Several heart failure (HF) web-based risk scores are currently used in clinical practice. Currently, we lack head-to-head comparison of the accuracy of risk scores. This study aimed to assess correlation and mortality prediction performance of Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC-HF) risk score, which includes clinical variables + medications; Seattle Heart Failure Model (SHFM), which includes clinical variables + treatments + analytes; PARADIGM Risk of Events and Death in the Contemporary Treatment of Heart Failure (PREDICT-HF) and Barcelona Bio-Heart Failure (BCN-Bio-HF) risk calculator, which also include biomarkers, like N-terminal pro B-type natriuretic peptide (NT-proBNP).
Aims The criteria for patients with heart failure (HF) and improved ejection fraction (HFimpEF) are a baseline left ventricular ejection fraction (LVEF) ≤40%, a ≥10‐point increase from baseline LVEF, and a second LVEF measurement >40%. We aimed to (i) assess patients with HF and reduced LVEF (HFrEF) at baseline and compare quality of life (QoL) changes between those that fulfilled and those that did not fulfil the HFimpEF criteria 1 year later and (ii) assess the prognostic role of QoL in patients with HFimpEF. Methods We reviewed data from a prospective registry of real‐world outpatients with HF that were assessed for LVEF and QoL at a first visit to the HF clinic and 1 year later. QoL was evaluated with the Minnesota Living with Heart Failure Questionnaire (MLWHFQ). The primary prognostic endpoint was the composite of all‐cause death or HF hospitalization. Results Baseline and 1‐year LVEF and MLWFQ scores were available for 1040 patients with an initial LVEF ≤40% (mean age, 65.2 ± 11.7 years; 75.9% men). The main aetiology was ischaemic heart disease (52.9%), and patients were mostly in New York heart Association Classes II (71.1%) and III (21.6%). At baseline, the mean LVEF was 28.5% ± 7.3, and the mean MLWHFQ score was 30.2 ± 19.5. After 1 year, the mean LVEF increased to 38.0% ± 12.2, and the MLWHFQ scores improved to 17.4 ± 16.0. In 361 patients that fulfilled the HFimpEF criteria (34.7%), significant improvements were observed in both LVEF (from 28.7% ± 6.6 to 50.9% ± 7.6, P < 0.001) and QoL (from 32.9 ± 20.6 to 16.9 ± 16.0, P < 0.001). Patients that did not fulfil the HFimpEF criteria also showed significant improvements in LVEF (from 28.4% ± 7.6 to 31.1% ± 7.9, P < 0.001) and QoL (from 28.7 ± 18.8 to 17.6 ± 15.9, P < 0.001). However, the QoL improvement was significantly higher in the HFimpEF group (−16.0 ± 23.8 vs. −11.1 ± 20.3, P = 0.001), despite the worse mean baseline MLWHFQ score, compared with the non‐HFimpEF group (P = 0.001). The 1‐year QoL was similar between groups (P = 0.50). The 1‐year MLWHFQ score was independently associated with outcomes; the hazard ratio for the composite endpoint was 1.02 (95% CI: 1.01–1.03, P = 0.006). In contrast, the QoL improvement (with a cut‐off ≥5 points) was not independently associated with the composite outcome. Conclusions Patients with HFrEF showed improved QoL after 1 year, regardless of whether they met the HFimpEF criteria. The similar 1‐year QoL perception between groups suggested that factors other than LVEF influenced QoL perception. The 1‐year QoL was superior to the QoL change from baseline for predicting prognosis in patients with HFimpEF.
ObjectivesHeart failure (HF) management has significantly improved over the past two decades, leading to better survival. This study aimed to assess changes in predicted mortality risk after 12 months of management in a multidisciplinary HF clinic.Materials and MethodsOut of 1,032 consecutive HF outpatients admitted from March-2012 to November-2018, 357 completed the 12-months follow-up and had N-terminal pro-B-type natriuretic peptide (NTproBNP), high sensitivity troponin T (hs-TnT), and interleukin-1 receptor-like-1 (known as ST2) measurements available both at baseline and follow-up. Three contemporary risk scores were used: MAGGIC-HF, Seattle HF Model (SHFM), and the Barcelona Bio-HF (BCN Bio-HF) calculator, which incorporates the three above mentioned biomarkers. The predicted risk of all-cause death at 1 and 3 years was calculated at baseline and re-evaluated after 12 months.ResultsA significant decline in predicted 1-and 3-year mortality risk was observed at 12 months: MAGGIC ~16%, SHFM ~22% and BCN Bio-HF ~15%. In the HF with reduced ejection fraction (HFrEF) subgroup guideline-directed medical therapy led to a complete normalization of left ventricular ejection fraction (≥50%) in almost a third of the patients and to a partial normalization (41–49%) in 30% of them. Repeated risk assessment after 12 months with SHFM and BCN Bio-HF provided adequate discrimination for all-cause 3-year mortality (C-Index: MAGGIC-HF 0.762, SHFM 0.781 and BCN Bio-HF 0.791).ConclusionMortality risk declines in patients with HF managed for 12 months in a multidisciplinary HF clinic. Repeating the mortality risk assessment after optimizing the HF treatment is recommended, particularly in the HFrEF subgroup.
ObjectiveTo evaluate the incidence, predictive factors and prognostic value of new-onset persistent left bundle branch block (NOP-LBBB) in patients undergoing sutureless surgical aortic valve replacement (SU-SAVR).MethodsA total of 329 consecutive patients without baseline conduction disturbances or previous permanent pacemaker implantation (PPI) who underwent SU-SAVR with the Perceval valve (LivaNova Group, Saluggia, Italy) in two centres from 2013 to 2019 were included. Patients were on continuous ECG monitoring during hospitalisation and 12-lead ECG was performed after the procedure and at hospital discharge. NOP-LBBB was defined as a new postprocedural LBBB that persisted at hospital discharge. Baseline, procedural and follow-up clinical and echocardiography data were collected in a dedicated database.ResultsNew-onset LBBB was observed in 115 (34.9%) patients, and in 76 (23.1%) persisted at hospital discharge. There were no differences in baseline and procedural characteristics between patients with (n=76) and without (n=253) NOP-LBBB. After a median follow-up of 3.3 years (2.3–4.4 years), patients with NOP-LBBB had a higher incidence of PPI (14.5% vs 6.3%, p=0.016), but exhibited similar rates of all-cause mortality (19.4% vs 19.2%, p=0.428), cardiac mortality (8.1% vs 9.4%, p=0.805) and heart failure readmission (21.0% vs 23.2%, p=0.648), compared with the no/transient LBBB group. NOP-LBBB was associated with a decrease in left ventricular ejection fraction (LVEF) at 1-year follow-up (delta: −5.7 vs +0.2, p<0.001).ConclusionsNOP-LBBB occurred in approximately a quarter of patients without prior conduction disturbances who underwent SU-SAVR and was associated with a threefold increased risk of PPI along with a negative impact on LVEF at follow-up.
