    Aims The safety of digoxin therapy in atrial fibrillation (AF) remains ill-defined. We aimed to evaluate the effects of digoxin over beta-blocker therapy in AF. Methods and results Patients with AF who were treated with either digoxin or a beta blocker from the ESC–EHRA EORP AF (European Society of Cardiology–European Heart Rhythm Association EURObservational Research Programme Atrial Fibrillation) General Long-Term Registry were included. Outcomes of interest were all-cause mortality, cardiovascular (CV) mortality, non-CV mortality, quality of life, and number of patients with unplanned hospitalizations. Of 6377 patients, 549 (8.6%) were treated with digoxin. Over 24 months, there were 550 (8.6%) all-cause mortality events and 1304 (23.6%) patients with unplanned emergency hospitalizations. Compared to beta blocker, digoxin therapy was associated with increased all-cause mortality [hazard ratio (HR) 1.90 (95% confidence interval, CI, 1.48–2.44)], CV mortality [HR 2.18 (95% CI 1.47–3.21)], and non-CV mortality [HR 1.68 (95% CI 1.02–2.75)] with reduced quality of life [health utility score 0.555 (±0.406) vs. 0.705 (±0.346), P < 0.001] but no differences in emergency hospitalizations [HR 1.00 (95% CI 0.56–1.80)] or AF-related hospitalizations [HR 0.95 (95% CI 0.60–1.52)]. On multivariable analysis, there were no differences in any of the outcomes between both groups, after accounting for potential confounders. Similar results were obtained in the subgroups of patients with permanent AF and coexisting heart failure. There were no differences in outcomes between AF patients receiving digoxin with and without chronic kidney disease. Conclusion Poor outcomes related to the use of digoxin over beta-blocker therapy in terms of excess mortality and reduced quality of life are associated with the presence of other risk factors rather than digoxin per se. The choice of digoxin or beta-blocker therapy had no influence on the incidence of unplanned hospitalizations.

    Background The objectives of this study were to evaluate the incidence of no-reflow as independent predictor of adverse events and to assess whether baseline pre-procedural treatment options may affect clinical outcomes. Methods Data were derived from the ISACS-TC registry (NCT01218776) from October 2010 to January 2015. No-reflow was defined as post-PCI TIMI flow grades 0–1, in the absence of post-procedural significant (≥25%) residual stenosis, abrupt vessel closure, dissection, perforation, thrombus of the original target lesion, or epicardial spasm. The outcome measure was in-hospital mortality. Results No-reflow was identified in 128 of 5997 patients who have undergone PCI (2.1%). On multivariate analysis, patients with no-reflow were more likely to be older (OR: 1.20, 95% CI: 1.01–1.44), to have a history of hypercholesterolemia (OR: 1.95, 95% CI: 1.31–2.91) and to be admitted with a diagnosis of STEMI (OR: 2.96, 95% CI: 1.85–4.72). Angiographic characteristics associated with no-reflow phenomenon were: stenosis ≥50% of the right coronary artery, presence of multivessel disease and pre-procedural TIMI blood flow grades 0–1. No-reflow was highly predictive of in-hospital mortality (17.2% vs. 4.2%; adjusted OR: 4.60, 95% CI: 2.61–8.09). Administration of pre-procedural unfractioned heparin or 600mg clopidogrel loading dose was associated with less incidence of no-reflow (OR: 0.65, 95% CI: 0.43–0.99 and 0.61, 95% CI: 0.37–1.00, respectively). Aspirin, enoxaparin, and 300mg clopidogrel loading dose, did not significantly impact the occurrence of the no-reflow. Conclusions We found that pre-procedural administration of 600mg loading dose of clopidogrel and/or unfractioned heparin is associated with reduced incidence of no-reflow.

    Objective: To address the association between psychiatric disorders and short-term outcomes after acute symptomatic pulmonary embolism (PE). Methods: We identified adults with PE enrolled in the RIETE registry between December 1, 2013, and January 31, 2019. Using multinomial regression, we assessed the association between a history of psychiatric disorders and the outcomes of all-cause mortality, PE-related mortality, and venous thromboembolism recurrence and bleeding rates through 30 days after initiation of treatment. We also examined the impact of depression on all-cause and PE-specific mortality. Results: Among 13,120 patients diagnosed with acute PE, 16.1% (2115) had psychiatric disorders and 4.2% died within the first 30-days of follow-up. Patients with psychiatric disorders had increased odds for all-cause (adjusted odds ratio [OR] 1.50; 95% CI, 1.21 to 1.86; P < 0.001) and PE-related mortality (adjusted OR 1.64; 95% CI, 1.09 to 2.48; P = 0.02) compared to those without psychiatric disorders. Multinomial logistic regression showed a non-significant trend toward lower risk of recurrences for patients with psychiatric disorders (adjusted OR 0.49; 95% CI, 0.21 to 1.15; P = 0.10). Psychiatric disorders were not significantly associated with increased odds for major bleeds during follow-up (adjusted OR 1.09; 95% CI, 0.85 to 1.40; P = 0.49). Results were consistent in a sensitivity analysis that only considered patients with a diagnosis of depression. Conclusions: In patients with acute PE, history of psychiatric disorders might predict all-cause and PE-related death in the ensuing month after diagnosis.

    The association between inferior vena cava filter (IVC) use and outcome in patients presenting with major bleeding during anticoagulation for venous thromboembolism (VTE) has not been thoroughly investigated. We used the RIETE registry to compare the 30-day outcomes (death, major re-bleeding or VTE recurrences) in VTE patients who bled during the first 3 months of therapy, regarding the insertion of an IVC filter. A propensity score matched (PSM) analysis was performed to adjust for potential confounders. From January 2001 to September 2016, 1065 VTE patients had major bleeding during the first 3 months of anticoagulation (gastrointestinal 370; intracranial 124). Of these, 122 patients (11%) received an IVC filter. Patients receiving a filter restarted anticoagulation later (median, 4 vs. 2 days) and at lower doses (95 ± 52 IU/kg/day vs. 104 ± 55 of low-molecular-weight heparin) than those not receiving a filter. During the first 30 days after bleeding (after excluding 246 patients who died within the first 24 h), 283 patients (27%) died, 63 (5.9%) had non-fatal re-bleeding and 19 (1.8%) had recurrent pulmonary embolism (PE). In PSM analysis, patients receiving an IVC filter (n = 122) had a lower risk for all-cause death (HR 0.49; 95% CI 0.31-0.77) or fatal bleeding (HR 0.16; 95% CI 0.07-0.49) and a similar risk for re-bleeding (HR 0.55; 95% CI 0.23-1.40) or PE recurrences (HR 1.57; 95% CI 0.38-6.36) than those not receiving a filter (n = 429). In VTE patients experiencing major bleeding during the first 3 months, use of an IVC filter was associated with reduced mortality rates.Clinical Trial Registration NCT02832245.
