The impact of implantable cardioverter-defibrillator implantation on health-related quality of life in the DANISH trial.

AIM: The Danish Study to Assess the Efficacy of Implantable Cardioverter-Defibrillators (ICD) in Patients with Non-ischaemic Systolic Heart Failure (HF) on Mortality (DANISH) found no overall effect on all-cause mortality. The effect of ICD implantation on health-related quality of life (HRQoL) remains to be established as previous trials have demonstrated conflicting results. We investigated the impact of ICD implantation on HRQoL in patients with non-ischaemic systolic HF, a prespecified secondary endpoint in DANISH. METHODS AND RESULTS: In DANISH, a total of 1116 patients with non-ischaemic systolic HF were randomly assigned (1:1) to ICD implantation or usual clinical care (control). Patients completed disease-specific HRQoL as assessed by Minnesota Living with Heart Failure Questionnaire (MLHFQ; 0-105, high indicating worse). Changes in HRQoL 8 months after randomization were assessed with a mixed-effects model. At randomization, MLHFQ was completed by 935 (84%) patients (n = 472 in the ICD group and n = 463 in the control group) and was reassessed in 274 (58%) and 292 (63%) patients, respectively after 8 months for the primary analysis. Patients in the ICD group vs. the control group had similar improvements in MLHFQ after 8 months [least square mean -7.0 vs. -4.2 (P = 0.13)]. A clinically relevant improvement (decrease ≥5) in the MLHFQ overall score at 8 months was observed in 151 patients in the ICD group and 148 patients in the control group [55% vs. 51%, respectively (P = 0.25)]. CONCLUSION: Implantable cardioverter-defibrillator implantation in patients with non-ischaemic systolic HF did not significantly alter HRQoL compared with patients randomized to usual clinical care.

Drug survival of biologics and novel immunomodulators for rheumatoid arthritis, axial spondyloarthritis, psoriatic arthritis, and psoriasis - A nationwide cohort study from the DANBIO and DERMBIO registries.

OBJECTIVE: Drug survival is an important proxy measure for effectiveness of treatments for inflammatory diseases such as rheumatoid arthritis (RA), axial spondyloarthritis (AxSpA), psoriatic arthritis (PsA), and psoriasis. The objective of this study was to examine the real-life drug survival of biologics and novel small-molecule therapies across various disease entities such as RA, AxSpA, PsA, and psoriasis. METHODS: We performed a nationwide cohort study using the prospective nationwide registries DANBIO and DERMBIO, comprising all patients treated with biologics or novel small-molecule therapies for RA, AxSpA, PsA, and psoriasis between January 2015 through May 2021 (DANBIO) and November 2009 to November 2019 (DERMBIO). Drug survival was visualized using Kaplan-Meier curves, and Cox proportional hazards models were used to calculate adjusted Hazard Ratios (HRs) with 95% confidence intervals (CIs) for risk of discontinuing therapy. FINDINGS: The study comprised a total of 12,089 patients (17,903 treatment series), including 5,104 RA patients (7,867 series), 2,157 AxSpA patients (3,016 series3), 2,551 PsA patients (3,313 series), and 2,577 psoriasis patients (3,707 series). In confounder-adjusted models drug survival in RA was highest for rituximab followed by baricitinib, etanercept and tocilizumab respectively. For AxSpA, drug survival was high for golimumab compared to all other drugs, followed by secukinumab and etanercept and lowest for infliximab. For PsA, tofacitinib and infliximab had the lowest drug survival compared to all other drugs. All other drugs performed almost equally well with a tendency of a somewhat higher drug survival for golimumab, followed by secukinumab and ixekizumab. For psoriasis, drug survival was generally highest for guselkumab. INTERPRETATION: Differing treatment responses to drugs with various modes of action across RA, AxSpA, PsA and psoriasis emphasize that although these diseases have many overlaps in their pathogenesis, there is a need for an individualized treatment approach that considers the underlying disease, patient profile, and treatment history. FUNDING: None.

Quality of life and the associated risk of all-cause mortality in nonischemic heart failure.

OBJECTIVES: To examine the association between health-related quality of life (HRQoL) and mortality in patients with heart failure (HF). BACKGROUND: The potential association of HRQoL and mortality in patients with HF is unclear. We investigated this association in The Danish Study to Assess the Efficacy of Implantable Cardioverter Defibrillators (ICD) in Patients with Non-ischemic Systolic Heart Failure on Mortality (DANISH). METHODS: In DANISH, a total of 1116 patients with non-ischemic systolic HF on guideline-recommended therapy were randomized to ICD therapy or usual clinical care. HRQoL was assessed at randomization using the disease-specific Minnesota Living with Heart Failure Questionnaire (MLHFQ, 0-105, high score indicating worse HRQoL). Multivariable Cox proportional hazard models were used to compare hazard ratios (HR) for all-cause mortality according to MLHFQ above or below 45, as recommended by a recent meta-analysis, to identify patients with poor HRQoL. RESULTS: HRQoL was completed by 935 (84%) patients at baseline with a median follow-up of 67 months (IQR 47-83). Patients with poor HRQoL (MLHFQ score > 45, median 60 (IQR 53-71),n = 350) had a higher incidence of all-cause mortality than patients with moderate/good HRQoL (MLHFQ ≤45, median 23 (IQR 13-33), n = 585), respectively 26% vs. 18% with an unadjusted HR of 1.57 (95% CI 1.19-2.08, p = .002), and an adjusted HR of 1.39 (95% CI 1.01-1.91, p = .04). CONCLUSION: Poor HRQoL was associated with an increased risk of all-cause mortality after adjustment for traditional risk factors.

Long-term Thromboembolic Risk in Patients With Postoperative Atrial Fibrillation After Left-Sided Heart Valve Surgery.

Importance: New-onset postoperative atrial fibrillation (POAF) is a common complication of cardiac surgery. However, data on the long-term risk of thromboembolism in patients who develop POAF after heart valve surgery are conflicting. In addition, data on stroke prophylaxis in this setting are lacking. Objective: To assess the long-term risk of thromboembolism in patients developing new-onset POAF after isolated left-sided heart valve surgery relative to patients with nonsurgical, nonvalvular atrial fibrillation (NVAF). Design, Setting, and Participants: This observational cohort study was conducted from January 1, 2000, through December 31, 2015, using Danish nationwide registries and the Eastern Danish Heart Surgery Database. Patients who developed POAF after isolated left-sided heart valve surgery (bioprosthetic aortic or mitral valve replacement and/or aortic or mitral valve repair) from 2000 through 2015 were included. These patients were matched with patients with nonsurgical NVAF in a 1:3 ratio by age, sex, heart failure, hypertension, diabetes, a history of thromboembolism, ischemic heart disease, and year of diagnosis. Data analyses took place from January to March 2019. Main Outcomes and Measures: Rates of thromboembolism. Results: Of the 1587 patients who underwent isolated left-sided heart valve surgery, 741 patients (46.7%) developed POAF during admission. Of the 712 patients with POAF who were eligible for matching, 675 patients were matched with 2025 patients with NVAF and made up the study population. In the matched study population, the median age was 71 (interquartile range, 65-77) years, and 1600 (59.3%) were men. Oral anticoagulation therapy was initiated within 30 days postdischarge in 420 patients with POAF (62.9%) and in 1030 patients with NVAF (51.4%). The crude incidence rates of thromboembolism were 21.9 (95% CI, 17.4-27.6) and 17.7 (95% CI, 15.2-20.6) events per 1000 person-years for patients with POAF and patients with NVAF, respectively. In the adjusted analysis, the long-term risk of thromboembolism was similar in patients with POAF and NVAF (hazard ratio, 1.22 [95% CI, 0.88-1.68]). Oral anticoagulation therapy during follow-up was associated with a lower risk of thromboembolic events in patients with POAF (hazard ratio, 0.45 [95% CI, 0.22-0.90]) as well as patients with NVAF (hazard ratio, 0.63 [95% CI, 0.45-0.87]) compared with no anticoagulation therapy. Conclusions and Relevance: New-onset POAF after isolated left-sided heart valve surgery was associated with a similar long-term risk of thromboembolism as NVAF. These data warrant studies addressing the role of anticoagulation therapy in POAF after left-sided heart valve surgery.
