RESUMEN
BACKGROUND: Adults with congenital heart disease (ACHD) and atrial arrhythmias (AA) face an increased risk of thromboembolic events. Limited data exist on the use of non-vitamin K oral anticoagulants for thromboprophylaxis in ACHD. We aimed to assess the effectiveness and safety of apixaban in ACHD patients with AA. METHODS: PROTECT-AR (NCT03854149) was a prospective, multicenter, observational study conducted from 2019 to 2023. ACHD patients with atrial fibrillation, atrial flutter, or intra-atrial re-entrant tachycardia on routine apixaban treatment were included. The historical control group consisted of patients previously on vitamin K antagonist (VKA), who were analyzed prior to their transition to apixaban. The primary effectiveness endpoint was the composite of stroke or thromboembolism. The primary safety endpoint was major bleeding. RESULTS: The study enrolled 218 ACHD patients with AA on apixaban, of which 73 were previous VKA users. The analysis covered 527 patient-years of prospective exposure to apixaban and 169 patient-years of retrospective exposure to VKA. The annualized rate of stroke or thromboembolism was 0.6% in the apixaban group and 1.8% in the VKA group (absolute difference - 1.2%; upper limit of one-sided 95% confidence interval [CI] 0.9%, lower than the predefined non-inferiority margin of +1.8%, Pnon-inferiority < 0.001). The annualized rate of major bleeding was 1.5% in the apixaban group and 2.4% in the VKA group (hazard ratio 0.64; 95% CI 0.19-2.10, P = 0.48). CONCLUSION: In ACHD patients with AA, routine apixaban use exhibited a non-inferior rate of stroke or thromboembolism compared to historical VKA use, alongside a similar rate of major bleeding.

Background Although previous studies showed that atrial high-rate episodes (AHREs) are associated with a higher risk of developing incident atrial fibrillation (AF) and thromboembolic events, their clinical significance is still unclear. The purpose of this study was to define whether there is any clinical impact on the occurrence of ischemic and hemorrhagic events in patients with AHREs and initiation of oral anticoagulation (OAC). Methodology Patients with AHREs who had received cardiac implantable electronic devices (CIEDs, i.e., dual-chamber pacemaker [PM] or implantable cardioverter defibrillator [ICD]) were included in the study. OAC initiation was decided by the assistant doctor. Patients who received OACs comprised the OAC group, while patients who were not referred for OAC initiation were included in the control group. The primary endpoint was the time to the event of the occurrence of thromboembolic events (thromboembolic event-free survival). Results A total of 154 individuals (77 in each group) were enrolled in the study, with a mean age of 72.5 years. The mean follow-up period for the OAC group was 19.1 months and for the control group, 18.9 months (P = 0.9). Thromboembolic events were noticed only in seven patients. Six of them were in the control group, and only one in the OAC group (P = 0.05). Major bleeding events were noticed in five patients, one of whom was in the control group and the rest in the OAC group (P = 0.17). Conclusions OAC therapy in patients with AHREs was not associated with a significant difference in the risk of thromboembolic and bleeding events. Baseline patient characteristics and AHRE duration may be useful to intensify the monitoring and management of patients with AHREs. Bleeding events may be indicators of cancer in patients with AHREs receiving OACs.
RESUMEN
(1) Background: Patients with diabetes mellitus (DM) are at increased risk for heart failure (HF). Accurate data regarding the prevalence of HF stages among diabetics in Greece are scarce. (2) Aim: The present study will examine the prevalence and evolution of HF stages among patients with type II DM (T2DM) diagnosed in the past 10 years, with no previous history of HF and at high CV risk, in Greece, as well as will explore the potential determinants of the development of symptomatic HF in these patients. (3) Methods: Through a non-interventional, epidemiological, single-country, multi-center, prospective cohort study design, a sample of 300 consecutive patients will be enrolled in 11 cardiology departments that are HF centers of excellence. Patients will be either self-referred or referred by primary or secondary care physicians and will be followed for up to 24 months. Demographic, clinical, echocardiography, electrocardiography, cardiac biomarkers (troponin, NT-proBNP) and health-related quality of life questionnaire data will be recorded as well as clinical events, including mortality, HF hospitalizations and HF-related healthcare resource utilization. The primary outcomes are the proportion of patients diagnosed with symptomatic HF (ACC/AHA Stage C) at enrolment in the overall study population and the proportions of patients with HF stages A, B and C, as well as by NYHA functional classification in the overall study population. (4) Conclusions: The HF-LanDMark study is the first epidemiological study that will assess the prevalence of HF among T2DM patients in Greece that could potentially enhance prompt therapeutic interventions shown to delay the development of HF in the T2DM patient population (HF-LanDMark, Clinical Trials.gov number, NCT04482283).
RESUMEN
Aim: This research aims to develop a consistent computational model of a normal mitral valve (MV) and describe mitral regurgitation (MR) geometry based on Carpentier's classification. Materials & methods: MV geometry was assessed by 2D transthoracic echocardiogram in 100 individuals. A 3D parametric geometric model of the MV was developed. A computational model of a normal MV was performed. Results: The simulation of the valve function was successfully accomplished and its kinematics was analyzed. Differences in geometry were revealed between normal and type III MR. Conclusion: 3D computational models of the normal MV can be constructed relying on standard measurements performed by 2D echocardiography. Certain geometrical differences exist among the normal and the most severe type of MR.

Heart failure (HF) is among the leading causes of unplanned hospital admissions worldwide. Patients with HF carry a high burden of comorbidities; hence, they are frequently admitted for non-cardiac conditions and managed in Internal Medicine Departments (IMD). The aim of our study was to investigate differences in demographics, in-hospital management, and short-term outcomes of HF patients admitted to IMD vs. cardiology departments (CD). A prospective cohort study enrolling consecutive patients with acutely decompensated HF either as primary or as secondary diagnosis during the index hospitalization was conducted. Our primary endpoint was a combined endpoint of in-hospital mortality and 30-day rehospitalization for HF. A total of 302 patients participated in the study, with 45% of them admitted to IMD. Patients managed by internists were older with less pronounced HF symptoms on admission. In-hospital mortality was higher for patients admitted to IMD vs. CD (21% vs. 6%, p < 0.001). The composite endpoint of in-hospital death and heart failure hospitalizations at 30 days post-discharge was higher for patients admitted to IMD both in univariate [OR: 3.2, 95% CI (1.8-5.7); p < 0.001] and in multivariate analysis [OR 3.74, 95% CI (1.72-8.12); p = 0.001]. In addition, the HF rehospitalization rate at 6 months after discharge was higher in IMD patients [HR 1.65, 95% CI (1.1, 2.4), p = 0.01]. Overall, HF patients admitted to IMD have worse short-term outcomes compared to patients admitted to CD.
RESUMEN
Thromboembolism is a significant complication after the Fontan procedure because of endothelial dysfunction, abnormal blood flow, and hypercoagulability. This is the reason why it is recommended for these patients to receive thromboprophylaxis. The aim of our study was to compare the efficacy and safety of antiplatelets versus anticoagulants in patients with a history of a Fontan procedure. A systematic literature review was performed on the electronic databases PubMed, Cochrane, and Scopus, and the grey literature for retrieving studies comparing antiplatelets with anticoagulants and/or no medication on patients with Fontan circulation. We used the random effect model for synthesizing the data. A total of 26 and 20 studies were included in the qualitative and quantitative analysis, respectively. No difference was observed between antiplatelets and anticoagulants in the rate of thromboembolic events [odds ratio (OR), 1.47; 95% confidence interval (CI), 0.66-3.26]. Anticoagulants were more effective than no medication for thromboprophylaxis (OR, 0.17; 95% CI, 0.05-0.61), while comparison between antiplatelets and no medication showed no difference in thromboembolic episodes (OR, 0.25; 95% CI, 0.06-1.09). Antiplatelets were safer than anticoagulants with regards to any bleeding episodes (OR, 0.57; 95% CI, 0.34-0.95). In conclusion, no difference could be found between antiplatelets and anticoagulants in terms of efficacy. However, antiplatelets seem to be safer, as they are responsible for fewer bleeding events. Additional randomized controlled trials are needed to produce robust results.
RESUMEN
PURPOSE OF REVIEW: Acute heart failure (AHF) is among the leading causes for unplanned hospital admission. Despite advancements in the management of chronic heart failure, the prognosis of AHF remains poor with high in-hospital mortality and increased rates of unfavorable post-discharge outcomes. With this review, we aim to summarize current data on AHF epidemiology, focus on the different patient profiles and classifications, and discuss management, including novel therapeutic options in this area. RECENT FINDINGS: There is significant heterogeneity among patients admitted for AHF in their baseline characteristics, heart failure (HF) aetiology and precipitating factors leading to decompensation. A novel classification scheme based on four distinct clinical scenarios has been included in the most recent ESC guidelines, in an effort to better risk stratify patients and guide treatment. Intravenous diuretics, vasodilators, and inotropes remain the cornerstone of management in the acute phase, and expansion of use of mechanical circulatory support has been noted in recent years. Meanwhile, many treatments that have proved their value in chronic heart failure demonstrate promising results in the setting of AHF and research in this field is currently ongoing. Acute heart failure remains a major health challenge with high in-hospital mortality and unfavorable post-discharge outcomes. Admission for acute HF represents a window of opportunity for patients to initiate appropriate treatment as soon as possible after stabilization. Future studies are needed to elucidate which patients will benefit the most by available therapies and define the optimal timing for treatment implementation.

The prognostic value of health status metrics in patients with adult congenital heart disease (ACHD) and atrial arrhythmias is unclear. In this retrospective cohort study of an ongoing national, multicenter registry (PROTECT-AR, NCT03854149), ACHD patients with atrial arrhythmias on apixaban are included. At baseline, health metrics were assessed using the physical component summary (PCS), the mental component summary (MCS) of the Short-Form-36 (SF-36) Health Survey, and the modified European Heart Rhythm Association (mEHRA) score. Patients were divided into groups according to their SF-36 PCS and MCS scores, using the normalized population mean of 50 on the PCS and MCS as a threshold. The primary outcome was the composite of mortality from any cause, major thromboembolic events, major/clinically relevant non-major bleedings, or hospitalizations. Multivariable Cox-regression analyses using clinically relevant parameters (age greater than 60 years, anatomic complexity, ejection fraction of the systemic ventricle, and CHA2DS2-VASc and HAS-BLED scores) were performed to examine the association of health metrics with the composite outcome. Over a median follow-up period of 20 months, the composite outcome occurred in 50 of 158 (32%) patients. The risk of the outcome was significantly higher in patients with SF-36 PCS ≤ 50 compared with those with PCS > 50 (adjusted hazard ratio (aHR), 1.98; 95% confidence interval [CI], 1.02−3.84; p = 0.04) after adjusting for possible confounders. The SF-36 MCS ≤ 50 was not associated with the outcome. The mEHRA score was incrementally associated with a higher risk of the composite outcome (aHR = 1.44 per 1 unit increase in score; 95% CI, 1.03−2.00; p = 0.03) in multivariable analysis. In ACHD patients with atrial arrhythmias, the SF-36 PCS ≤ 50 and mEHRA scores predicted an increased risk of adverse events.
RESUMEN
Coronary artery disease (CAD) represents a modern pandemic associated with significant morbidity and mortality. The multi-faceted pathogenesis of this entity has long been investigated, highlighting the contribution of systemic factors such as hyperlipidemia and hypertension. Nevertheless, recent research has drawn attention to the importance of geometrical features of coronary vasculature on the complexity and vulnerability of coronary atherosclerosis. Various parameters have been investigated so far, including vessel-length, coronary artery volume index, cross-sectional area, curvature, and tortuosity, using primarily invasive coronary angiography (ICA) and recently non-invasive cardiac computed tomography angiography (CCTA). It is clear that there is correlation between geometrical parameters and both the haemodynamic alterations augmenting the atherosclerosis-prone environment and the extent of plaque burden. The purpose of this review is to discuss the currently available literature regarding this issue and propose a potential non-invasive imaging biomarker, the geometric risk score, which could be of importance to allow the early detection of individuals at increased risk of developing CAD.
RESUMEN
BACKGROUND: Cardiac magnetic resonance (CMR) is considered the gold standard for the assessment of right ventricular ejection fraction (RVEF). Previous studies have suggested that RVEF may be a predictor of adverse outcomes in heart failure (HF). In this study, we aimed to systematically review the prognostic value of RVEF, evaluated by CMR, across the spectrum of left ventricular systolic function in patients with HF. METHODS: Electronic databases were searched for studies investigating the prognostic value of RVEF in HF, irrespective of left ventricular ejection fraction (LVEF). A random-effects meta-analysis was conducted for mortality and HF hospitalization. Subgroup analyses were also performed based on the presence of reduced (<50%) or preserved LVEF (≥50%). RESULTS: In total, 46 studies enrolling 14,344 patients were included. In the pooled analyses, impaired RVEF was a powerful predictor of mortality (HR: 1.26, 95% CI: 1.18-1.33, I2: 13%, per 10% decrease in RVEF) and death or HF hospitalization (HR: 1.31, 95% Cl: 1.2-1.42, I2: 27%, per 10% decrease in RVEF). A decrease in RVEF was strongly associated with increased risk of mortality or hospitalization both in HF with reduced EF (HR: 1.24, 95% CI: 1.13-1.36, I2: 2%, per 10% decrease in RVEF) and in HF with preserved EF (HR: 1.24, 95% CI: 1.09-1.40, I2: 0%, per 10% decrease in RVEF). CONCLUSION: Impaired RVEF on CMR strongly predicts adverse outcomes in patients with HF regardless of LVEF. RV systolic function should be carefully evaluated in these patients.

BACKGROUND: Digoxin is widely used in atrial fibrillation (AF) and heart failure (HF). However, current evidence regarding its association with clinical outcomes is conflicting. AIM: To investigate the relationship between digoxin therapy and adverse outcomes in patients with AF, with or without HF, in a contemporary AF cohort. METHODS: We performed a retrospective analysis of data from 698 patients, who were followed over a median of 2.5 years. The primary outcome was all-cause mortality and the secondary outcome was all-cause hospitalization, in a time-to-event analysis. Propensity scores were used to derive matched populations, balanced on key baseline covariates. To limit potential confounding, inverse probability of treatment weighting (IPTW) analysis was performed. RESULTS: Among patients with HF, 39 (10.5%) were administered digoxin at baseline, whereas 331 (89.5%) were not. Digoxin administration was not associated with an increased risk of death (hazard ratio (HR) in the digoxin group, 1.21; 95% Confidence Interval (CI), 0.69 to 2.13, p = 0.50) or hospitalization of any cause (HR 1.15; 95% CI, 0.67 to 1.96; p = 0.60). Among patients without HF, 11 (3.5%) were administered digoxin, with neutral effects on all-cause mortality (HR: 3.25; 95% CI, 0.98 to 10.70), p = 0.06) and all-cause hospitalization (HR, 1.15; 95% CI, 0.67 to 1.96, p = 0.60). Qualitatively, consistent results were observed using IPTW. CONCLUSIONS: Among patients with AF, digoxin administration was not associated with an increased risk of death and hospitalization for any cause, irrespective of HF status.

ABSTRACT: Patients with atrial fibrillation (AF) often receive multiple medications daily. The purpose of this study was to examine the prognostic implications of polypharmacy in patients with AF. This is a retrospective post hoc analysis of 1113 AF patients, enrolled in a randomized trial during an acute hospitalization (MISOAC-AF, NCT02941978). The presence of polypharmacy (use of >4 drugs daily) was assessed at hospital discharge. Regression analyses were performed to identify clinical predictors of polypharmacy and compare the outcomes of patients with or without confirmed polypharmacy. The coprimary outcomes were all-cause and cardiovascular (CV) mortality. Among patients with polypharmacy, the difference in the risk of mortality was also assessed per each added drug as a numeric variable. Polypharmacy was found in 36.9% of participants. Dyslipidemia, coronary artery disease, lower left ventricular ejection fraction, and higher glomerular filtration rates were independent predictors of polypharmacy. Polypharmacy was an independent predictor for all-cause death (adjusted hazard ratio [aHR]: 1.29, 95% confidence interval [CI]: 1.01-1.64) and CV death (aHR: 1.39, 95% CI: 1.05-1.84). Among patients with polypharmacy, each additional concomitant medication was independently associated with a 4% increased risk of all-cause mortality (aHR = 1.04, 95% CI: 1.00-1.08) and a 5% increased risk of CV mortality (aHR = 1.05, 95% CI: 1.00-1.10). Polypharmacy was common among patients with AF hospitalized in a tertiary hospital and was incrementally associated with higher rates of mortality.

BACKGROUND: Recent studies have shown that mitral regurgitation (MR) represents a major determinant of left atrial (LA) function in patients with heart failure with preserved ejection fraction. The role of MR in determining LA myopathy in hypertrophic cardiomyopathy (HCM) is unknown. The aim of this study was to examine the association of MR with LA myopathy, assessed by LA strain values in HCM patients. METHODS: In total 250 consecutive patients (mean age 51 ± 16 years, 67.2% male) with an established diagnosis of HCM and with sinus rhythm at index echocardiography evaluation were included. LA reservoir, conduit and booster strain were analyzed, besides LA size, left ventricular (LV) systolic and diastolic function. The predictors of LA strain values were identified with linear regression analysis. RESULTS: Significant (more than mild) MR was a significant univariate predictor of all the three LA strain values. In multivariate linear regression analysis, independent predictors of LA reservoir strain were more than mild MR (r = -.23), LV global longitudinal strain (r = -.49), LA volume index (r = -.27) and patient age (r = -.23). Significant MR was also an independent determinant of LA conduit (r = -.17) and booster strain (r = -.12). In patients with LA volume index < 34 ml/m2 more than mild MR was an independent predictor of LA reservoir (r = -.32) and conduit strain (r = -.27), but not LA booster strain. CONCLUSION: Significant MR is associated with LA myopathy independently of the LV diastolic and systolic function and LA size.

AIM: The aim of this study is to examine the association of the presence of chronic kidney disease (CKD) and estimated glomerular filtration rate (eGFR) values with mortality in patients with atrial fibrillation. METHODS: This posthoc analysis of a randomized controlled trial consisted of hospitalized patients with atrial fibrillation who were followed up for a median of 2.7âyears after discharge. Kaplan-Meier curves, multivariate Cox-regression and spline curves were utilized to assess the association of CKD, CKD stages 2-5 according to the KDOQI guidelines, and the continuum of eGFR values with the primary outcome of all-cause death, and the secondary outcome of cardiovascular mortality. RESULTS: Out of 1064 hospitalized patients with atrial fibrillation, 465 (43.7%) had comorbid CKD. The presence of CKD was associated with an increased risk for both all-cause and cardiovascular mortality following hospitalization [adjusted hazard ratio (aHR): 1.60; 95% confidence intervals (95% CIs): 1.25-2.05 and aHR: 1.74; 95% CI: 1.30-2.33, respectively]. The aHRs for all-cause mortality in CKD stages 2-5, as compared with CKD stage 1 were 2.18, 2.62, 4.20 and 3.38, respectively (all Pâ<â0.05). In spline curve analyses, eGFR values lower than 50âml/min/1.73âm2 were independent predictors of higher all-cause and cardiovascular mortality. CONCLUSION: In recently hospitalized patients with atrial fibrillation, the presence of CKD was independently associated with decreased survival, which was significant across CKD stages 2-5, as compared with CKD stage 1. Values of eGFR lower than 50âml/min/1.73âm2 were incrementally associated with worse prognosis.

AIM: Education level has been long considered a life-quality modifier, but little is known about its relation to life expectancy in patients with cardiovascular disease. This study aims to assess possible correlations between education level and survival in patients with atrial fibrillation (AF). METHODS: This retrospective cohort study used data from a randomised trial of 1082 hospitalised patients with AF (mean age of 75 ± 11 years) who were followed up after discharge. Patients were divided into three groups based on their education level: i) none or primary (NPEL), ii) secondary (SEL), and iii) tertiary education level (TEL). Kaplan-Meier curves and multivariable-adjusted hazard ratios (aHRs) were used to compare survival rates between groups. The primary outcome was all-cause mortality. The composite secondary outcome was cardiovascular mortality or any hospitalisation. RESULTS: After a median 31-month follow-up period, 289 (41.9%) patients died in the NPEL group, 75 (31.1%) in the SEL group, and 29 (19.1%) in the TEL group. The aHRs for all-cause mortality were 0.42 (95% CI, 0.27 to 0.66; p < 0.001) for the TEL group compared with the NPEL group, 0.55 (95% CI, 0.33 to 0.93; p = 0.02) for the TEL group compared with the SEL group, and 0.68 (95% CI, 0.50 to 0.93; p = 0.01) for the SEL group compared with the NPEL group. The corresponding aHRs for the composite secondary outcome were 0.36 (95% CI, 0.23 to 0.52; p < 0.001), 0.49 (95% CI, 0.29 to 0.80; p < 0.001), and 0.67 (95% CI, 0.50 to 9.91; p = 0.01). CONCLUSION: Higher education levels were independently associated with fewer fatal and non-fatal outcomes in recently hospitalised patients with AF.

BACKGROUND: Currently, potent P2Y12 inhibition with the use of prasugrel or ticagrelor is the mainstay of treatment after an acute coronary syndrome (ACS). The 2020 European Society of Cardiology (ESC) Guidelines recommend the use of prasugrel over ticagrelor in patients with non-ST-elevation ACS (NSTE-ACS) intended to receive invasive management (class IIa recommendation), however there are contradictory views regarding this recommendation. AIM: To compare oral P2Y12 inhibitors in NSTE-ACS in terms of efficacy and safety with a focus on patients intended to proceed to invasive management. METHODS: We systematically searched PubMed, Cochrane Central Register of Controlled Trials and Web of Science to identify studies that compared different oral P2Y12 inhibitors (clopidogrel, prasugrel and ticagrelor) in patients with NSTE-ACS. Efficacy outcomes included the major adverse cardiovascular events outcome and safety outcomes included minor and major bleedings. We performed a frequentist network meta-analysis. RESULTS: Nine studies (n=35 441 patients) were included in the systematic review. There was no difference between prasugrel and ticagrelor in the composite cardiovascular end point (prasugrel vs ticagrelor HR=0.80, 95% CI=0.61 to 1.06) in all patients with NSTE-ACS. In patients intended to receive invasive management, prasugrel resulted in a reduction of the composite cardiovascular end point both versus clopidogrel (HR=0.76, 95% CI=0.61 to 0.95) and ticagrelor (HR=0.74, 95% CI=0.56 to 0.98). Inconsistency was moderate and non-significant (I2=27%, total Q p=0.2). Prasugrel ranked as the most efficient treatment in the composite cardiovascular efficacy outcome, all-cause death, myocardial infarction and definite stent thrombosis, while clopidogrel ranked as safest in the bleeding outcomes. CONCLUSION: In patients with NSTE-ACS intended to receive invasive management, an antiplatelet strategy based on prasugrel is more efficient than a similar strategy based on ticagrelor on a moderate level of evidence. This analysis supports the current recommendations by the ESC guidelines.

BACKGROUND: Superiority of potent P2Y12 inhibitors over clopidogrel after an acute coronary syndrome (ACS) has been well established, however potent P2Y12 inhibition is responsible for more adverse events, which may influence patient adherence to treatment. Aim of the present study is to investigate the adherence to the prescribed P2Y12 inhibitor (P2Y12i) in patients on dual antiplatelet therapy (DAPT) after an ACS. METHODS: In an IDEAL-LDL trial substudy, we included 344 patients after ACS discharged on DAPT. The primary outcome was the difference between potent P2Y12i and clopidogrel in terms of adherence, as well as other predictors of adherence to the antiplatelet regimen. Secondary outcomes included the prevalence of DAPT continuation and its predictors and the antiplatelet regimen selection after DAPT. RESULTS: Adherence to the potent P2Y12i and to clopidogrel was observed in 140/178 (78.7%) and 111/166 (66.9%) patients (p = 0.016), respectively. In the multivariate model, after adjustment for P2Y12i switching during the first year of therapy, there was no difference observed in adherence between potent P2Y12i and clopidogrel (odds ratio [OR] = 0.98, 95% confidence interval [CI] = 0.55-1.74). Significant predictors included history of cardiovascular disease (CVD) (OR = 0.51, 95% CI = 0.31-0.86) and percutaneous coronary intervention (PCI) index event treatment (OR = 2.58, 95% CI = 1.38-4.82). Of patients, 72% continued DAPT >12 months and female gender was a negative predictor of DAPT prolongation (adjusted OR = 0.43, 95% CI = 0.21-0.90). DAPT was continued until the end of follow-up in 42.7%, while 54.6% resumed with single antiplatelet regimen. CONCLUSIONS: Adherence to DAPT was not affected by the P2Y12i potency, whereas history of CVD and PCI treatment were associated with reduced and increased adherence, respectively.

BACKGROUND: Rhythm control and rate control are both employed commonly in patients with atrial fibrillation (AF) and heart failure (HF), but limited real-world data exist on them. We aimed to compare outcomes between these two strategies across the left ventricular ejection fraction (LVEF) spectrum. MATERIALS AND METHODS: This retrospective cohort study used data from the randomized MISOAC-AF trial, including from patients with AF and coexistent HF who were hospitalized and followed up after discharge. At baseline, the patients were classified into pharmaceutical (or electrical cardioversion) rhythm control strategy or rate control treatment (b-blocker, digoxin, calcium channel blockers) groups. The primary outcome was all-cause mortality. Kaplan-Meier curves and multivariable-adjusted Cox regression were utilized to compare the two strategies. Spline curve models were used to demonstrate the results across the LVEF stratified spectrum. RESULTS: In total, 199 AF patients with HF were studied (mean age, 77 years). At discharge, 73 (36.7%) patients received rhythm control and 126 (63.3%) rate control treatment. After a median follow-up period of 31 months, 26 (35.6%) patients in the rhythm-control group died, as compared to 43 (33.3%) in the rate-control group (aHR: 1.29; 95% CI: 0.78-2.14; p = 0.31). The spline curves also revealed no difference in all-cause mortality favoring either strategy in any HF subtype across the nominally classified LVEF. CONCLUSION: The use of a pharmacological rhythm-control strategy was not associated with a survival advantage compared to the rate control strategy in recently hospitalized patients with AF and comorbid HF. More randomized trials and large studies are needed in the future to explore these results in each subgroup of HF patients.

The implications of the adult congenital heart disease anatomic and physiological classification (AP-ACHD) for risk assessment have not been adequately studied. A retrospective cohort study was conducted using data from an ongoing national, multicentre registry of patients with ACHD and atrial arrhythmias (AA) receiving apixaban (PROTECT-AR study, NCT03854149). At enrollment, patients were stratified according to Anatomic class (AnatC, range I to III) and physiological stage (PhyS, range B to D). A follow-up was conducted between May 2019 and September 2021. The primary outcome was a composite of death from any cause, any major thromboembolic event, major or clinically relevant non-major bleeding, or hospitalization. Cox proportional-hazards regression modeling was used to evaluate the risks for the outcome among AP-ACHD classes. Over a median 20-month follow-up period, 47 of 157 (29.9%) ACHD patients with AA experienced the composite outcome. Adjusted hazard ratios (aHR) with 95% confidence intervals (CI) for the outcome in PhyS C and PhyS D were 1.79 (95% CI 0.69 to 4.67) and 8.15 (95% CI 1.52 to 43.59), respectively, as compared with PhyS B. The corresponding aHRs in AnatC II and AnatC III were 1.12 (95% CI 0.37 to 3.41) and 1.06 (95% CI 0.24 to 4.63), respectively, as compared with AnatC I. In conclusion, the PhyS component of the AP-ACHD classification was an independent predictor of net adverse clinical events among ACHD patients with AA.
