Background: The DOAC score has been recently proposed for bleeding risk stratification of patients with atrial fibrillation treated with direct oral anticoagulants (DOAC)., Objective: To compare the performance of HAS-BLED and DOAC score in predicting major bleeding events in a contemporary cohort of European AF patients treated with DOAC., Methods: We included patients derived from a prospective observational registry of European AF patients. HAS-BLED and DOAC scores were calculated as per the original schemes. Our primary endpoint was major bleeding events. Receiver operating characteristic (ROC) curves were used to compare the predictive ability of the scores., Results: A total of 2834 AF patients (median age [IQR] 69 [62-77] years; 39.6 % female) treated with DOAC were included in the analysis. According to the HAS-BLED score, 577 patients (20.4 %) were categorized as very low risk of bleeding, as compared to 1276 (45.0 %) according to DOAC score. A total of 55 major bleeding events occurred with an overall incidence of 1.04 per 100 patient-years. Both scores showed only a modest ability for the prediction of bleeding events (HAS-BLED area under the curve [AUC], 0.65, 95 % confidence interval [CI] 0.55-0.70; DOAC score AUC 0.62, 95 % CI 0.59-0.71, p for difference = 0.332]. At calibration analysis, the DOAC score showed modest calibration, especially for patients at high risk, when compared to HAS-BLED., Conclusion: In a contemporary cohort of DOAC-treated AF patients, both HAS-BLED and DOAC scores only modestly predicted the occurrence of major bleeding events. Our results do not support the preferential use of DOAC score over HAS-BLED., Competing Interests: Declaration of competing interest GB: reports small speaker fees from Bayer, Boehringer Ingelheim, Boston, BMS, Daiichi, Sanofi and Janssen outside the submitted work.

The management of patients with atrial fibrillation (AF) requires intricate clinical decision-making to optimize outcomes. In everyday clinical practice, physicians undergo difficult choices to better manage patients with AF. They need to balance thromboembolic and bleeding risk to focus on patients' symptoms and to manage a variety of multiple comorbidities. In this review, we aimed to explore the multifaceted dimensions of clinical decision-making in AF patients, encompassing the definition and diagnosis of clinical AF, stroke risk stratification, oral anticoagulant therapy selection, consideration of bleeding risk, and the ongoing debate between rhythm and rate control strategies. We will also focus on possible grey zones for the management of AF patients. In navigating this intricate landscape, clinicians must reconcile the dynamic interplay of patient-specific factors, evolving guidelines, and emerging therapies. The review underscores the need for personalized, evidence-based clinical decision-making to tailor interventions for optimal outcomes according to specific AF patient profiles.

Traditional classifications categorize atrial fibrillation (AF) into paroxysmal, persistent, or permanent, but recent advancements in monitoring have revealed AF as a continuous variable, challenging existing paradigms. AF burden, defined basically as the amount of time spent in AF during a monitored period, has emerged as a crucial metric. This review assesses the evolving landscape of AF burden and its measurement methods, diagnostic modalities, and impact on outcomes. Guidelines suggest individualized approaches, combining AF burden with clinical scores (CHA 2 DS 2 -VASc), but studies have challenged this. Addressing the impact of AF burden on patients' quality of life before or after ablation is also crucial. Although continuous monitoring technologies offer promising avenues, the field faces challenges, such as defining clinically relevant thresholds. Future research should focus on refining these, designing trials centered around AF burden, and evaluating the efficacy of interventions in reducing AF burden, ultimately paving the way for personalized management strategies., Competing Interests: Disclosures Dr Sorgente is a consultant for Biosense Webster, Medtronic, Biotronik, and MicroPort.

Aims: Same-day discharge (SDD) after catheter ablation of atrial fibrillation (AF) may address the growing socio-economic health burden of the increasing demand for interventional AF therapies. This systematic review and meta-analysis analyses the current evidence on clinical outcomes in SDD after AF ablation compared with overnight stay (ONS)., Methods and Results: A systematic search of the PubMed database was performed. Pre-defined endpoints were complications at short-term (24-96 h) and 30-day post-discharge, re-hospitalization, and/or emergency room (ER) visits at 30-day post-discharge, and 30-day mortality. Twenty-four studies (154 716 patients) were included. Random-effects models were applied for meta-analyses of pooled endpoint prevalence in the SDD cohort and for comparison between SDD and ONS cohorts. Pooled estimates for complications after SDD were low both for short-term [2%; 95% confidence interval (CI): 1-5%; I2: 89%) and 30-day follow-up (2%; 95% CI: 1-4%; I2: 91%). There was no significant difference in complications rates between SDD and ONS [short-term: risk ratio (RR): 1.62; 95% CI: 0.52-5.01; I2: 37%; 30 days: RR: 0.65; 95% CI: 0.42-1.00; I2: 95%). Pooled rates of re-hospitalization/ER visits after SDD were 4% (95% CI: 1-10%; I2: 96%) with no statistically significant difference between SDD and ONS (RR: 0.86; 95% CI: 0.58-1.27; I2: 61%). Pooled 30-day mortality was low after SDD (0%; 95% CI: 0-1%; I2: 33%). All studies were subject to a relevant risk of bias, mainly due to study design., Conclusion: In this meta-analysis including a large contemporary cohort, SDD after AF ablation was associated with low prevalence of post-discharge complications, re-hospitalizations/ER visits and mortality, and a similar risk compared with ONS. Due to limited quality of current evidence, further prospective, randomized trials are needed to confirm safety of SDD and define patient- and procedure-related prerequisites for successful and safe SDD strategies., Competing Interests: Conflict of interest: M.M.Z. reports lecture fees/honoraria and travel support by Medtronic, Boston Scientific, Bayer Vital, Pfizer, Abbott, and ZOLL CMS.

Aims: Physiological activation of the heart using algorithms to minimize right ventricular pacing (RVPm) may be an effective strategy to reduce adverse events in patients requiring anti-bradycardia therapies. This systematic review and meta-analysis aimed to evaluate current evidence on clinical outcomes for patients treated with RVPm algorithms compared to dual-chamber pacing (DDD)., Methods and Results: We conducted a systematic search of the PubMed database. The predefined endpoints were the occurrence of persistent/permanent atrial fibrillation (PerAF), cardiovascular (CV) hospitalization, all-cause death, and adverse symptoms. We also aimed to explore the differential effects of algorithms in studies enrolling a high percentage of atrioventricular block (AVB) patients. Eight studies (7229 patients) were included in the analysis. Compared to DDD pacing, patients using RVPm algorithms showed a lower risk of PerAF [odds ratio (OR) 0.74, 95% confidence interval (CI) 0.57-0.97] and CV hospitalization (OR 0.77, 95% CI 0.61-0.97). No significant difference was found for all-cause death (OR 1.01, 95% CI 0.78-1.30) or adverse symptoms (OR 1.03, 95% CI 0.81-1.29). No significant interaction was found between the use of the RVPm strategy and studies enrolling a high percentage of AVB patients. The pooled mean RVP percentage for RVPm algorithms was 7.96% (95% CI 3.13-20.25), as compared with 45.11% (95% CI 26.64-76.38) of DDD pacing., Conclusion: Algorithms for RVPm may be effective in reducing the risk of PerAF and CV hospitalization in patients requiring anti-bradycardia therapies, without an increased risk of adverse symptoms. These results are also consistent for studies enrolling a high percentage of AVB patients., Competing Interests: Conflict of interest: G.B. reports small speaker fees from Bayer, Boehringer Ingelheim, Boston, BMS, Daiichi, Sanofi, and Janssen, outside the submitted work.

Aims: In patients undergoing pacemaker implantation with no prior history of heart failure (HF), the presence of left bundle branch block (LBBB) has been identified as an independent predictor of HF-related death or hospitalization, while the prognostic significance of right bundle branch block (RBBB) remains uncertain. We aimed to assess the long-term risk of all-cause mortality in patients with a standard indication for permanent pacing and normal or moderately depressed left ventricular function when RBBB is detected at the time of implantation., Methods: We retrospectively enrolled 1348 consecutive patients who had undergone single- or dual-chamber pacemaker implantation at the study center, from January 1990 to December 2022. Patients with a left ventricular ejection fraction ≤35% or a prior diagnosis of HF were excluded., Results: The baseline 12-lead electrocardiogram revealed an RBBB in 241 (18%) and an LBBB in 98 (7%) patients. During a median follow-up of 65 [25th-75th percentile: 32-117] months, 704 (52%) patients died. The combined endpoint of cardiovascular death or HF hospitalization was reached by 173 (13%) patients. On multivariate analysis, RBBB was confirmed as an independent predictor of death [hazard ratio, 1.33; 95% confidence interval (CI), 1.09-1.63; P  = 0.005]. However, when considering the combined endpoint of cardiovascular death and HF hospitalization, this endpoint was independently associated with LBBB (hazard ratio, 2.13; 95% CI, 1.38-3.29; P  < 0.001), but not with RBBB., Conclusion: In patients with standard pacemaker indications and normal or moderately depressed left ventricular function, the presence of basal RBBB was an independent predictor of mortality. However, it was not associated with the combined endpoint of cardiovascular death and HF hospitalization., (Copyright © 2024 Italian Federation of Cardiology - I.F.C. All rights reserved.)

In the 2000s, cardiac resynchronization therapy (CRT) became a revolutionary treatment for heart failure with reduced left ventricular ejection fraction (HFrEF) and wide QRS. However, about one-third of CRT recipients do not show a favorable response. This review of the current literature aims to better define the concept of CRT response/nonresponse. The diagnosis of CRT nonresponder should be viewed as a continuum, and it cannot rely solely on a single parameter. Moreover, baseline features of some patients might predict an unfavorable response. A strong collaboration between heart failure specialists and electrophysiologists is key to overcoming this challenge with multiple strategies. In the contemporary era, new pacing modalities, such as His-bundle pacing and left bundle branch area pacing, represent a promising alternative to CRT. Observational studies have demonstrated their potential; however, several limitations should be addressed. Large randomized controlled trials are needed to prove their efficacy in HFrEF with electromechanical dyssynchrony., (Copyright © 2024 Heart Rhythm Society. Published by Elsevier Inc.

Atrial fibrillation (AF) may be asymptomatic and the extensive monitoring capabilities of cardiac implantable electronic devices (CIEDs) revealed asymptomatic atrial tachi-arrhythmias of short duration (minutes-hours) occurring in patients with no prior history of AF and without AF detection at a conventional surface ECG. Both the terms "AHRE" (Atrial High-Rate Episodes) and subclinical AF were used in a series of prior studies, that evidenced the association with an increased risk of stroke. Two randomized controlled studies were planned in order to assess the risk-benefit profile of anticoagulation in patients with AHRE/subclinical AF: the NOAH and ARTESiA trials. The results of these two trials (6548 patients enrolled, overall) show that the risk of stroke/systemic embolism associated with AHRE/subclinical AF is in the range of 1-1.2 % per patient-year, but with an important proportion of severe/fatal strokes occurring in non-anticoagulated patients. The apparent discordance between ARTESiA and NOAH results may be approached by considering the related study-level meta-analysis, which highlights a consistent reduction of ischemic stroke with oral anticoagulants vs. aspirin/placebo (relative risk [RR] 0.68, 95 % CI 0.50-0.92). Oral anticoagulation was found to increase major bleeding (RR 1.62, 95 % CI 1.05-2.5), but no difference was found in fatal bleeding (RR 0.79, 95 % CI 0.37-1.69). Additionally, no difference was found in cardiovascular death or all-cause mortality. Taking into account these results, clinical decision-making for patients with AHRE/subclinical AF at risk of stroke, according to CHA 2 DS 2 -VASc, can now be evidence-based, considering the benefits and related risks of oral anticoagulants, to be shared with appropriately informed patients., Competing Interests: Declaration of competing interest The authors report no conflict of interests related to the present article.

Background: The outcome implications of asymptomatic vs. symptomatic atrial fibrillation (AF) in specific groups of patients according to clinical heart failure (HF) and left ventricular ejection fraction (LVEF) need to be clarified., Methods: In a prospective observational study, patients were categorized according to overt HF with LVEF≤40 %, or with LVEF>40 %, or without overt HF with LVEF40 %≤ or > 40 %, as well as according to the presence of asymptomatic or symptomatic AF., Results: A total of 8096 patients, divided into 8 groups according to HF and LVEF, were included with similar proportions of asymptomatic AF (ranging from 43 to 48 %). After a median follow-up of 730 [699 -748] days, the composite outcome (all-cause death and MACE) was significantly worse for patients with asymptomatic AF associated with HF and reduced LVEF vs. symptomatic AF patients of the same group (p = 0.004). On adjusted Cox regression analysis, asymptomatic AF patients with HF and reduced LVEF were independently associated with a higher risk for the composite outcome (aHR 1.32, 95 % CI 1.04-1.69) and all-cause death (aHR 1.33, 95 % CI 1.02-1.73) compared to symptomatic AF patients with HF and reduced LVEF. Kaplan-Meier curves showed that HF-LVEF≤40 % asymptomatic patients had the highest cumulative incidence of all-cause death and MACE (p < 0.001 for both)., Conclusions: In a large European cohort of AF patients, the risk of the composite outcome at 2 years was not different between asymptomatic and symptomatic AF in the whole cohort but adverse implications for poor outcomes were found for asymptomatic AF in HF with LVEF≤40 %., Competing Interests: Declaration of Competing Interest The authors reported no conflict of interests related to the present article.

Aims: Electrophysiological (EP) operations that have traditionally involved long hospital lengths of stay (LOS) are now being undertaken as day case procedures. The coronavirus disease-19 pandemic served as an impetus for many centres to shorten LOS for EP procedures. This survey explores LOS for elective EP procedures in the modern era., Methods and Results: An online survey consisting of 27 multiple-choice questions was completed by 245 respondents from 35 countries. With respect to de novo cardiac implantable electronic device (CIED) implantations, day case procedures were reported for 79.5% of implantable loop recorders, 13.3% of pacemakers (PMs), 10.4% of implantable cardioverter defibrillators (ICDs), and 10.2% of cardiac resynchronization therapy (CRT) devices. With respect to CIED generator replacements, day case procedures were reported for 61.7% of PMs, 49.2% of ICDs, and 48.2% of CRT devices. With regard to ablations, day case procedures were reported for 5.7% of atrial fibrillation (AF) ablations, 10.7% of left-sided ablations, and 17.5% of right-sided ablations. A LOS ≥ 2 days for CIED implantation was reported for 47.7% of PM, 54.5% of ICDs, and 56.9% of CRT devices and for 54.5% of AF ablations, 42.2% of right-sided ablations, and 46.1% of left-sided ablations. Reimbursement (43-56%) and bed availability (20-47%) were reported to have no consistent impact on the organization of elective procedures., Conclusion: There is a wide variation in the LOS for elective EP procedures. The LOS for some procedures appears disproportionate to their complexity. Neither reimbursement nor bed availability consistently influenced LOS., Competing Interests: Conflict of interest: G.B. reported small speaker fees from Bayer, Boehringer Ingelheim, Boston, Daiichi Sankyo, Microport, Janssen, and Sanofi outside of the submitted work.

In this review we focus on heart failure (HF) which, as known, is associated with a substantial risk of hospitalizations and adverse cardiovascular outcomes, including death. In recent years, systems to monitor cardiac function and patient parameters have been developed with the aim to detect subclinical pathophysiological changes that precede worsening HF. Several patient-specific parameters can be remotely monitored through cardiac implantable electronic devices (CIED) and can be combined in multiparametric scores predicting patients' risk of worsening HF with good sensitivity and moderate specificity. Early patient management at the time of pre-clinical alerts remotely transmitted by CIEDs to physicians might prevent hospitalizations. However, it is not clear yet which is the best diagnostic pathway for HF patients after a CIED alert, which kind of medications should be changed or escalated, and in which case in-hospital visits or in-hospital admissions are required. Finally, the specific role of healthcare professionals involved in HF patient management under remote monitoring is still matter of definition. We analyzed recent data on multiparametric monitoring of patients with HF through CIEDs. We provided practical insights on how to timely manage CIED alarms with the aim to prevent worsening HF. We also discussed the role of biomarkers and thoracic echo in this context, and potential organizational models including multidisciplinary teams for remote care of HF patients with CIEDs., Competing Interests: Declaration of Competing Interest GB received small speaker's fees from Bayer, Boston, Boehringer, Daiichi Sankyo, Janssen and Sanofi, outside of the submitted work.

Background: Strategies for blood conservation, coupled with a careful preoperative assessment, may be applied to Jehovah's Witnesses (JW) patients who are candidates for cardiac surgery interventions. There is a need to assess clinical outcomes and safety of bloodless surgery in JW patients undergoing cardiac surgery., Methods: We performed a systematic review and meta-analysis of studies comparing JW patients with controls undergoing cardiac surgery. The primary endpoint was short-term mortality (in-hospital or 30-day mortality). Peri-procedural myocardial infarction, re-exploration for bleeding, pre-and postoperative Hb levels and cardiopulmonary bypass (CPB) time were also analyzed., Results: A total of 10 studies including 2,302 patients were included. The pooled analysis showed no substantial differences in terms of short-term mortality among the two groups (OR 1.13, 95% CI 0.74-1.73, I 2 =0%). There were no differences in peri-operative outcomes among JW patients and controls (OR 0.97, 95% CI 0.39-2.41, I 2 =18% for myocardial infarction; OR 0.80, 95% CI 0.51-1.25, I 2 =0% for re-exploration for bleeding). JW patients had a higher level of preoperative Hb (Standardized Mean Difference [SMD] 0.32, 95% CI 0.06-0.57) and a trend toward a higher level of postoperative Hb (SMD 0.44, 95% CI -0.01-0.90). A slightly lower CPB time emerged in JWs compared with controls (SMD -0.11, 95% CI -0.30-0.07)., Conclusions: JW patients undergoing cardiac surgery, with avoidance of blood transfusions, did not have substantially different peri-operative outcomes compared with controls, with specific reference to mortality, myocardial infarction, and re-exploration for bleeding. Our results support the safety and feasibility of bloodless cardiac surgery, applying patient blood management strategies., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Aims: To know the prevalence of atrial fibrillation (AF), as well as the incidence of postoperative AF (POAF) in vascular surgery for arterial diseases and its outcome implications., Methods: We performed a systematic review and meta-analysis following the PRISMA statement., Results: After the selection process, we analyzed 44 records (30 for the prevalence of AF history and 14 for the incidence of POAF).The prevalence of history of AF was 11.5% [95% confidence interval (CI) 1-13.3] with high heterogeneity (I2 = 100%). Prevalence was higher in the case of endovascular procedures. History of AF was associated with a worse outcome in terms of in-hospital death [odds ratio (OR) 3.29; 95% CI 2.66-4.06; P < 0.0001; I2 94%] or stroke (OR 1.61; 95% CI 1.39-1.86; P < 0.0001; I2 91%).The pooled incidence of POAF was 3.6% (95% CI 2-6.4) with high heterogeneity (I2 = 100%). POAF risk was associated with older age (mean difference 4.67 years, 95% CI 2.38-6.96; P = 0.00007). The risk of POAF was lower in patients treated with endovascular procedures as compared with an open surgical procedure (OR 0.35; 95% CI 0.13-0.91; P = 0.03; I2 = 61%)., Conclusions: In the setting of vascular surgery for arterial diseases a history of AF is found overall in 11.5% of patients, more frequently in the case of endovascular procedures, and is associated with worse outcomes in terms of short-term mortality and stroke.The incidence of POAF is overall 3.6%, and is lower in patients treated with an endovascular procedure as compared with open surgery procedures. The need for oral anticoagulants for preventing AF-related stroke should be evaluated with randomized clinical trials., (Copyright © 2023 Italian Federation of Cardiology - I.F.C.

Aims: The differentiation of left ventricular (LV) hypertrophic phenotypes is challenging in patients with normal ejection fraction (EF). The myocardial contraction fraction (MCF) is a simple dimensionless index useful for specifically identifying cardiac amyloidosis (CA) and hypertrophic cardiomyopathy (HCM) when calculated by cardiac magnetic resonance. The purpose of this study was to evaluate the value of MCF measured by three-dimensional automated, machine-learning-based LV chamber metrics (dynamic heart model [DHM]) for the discrimination of different forms of hypertrophic phenotypes. Methods and Results: We analyzed the DHM LV metrics of patients with CA ( n = 10), hypertrophic cardiomyopathy (HCM, n = 36), isolated hypertension (IH, n = 87), and 54 healthy controls. MCF was calculated by dividing LV stroke volume by LV myocardial volume. Compared with controls (median 61.95%, interquartile range 55.43-67.79%), mean values for MCF were significantly reduced in HCM-48.55% (43.46-54.86% p < 0.001)-and CA-40.92% (36.68-46.84% p < 0.002)-but not in IH-59.35% (53.22-64.93% p < 0.7). MCF showed a weak correlation with EF in the overall cohort (R 2 = 0.136) and the four study subgroups (healthy adults, R 2 = 0.039 IH, R 2 = 0.089; HCM, R 2 = 0.225; CA, R 2 = 0.102). ROC analyses showed that MCF could differentiate between healthy adults and HCM (sensitivity 75.9%, specificity 77.8%, AUC 0.814) and between healthy adults and CA (sensitivity 87.0%, specificity 100%, AUC 0.959). The best cut-off values were 55.3% and 52.8%. Conclusions: The easily derived quantification of MCF by DHM can refine our echocardiographic discrimination capacity in patients with hypertrophic phenotype and normal EF. It should be added to the diagnostic workup of these patients.

Aims: The HeartLogic Index combines data from multiple implantable cardioverter defibrillators (ICDs) sensors and has been shown to accurately stratify patients at risk of heart failure (HF) events. We evaluated and compared the performance of this algorithm during sinus rhythm and during long-lasting atrial fibrillation (AF)., Methods and Results: HeartLogic was activated in 568 ICD patients from 26 centres. We found periods of ≥30 consecutive days with an atrial high-rate episode (AHRE) burden <1 h/day and periods with an AHRE burden ≥20 h/day. We then identified patients who met both criteria during the follow-up (AHRE group, n = 53), to allow pairwise comparison of periods. For control purposes, we identified patients with an AHRE burden <1 h throughout their follow-up and implemented 2:1 propensity score matching vs. the AHRE group (matched non-AHRE group, n = 106). In the AHRE group, the rate of alerts was 1.2 [95% confidence interval (CI): 1.0-1.5]/patient-year during periods with an AHRE burden <1 h/day and 2.0 (95% CI: 1.5-2.6)/patient-year during periods with an AHRE-burden ≥20 h/day (P = 0.004). The rate of HF hospitalizations was 0.34 (95% CI: 0.15-0.69)/patient-year during IN-alert periods and 0.06 (95% CI: 0.02-0.14)/patient-year during OUT-of-alert periods (P < 0.001). The IN/OUT-of-alert state incidence rate ratio of HF hospitalizations was 8.59 (95% CI: 1.67-55.31) during periods with an AHRE burden <1 h/day and 2.70 (95% CI: 1.01-28.33) during periods with an AHRE burden ≥20 h/day. In the matched non-AHRE group, the rate of HF hospitalizations was 0.29 (95% CI: 0.12-0.60)/patient-year during IN-alert periods and 0.04 (95% CI: 0.02-0.08)/patient-year during OUT-of-alert periods (P < 0.001). The incidence rate ratio was 7.11 (95% CI: 2.19-22.44)., Conclusion: Patients received more alerts during periods of AF. The ability of the algorithm to identify increased risk of HF events was confirmed during AF, despite a lower IN/OUT-of-alert incidence rate ratio in comparison with non-AF periods and non-AF patients., Clinical Trial Registration: http://clinicaltrials.gov/Identifier: NCT02275637., Competing Interests: Conflict of interest: G.B. reported small speaker fees from Bayer, Boehringer Ingelheim, Boston, Daiichi Sankyo, Janssen, and Sanofi outside of the submitted work.

There is increasing concern regarding impact of clinical complexity in patients with atrial fibrillation (AF). We explored the impact of different clinical complexity features in AF patients. We analyzed patients from a prospective, observational, multicenter Europe-wide AF registry. Features of clinical complexity among patients with CHA 2 DS 2 -VASc ≥2 were: (1) history of bleeding; (2) frailty; (3) chronic kidney disease (CKD); (4) ≥2 features. A total of 10,169 patients were analyzed. Of these, 141 (1.4%) had history of bleeding, 954 (9.4%) were frail, 1767 (17.4%) had CKD and 1253 (12.3%) had ≥2 features. All features of clinical complexity were less treated with OAC. History of bleeding (HR 1.94, 95% CI 1.32-2.85), frailty (HR 1.38, 95% CI 1.11-1.71), CKD (HR 1.50, 95% 1.28-1.75) and ≥2 features (HR 2.08, 95% CI 1.73-2.51) were associated with outcomes. Presence of features of clinical complexity is associated with lower use of OAC and higher risk of outcomes., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

Background: The European Society of Cardiology (ESC) clinical practice guidelines are essential tools for decision-making., Aim: To analyze the level of evidence (LOE) and the class of recommendations in the ESC guidelines released in the last 12 years., Methods: We evaluated 50 ESC guidelines released from 2011 to 2022, related to 27 topics and categorized them into seven macro-groups. We analyzed every recommendation in terms of LOE and class of recommendation, calculating their relative proportions and changes over time in consecutive editions of the same guideline., Results: A total of 6972 recommendations were found, with an increase in number per year over time. Among the 50 ESC guidelines, the proportional distribution of classes of recommendations was 49% for Class I, 29% for Class IIa, 15% for Class IIb, and 8% for Class III. Overall, 16% of the recommendations were classified as LOE A, 31% LOE B and 53% LOE C. The field of preventive cardiology had the largest proportion of LOE A, while the lowest was in the field of valvular, myocardial, pericardial and pulmonary diseases. The overall proportion of LOE A recommendations in the most recent guidelines compared to their prior versions increased from 17% to 20%., Conclusions: The recommendations included in the ESC guidelines widely differ in terms of quality of evidence, with only 16% supported by the highest quality of evidence. Although a slight global increase in LOE A recommendations was observed in recent years, further scientific research efforts are needed to increase the quality of evidence., Competing Interests: Declaration of Competing Interest The authors reported no conflict of interests related to the present article.

Background: A smartphone 12-Lead ECG that enables layman ECG screening is still lacking. We aimed to validate D-Heart ECG device, a smartphone 8/12 Lead electrocardiograph with an image processing algorithm to guide secure electrode placement by non-professional users., Methods: One-hundred-fourty-five patients with HCM were enrolled. Two uncovered chest images were acquired using the smartphone camera. An image with virtual electrodes placement by imaging processing algorithm software was compared to the 'gold standard' electrode placement by a doctor. D-Heart 8 and 12-Lead ECG were obtained, immediately followed by 12‑lead ECGs and were assessed by 2 independent observers. Burden of ECG abnormalities was defined by a score based on the sum of 9 criteria, identifying four classes of increasing severity., Results: A total of 87(60%) patients presented a normal/mildly abnormal ECG, whereas 58(40%) had moderate or severe ECG alteration. Eight(6%) patients had ≥1 misplaced electrode. D-Heart 8-Lead and 12‑lead ECGs concordance according to Cohen's weighted kappa test was 0,948 (p < 0,001, agreement of 97.93%). Concordance was high for the Romhilt-Estes score (k w  = 0,912; p < 0.01). Concordance between D-Heart 12-Lead ECG and standard 12-Lead ECG was perfect (k w  = 1). PR and QRS intervals measurements comparison with Bland-Altman method showed good accuracy (95% limit of agreement ±18 ms for PR and ± 9 ms for QRS)., Conclusions: D-Heart 8/12-Lead ECGs proved accurate, allowing an assessment of ECG abnormalities comparable to the standard 12‑lead ECG in patients with HCM. The image processing algorithm provided accurate electrode placement, standardizing exam quality, potentially opening perspectives for layman ECG screening campaigns., (Copyright © 2023.

Aim: Atrial fibrillation is a multifaceted disease requiring personalized treatment, in accordance with current ESC guidelines. Despite a wide range of literature, we still have various aspects dividing the opinion of the experts in rate control, rhythm control and thromboembolic prophylaxis. The aim of this survey was to provide a country-wide picture of current practice regarding atrial fibrillation pharmacological management according to a patient's characteristics., Methods: Data were collected using an in-person survey that was administered to members of the Italian Association of Arrhythmology and Cardiac Pacing., Results: We collected data from 106 physicians, working in 72 Italian hospitals from 15 of 21 regions. Our work evidenced a high inhomogeneity in atrial fibrillation management regarding rhythm control, rate control and thromboembolic prophylaxis in both acute and chronic patients. This element was more pronounced in settings in which literature shows a lack of evidence and, consequently, the indications provided by the guidelines are weak or absent., Conclusion: This National survey evidenced a high inhomogeneity in current approaches adopted for atrial fibrillation management by a sample of Italian cardiologist experts in arrhythmia management. Further studies are needed to explore if these divergences are associated with different long-term outcomes., (Copyright © 2023 Italian Federation of Cardiology - I.F.C. All rights reserved.)

Background: The incidence of infections and death in patients implanted with cardiac implantable electronic devices (CIEDs) is not fully known yet., Aim: To describe the incidence of CIED-related infection and death, and their potential predictors in a contemporary cohort of CIED patients., Methods: All consecutive patients implanted with a CIED at our institution were prospectively enrolled. Follow-up visits were performed 2 weeks after CIED implantation for all patients, and then every 6 months for implantable cardioverter defibrillator (ICD)/cardiac resynchronization therapy (CRT) patients and every 12 months for pacemaker (PM) patients. The adjudication of CIED-related infections was performed by two independent investigators and potential disagreement was resolved by a senior investigator., Results: Between September 2016 and August 2020, a total of 838 patients were enrolled (34.6% female; median age 77 (69.6-83.6); median PADIT score 2 (2-4)). PMs were implanted in 569 (68%) patients and ICD/CRT in 269 (32%) patients. All patients had pre-implant antibiotic prophylaxis and 5.5% had an antibiotic-eluting envelope. Follow-up data were available for 832 (99.2%) patients. After a median follow-up of 42.3 (30.2-56.4) months, five (0.6%) patients had a CIED-related infection and 212 (25.5%) patients died. Using multivariate Cox regression analysis, end-stage chronic kidney disease (CKD) requiring dialysis and therapy with corticosteroids was independently associated with a higher risk of infection (hazard ratio (HR): 14.20; 95% confidence interval (CI) 1.48-136.62 and HR: 14.71; 95% CI 1.53-141.53, respectively). Age (HR: 1.07; 95% CI 1.05-1.09), end-stage CKD requiring dialysis (HR: 6.13; 95% CI 3.38-11.13) and history of atrial fibrillation (HR: 1.47; 95% CI 1.12-1.94) were independently associated with all-cause death., Conclusions: In a contemporary cohort of CIED patients, mortality was substantially high and associated with clinical factors depicting a population at risk. On the other hand, the incidence of CIED-related infections was low.

Atrial fibrillation (AF) is the most prevalent arrhythmia worldwide. The presence of AF is associated with increased risk of systemic thromboembolism, but with the uptake of oral anticoagulant (OAC) and implementation of a holistic and integrated care management, this risk is substantially reduced. The diagnosis of AF requires a 30-s-long electrocardiographic (ECG) trace, irrespective of the presence of symptoms, which may represent the main indication for an ECG tracing. However, almost half patients are asymptomatic at the time of incidental AF diagnosis, with similar risk of stroke of those with clinical AF. This has led to a crucial role of screening for AF, to increase the diagnosis of population at risk of clinical events. The aim of this review is to give a comprehensive overview about the epidemiology of asymptomatic AF, the different screening technologies, the yield of diagnosis in asymptomatic population, and the benefit derived from screening in terms of reduction of clinical adverse events, such as stroke, cardiovascular, and all-cause death. We aim to underline the importance of implementing AF screening programmes and reporting about the debate between scientific societies' clinical guidelines recommendations and the concerns expressed by the regulatory authorities, which still do not recommend population-wide screening. This review summarizes data on the ongoing trials specifically designed to investigate the benefit of screening in terms of risk of adverse events which will further elucidate the importance of screening in reducing risk of outcomes and influence and inform clinical practice in the next future., Competing Interests: Conflict of interest: G.F.R. reports consultancy for Boehringer Ingelheim and an educational grant from Anthos, outside the submitted work.

Introduction: VDD pacing system was introduced more than 30 years ago. Its use is considered by the 2021 European Society of Cardiology guidelines on cardiac pacing as a potential alternative to dual chambers system for patients with atrioventricular block and normal sinus node function., Areas Covered: In this article, we performed a narrative review of current literature in order to identify the strengths and weaknesses of this pacing system. VDD system allows the maintenance of AV synchronous pacing and its hemodynamic advantages. Some disadvantages may be related to the non-negligible incidence of atrial undersensing and the possible subsequent need for upgrade to DDD system. On the other hand, shorter implantation time and lower complications rate may be advantages., Expert Opinion: In the modern pacing era, VDD pacing system struggles to find its own space. However, it may still be considered as a valuable alternative to a dual-chamber pacemaker for selected patients, in specific clinical scenarios.

Aims: Adherence to guideline-directed oral anticoagulation (OAC) in patients with atrial fibrillation (AF) improves outcomes, but limited data are available from China. We evaluated the adherence to guideline-directed anticoagulation and its impact on clinical outcomes in a high-risk cohort of elderly Chinese patients., Methods and Results: The Optimal Thromboprophylaxis in Elderly Chinese Patients with Atrial Fibrillation (ChiOTEAF) registry is a prospective, multicentre study conducted from October 2014 to December 2018. Endpoints of interest were all-cause death, thromboembolic (TE) events and major bleedings in patients with a guideline-directed indication for OACs (CHA2DS2-VASc ≥1 if male or ≥2 if female). The eligible cohort consisted of 5742 patients, of whom 2567 (44.7%) patients were treated with an OAC. Seven independent predictors of OAC undertreatment were identified: age [odds ratio (OR): 1.04; 95% confidence interval (CI): 1.03-1.05; P < 0.001], first diagnosed AF (OR: 1.71; 95%CI: 1.44-2.03; P < 0.001), chronic kidney disease (OR: 1.67; 95%CI: 1.36-2.06; P < 0.001), liver disease (OR: 1.69; 95%CI: 1.19-2.41; P = 0.003), dementia (OR: 1.67; 95%CI: 1.06-2.64; P = 0.026), prior extracranial bleeding (OR: 1.89; 95%CI: 1.35-2.64; P < 0.001), and the use of antiplatelet drug (OR: 6.97; 95%CI: 5.89-8.23; P < 0.001). On multivariate analysis, OAC undertreatment was significantly associated with a higher risk all-cause death (OR: 3.79; 95%CI: 2.61-5.53; P < 0.001) and TE events (OR: 2.28; 95%CI: 1.39-3.72; P = 0.001), and a similar risk of major bleeding as compared with guideline-directed OAC therapy., Conclusion: Only 44.7% of all eligible patients were prescribed OAC in accordance with guideline recommendations. The independent predictors for OAC undertreatment were age, first diagnosed AF, chronic kidney disease, chronic obstructive pulmonary disease, prior extracranial bleeding, and the use of the antiplatelet drugs. Guideline-adherent thromboprophylaxis was safe and may be associated with improved survival and less TE among elderly Chinese patients with AF., (© The Author(s) 2021.

Background: The prevalence of acute cardiovascular diseases (CVDs) in cancer patients is steadily increasing and represents a significant reason for admission to the emergency department (ED)., Methods: We conducted a prospective observational study, enrolling consecutive patients with cancer presenting to a tertiary oncological ED and consequently admitted to the oncology ward. Two groups of patients were identified based on main symptoms that lead to ED presentation: symptoms potentially related to CVD vs. symptoms potentially not related to CVD. The aims of the study were to describe the prevalence of symptoms potentially related to CVD in this specific setting and to evaluate the prevalence of definite CV diagnoses at discharge. Secondary endpoints were new intercurrent in-hospital CV events occurrence, length of stay in the oncology ward, and mid-term mortality for all-cause., Results: A total of 469 patients (51.8% female, median age 68.0 [59.1-76.3]) were enrolled. One hundred and eighty-six out of 469 (39.7%) presented to the ED with symptoms potentially related to CVD. Baseline characteristics were substantially similar between the two study groups. A discharge diagnosis of CVD was confirmed in 24/186 (12.9%) patients presenting with symptoms potentially related to CVD and in no patients presenting without symptoms potentially related to CVD ( p < 0.01). During a median follow-up of 3.4 (1.2-6.5) months, 204 (43.5%) patients died (incidence rate of 10.1 per 100 person/months). No differences were found between study groups in terms of all-cause mortality (hazard ratio [HR]: 0.85, 95% confidence interval [CI] 0.64-1.12), new in-hospital CV events (HR: 1.03, 95% CI 0.77-1.37), and length of stay ( p = 0.57)., Conclusions: In a contemporary cohort of cancer patients presenting to a tertiary oncological ED and admitted to an oncology ward, symptoms potentially related to CVD were present in around 40% of patients, but only a minority were actually diagnosed with an acute CVD.

Background: Paroxysmal atrial fibrillation (AF) may often progress towards more sustained forms of the arrhythmia, but further research is needed on the factors associated with this clinical course., Methods: We analyzed patients enrolled in a prospective cohort study of AF patients. Patients with paroxysmal AF at baseline or first-detected AF (with successful cardioversion) were included. According to rhythm status at 1 year, patients were stratified into: (i) No AF progression and (ii) AF progression. All-cause death was the primary outcome., Results: A total of 2688 patients were included (median age 67 years, interquartile range 60-75, females 44.7%). At 1-year of follow-up, 2094 (77.9%) patients showed no AF progression, while 594 (22.1%) developed persistent or permanent AF. On multivariable logistic regression analysis, no physical activity (odds ratio [OR] 1.35, 95% CI 1.02-1.78), valvular heart disease (OR 1.63, 95% CI 1.23-2.15), left atrial diameter (OR 1.03, 95% CI 1.01-1.05), or left ventricular ejection fraction (OR 0.98, 95% CI 0.97-1.00) were independently associated with AF progression at 1 year. After the assessment at 1 year, the patients were followed for an extended follow-up of 371 days, and those with AF progression were independently associated with a higher risk for all-cause death (adjusted hazard ratio 1.77, 95% CI 1.09-2.89) compared to no-AF-progression patients., Conclusions: In a contemporary cohort of AF patients, a substantial proportion of patients presenting with paroxysmal or first-detected AF showed progression of the AF pattern within 1 year, and clinical factors related to cardiac remodeling were associated with progression. AF progression was associated with an increased risk of all-cause mortality.

Background: The number of patients with cardiac implantable electronic devices (CIEDs) undergoing radiotherapy (RT) for cancer treatment is growing. At present, prevalence and predictors of RT-induced CIEDs malfunctions are not defined., Methods: Systematic review and meta-analysis conducted following the PRISMA recommendations. PubMed, Scopus and Google Scholar were searched from inception to 31/01/2022 for studies reporting RT-induced malfunctions in CIEDs patients. Aim was to assess the prevalence of RT-induced CIEDs malfunctions and identify potential predictors., Results: Thirty-two out of 3962 records matched the inclusion criteria and were included in the meta-analysis. A total of 135 CIEDs malfunctions were detected among 3121 patients (6.6%, 95% confidence interval [CI]: 5.1%-8.4%). The pooled prevalence increased moving from pacemaker (PM) to implantable cardioverter defibrillator (ICD), and cardiac resynchronization therapy and defibrillator (CRT-D) groups (4.1%, 95% CI: 2.9-5.8; 8.2% 95% CI: 5.9-11.3; and 19.8%, 95% CI: 11.4-32.2 respectively). A higher risk ratio (RR) of malfunctions was found when neutron-producing energies were used as compared to non-neutron-producing energies (RR 9.98, 95% CI: 5.09-19.60) and in patients with ICD/CRT-D as compared to patients with PM/CRT-P (RR 2.07, 95% CI: 1.40-3.06). On the contrary, no association was found between maximal radiation dose at CIED >2 Gy and CIEDs malfunctions (RR 0.93; 95% CI: 0.31-2.76)., Conclusions: Radiotherapy related CIEDs malfunction had a prevalence ranging from 4% to 20%. The use of neutron-producing energies and more complex devices (ICD/CRT-D) were associated with higher risk of device malfunction, while the radiation dose at CIED did not significantly impact on the risk unless higher doses (>10 Gy) were used., (© 2022 The Authors.

Cardiac surgery in Jehovah's Witnesses (JW) patients who refuse blood transfusion is challenging requiring dedicated strategies. We aimed to analyze non-selected JW patients undergoing cardiac surgery and to compare with matched controls both perioperative outcomes and long-term survival. We retrospectively analyzed JW patients undergoing cardiac surgery from January 2016 to March 2021 and compared them with matched controls. The primary outcome was a composite of in-hospital perioperative adverse events and in-hospital mortality. The secondary outcome was all-cause mortality at long-term follow-up. A total of 113 JW patients and 113 controls were included. Baseline clinical characteristics, including laboratory parameters were comparable. Overall, there were no statistical differences between JW vs controls in terms of in-hospital mortality (2.7% vs 1.8%, p = 1.00) but mortality was remarkably high (40%) in JW patients with post-op hemoglobin < 8 g/dl. Logistic regression analysis found that the JW group was not associated with a higher occurrence of the composite outcome (adjusted odds ratio 0.91, 95% confidence interval [CI] 0.54-1.57). After a median follow-up of 1397 [IQR 922.7-1723.5] days, JW patients were not associated with a significantly higher all-cause mortality (adjusted hazard ratio 0.77, 95% CI 0.24-2.42). Cardiac surgery can be safely performed in non-anemic JW patients despite the refusal of blood transfusions. Favorable clinical outcomes can be achieved by the use of specific perioperative strategies for bloodless surgery with no differences as compared to control patients except in JW patients with a very low level of post-operative hemoglobin not supported by immediate transfusions., (© 2022.

Background: Telemedicine requires either the use of digital tools or a minimum technological knowledge of the patients. Digital health literacy may influence the use of telemedicine in most patients, particularly those with frailty. We aimed to explore the association between frailty, the use of digital tools, and patients' digital health literacy., Methods: We prospectively enrolled patients referred to arrhythmia outpatient clinics of our cardiology department from March to September 2022. Patients were divided according to frailty status as defined by the Edmonton Frail Scale (EFS) into robust, pre-frail, and frail. The degree of digital health literacy was assessed through the Digital Health Literacy Instrument (DHLI), which explores seven digital skill categories measured by 21 self-report questions., Results: A total of 300 patients were enrolled (36.3% females, median age 75 (66-84)) and stratified according to frailty status as robust (EFS ≤ 5; 70.7%), pre-frail (EFS 6-7; 15.7%), and frail (EFS ≥ 8; 13.7%). Frail and pre-frail patients used digital tools less frequently and accessed the Internet less frequently compared to robust patients. In the logistic regression analysis, frail patients were significantly associated with the non-use of the Internet (adjusted odds ratio 2.58, 95% CI 1.92-5.61) compared to robust and pre-frail patients. Digital health literacy decreased as the level of frailty increased in all the digital domains examined., Conclusions: Frail patients are characterized by lower use of digital tools compared to robust patients, even though these patients would benefit the most from telemedicine. Digital skills were strongly influenced by frailty.

Remote monitoring (RM) of cardiac implantable electrical devices (CIEDs) is currently proposed as a standard of care for CIEDs follow-up, as recommended by major cardiology societies worldwide. By detecting a series of relevant device and patient-related parameters, RM is a valuable option for early detection of CIEDs' technical issues, as well as changes in parameters related to cardio-respiratory functions. Moreover, RM may allow longer spacing between in-office follow-ups and better organization of in-hospital resources. Despite these potential advantages, resulting in improved patient safety, we are still far from a widespread diffusion of RM across Europe. Reimbursement policies across Europe still show an important heterogeneity and have been considered as an important barrier to full implementation of RM as a standard for the follow-up of all the patients with pacemakers, defibrillators, devices for cardiac resynchronization, or implantable loop recorders. Indeed, in many countries, there are still inertia and unresponsiveness to the request for widespread implementation of RM for CIEDs, although an improvement was found in some countries as compared to years ago, related to the provision of some form of reimbursement. As a matter of fact, the COVID-19 pandemic has promoted an increased use of digital health for connecting physicians to patients, even if digital literacy may be a limit for the widespread implementation of telemedicine. CIEDs have the advantage of making possible RM with an already defined organization and reliable systems for data transmissions that can be easily implemented as a standard of care for present and future cardiology practice., Competing Interests: Conflict of interest: G.B. received small speaker's fees from Medtronic, Boston, Boehringer, and Bayer outside of the submitted work.

Background: The aim of this study was to determine the impact of transcatheter edge-to-edge repair (TEER) on left and right ventricular (LV, RV) and left and right atrial (LA, RA) remodeling according to the mechanism of mitral regurgitation (MR) and history of atrial fibrillation (AF)., Methods: Twenty-four patients (mean age 78.54 years ± 7.64 SD; 62.5% males) underwent TEER at our center. All the patients underwent echocardiography 1.6 ± 0.9 months before the procedure and after 5.7 ± 3.5 months; functional MR accounted for 54% of cases., Results: Compared to baseline, a statistically significant improvement in LV end-diastolic diameter (LVEDD), LV indexed mass (ILVM), LV end-diastolic and end-systolic volumes (LVEDV, LVESV), indexed LA volume (iLAV), and morpho-functional RV parameters was recorded. LVEDD and LVEDV improved in primary MR cohort, whereas in secondary MR, a significant reduction in LVEDV and LVESV was found without a significant functional improvement. LA reverse remodeling was found in organic MR with a trend toward ameliorated function. Furthermore, a significant reduction of LA volumetry was detected only in patients without history of AF (AF baseline 51.4 mL/m 2 IQR 45.6-62.5 mL/m 2 f-u 48.9 mL/m 2 IQR 42.9-59.2 mL/m 2 ; p = 0.101; no AF baseline 43.5 mL/m 2 IQR 34.2-60.5 mL/m 2 f-u 42.0 mL/m 2 IQR 32.0-46.2 mL/m 2 ; p = 0.012). As regards right sections, the most relevant reverse remodeling was obtained in patients with functional MR with a baseline poorer RV function and more severe RA and RV dilation., Conclusion: TEER induces reverse remodeling involving both left and right chambers at mid-term follow-up. To deliver a tailored intervention, MR mechanism and history of AF should be considered in view of the impact on remodeling process.

Background: Implementation of the Atrial fibrillation Better Care (ABC) pathway is recommended by guidelines on atrial fibrillation (AF), but the impact of adherence to ABC pathway in patients with cancer is unknown., Objectives: To investigate the adherence to ABC pathway and its impact on adverse outcomes in AF patients with cancer., Methods: Patients enrolled in the EORP-AF General Long-Term Registry were analyzed according to (i) No Cancer; and (ii) Prior or active cancer and stratified in relation to adherence to the ABC pathway. The composite Net Clinical Outcome (NCO) of all-cause death, major adverse cardiovascular events and major bleeding was the primary endpoint., Results: Among 6550 patients (median age 69 years, females 40.1%), 6005 (91.7%) had no cancer, while 545 (8.3%) had a diagnosis of active or prior cancer at baseline, with the proportions of full adherence to ABC pathway of 30.6% and 25.7%, respectively. Adherence to the ABC pathway was associated with a significantly lower occurrence of the primary outcome vs. non-adherence, both in 'no cancer' and 'cancer' patients [adjusted Hazard Ratio (aHR) 0.78, 95% confidence interval (CI): 0.66-0.92 and aHR 0.59, 95% CI 0.37-0.96, respectively]. Adherence to a higher number of ABC criteria was associated with a lower risk of the primary outcome, being lowest when 3 ABC criteria were fulfilled (no cancer: aHR 0.54, 95%CI: 0.36-0.81; with cancer: aHR 0.32, 95% CI 0.13-0.78)., Conclusion: In AF patients with cancer enrolled in the EORP-AF General Long-Term Registry, adherence to ABC pathway was sub-optimal.

Aims: To evaluate the quality measures and clinical performance indicators among elderly Chinese patients with atrial fibrillation (AF). The management of patients with AF requires a holistic, multidisciplinary approach. Quality indicators have been proposed to assess the quality of care in 'real-world' clinical practice when managing patients with AF., Methods and Results: The Optimal Thromboprophylaxis in Elderly Chinese Patients with Atrial Fibrillation (ChiOTEAF) registry is a prospective, observational, large-scale multicentre registry conducted between October 2014 and December 2018 in China. Data were collected at the enrolment and during the follow-up visits by the local investigators. In the ChiOTEAF registry, 14 primary and 8 secondary indicators from six domains of care were assessed. Six thousand four hundred twenty patients who completed the 1-year follow-up were included in the analysis. Median age was 76 years, and the majority of patients was male (60.8%). Overall, 3246 patients (54.8%) were not treated with oral anticoagulants (OACs) appropriate to their risk of stroke; specifically, among those at highest risk of stroke, OACs were prescribed in only 43.3% patients (1258/2905). Among patients with permanent AF, 32 (3.6%) were prescribed antiarrhythmic drugs, and among those with paroxysmal AF, catheter ablation was performed in 20.7%. Patients were overburdened with multi-morbidities, including hypertension, diabetes mellitus, obesity, and sleep apnoea. During 1-year follow-up, 435 deaths (6.8%) and 89 thromboembolic events (1.4%) occurred. Patient-reported outcomes showed that 55% of patients had indicators of reduced quality of life., Conclusion: Assessment of quality indicators revealed the gaps in AF care among Chinese patients, highlighting the need for a more integrated or holistic approach to AF management., (© The Author(s) 2021.
