Abstract Background There is a long-standing and unresolved controversy over the effects of digoxin on mortality. Furthermore, there is scarce evidence comparing the use of digoxin to beta-blocker in the general population with atrial fibrillation (AF). In this study, we aimed to evaluate the effects of digoxin over beta-blocker therapy among patients with AF. Methods Patients from the EORP-AF General Long-Term Registry with AF who were treated with either digoxin or beta-blocker were included. All patients were over 18 years old and had documented evidence of AF within 12 months prior to enrolment. The outcomes of interest were all-cause mortality, cardiovascular (CV) mortality, non-CV mortality and number of patients with unplanned hospitalisation (total and AF-related). These were recorded until the last known follow-up available. Results Of 6377 patients, 549 (8.6%) and 5828 (91.4%) were treated with digoxin and beta-blockers, respectively. Patients in the digoxin group were older (73 vs. 71 years, p<0.001) with reduced renal function (eGFR 65.4 vs. 68.7 mL/min/1.73m2, p=0.002), and had (in general) greater burden of comorbidities in terms of chronic kidney disease, chronic obstructive pulmonary disease, heart failure, hypertension and peripheral artery disease. Nonetheless, the use of anticoagulation therapy was comparable between both groups (p=0.112). Over 24 months follow-up, there were 550 (8.6%) all-cause mortality and 1304 (23.6%) patients with unplanned emergency hospitalisation. Digoxin use was associated with increased all-cause mortality (hazard ratio [HR] 1.90 [95% CI, 1.48–2.44]), both from CV and non-CV causes (CV: HR 2.21 [95% CI, 1.49–3.26]); non-CV: HR 1.70 [95% CI, 1.04–2.79]). There was no statistical difference in terms of unplanned emergency hospitalisation (HR 0.99 [95% CI, 0.80–1.21]) and AF-related hospitalisation (HR 0.78 [95% CI, 0.58–1.06]) between both groups. Using multivariable cox regression analysis, digoxin compared to beta-blocker therapy was independently linked to increased all-cause mortality (HR 1.52 [95% CI, 1.11–2.09]) and CV mortality (HR 1.82 [95% CI, 1.11–2.97]), but was not related to non-CV mortality (HR 1.31 [95% CI, 0.71–2.41]), emergency hospitalisation (HR 0.91 [95% CI, 0.71–1.16]) or AF-related hospitalisation (HR 0.88 [95% CI, 0.62–1.24]), after adjustment for known risk factors. Conclusion We demonstrated that the use of digoxin was independently associated with excess all-cause mortality, driven by CV death, but was non-inferior to beta-blocker in terms of preventing unplanned emergency or AF-related hospitalisation, after accounting for important risk factors.

Abstract Background CHA2DS2-VASc score has been used as a surrogate marker for predicting outcomes beyond thromboembolic risk in patients with atrial fibrillation (AF). Likewise, cardiac troponin I (cTnI) is a predictor of mortality in AF. Purpose This study aimed to investigate the association of cTnI and CHA2DS2-VASc score with long-term prognosis in patients admitted to the emergency department with AF. Methods A retrospective cohort study conducted between January 2012 and December 2013, enrolling patients admitted to the emergency department with AF and having documented cTnI measurements. CHA2DS2-VASc score was estimated. Primary endpoint was 5-year all-cause mortality, readmission for heart failure (HF), readmission for myocardial infarction (MI) and the composite end point of major adverse cardiac events defined as death, readmission for HF or readmission for MI (MACE). Results A total of 578 patients with AF were studied, of whom 252 patients had elevated levels of cTnI (43.6%) and 334 patients had CHA2DS2-VASc score >3 (57.8%). Patients with elevated cTnI tended to be oldercompared with those who did not have cTnI elevation and were more frequently comorbid and of higher ischemic risk, including hypertension, prior MI, prior HF, chronic renal failure and peripheral artery disease. The overall median CHA2DS2-VASc score was higher in those with cTnI elevation compared to those patients elevated cTnI levels (4.2 vs 3.3 points, p<0.001). Main diagnoses at hospital discharge were tachyarrhythmia 30.3%, followed by heart failure 17.7%, respiratory infections 9.5% and acute coronary syndrome 7.3%. At 5-year follow-up, all-cause death was significantly higher for patients with cTnI elevation compared with those who did not have cTnI elevation (56.4% vs. 27%; logrank test p<0.001). Specifically, for readmissions for HF and readmissions for MI there were no differences in between patients with or without cTnI elevation. In addition, MACE was reached in 165 patients (65.5%) with cTnI elevation, compare to 126 patients (38.7%) without cTnI elevation (p<0.001). On multivariable Cox regression analysis, cTnI elevation was an independent predictor of all-cause death (hazard ratio, 1.67, 95% confidence interval [CI]: 1.24–2.26, p=0.001) and of MACE (hazard ratio 1.47, 95% confidence interval 1.15–1.88; P=0.002), but it did not reach statistical significance for readmissions for MI and readmissions for HF. CHA2DS2-VASc score was a predictor on univariate Cox regression analysis for each endpoint, but it did not reach significance on multivariable Cox regression analysis for any endpoint. Conclusions cTnI is independently associated with long-term all-cause mortality in patients attending the emergency department with AF. cTnI compared to CHA2DS2-VASc score is thus a biomarker with predictive capacity for mortality in late follow-up, conferring utility in the risk stratification of patients with atrial fibrillation.

ObjectiveIn order to avoid effects of referral bias, we assessed risk factors for disease-related mortality in a geographical cohort of patients with hypertrophic obstructive cardiomyopathy (HOCM), and any therapy effect on survival.MethodsDiagnostic databases in 10 hospitals in the West Götaland Region yielded 251 adult patients with HOCM (128 male, 123 female). Case notes were reviewed for clinical data and ECG and ultrasound findings. Beta-blockers were used in 71.3% of patients from diagnosis (median metoprolol-equivalent dose of 125 mg/day), and at latest follow-up in 86.1%; 121 patients had medical therapy alone, 88 short atrioventricular delay pacing and 42 surgical myectomy. Mean follow-up was 14.4±8.9 (mean±SD) years. Primary endpoint was disease-related death, and secondary endpoint heart failure deaths.ResultsThere were 65 primary endpoint events. Independent risk factors for disease-related death on multivariate Cox hazard regression were: female sex (p=0.005), age at diagnosis (p<0.001), outflow gradient ≥50 mm Hg at diagnosis (p=0.036) and at follow-up (p=0.001). Heart failure caused 62% of deaths, and sudden cardiac death 17%. Late independent predictors of heart failure death were: female sex (p=0.003), outflow gradient ≥50 mm Hg at latest follow-up (p=0.032), verapamil/diltiazem therapy (p=0.012) and coexisting hypertension (p=0.031), but not other comorbidities. Neither myectomy nor pacing modified survival, but early and maintained beta-blocker therapy was associated with dose-dependent reduction in disease-related mortality in the multivariate model (p=0.028), and final dose was also associated with reduced heart failure mortality (p=0.008). Kaplan-Meier survival curves analysed in initial dose bands of 0–74, 75–149 and ≥150 mg metoprolol/day showed 10-year freedom from disease-related deaths of 83.1%, 90.7% and 97.0%, respectively (ptrend=0.00008). Even after successful relief of outflow obstruction by intervention, there was survival benefit of metoprolol doses ≥100 mg/day (p=0.01).ConclusionsIn population-based HOCM cohorts heart failure is a dominant cause of death and on multivariate analysis beta-blocker therapy was associated with a dose-dependent cardioprotective effect on total, disease-related as well as heart failure-related mortality.

Abstract Background Current classification systems recommended by major international guidelines are based on a single domain of atrial fibrillation (AF): temporal pattern, symptom severity or underlying comorbidity. Lack of integration between these various elements limits our approach to patients with AF and acts as a barrier against the delivery of better holistic care. The 4S-AF classification scheme was recently introduced as a means for the characterisation of patients with AF. It comprises of 4 domains: stroke risk (St), symptoms (Sy), severity of AF burden (Sb) and substrate (Su). We sought to examine the implementation of the 4S-AF scheme in the EORP-AF General Long-Term Registry and effects of individual domains on outcomes in AF. Methods Patients with AF from 250 centres across 27 participating European countries were included. All patients were over 18 years old and had electrocardiographic confirmation of AF within 12 months prior to enrolment. Data on demographics and comorbidities were collected at baseline. Individual domains of the 4S-AF scheme were assessed using the CHA2DS2-VASc score (St), European Heart Rhythm Association classification (Sy), temporal classification of AF (Sb), and cardiovascular risk factors and the degree of left atrial enlargement (Su). Each of these domains were used during multivariable cox regression analysis. Results A total of 6321 patients were included in the present analysis, corresponding to 57.0% of the original cohort of 11096 patients. The median age of patients was 70 (interquartile range [IQR] 62–77) years with 2615 (41.4%) females. Among these patients, 528 (8.4%) had low stroke risk (St=0), 3002 (47.5%) no or mild symptoms (Sy=0), 2558 (40.5%) newly diagnosed or paroxysmal AF (Sb=0), and 322 (5.1%) no cardiovascular risk factors or left atrial enlargement (Su=0). Median follow-up was 24 months. Using multivariable cox regression analysis, independent predictors of all-cause mortality were (St) (adjusted hazard ratio [aHR] 8.21 [95% CI, 2.60–25.9]), (Sb) (aHR 1.21 [95% CI, 1.08–1.35]) and (Su) (aHR 1.27 [95% CI, 1.14–1.41]). For cardiovascular mortality and any thromboembolic event, only (Su) (aHR 1.73 [95% CI, 1.45–2.06]) and (Sy) (aHR 1.29 [95% CI, 1.00–1.66]) were statistically important, respectively. None of the domains were independently linked to ischaemic stroke or major bleeding. Conclusion Overall, we demonstrated that the 4S-AF scheme may be used to provide clinical characterisation of patients with AF using routinely collected data, and each of the domains within the 4S-AF scheme were independently associated with adverse long-term outcomes of all-cause mortality, cardiovascular mortality and/or any thromboembolic event.

Abstract Background In patients undergoing permanent DDD cardiac pacing, the maintenance of atrial contractility is important to ensure adequate ventricular filling and to guarantee an optimal ventricular ejection capacity. Atrial fibrillation (AF) is a major risk factor for thromboembolic events and is associated with increased cardiovascular and all-cause mortality. Purpose To analyse the risk factors for development of permanent AF in patients with DDD pacemaker and determine its association with all-cause mortality in long-term follow-up. Methods Retrospectively collected records comprised all consecutive patients who underwent primary DDD pacemaker implantation at single-centre between 1984–2014. Patients who were lost to follow-up after hospital discharge were excluded from analysis. Follow-up was completed on 31st August 2016. Definition of permanent AF was the occurence of AF which persisted until the end of follow-up. Data on patients' survival status and deceased patients' dates of death were collected from the national death registration system. Information of death date was available as of 31st August 2016. The endpoint was all-cause mortality. Results We included a total of 3771 patients and 24,432 patient-years of follow-up and exluded 157 (4%) patients who were lost to follow-up after hospital discharge. Mean follow-up was 78±62 months (max. 370 months), 1761 (47%) were female. Paroxysmal AF prior to DDD pacemaker implantation was detected in 1276 patients (34%). During entire follow-up 717 (19%) patients developed permanent AF in a mean period of 55±50 months. Analysis of risk factors for development of permanent AF is presented in Figure. Cox proportional hazards model with time-dependent covariate showed that development of permanent AF significantly increased mortality during follow-up (HR = 1.885, 95% CI, 1.654–2.148, P<0.001; with adjustment for age at implantation and sex: HR = 1.475, 95% CI, 1.294–1.682, P<0.001). Permanent AF risk factors Conclusions Female sex protected against permanent AF development, whereas age at implantation, history of paroxysmal AF and apical position of RV lead increased the risk. Permanent AF was significantly increasing the all-cause mortality, even after adjustment for age at implant and gender. Acknowledgement/Funding None

Background: The relationship between fasting hyperglycemia (FHG) and new-onset atrial fibrillation (AF) in patients with acute myocardial infarction (AMI) is unclear, and whether their co-occurrence is associated with a worse in-hospital and long-term prognosis than FHG or AF alone is unknown.Objective: To explore the correlation between FHG and new-onset AF in patients with AMI, and their impact on in-hospital and long-term all-cause mortality.Methods: We performed a retrospective cohort study comprising 563 AMI patients. The patients were divided into the FHG group and the NFHG group. The incidence of new-onset AF during hospitalization was compared between the two groups and sub-groups under different Killip grades. Logistic regression was used to assess the association between FHG and new-onset AF. In-hospital mortality and long-term all-cause mortality were compared among patients with FHG, AF, and with both FHG and AF according to 10 years of follow-up information.Results: New-onset AF occurred more frequently in the FHG group than in the NFHG group (21.6 vs. 9.2%, p &lt; 0.001). This trend was observed for Killip grade I (16.6 vs. 6.5%, p = 0.002) and Grade II (17.1 vs. 6.9%, p = 0.005), but not for Killip grade III–IV (40 vs. 33.3%, p = 0.761). Logistic regression showed FHG independently correlated with new-onset AF (OR, 2.56; 95% CI, 1.53–4.30; P &lt; 0.001), and 1 mmol/L increased in fasting glucose was associated with a 5% higher rate of new-onset AF, after adjustment for traditional AF risk factors. AMI patients complicated with both fasting hyperglycemia and AF showed the highest in-hospital mortality and long-term all-cause mortality during an average of 11.2 years of follow-up. Multivariate Cox regression showed FHG combined with AF independently correlated with long-term all-cause mortality after adjustment for other traditional risk factors (OR = 3.13, 95% CI 1.64–5.96, p = 0.001), compared with the group with neither FHG nor new-onset AF.Conclusion: FHG was an independent risk factor for new-onset AF in patients with AMI. AMI patients complicated with both FHG and new-onset AF showed worse in-hospital and long-term all-cause mortality than with FHG or AF alone.

Abstract Background Physical activity (PA) may have a beneficial contribution for outcomes in patients with atrial fibrillation (AF). Purpose We aimed to evaluate the impact of self-reported PA in a large contemporary cohort of European AF patients on the risk of all-cause mortality. Methods We analyzed patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Self-reported PA was categorized, on the basis of reported time spent exercising, as follows: i) No PA; ii) Occasional PA; iii) Regular PA; iv) Intense PA. The primary outcome was all-cause death. Results Over 11096, a total of 8699 (78.4%) patients (mean age (SD) 69.1 (11.5); 40.7% female) had available data about PA and follow-up observation and were included in the analysis. Of these, 3703 (42.6%) reported no PA, 2829 (32.5%) occasional PA, 1824 (21.0%) regular PA, with only 343 (3.9%) reporting intense PA. With the 4 increasing PA categories, mean age, proportion of female patients, CHA2DS2-VASc and HAS-BLED scores were progressively lower (all p&lt;0.001). Use of vitamin K antagonist (VKA) declined across the classes of PA (53.1% vs. 52.2% vs. 44.5% vs. 33.9%, p&lt;0.001), while use of non-VKA OACs (NOACs) conversely increased. During a mean (SD) 680.6 (171.5) days of follow-up, there were a total of 848 (9.7%) all-cause death events. Based on Kaplan-Meier analysis, there was a progressively lower cumulative risk for all-cause death according to PA categories [Figure]. A multivariable Cox regression analysis, adjusting for CHA2DS2-VASc score, use of OAC at baseline and type of AF, found a lower risk of all-cause death associated with increasing levels of PA (Hazard ratio [HR]: 0.69, 95% confidence interval [CI]: 0.59–0.81 for occasional PA, HR: 0.45, 95% CI: 0.35–0.58 for regular PA, HR: 0.41, 95% CI: 0.23–0.76 for intense PA, when compared to no PA). In a sensitivity analysis, a regular-intense PA was inversely associated with occurrence of cardiovascular (CV) death, after multivariable adjustments for comorbidities (HR: 0.54, 95% CI: 0.37–0.77). Conclusions In a large contemporary cohort of European AF patients, self-reported PA was found to be inversely associated with all-cause death and CV death.

Background: Previous studies reported that patients with coronary artery disease (CAD) and well-controlled baseline LDL-C (&lt;1.8 mmol/L) still had higher long-term all-cause mortality. However, no study has been conducted to explore the independent risk factors for long-term mortality. In addition, there also was no study evaluating the population attributable risk (PAR) of independent risk factors in combination with their prevalence and relative risk. Therefore, we aimed to identify the independent risk factors and estimate their PAR in patients with CAD and well-controlled baseline LDL-C (&lt;1.8 mmol/L).Methods: We analyzed 4,863 consecutive CAD patients with well-controlled baseline LDL-C admitted to Guangdong Provincial People's Hospital in China from January 2007 to December 2018. Independent risk factors for long-term all-cause death were evaluated through stepwise approach and multivariable Cox regression analysis. PAR of independent risk factors was calculated with their hazard ratio and prevalence among our cohort.Results: The overall mortality was 16.00% (n = 778) over a median follow-up period of 5.93 years. Independent risk factors for all-cause death included malnutrition, age ≥75 years, congestive heart failure (CHF), chronic kidney disease (CKD) and atrial fibrillation. Among these risk factors of interest, the hazard ratio (HR) of severe malnutrition was the highest (HR 2.82, 95% CI: 1.86–4.26), and the PAR of mild malnutrition was the highest (19.49%, 95% CI: 0.65–36.01%).Conclusion: Malnutrition, age ≥75 years, CHF, CKD and atrial fibrillation were independent predictors for long-term all-cause mortality in CAD patients with well-controlled LDL-C levels. Considering prevalence of these risk factors, more attention should be paid to the occurrence of mild malnutrition for these patients.Clinical Trial Registration:ClinicalTrials.gov, identifier: NCT04407936.

Abstract Purpose Despite advances in the care of hip fractures, this area of surgery is associated with high postoperative mortality. Downregulating circulating catecholamines, released as a response to traumatic injury and surgical trauma, is believed to reduce the risk of death in noncardiac surgical patients. This effect has not been studied in hip fractures. This study aims to assess whether survival benefits are gained by reducing the effects of the hyper-adrenergic state with beta-blocker therapy in patients undergoing emergency hip fracture surgery. Methods This is a retrospective nationwide observational cohort study. All adults $$\ge$$ ≥ 18 years were identified from the prospectively collected national quality register for hip fractures in Sweden during a 10-year period. Pathological fractures were excluded. The cohort was subdivided into beta-blocker users and non-users. Poisson regression with robust standard errors and adjustments for confounders was used to evaluate 30-day mortality. Results 134,915 patients were included of whom 38.9% had ongoing beta-blocker therapy at the time of surgery. Beta-blocker users were significantly older and less fit for surgery. Crude 30-day all-cause mortality was significantly increased in non-users (10.0% versus 3.7%, p < 0.001). Beta-blocker therapy resulted in a 72% relative risk reduction in 30-day all-cause mortality (incidence rate ratio 0.28, 95% CI 0.26–0.29, p < 0.001) and was independently associated with a reduction in deaths of cardiovascular, respiratory, and cerebrovascular origin and deaths due to sepsis or multiorgan failure. Conclusions Beta-blockers are associated with significant survival benefits when undergoing emergency hip fracture surgery. Outlined results strongly encourage an interventional design to validate the observed relationship.
