%, p<0.0001). In addition, LVA ablation increased the incidence of AT development (group B, 71% vs. C, 32%, p<0.0001), especially biatrial tachycardia (20% vs. 0%, p=0.01). Conclusion: Patients with LVAs demonstrated poor long-term rhythm outcomes irrespective of LVA ablation. ATs were frequently observed in patients with LVAs, and LVA ablation might exacerbate iatrogenic ATs.

Abstract Background Type 2 diabetes (T2DM) portends adverse prognosis in patients with atrial fibrillation (AF). Whether T2DM independently increases the risk of incident heart failure (HF) in AF is uncertain. Also, HF phenotype developing in patients with vs. those without T2DM has not been characterised. Purpose In AF patients without a history of prior HF, we aimed to assess: 1) the impact of T2DM on the risk of new-onset HF; and 2) the association between T2DM and HF phenotype developing during the prospective follow-up. Methods We included diabetic and non-diabetic AF patients, without a history of HF. Baseline T2DM status was inferred from medical history, haemoglobin A1c levels and oral glucose tolerance test. Study outcome was the first hospital admission or emergency department treatment for new-onset HF during the prospective follow-up. The phenotype of new-onset HF was determined by echocardiographic exam performed following clinical stabilisation (at hospital discharge, or within a month after HF diagnosis). HF phenotype was defined as HFrEF (left ventricular ejection fraction [LVEF] <40%), HFmrEF (LVEF 40–49%) or HFpEF (LVEF≥50%). Cox regression analyses adjusted for age, sex, baseline LVEF, comorbidities, smoking status, alcohol intake, AF type (paroxysmal vs. non-paroxysmal) and T2DM treatment was used to analyse the association between T2DM and incident HF. Results Among 1,288 AF patients without prior HF (mean age: 62.1±12.7 years; 61% male), T2DM was present in 16.5%. Diabetic patients had higher mean baseline LVEF compared with nondiabetic patients (50.0±6.2% vs. 57.6±9.0%; P<0.001). During the median 5.5-year follow-up, new-onset HF occurred in 12.4% of patients (incidence rate, 2.9; 95% confidence interval [CI], 2.5–3.3 per 100 patient-years). Compared with non-diabetic patients, those with T2DM had a hazard ratio of 2.1 (95% CI, 1.6–2.8; P<0.001) for new-onset HF, independent of baseline LVEF or other factors. In addition, diabetic patients had a significantly greater decline in covariate-adjusted mean LVEF (−10.4%; 95% CI, −9.8% to −10.8%) at follow-up, compared with nondiabetic patients (−4.0%; 95% CI, −3.8% to −4.2%), P<0.001. The distribution of HF phenotypes at follow-up is presented in Figure. Among patients with T2DM, HFrEF (56.9%) was the most common phenotype of HF, whereas in patients without T2DM, HF mostly took the phenotype of HFpEF (75.0%). Conclusions T2DM is associated with an independent risk of new-onset HF in patients with AF and confers a greater decline in LVEF compared to individuals without T2DM. HFrEF was the most prevalent presenting phenotype of HF in AF patients with T2DM.

Abstract Background Atrial fibrillation (AF) is the most common sustained arrhythmia affecting humans. It is an electrical disturbance that leads to rapid, disorganized, and asynchronous contraction of the atrial muscle. In clinical practice, it accounts for approximately one-third of hospitalizations for cardiac rhythm disturbances. The incidence of AF increases from less than 0.1% per year in those under 40 years old to exceed 1.5% per year in women and 2% per year in men older than 80 years. Aim of the Work: to discuss the effect of variation in amiodarone use (including dosage and duration) on dysrhythmia recurrence in patients with new-onset AF in ICU. Patients and Methods This was a prospective observational study conducted over 6 months, 60 patients who fulfilled inclusion criteria were included in the study divided in two groups according to amiodarone dosage, each group is 30 patients: Group (A): received a loading dose of amiodarone followed by an infusion (1200mg amiodarone). Group (B): received a loading dose of amiodarone not followed by an infusion (300mg amiodarone). Results a significant positive correlation was observed between level of C-reactive protein (CRP) and the rate of AF recurrence. As regard effect of CRP on AF recurrence; in AF recurrent patients, mean is (191±77.3) with range from 15 to 352 which significantly differed from Non-recurrent AF patients, mean is (89±63) with range from 20 to 223 (p value &lt;0.001). AF recurrence was higher in group (B) than group (A),. In group (A) 8 patients had recurrent AF representing 26.7 % and in group (B) 19 patients had AF recurrence representing 63.3% (p value =0.004). Conclusion Patients with new-onset AF in (ICU) who are treated with amiodarone should receive a loading dose, immediately followed by an infusion.

Aim To evaluate the performance of two different flexible devices, the balloon-expandable BeGraft stent as on-label chEVAR use with the Endurant (Medtronic, Santa Rosa, USA) stent graft compared to the self-expandable off-label employment of Viabahn (Gore Flagstaff, Arizona, USA). Methods All patients treated for pararenal aortic pathologies between 2008 and 2017 using Endurant II (Medtronic, Santa Rosa, CA, USA) abdominal endograft in combination with Viabahn (Gore, Flagstaff, AZ, USA) or BeGraft (Bentley, Hechingen, Germany) at our institution were retrospectively analyzed. Patients were divided into two groups according to the employed chimney graft, namely Viabahn (group A) and BeGraft (group B). The primary endpoint was the incidence of type IA endoleak at one month and last follow-up. Secondary endpoints included reintervention rates, primary patency of the chimney graft, and need for additional placement of bare metal stents also known as relining. Results A total of 27 patients (mean age: 76 years) were treated with overall 47 chimney grafts. In particular, 11 patients received 21 Viabahn and 16 patients underwent placement of 26 BeGraft stents. Mean follow-up was 14.3 ± 9.0 months for group A and 13.0 ± 13.7 for group B, p = .451. The mean chimney graft length was 85.1 ± 38.9 mm for group A and 34.9 ± 9.8mm for group B ( p < .001). The oversizing rate at the proximal sealing zone was significantly higher in group B (Group A: 23.1 ± 16.5% vs. Group B: 33.6 ± 7.6%, p = .007). The primary patency rates were similar between groups ( p = .250). The subgroup analysis showed a significantly higher early (9–42.9% vs. 2–7.7%, p = .005) and at last CT follow-up (5–23.8% vs. 0–0.0%, p = .011) type IA endoleak, higher primary relining (14–66.7% vs. 5–19.2%, p = .001) and reintervention rates (5–23.8% vs. 0–0.0%; p = .011) for group A chimney stent grafts. Conclusions Both chEVAR combinations displayed similar patency rate, showing the BeGraft-Endurant composition less need for relining and fewer one-year type IA endoleak and reintervention rates in the subgroup analysis.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Several studies have concluded that smoking increases mortality in patients with coronary disease. On the other hand, a J-shaped dose-effect curve has been used to describe the relationship between alcohol and cardiovascular mortality. According to the majority of studies, a moderate intake of alcohol is associated with a decrease in mortality, while an excessive alcohol intake appears to increase mortality. Aim To evaluate the effect of smoking and excessive alcohol intake in hospital mortality and 1-year mortality in patients hospitalized due to acute coronary syndrome (ACS). Methods A single-centre retrospective study was conducted, with inclusion of all consecutive patients admitted in the Cardiology Department due to ACS. Follow-up started after hospital admission and ended upon hospital death, death within the following 12 months or 12 months after study entry. Patients were divided in two groups: smokers (Group-A) and non-smokers (Group-B), to analyse the effect of smoking in hospital mortality and 1-year mortality. To analyse the effect of excessive alcohol intake, patients were also divided in other two groups: Group-C (excessive drinkers) and Group-D (non-excessive drinkers). Statistical analysis was performed with SPSS and a p value &lt; 0.05 was considered statistically significant. Results 1120 patients (68.9% male, mean age 69.12 ± 12.67 years) were included in this study. 20.5% were smokers and 3.2% had a previous excessive alcohol intake. Between Group-A and Group-B, a statistically significant difference was observed in gender (93.1% male in Group-A vs 62.9% male in Group-B, p = 0.002), but not in age (p = 0.116). Hospital mortality rates in Group-A and Group-B were respectively 6.0% and 8.7% (p = 0.191) and 1-year mortality rates were 3.1% vs 5.1% (p = 0.239). Between Group-C and Group-D, a statistically significant difference was observed in gender (94.4% male in Group-C vs 69.8% male in Group-B, p &lt; 0.001), but not in age (p = 0.730). Hospital mortality rates in Group-C and Group-D were respectively 25% and 9.6% (p = 0.003) and 1-year mortality were 3.8% vs 6.6% (p = 0.577). Conclusions Smoking did not have a positive or negative effect in hospital mortality and 1-year mortality. However, excessive alcohol intake was associated with increased hospital mortality in this population.
