BACKGROUND: Subclinical atrial fibrillation is short-lasting and asymptomatic and can usually be detected only by long-term continuous monitoring with pacemakers or defibrillators. Subclinical atrial fibrillation is associated with an increased risk of stroke by a factor of 2.5; however, treatment with oral anticoagulation is of uncertain benefit. METHODS: We conducted a trial involving patients with subclinical atrial fibrillation lasting 6 minutes to 24 hours. Patients were randomly assigned in a double-blind, double-dummy design to receive apixaban at a dose of 5 mg twice daily (2.5 mg twice daily when indicated) or aspirin at a dose of 81 mg daily. The trial medication was discontinued and anticoagulation started if subclinical atrial fibrillation lasting more than 24 hours or clinical atrial fibrillation developed. The primary efficacy outcome, stroke or systemic embolism, was assessed in the intention-to-treat population (all the patients who had undergone randomization); the primary safety outcome, major bleeding, was assessed in the on-treatment population (all the patients who had undergone randomization and received at least one dose of the assigned trial drug, with follow-up censored 5 days after permanent discontinuation of trial medication for any reason). RESULTS: We included 4012 patients with a mean (±SD) age of 76.8±7.6 years and a mean CHA2DS2-VASc score of 3.9±1.1 (scores range from 0 to 9, with higher scores indicating a higher risk of stroke); 36.1% of the patients were women. After a mean follow-up of 3.5±1.8 years, stroke or systemic embolism occurred in 55 patients in the apixaban group (0.78% per patient-year) and in 86 patients in the aspirin group (1.24% per patient-year) (hazard ratio, 0.63; 95% confidence interval [CI], 0.45 to 0.88; P = 0.007). In the on-treatment population, the rate of major bleeding was 1.71% per patient-year in the apixaban group and 0.94% per patient-year in the aspirin group (hazard ratio, 1.80; 95% CI, 1.26 to 2.57; P = 0.001). Fatal bleeding occurred in 5 patients in the apixaban group and 8 patients in the aspirin group. CONCLUSIONS: Among patients with subclinical atrial fibrillation, apixaban resulted in a lower risk of stroke or systemic embolism than aspirin but a higher risk of major bleeding.

OBJECTIVES: To investigate 4-year, post-transcatheter aortic valve implantation (TAVI) survival and predictors of survival by sex, in a real-world cohort that underwent transfemoral TAVI with SAPIEN 3 transcatheter heart valve. BACKGROUND: Previous TAVI investigations of first-generation devices demonstrated an early- to mid-term survival advantage in women compared with men. METHODS: SOURCE 3 (SAPIEN 3 Aortic Bioprosthesis European Outcome) is a post-approval, multicentre, observational registry. Patients (N = 1,694, 49.2% women, age 81.7 ± 6.7 years) with severe aortic stenosis and high surgical risk (logistic EuroSCORE 17.8%) underwent TAVI between 2014 and 2015. Kaplan-Meier event estimates were used to determine mortality by sex. Predictors of overall mortality were identified using a cox multivariate proportional hazard model. RESULTS: At 4 years, women had lower all-cause mortality than men (36.0 vs 39.7%; p = .0911; HR: 0.87 [95% CI: 0.75-1.02]). No difference was observed for cardiac mortality between women 24.2% and men 24.7% (p = .76; HR: 0.97 [95% CI: 0.79-1.19]). When adjusted for baseline characteristics (age, height, weight, NYHA functional class, renal insufficiency, EuroScore, and tricuspid regurgitation), sex had no impact on mortality. CONCLUSIONS: In this large, real-world cohort, all-cause mortality trended lower in women than men at 4 years post TAVI; however, several baseline factors, but not sex, were predictors of mortality. No difference between sexes was observed for cardiovascular mortality.

AIMS: Sacubitril/valsartan has shown efficacy and tolerability in patients with heart failure (HF) and reduced ejection fraction (HFrEF) in the ambulatory setting (PARADIGM-HF), and following stabilisation of acutely decompensated HF (ADHF) (PIONEER-HF and TRANSITION). However, data are lacking for the initiation of sacubitril/valsartan in newly diagnosed (de novo) HFrEF. Here, we assess the tolerability of initiating sacubitril/valsartan following ADHF in TRANSITION subgroups of patients with a de novo vs. prior diagnosis of HFrEF. METHODS AND RESULTS: TRANSITION randomised 1002 patients to pre- and post-discharge initiation of sacubitril/valsartan (analysis set n = 991, following exclusions for mis-randomisation). In this post-hoc analysis, tolerability to sacubitril/valsartan [proportion of patients achieving target dose (97/103 mg b.i.d.) at 10 weeks post-randomisation], adverse events (AEs) and serious AEs (SAEs) were compared in de novo (n = 286) and prior HFrEF (n = 705) subgroups. More de novo than prior HFrEF patients achieved target dose at Week 10 (56% vs. 45%; relative risk ratio 1.30, 95% confidence interval 1.12-1.52, P < 0.001), and fewer had SAEs and permanent treatment discontinuations. Initiation of sacubitril/valsartan did not prevent the concomitant initiation and up-titration of guideline-directed HF therapies. De novo patients showed faster and greater decreases in N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin-T, and lower rates of HF and all-cause rehospitalisation vs. prior HFrEF. CONCLUSIONS: After ADHF, first-line initiation of sacubitril/valsartan in de novo HFrEF, alongside the initiation of other guideline-directed therapies, is feasible and is associated with a better risk-benefit profile than in patients with prior HFrEF. Early intervention with sacubitril/valsartan may be considered to delay disease progression in patients with de novo HFrEF. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT02661217.

AIMS: To assess tolerability and optimal time point for initiation of sacubitril/valsartan in patients stabilised after acute heart failure (AHF). METHODS AND RESULTS: TRANSITION was a randomised, multicentre, open-label study comparing two treatment initiation modalities of sacubitril/valsartan. Patients aged ≥ 18 years, hospitalised for AHF were stratified according to pre-admission use of renin-angiotensin-aldosterone system inhibitors and randomised (n = 1002) after stabilisation to initiate sacubitril/valsartan either ≥ 12-h pre-discharge or between Days 1-14 post-discharge. Starting dose (as per label) was 24/26 mg or 49/51 mg bid with up- or down-titration based on tolerability. The primary endpoint was the proportion of patients attaining 97/103 mg bid target dose after 10 weeks. Median time of first dose of sacubitril/valsartan from the day of discharge was Day -1 and Day +1 in the pre-discharge group and the post-discharge group, respectively. Comparable proportions of patients in the pre- and post-discharge initiation groups met the primary endpoint [45.4% vs. 50.7%; risk ratio (RR) 0.90; 95% confidence interval (CI) 0.79-1.02]. The proportion of patients who achieved and maintained for ≥ 2 weeks leading to Week 10, either 49/51 or 97/103 mg bid was 62.1% vs. 68.5% (RR 0.91; 95% CI 0.83-0.99); or any dose was 86.0% vs. 89.6% (RR 0.96; 95% CI 0.92-1.01). Discontinuation due to adverse events occurred in 7.3% vs. 4.9% of patients (RR 1.49; 95% CI 0.90-2.46). CONCLUSIONS: Initiation of sacubitril/valsartan in a wide range of heart failure with reduced ejection fraction patients stabilised after an AHF event, either in hospital or shortly after discharge, is feasible with about half of the patients achieving target dose within 10 weeks.
