Aims: Despite numerous trials on revascularization in patients with heart failure (HF) and ischaemic left ventricular (LV) dysfunction, its role remains unsettled. Guideline-directed medical therapy (GDMT) for HF has shown benefits on outcomes. This multicentre study aims to compare long-term mortality between revascularization and GDMT in patients with ischaemic LV dysfunction following admission for HF.

Methods and results: Between 2012 and 2023, 408 patients admitted for HF with a LV ejection fraction (LVEF) of 40% or less and documented coronary artery disease (CAD) were included. Patients were categorized into two groups based on their initial treatment decision: revascularization (percutaneous coronary intervention [PCI] or coronary artery bypass graft [CABG]) or GDMT. The primary outcome was rate of all-cause or cardiovascular mortality, and secondary outcomes included type of revascularization (PCI vs. CABG) and LV reverse remodelling. After a median 44.6-month follow-up, 100 patients (33%) died in the revascularization group, compared to 44 (43%) in the GDMT group. Multivariate analysis showed no significant benefit of revascularization on all-cause mortality (hazard ratio [HR] 0.81, 95% confidence interval [CI] 0.48-1.39, p = 0.45) or cardiovascular mortality (HR 0.97, 95% CI 0.62-1.52, p = 0.90) compared to GDMT. Neither CABG (HR 0.74, 95% CI 0.51-1.08, p = 0.13) nor PCI (HR 0.98, 95% CI 0.62-1.55, p = 0.93) demonstrated a mortality reduction compared to GDMT. Both groups experienced significant reductions in LV size and improvements in LVEF, greater in the revascularization group.

Conclusion: Revascularization did not outperform GDMT in ischaemic LV dysfunction following HF admission in this retrospective analysis. Larger prospective studies are needed to clarify the potential role of revascularization in improving outcomes.

Aims: In TRED-HF, 40% of patients with recovered dilated cardiomyopathy (DCM) relapsed in the short term after therapy withdrawal. This follow-up investigates the longer-term effects of therapy withdrawal.

Methods and results: TRED-HF was a randomized trial investigating heart failure therapy withdrawal in patients with recovered DCM over 6 months. Those randomized to continue therapy subsequently withdrew treatment between 6 and 12 months. Participants were recommended to restart therapy post-trial and were followed until May 2023. Clinical outcomes are reported in a non-randomized fashion from enrolment and from the end of the trial. The primary outcome was relapse defined as ≥10% reduction in left ventricular ejection fraction to <50%, doubling in N-terminal pro-B-type natriuretic peptide to >400 ng/L, or clinical features of heart failure. From enrolment to the last follow-up (median 6 years, interquartile range 6-7), 33 of 51 patients (65%) relapsed. The 5-year relapse rate from enrolment was 61% (95% confidence interval [CI] 45-73) and from the end of the trial was 39% (95% CI 19-54). Of 20 patients who relapsed during the trial, nine had a recurrent relapse during follow-up. Thirteen relapsed for the first time after the trial; seven had restarted low intensity therapy, four had not restarted therapy and two did not have therapy withdrawn. The mean intensity of therapy was lower after the trial compared to enrolment (mean difference -6 [-8 to -4]; p < 0.001). One third of relapses during follow-up had identifiable triggers (arrhythmia [n = 4], pregnancy [n = 1], hypertension [n = 1], infection [n = 1]). Corrected atrial fibrillation was associated with reduced risk of relapse (hazard ratio 0.33, 95% CI 0.12-0.96; p = 0.042).

Conclusions: The risk of relapse in the 5 years following the TRED-HF trial remained high. Restarting lower doses of heart failure medications at the end of the trial, external triggers and disease progression are likely to have contributed to relapse.

Aims: To investigate whether seasonal influenza and COVID-19 vaccinations influence the severity of decompensations and long-term outcomes of patients with acute heart failure (AHF).

Methods and results: We included consecutive AHF patients attended at 40 Spanish emergency departments during November and December 2022. They were grouped according to whether they had received seasonal influenza and COVID-19 vaccination. The severity of heart failure (HF) decompensation was assessed with the MEESSI scale, need for hospitalization, intensive care unit (ICU) admission, and in-hospital mortality. Long-term outcomes were 90-day and 1-year all-cause mortality. Associations between vaccination, HF decompensation severity, and long-term outcomes were investigated. Subgroup analyses were executed for 16 patient characteristics and their relationship with vaccination and 1-year mortality. We analysed 4243 patients (median age 85 years; interquartile range 77-90; 57% female): 1841 (43%) had received influenza vaccination, 3139 (74%) COVID-19 vaccination, 1773 (41.8%) received both vaccines (full vaccination) and 1036 (24.4%) none. Previous episodes of AHF, chronic obstructive pulmonary disease and chronic treatment with diuretics were associated with vaccination (either influenza, COVID-19 and full vaccination). High or very-high risk decompensation occurred in 18.6%; hospitalization in 72.3%, ICU admission in 1.1%, and in-hospital mortality in 8.4%. Influenza vaccination was associated with lower hospitalization rates (adjusted odds ratio [OR] 0.746, 95% confidence interval [CI] 0.636-0.876) and in-hospital mortality (OR 0.761, 95% CI 0.583-0.992), while COVID-19 vaccination was associated with increased hospitalizations (OR 1.215, 95% CI 1.016-1.454). Overall, 90-day and 1-year mortality were 20.3% and 34.4%. Both were decreased in influenza-vaccinated patients (adjusted hazard ratio [HR] 0.831, 95% CI 0.709-0.973; and HR 0.885, 95% CI 0.785-0.999, respectively) but only at 90 days in COVID-19 vaccinated patients (HR 0.829, 95% CI 0.702-0.980). Full vaccination achieved even greater reductions in in-hospital, 90-day, and 1-year mortality (HR 0.638, 95% CI 0.479-0.851; HR 0.702, 95% CI 0.592-0.833; and HR 0.815, 95% CI 0.713-0.931, respectively). Subgroup analysis based on patient-related characteristics demonstrated the consistence of vaccination with long-term survival.

Conclusion: In HF patients, seasonal influenza vaccination appears to be associated with less severe decompensation and lower 1-year mortality, while no firm conclusions can be drawn from the results of the present study regarding the benefits of COVID-19 vaccination. Full vaccination is associated with the greatest reduction in short- and long-term mortality.
