Introduction: The novel Confirm Rx™ implantable cardiac monitor (ICM) with SharpSense™ technology incorporates a new P‐wave discriminator designed to improve AF detection. This study aimed to evaluate the diagnostic performance of the Confirm Rx™ ICM in detecting AF episodes of varying durations. Methods: We conducted a multicenter retrospective analysis of consecutive patients implanted with a Confirm Rx™ ICM (v1.2) across nine UK hospitals, all with documented AF lasting at least 6 min. Electrocardiograms (ECGs) were manually adjudicated by cardiologists. To account for intra‐ and inter‐reviewer variability, a random sample of 10% of ECGs underwent additional review. Disagreements were resolved by a third reviewer. Diagnostic performance was determined by calculating the gross and patient‐averaged positive predictive value (PPV) for AF episodes of different duration. The source of false positive (FP) detection was also categorized. Results: Overall, 16,230 individual ECGs from 232 patients were included. The median AF episode duration was 14 min. R‐wave amplitude remained stable during follow‐up (0.52 ± 0.27 mV [initial] vs. 0.54 ± 0.29 mV [end of follow‐up], p =.10). The gross and patient‐averaged PPV were 75.0% and 67.0%, respectively. Diagnostic performance (gross) increased with progressively longer AF episodes: 88.0% for ≥1 h, 97.3% for 6 h, and 100% for 24 h. The main source of FP during tachycardia was T‐wave oversensing (54.2%), while in non‐tachycardic episodes it was predominantly ectopy (71.2%). The AF burden precision was excellent (93.3%). Conclusion: The Confirm Rx™ ICM diagnostic performance was modest for all AF episodes (75%), with accuracy increasing for longer AF episodes. [ABSTRACT FROM AUTHOR]

Aims: The COVID‐19 pandemic disrupted the delivery of care for patients with heart failure (HF), leading to fewer HF hospitalizations and increased mortality. However, nationwide data on quality of care and long‐term outcomes across the pandemic are scarce. Methods and results: We used data from the National Heart Failure Audit (NHFA) linked to national records for hospitalization and deaths. We compared pre‐COVID (2018–2019), COVID (2020), and late/post‐COVID (2021–2022) periods. Data for 227 250 patients admitted to hospital with HF were analysed and grouped according to the admission year and the presence of HF with (HFrEF) or without reduced ejection fraction (non‐HFrEF). The median age at admission was 81 years (interquartile range 72–88), 55% were men (n = 125 975), 87% were of white ethnicity (n = 102 805), and 51% had HFrEF (n = 116 990). In‐hospital management and specialized cardiology care were maintained throughout the pandemic with an increasing percentage of patients discharged on disease‐modifying medications over time (p < 0.001). Long‐term outcomes improved over time (hazard ratio [HR] 0.92, 95% confidence interval [CI] 0.90–0.95, p < 0.001), mainly driven by a reduction in cardiovascular death. Receiving specialized cardiology care was associated with better long‐term outcomes both for those who had HFrEF (HR 0.79, 95% CI 0.77–0.82, p < 0.001) and for those who had non‐HFrEF (HR 0.87, 95% CI 0.85–0.90, p < 0.001). Conclusions: Despite the disruption of healthcare systems, the clinical characteristics of patients admitted with HF were similar and the overall standard of care was maintained throughout the pandemic. Long‐term survival of patients hospitalized with HF continued to improve after COVID‐19, especially for HFrEF. [ABSTRACT FROM AUTHOR]

After due deliberation, the Task Force decided to update recommendations for the following sections of the 2021 ESC HF Guidelines: Chronic HF: HF with mildly reduced ejection fraction (HFmrEF) and HFpEF Acute HF Comorbidities and prevention of HF. 3. HF events were defined as HF hospitalizations, urgent HF visits, and unplanned outpatient HF visits. Acute heart failure Treatment of acute HF was outlined in the recent 2021 ESC HF Guidelines and a Heart Failure Association scientific statement on HF.[1],[25] Since these publications, trials have been conducted with diuretics, as well as on management strategies for patients with acute HF.
