RESUMO
BACKGROUND AND AIMS: Nutritional status (NS) is not routinely assessed in HF. We sought to evaluate whether NS may be additive to a comprehensive pre-discharge evaluation based on a clinical score that includes BMI (MAGGIC) and on an index of functional capacity (six minute walking test, 6mWT) in HF patients. METHODS AND RESULTS: The CONUT (Controlling Nutritional Status) score (including serum albumin level, total cholesterol and lymphocyte count) was computed in 466 consecutive patients (mean age 61 ± 11 years, NYHA class 2.6 ± 0.6, LVEF 34 ± 11%, BMI 27.2 ± 4.5) who had pre-discharge MAGGIC and 6MWT. The endpoint was all-cause mortality. Mild or moderate undernourishment was present in 54% of patients with no differences across BMI strata. The 12-month event rate was 7.7%. Deceased patients had a more compromised NS (CONUT 2.8 ± 1.5 vs 1.7 ± 1.3, p < 0.0001), and a more advanced HF (MAGGIC 28.2 ± 6.0 vs 22.0 ± 6.6, p < 0.0001; 6MWT 311.1 ± 102.2 vs. 408.9 ± 95.9 m, p < 0.0001). The 12-month mortality rate varied from 4% for well-nourished to 11% for undernourished patients (p = 0.008). At univariate analysis, the CONUT was predictive for all-cause mortality with a Hazard Ratio of 1.701 [95% CI 1.363-2.122], p < 0.0001. Multivariable analysis showed that the CONUT significantly added to the combination of MAGGIC and 6MWT and improved predictive discrimination and risk classification (c-index 0.82 [95% CI 0.75-0.88], integrated discrimination improvement 0.028 [95% CI 0.015-0.081]). CONCLUSIONS: In HF patients assessment of NS, significantly improves prediction of 12-month mortality on top of the information provided by clinical evaluation and functional capacity and should be incorporated in the overall assessment of HF patients.

OBJECTIVES: Acute pulmonary embolism (PE) is a potentially life-threatening condition characterized by the sudden blockage of the pulmonary arteries. Although the MAGGIC risk score has emerged as a valuable tool in predicting outcomes in patients with chronic heart failure, it has also been demonstrated and identified as a prognostic model in various cardiac diseases other than heart failure. In this study, we aimed to investigate the relationship between MAGGIC score and adverse outcomes in patients with PE. MATERIALS AND METHODS: A total of 302 consecutive patients diagnosed with acute PE were retrospectively included in the present study. For each patient, the MAGGIC score was calculated. The study population was divided into two groups according to the median value of MAGGIC score. RESULTS: Patients with high MAGGIC score had a significantly higher proportion of elderly and female individuals, lower BMI, higher presence of CAD, DM, AFib, HF, HT, CKD, COPD, and ACEI/ARB and NOAC usage. Logistic regression analyses was carried out using univariate and multivariate analysis to predict the in-hospital and 30-day mortality predictors in the included PE patients. For in-hospital mortality, diastolic blood pressure, heart rate, RV dilatation, and the MAGGIC score (HR: 1.166, 95% CI 1.077-1.263, p < 0.001) and for short-term mortality, sPESI and the MAGGIC score (HR: 1.925, 95% CI 1.243-2.983, p:0.003) were found to be independent predictors for adverse outcomes in patients with acute PE. CONCLUSION: Our study demonstrates that the MAGGIC score can be applied as a valuable prognostic tool for acute pulmonary embolism.
RESUMO
Background: The obesity occurrence has achieved epidemic levels worldwide and several studies indicate a paradoxical similarity among obesity and the prognosis in heart failure (HF). The primary objective was to understand the association between body mass index (BMI) and heart failure with reduced ejection fraction (HFREF) of ischemic etiology in outpatients, using mortality as a parameter. The secondary objectives were to determine the differences in HF functional class, pharmacological therapy and evaluate the prognostic value of MAGGIC Score in this population. Methods: We analyzed 1,556 medical records from the HF outpatient clinic of a quaternary hospital and 242 were selected according to the criteria. Most were male, average age 62.6 (56-70), BMI 18.5-24.9 = 35.1%, 25-29.9 = 37.2%, 30-34.9 = 17.8%, 35-39.9 = 7%; BMI <18.5 and >40 groups were eliminated from the central analyzes because of scarce testing. Results: BMI 30-34.9 and BMI 18.5-24.9 had the best prognosis, BMI 25-29.9 had an average performance, and BMI -39.9 group provided the worst outcome (p = 0.123). In the subcategory analysis, BMI 30-34.9 group had a better prognosis compared to the BMI 35-39.9 group (p = 0.033). In the multivariate analysis The MAGGIC score was not able to foretell mortality in this population according to BMI. Conclusion: In not hospitalized patients with HFREF of ischemic etiology, obesity was not a protective factor.
RESUMO
Background The angiotensin receptor-neprilysin inhibitor (LCZ696) has emerged as a promising pharmacological intervention against renin-angiotensin system inhibitor in reduced ejection fraction heart failure (HFrEF). Whether the therapeutic benefits may vary among heterogeneous HFrEF subgroups remains unknown. Methods and Results This study comprised a pooled 2-center analysis including 1103 patients with symptomatic HFrEF with LCZ696 use and another 1103 independent HFrEF control cohort (with renin-angiotensin system inhibitor use) matched for age, sex, left ventricular ejection fraction, and comorbidity conditions. Three main distinct phenogroup clusterings were identified from unsupervised machine learning using 29 clinical variables: phenogroup 1 (youngest, relatively lower diabetes prevalence, highest glomerular filtration rate with largest left ventricular size and left ventricular wall stress); phenogroup 2 (oldest, lean, highest diabetes and vascular diseases prevalence, lowest highest glomerular filtration rate with smallest left ventricular size and mass), and phenogroup 3 (lowest clinical comorbidity with largest left ventricular mass and highest hypertrophy prevalence). During the median 1.74-year follow-up, phenogroup assignment provided improved prognostic discrimination beyond Meta-Analysis Global Group in Chronic Heart Failure risk score risk score (all net reclassification index P<0.05) with overall good calibrations. While phenogroup 1 showed overall best clinical outcomes, phenogroup 2 demonstrated highest cardiovascular death and worst renal end point, with phenogroup 3 having the highest all-cause death rate and HF hospitalization among groups, respectively. These findings were broadly consistent when compared with the renin-angiotensin system inhibitor control as reference group. Conclusions Phenomapping provided novel insights on unique characteristics and cardiac features among patients with HFrEF with sacubitril/valsartan treatment. These findings further showed potentiality in identifying potential sacubitril/valsartan responders and nonresponders with improved outcome discrimination among patients with HFrEF beyond clinical scoring.

Background: Left ventricular (LV) systolic strain is presumably a more sensitive myocardial indicator than LV ejection fraction (LVEF). Data regarding the use of LV strain in clinical risk stratification and in identifying angiotensin receptor-neprilysin inhibitor (ARNi) responders remain scarce in heart failure with mildly reduced ejection fraction (HFmrEF). Objectives: The authors aimed to examine whether assessing LV strain may provide prognostic insight beyond LVEF and help discriminate the therapeutic efficacy of ARNi in HFmrEF patients. Methods: LVEF and LV strain were quantified among 1,075 first-time hospitalized HFmrEF patients (mean age: 68.1 ± 15.1 years, 40% female). The MAGGIC (Meta-analysis Global Group in Chronic Heart Failure) risk score and its components were calculated. A Cox proportional hazard model was constructed for time-to-event analysis. Restrictive cubic spline curves were used to model the therapeutic effects of ARNi against renin-angiotensin system inhibitor according to baseline LVEF or LV strain. Results: LV strain showed a statistically significant inverse association with MAGGIC cardiac risk (coefficient: -0.14, P < 0.001). LV strain was independently associated with clinical outcomes after accounting for LVEF. MAGGIC-LV strain strata outperformed MAGGIC-LVEF strata in overall survival (Harrell's C-index: 0.71 and 0.56, P for difference <0.001; category-free net reclassification index: 0.44, P < 0.001). Lower LV strain but not LVEF consistently showed the beneficial therapeutic effects of ARNi against renin-angiotensin system inhibitor by Cox models and restrictive cubic spline (all P interaction <0.05). Conclusions: Among HFmrEF patients, LV strain may serve as an attractive systolic marker and provide a better prognostic and therapeutic discriminative measure for ARNi treatment than conventional LVEF.
RESUMO
Heart failure (HF) is a chronic progressive disease with high morbimortality and poor quality of life (QoL). Palliative care significantly improves clinical outcomes but few patients receive it, in part due to challenging decisions about prognosis. This retrospective study, included all patients consecutively discharged from an Acute Heart Failure Unit over a period of one year, aiming to assess the accuracy of the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score in predicting mortality. Additionally, predictors of death at one and three years were explored using a multivariate regression model. The MAGGIC score was useful in predicting mortality, without significant difference between mortality observed at three-years follow-up compared with a mortality given by the score (p=0.115). Selected variables were statistically compared showing that poor functional status, high New York Heart Association (NYHA) at discharge, psychopharmacs use, and high creatininemia were associated with higher mortality (p<0.05). The multivariate regression model identified three predictors of one-year mortality: psychopharmacs baseline use (OR=4.110; p=0.014), angiotensin-converting enzyme inhibitors/angiotensin receptor blocker (ACEI/ARB) medication at discharge (OR=0.297; p=0.033), and higher admission's creatinine (OR=2.473; p=0.028). For three-year mortality outcome, two variables were strong independent predictors: psychopharmacs (OR=3.330; p=0.022) and medication with ACEI/ARB at discharge (OR=0.285; p=0.018). Models' adjustment was assessed through the receiver operating characteristic (ROC) curve. The best model was the one-year mortality (area under the curve, AUC 81%), corresponding to a good discrimination power. Despite prognostication, when setting goals of care an individualised patient-centred approach is imperative, based on the patient's objectives and needs. Risk factors related to poorer outcomes should be considered, in particular, higher NYHA at discharge which also represents symptom burden. Hospitalisation is an opportunity to optimize global care for heart failure patients including palliative care.
RESUMO
PURPOSE: Catheter ablation (CA) for atrial fibrillation (AF) in heart failure (HF) patients is associated with a lower rate of cardiac events compared with medical therapy. This study deals with the clinical, echocardiographic, and prognostic outcomes in these patients. Prognostic scores, as MAGGIC (Meta-analysis Global Group in Chronic Heart Failure) score, may help to predict the outcomes. METHODS: From a single center, 47 patients with AF, HF, and left ventricular ejection fraction (LVEF) < 50% underwent CA. The primary endpoints were NYHA functional class, LVEF, and MAGGIC score. RESULTS: The median age of patients was 59 years; 49% had paroxysmal AF. At 12 months, a significant improvement of NYHA class (median before II [interquartile range (IQR) II-III] vs median after I [IQR I-II]) and of LVEF (median before 44% [IQR 37-47] vs median after 55% [IQR49-57]) was observed (p value < 0.001). The MAGGIC 1-year and 3-year probability of death was estimated before (mean score 13 [IQR 11-17]) and at 12-month (mean score 11 [IQR 8-13]), showing a significant decrease in the probability of death (p value <0.001). At 12-month, a lower LVEF was associated with more HF hospitalizations (p value 0.035). Coronary artery disease (CAD) (HR 5, p value 0.035) and MAGGIC score (HR 1.2, p value 0.030) were predictors of HF hospitalization. CONCLUSIONS: CA for AF in HF patients was associated with a significant improvement of NYHA functional class and LVEF and a higher life expectation. CAD history, LVEF < 40%, and MAGGIC score before ablation were predictors of HF hospitalization.

BACKGROUND: MitraClip ® (MC) is an established procedure for severe mitral regurgitation (MR) in patients deemed unsuitable for surgery.Right ventricular dysfunction (RVD) is associated with a higher mortality risk. The prognostic accuracy of heart failure risk scores like the Seattle heart failure model (SHFM) and Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score in pts undergoing MC with or without RVD has not been investigated so far. METHODS: SHFM and MAGGIC score were calculated retrospectively. RVD was determined as tricuspid annular plane systolic excursion (TAPSE) ≤15 mm. Area under receiver operating curves (AUROC) of SHFM and MAGGIC were performed for one-year all-cause mortality after MC. RESULTS: N = 103 pts with MR III° (73 ± 11 years, LVEF 37 ± 17%) underwent MC with a reduction of at least I° MR. One-year mortality was 28.2%.In Kaplan-Meier analysis, one- year mortality was significantly higher in RVD-pts (34.8% vs 2.8%, p = 0.009).Area under the Receiver Operating Characteristic (AUROC) for SHFM and MAGGIC were comparable for both scores (SHFM: 0.704, MAGGIC: 0.692). In pts without RVD, SHFM displayed a higher AUROC and therefore better diagnostic accuracy (SHFM: 0.776; MAGGIC: 0.551, p < 0.05). In pts with RVD, MAGGIC and SHFM displayed comparable AUROCs. CONCLUSION: RVD is an important prognostic marker in pts undergoing MC. SHFM and MAGGIC displayed adequate over-all prognostic power in these pts. Accuracy differed in pts with and without RVD, indicating higher predictive power of the SHFM score in pts without RVD.
RESUMO
AIMS: The poor control of symptoms in patients with advanced heart failure with reduced ejection function (HFrEF) can limit the functionality of patients. Sacubitril-valsartan, compared with enalapril, has been shown to reduce mortality and hospitalization, and nowadays, there is still little evidence about the improvement on functionality. The aim of our study is to analyse the improvement of the functional class and the 6 min walking test (6MWT) in patients with multiple pathologies and advanced heart failure. METHODS AND RESULTS: From September 2016 to March 2018, 65 multimorbidity patients with severe symptomatic HFrEF were initiated to receive sacubitril-valsartan. Mean age was 78.6 ± 7.4 years, and 68% were male. The Charlson co-morbidity index was 8 points. Seventy-four per cent had New York Heart Association (NYHA) Functional Class IV. After the treatment, patients were able to achieve 55.68 m or more on 6MWT, and 91% presented an improvement in the NYHA functional class. CONCLUSIONS: Sacubitril-valsartan relieves symptoms and improves functional class prognostic risk of patients with advanced HFrEF and co-morbidity.
