ObjectivesNatriuretic peptides are an important prognostic marker in patients with heart failure (HF). However, little is known regarding their prognostic significance in patients with atrial fibrillation (AF) without HF and natriuretic peptides levels are underused in these patients in daily practice.MethodsThe Fushimi AF Registry is a community-based prospective survey of patients with AF in Fushimi-ku, Kyoto, Japan. We investigated patients with AF without HF (defined as prior HF hospitalisation, New York Heart Association functional class≥2 or left ventricular ejection fraction<40%) using the data of B-type natriuretic peptide (BNP, n=388) or N-terminal pro-B-type natriuretic peptide (NT-proBNP, n=771) at enrolment. BNPs were converted to NT-proBNP using a conversion formula. We divided the patients according to quartiles of NT-proBNP levels and compared the backgrounds and outcomes.ResultsOf 1159 patients (mean age: 72.1±10.2 years, median CHA2DS2-VASc score: 3 and oral anticoagulant (OAC) prescription: 671 (56%)), the median NT-proBNP level was 488 (IQR 169–1015) ng/L. Patients with high NT-proBNP levels were older, had higher CHA2DS2-VASc scores and had more OAC prescription (all p<0.001). Kaplan-Meier curves demonstrated that NT-proBNP levels were significantly associated with higher incidences of stroke/systemic embolism, all-cause death and HF hospitalisation during a median follow-up period of 5.0 years (log rank, all p<0.001). Multivariable Cox regression analyses revealed that NT-proBNP levels were an independent predictor of adverse outcomes even after adjustment by various confounders.ConclusionNT-proBNP levels are a significant prognostic marker for adverse outcomes in patients with AF without HF and may have clinical value.Trial registration numberUMIN000005834.

Background/Aims: Cyr61-cysteine-rich protein 61 (CCN1/CYR61) is a multifunctional matricellular protein involved in the regulation of fibrogenesis. Animal experiments have demonstrated that CCN1 can inhibit cardiac fibrosis in cardiac hypertrophy. However, no study has been conducted to assess the relation between serum CCN1 and prognosis of acute heart failure (AHF). Methods: We measured the serum CCN1 levels of 183 patients with AHF, and the patients were followed up for 6 months. The associations between CCN1 levels and some clinical covariates, especially left ventricular ejection fraction (LVEF), estimated glomerular filtration rate (eGFR), atrial fibrillation and age, were estimated. The AHF patients were followed up for 6 months. The endpoint was all-cause mortality. Kaplan-Meier curve analysis and multivariable Cox proportional hazards analysis were employed to evaluate the prognostic ability of CCN1. We used calibration, discrimination and reclassification to assess the mortality risk prediction of adding CCN1. Results: Serum CCN1 concentrations in AHF patients were significantly increased compared with those in individuals without AHF (237 pg/ml vs. 124.8 pg/ml, p< 0.001). CCN1 level was associated with the level of NT-proBNP (r=0.349, p< 0.001) and was not affected by LVEF, eGFR, age or atrial fibrillation in AHF patients. Importantly, Kaplan-Meier curve analysis illustrated that the AHF patients with serum CCN1 level > 260 pg/ ml had a lower survival rate (p< 0.001). Multivariate Cox hazard analysis suggests that CCN1 functions as an independent predictor of mortality for AHF patients (LgCCN1, hazard ratio 5.825, 95% confidence interval: 1.828-18.566, p=0.003). In addition, the inclusion of CCN1 in the model with NT-proBNP significantly improved the C-statistic for predicting death (0.758, p< 0.001). The integrated discrimination index was 0.019 (p< 0.001), and the net reclassification index increased significantly after addition of CCN1 (23.9%, p=0.0179). Conclusions: CCN1 is strongly predictive of 6-month mortality in patients with AHF, suggesting serum CCN1 as a promising candidate prognostic biomarker for AHF patients.

Background: Effective therapies for HFrEF usually reduce NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels, and it is important to establish whether new treatments are effective across the range of NT-proBNP. Methods: We evaluated both these questions in the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) trial. Patients in New York Heart Association functional class II to IV with a left ventricular ejection fraction ≤40% and a NT-proBNP level ≥600 pg/mL (≥600 ng/L; ≥400 pg/mL if hospitalized for HF within the previous 12 months or ≥900 pg/mL if atrial fibrillation/flutter) were eligible. The primary outcome was the composite of an episode of worsening HF or cardiovascular death. Results: Of the 4744 randomized patients, 4742 had an available baseline NT-proBNP measurement (median, 1437 pg/mL [interquartile range, 857–2650 pg/mL]). Compared with placebo, treatment with dapagliflozin significantly reduced NT-proBNP from baseline to 8 months (absolute least-squares mean reduction, −303 pg/mL [95% CI, −457 to −150 pg/mL]; geometric mean ratio, 0.92 [95% CI, 0.88–0.96]). Dapagliflozin reduced the risk of worsening HF or cardiovascular death, irrespective of baseline NT-proBNP quartile; the hazard ratio for dapagliflozin versus placebo, from lowest to highest quartile was 0.43 (95% CI, 0.27–0.67), 0.77 (0.56–1.04), 0.78 (0.60–1.01), and 0.78 (0.64–0.95); P for interaction=0.09. Consistent benefits were observed for all-cause mortality. Compared with placebo, dapagliflozin increased the proportion of patients with a meaningful improvement (≥5 points) in Kansas City Cardiomyopathy Questionnaire total symptom score ( P for interaction=0.99) and decreased the proportion with a deterioration ≥5 points ( P for interaction=0.87) across baseline NT-proBNP quartiles. Conclusions: In patients with HFrEF, dapagliflozin reduced NT-proBNP by 300 pg/mL after 8 months of treatment compared with placebo. In addition, dapagliflozin reduced the risk of worsening HF and death, and improved symptoms, across the spectrum of baseline NT-proBNP levels included in DAPA-HF.

Atrial fibrillation (AF) directly leads to a cognitive function decline regardless of the cerebrovascular fatal events, but it is unclear whether the sinus rhythm restoration and reducing the AF burden can reduce the rate of this decreasement. Data on the effect of radiofrequency ablation on patients’ cognitive functions are conflicting and need to be studied. The aim of the study was to evaluate the prognostic value of atrial fibrillation radiofrequency catheter ablation on cognitive functions in patients with chronic heart failure with preserved left ventricular ejection fraction. The impact of AF radiofrequency catheter ablation on cognitive function in 136 patients (mean age 59.7 ± 8.6 years) with chronic heart failure with preserved left ventricular ejection fraction and compared with 58 patients in the control group (58.2 ± 8.1 years), which did not perform ablation and continued the tactics of drug antiarrhythmic therapy was investigated. Cognitive function was assessed using the Montreal Cognitive Test (MoCA) at the enrollment stage and 2 years follow-up. Decreased cognitive function was defined as a MoCA test score < 26 points, cognitive impairment < 23 points. Two years after the intervention, there was a positive dynamics (baseline MoCA test — 25,1 ± 2,48, 2-year follow-up — 26,51 ± 2,33, p < 0,001) in the ablation group and negative in the control group (25,47 ± 2,85 and 24,57 ± 3,61, respectively, p < 0,001). Pre-ablation cognitive impairment was significantly associated with improved cognitive function 2 years after AF ablation according to polynomial regression analysis. The obtained data suggest a probable positive effect of AF radiofrequency ablation on cognitive functions in patients with preserved left ventricular ejection fraction.

Heart failure (HF) and atrial fibrillation (AF) are the most common cardiovascular conditions in clinical practice and frequently coexist. The number of patients with HF and AF is increasing every year.Aim. To analyze the effect of clinical course and management of HF and AF on the outcomes.Material and methods. The data of 1,003 patients from the first Russian register of patients with HF and AF (RIF-CHF) were analyzed. The endpoints included hospitalization due to decompensated HF, cardiovascular mortality, thromboembolic events, and major bleeding. Predictors of unfavorable outcomes were analyzed separately for patients with HF with preserved ejection fraction (AF+HFpEF), mid-range ejection fraction (AF+HFmrEF), and reduced ejection fraction (AF+HFrEF).Results. Among all patients with HF, 39% had HFpEF, 15% — HFmrEF, and 46% — HFrEF. A total of 57,2% of patients were rehospitalized due to decompensated HF within one year. Hospitalization risk was the highest for HFmrEF patients (66%, p=0,017). Reduced ejection fraction was associated with the increased risk of cardiovascular mortality (15,5% vs 5,4% in other groups, p<0,001) but not ischemic stroke (2,4% vs 3%, p=0,776). Patients with HFpEF had lower risk to achieve the composite endpoint (stroke+MI+cardiovascular death) as compared to patients with HFmrEF and HFrEF (12,7% vs 22% and 25,5%, p<0,001). Regression logistic analysis revealed that factors such as demographic characteristics, disease severity, and selected therapy had different effects on the risk of unfavorable outcomes depending on ejection fraction group.Conclusion. Each group of patients with different ejection fractions is characterized by its own pattern of factors associated with unfavorable outcomes. The demographic and clinical characteristics of patients with mid-range ejection fraction demonstrate that these patients need to be studied as a separate cohort.

Background: Even on optimal therapy, many patients with heart failure and atrial fibrillation experience cardiovascular complications. Additional treatments are needed to reduce these events, especially in patients with heart failure and preserved left ventricular ejection fraction (HFpEF). Methods: This prespecified subanalysis of the randomized EAST - AFNET 4 trial assessed the effect of systematic, early rhythm control therapy (ERC; using antiarrhythmic drugs or catheter ablation) compared to usual care (UC, allowing rhythm control therapy to improve symptoms) on the two primary outcomes of the trial and on selected secondary outcomes in patients with heart failure, defined as heart failure symptoms NYHA II-III or left ventricular ejection fraction [LVEF] <50%. Results: This analysis included 798 patients (300 (37.6%) female, median age 71.0 [64.0, 76.0] years, 785 with known LVEF). The majority of patients (n=442) had HFpEF (LVEF≥50%; mean LVEF 61% ± 6.3%), the others had heart failure with mid-range ejection fraction (n=211; LVEF40-49%; mean LVEF 44% ± 2.9%) or heart failure with reduced ejection fraction (n=132; LVEF<40%; mean LVEF 31% ± 5.5%). Over the 5.1-year median follow-up, the composite primary outcome of cardiovascular death, stroke or hospitalization for worsening of heart failure or for acute coronary syndrome occurred less often in patients randomized to ERC (94/396; 5.7 per 100 patient-years) compared with patients randomized to UC (130/402; 7.9 per 100 patient-years; hazard ratio 0.74 [0.56-0.97], p=0.03), not altered by heart failure status (interaction p-value=0.63). The primary safety outcome (death, stroke, or serious adverse events related to rhythm control therapy) occurred in 71/396 (17.9%) heart failure patients randomized to ERC and in 87/402 (21.6%) heart failure patients randomized to UC (hazard ratio 0.85 [0.62-1.17], p=0.33). LV ejection fraction improved in both groups (LVEF change at two years: ERC 5.3%±11.6%, UC 4.9%±11.6%, p=0.43). ERC also improved the composite outcome of death or hospitalization for worsening of heart failure. Conclusions: Rhythm control therapy conveys clinical benefit when initiated within one year of diagnosing atrial fibrillation in patients with signs or symptoms of heart failure.

Atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) are two cardiovascular conditions that often coexist. Overlapping symptoms, biomarker profile, and echocardiographic changes hinder the diagnosis of underlying HFpEF in patients with AF and suggest that both conditions might reflect similar remodelling processes in the heart. Purpose. To assess cardiac remodelling in AF patients with versus without concomitant HFpEF by transthoracic echocardiography, focusing on atrial dimension and strain. Methods. We selected 120 patients included in AF-RISK, a prospective, observational, multicentre study aiming to identify a risk profile to guide atrial fibrillation therapy study. Patients had paroxysmal AF diagnosed within three years before inclusion, had a left ventricular ejection fraction (LVEF) ≥50% and were in sinus rhythm at the moment of performing echocardiography and blood sampling. Patients were matched by nearest neighbour by age and sex with a 1:1 ratio and were classified into two groups: 1) AF with HFpEF (n = 60) and 2) AF without HFpEF (n = 60). The diagnosis of HFpEF was based on the 2016 ESC heart failure guidelines, including symptoms and signs of heart failure, N-terminal pro-B-type natriuretic peptide (NT-proBNP) ≥125pg/ml, and one of the following echocardiographic measures: left atrium volume index (LAVI) &gt;34ml/m2, left ventricular mass index ≥115g/m2 for men and ≥95g/m2 for women, average E/e’ ≥13cm/s and average e’ &lt;9cm/s. Measurements of reservoir, conduit and contraction strain of both atria were performed in apical four-chamber by echocardiography (GE, EchoPac BT12). Associations of clinical and echocardiographic characteristics were tested for collinearity by multivariable logistic regression analyses. LAVI, LV mass index and NT-proBNP were excluded from multivariable analysis since these markers were part of the HFpEF diagnostic criteria. Results. Patients with paroxysmal AF and concomitant HFpEF had more often hypertension (72% vs. 45%, P = 0.005), had more impaired strain phases of both the left and right atria (figure 1), had comparable LVEF and global longitudinal strain (GLS) (P = 0.168 and P = 0.212, respectively). In a model adjusted for the number of comorbidities and sex, LA contraction decrease was associated with presence of HFpEF (odds ratio per 1% LA contraction-percent was 0.94, 95% confidence interval 0.87–0.99, P = 0.042). LA contraction was not explained by LAVI in patients with concomitant HFpEF (Spearman’s rho= -0.07, P = 0.08). Conclusion. Our results show that atrial function may differentiate paroxysmal AF patients with HFpEF from those without HFpEF. In patients with paroxysmal AF, more impaired strain phases of the left and right atria were associated with concomitant HFpEF, whereas ventricular function, reflected by LVEF and GLS, did not differ.
