RESUMO

A higher neprilysin activity has been suggested in women. In this retrospective analysis, we evaluated the association of sex and body mass index (BMI) with soluble neprilysin (sNEP) and recurrent admissions among 1021 consecutive HF outpatients. The primary and secondary endpoints were the number of HF hospitalizations and all-cause mortality, respectively. The association between sNEP with either endpoint was evaluated across sex and BMI categories (≥ 25 kg/m2 vs. < 25 kg/m2). Bivariate count regression (Poisson) was used, and risk estimates were expressed as incidence rates ratio (IRR). During a median follow-up of 6.65 years (percentile 25%-percentile 75%:2.83-10.25), 702 (68.76%) patients died, and 406 (40%) had at least 1 HF hospitalization. Median values of sNEP and BMI were 0.64 ng/mL (0.39-1.22), and 26.9 kg/m2 (24.3-30.4), respectively. Left ventricle ejection fraction was < 40% in 78.9% of patients, and 28% were women. In multivariable analysis, sNEP (main effect) was positively associated with HF hospitalizations (p = 0.001) but not with mortality (p = 0.241). The predictive value of sNEP for HF hospitalizations varied non-linearly across sex and BMI categories (p-value for interaction = 0.003), with significant and positive effect only on women with BMI ≥ 25 kg/m2 (p = 0.039). For instance, compared to men, women with sNEP of 1.22 ng/mL (percentile 75%) showed a significantly increased risk (IRRs: 1.26; 95% CI: 1.05-1.53). The interaction analysis for mortality did not support a differential prognostic effect for sNEP (p = 0.072). In conclusion, higher sNEP levels in overweight women better predicted an increased risk of HF hospitalization.

RESUMO

In patients with heart failure (HF), the exhaled concentrations of hydrogen after a breath test-a non-invasive assessment of small intestinal overgrowth- has been related to HF severity and higher risk of adverse outcomes. Indeed, two intestinal bacterial metabolites-blood Trimethylamine N-Oxide (TMAO) and butyrate-have been related to a worse prognosis in HF. However, the relationship between the exhaled concentrations of hydrogen after a breath test and these two metabolites remains unknown. Thus, in this post-hoc analysis, we sought to evaluate whether these two metabolites are associated with the exhaled concentrations of hydrogen after a breath test in patients with a recent admission for HF. We included 60 patients with a recent hospitalization for HF. Cumulative hydrogen over time was integrated into a single measurement by the area under the concentration curve (AUC-H2). A linear regression multivariable analysis was used to evaluate the associations. A 2-sided p-value < 0.05 was considered to be statistically significant. The median (p25-p75) amino-terminal pro-brain natriuretic peptide, AUC-H2, TMAO, and Butyrate were 4789 pg/ml (1956-11149), 1615 (700-2585), 0.68 (0.42-1.12), and 0.22 ± 13, respectively. After multivariate adjustment, TMAO and butyrate were significantly associated with AUC-H2 (p = 0.027 and p = 0.009, respectively). For TMAO, this association was positive and for butyrate, negative. Bacterial-origin metabolites TMAO and Butyrate were independently related to AUC-H2 in patients with a recent hospitalization for acute HF.

RESUMO

INTRODUCTION AND OBJECTIVES: Carbohydrate antigen 125 (CA125) has been shown to be useful for risk stratification in patients admitted with acute heart failure (AHF). We sought to determine a CA125 cutpoint for identifying patients at low risk of 1-month death or the composite of death/HF readmission following admission for AHF. METHODS: The derivation cohort included 3231 consecutive patients with AHF. CA125 cutoff values with 90% negative predictive value (NPV) and sensitivity up to 85% were identified. The adequacy of these cutpoints and the risk of 1-month death/HF readmission was then tested using the Royston-Parmar method. The best cutpoint was selected and externally validated in a cohort of patients hospitalized from BIOSTAT-CHF (n=1583). RESULTS: In the derivation cohort, the median [IQR] CA125 was 57 [25.3-157] U/mL. The optimal cutoff value was <23 U/mL (21.5% of patients), with NPVs of 99.3% and 94.1% for death and the composite endpoint, respectively. On multivariate survival analyses, CA125 <23 U/mL was independently associated with a lower risk of death (HR, 0.20; 95%CI, 0.08-0.50; P <.001), and the combined endpoint (HR, 0.63; 95%CI, 950.45-0.90; P=.009). The ability of this cutpoint to discriminate patients at a low 1-month risk was confirmed in the validation cohort (NPVs of 98.6% and 96.6% for death and the composite endpoint). The predicted ability of this cutoff remained significant at 6 months of follow-up. CONCLUSIONS: In patients admitted with AHF, CA125 <23 U/mL identified a subgroup at low risk of short-term adverse events, a population that may not require intense postdischarge monitoring.

RESUMO

BACKGROUND: There are no well-established predictors of recurrent ischemic coronary events after an acute coronary syndrome (ACS). Higher levels of homocysteine have been reported to be associated with an increased atherosclerotic burden. The primary endpoint was to assess the relationship between homocysteine at discharge and very long-term recurrent myocardial infarction (MI). METHODS: 1306 consecutive patients with ACS were evaluated (862 with non-ST-segment elevation ACS [NSTEACS] and 444 with ST-segment elevation myocardial infarction [STEMI]) discharged from October 2000 to June 2003 in a single teaching-center. The relationship between homocysteine at discharge and recurrent MI was evaluated through bivariate negative binomial regression accounting for mortality as a competitive event. RESULTS: The mean age was 66.8 ± 12.4 years, 69.1% were men, and 32.2% showed prior diabetes mellitus. Most of the patients were admitted for an NSTEACS (66.0%). The median (interquartile range) GRACE risk score, Charlson comorbidity index, and homocysteine were 144 (122-175) points, 1 (1-2) points, and 11.9 (9.3-15.6) µmol/L, respectively. In-hospital revascularization was performed in 26.3% of patients. At a median follow-up of 9.7 (4.5-15.1) years, 709 (54.3%) deaths were registered and 779 recurrent MI in 478 (36.6%) patients. The rates of recurrent MI were higher in patients in the upper homocysteine quartiles (p < 0.001). After a multivariate adjustment, homocysteine along its continuum remained almost linearly associated with a higher risk of recurrent MI (p = 0.001) and all-cause mortality (p < 0.001). CONCLUSIONS: In patients with ACS, higher homocysteine levels identified those at a higher risk of recurrent MI at very long-term follow-up.

RESUMO

BACKGROUND: Identifying patients at risk of poor diuretic response in acute heart failure (AHF) is critical to make prompt adjustments in therapy. The objective of this study was to investigate whether the circulating levels of soluble ST2 predict the cumulative diuretic efficiency (DE) at 24 and 72 hours in patients with AHF and concomitant renal dysfunction. METHODS AND RESULTS: This is a post hoc analysis of the IMPROVE-HF trial, in which we enrolled 160 patients with AHF and renal dysfunction (estimated glomerular filtrate rate of <60 mL/min/1.73 m2). DE was calculated as the net fluid output produced per 40 mg of furosemide equivalents. The association between sST2 and DE was evaluated by using multivariate linear regression analysis. The median cumulative DE at 24 and 72 hour was 747 mL (interquartile range 490-1167 mL) and 1844 mL (interquartile range 1142-2625 mL), respectively. The median sST2 and mean estimated glomerular filtrate rate were 72 ng/mL (interquartile range 47-117 ng/mL), and 34.0 ± 8.5 mL/min/1.73 m2, respectively. In a multivariable setting, higher sST2 were significant and nonlinearly related to lower DE both at 24 and 72 hours (P = .002 and P = .019, respectively). CONCLUSIONS: In patients with AHF and renal dysfunction at presentation, circulating levels of sST2 were independently and negatively associated with a poor diuretic response, both at 24 and 72 hours.

RESUMO

AIMS: Type 2 diabetes mellitus (T2DM) is common in patients with heart failure (HF) and is related with worse outcomes. Insulin treatment is associated with sodium and water retention, weight gain, and hypoglycaemia-all pathophysiological mechanisms related to HF decompensation. This study aimed to evaluate the association between insulin treatment and the risk of 1 year readmission for HF in patients discharged for acute HF. METHODS AND RESULTS: We prospectively included 2895 consecutive patients discharged after an episode of acute HF in a single tertiary hospital. Multivariable Cox regression, adapted for competing events, was used to assess the association between insulin treatment and 1 year readmission for HF in patients discharged after acute HF. Participants' mean age was 73.4 ± 11.2 years, 50.8% were women, 44.7% had T2DM [including 527 (18.2%) on insulin therapy], and 52.7% had preserved ejection fraction. At 1 year follow-up, 518 (17.9%) patients had died and 693 (23.9%) were readmitted for HF. The crude risk of readmission for HF was higher in patients on insulin, with no differences in 1 year mortality. After multivariable adjustment, patients on insulin were at significantly higher risk of 1 year readmission for HF than patients with diabetes who were not on insulin (hazard ratio 1.28; 95% confidence interval 1.04-1.59, P = 0.022) and patients without diabetes (hazard ratio 1.26; 95% confidence interval 1.02-1.55, P = 0.035). CONCLUSION: Following acute HF, patients with T2DM on insulin therapy are at increased risk of readmission for HF. Further studies unravelling the mechanisms behind this association are warranted.

RESUMO

OBJECTIVE: In acute heart failure (AHF), early assessment of spot urinary sodium (UNa) has emerged as a useful biomarker for risk stratification and monitoring. The objective of this study was to investigate (a) whether early spot UNa predicts 24-h diuretic efficiency and (b) the clinical factors associated with early spot UNa in patients with AHF and concomitant renal dysfunction (RD). METHODS: This is a post hoc analysis of the IMPROVE-HF trial, in which 160 patients with AHF and RD (estimated glomerular filtrate rate [eGFR] <60 mL/min/1.73 m2) were included. Diuretic efficiency was calculated as the net fluid output produced per 40 mg of furosemide equivalents in 24 h. The association between early spot UNa and diuretic efficiency and clinical variables associated with UNa were evaluated using multivariate linear regression analysis. The contribution of the exposures in the predictability of the models was assessed with the coefficient of determination (R2). RESULTS: The mean age of the study population was 78 ± 8 years. The median (interquartile range) diuretic efficiency, early spot UNa, aminoterminal pro-brain natriuretic peptide, and eGFR were 747 (490-1,167) mL, 90 mmol/L (65-111), 7,765 pg/mL (3,526-15,369), and 33.7 ± 11.3 mL/min/1.73 m2, respectively. In a multivariate setting, lower UNa was significantly and nonlinearly associated with lower diuretic efficiency (p = 0.001), explaining the 44.4% of the model predictability. Natremia and surrogates of congestion emerged as the main factors related to UNa. CONCLUSIONS: In patients with AHF and RD at presentation, early spot UNa was inversely related to 24-h diuretic efficiency.

RESUMO

INTRODUCTION AND OBJECTIVES: Urinary sodium (UNa+) has emerged as a useful biomarker of poor clinical outcomes in acute heart failure (AHF). Here, we sought to evaluate: a) the usefulness of a single early determination of UNa+ for predicting adverse outcomes in patients with AHF and renal dysfunction, and b) whether the change in UNa+ at 24hours (ΔUNa24h) adds any additional prognostic information over baseline values. METHODS: This is a post-hoc analysis of a multicenter, open-label, randomized clinical trial (IMPROVE-HF) (ClinicalTrials.gov NCT02643147) that randomized 160 patients with AHF and renal dysfunction on admission to a) the standard diuretic strategy, or b) a carbohydrate antigen 125-guided diuretic strategy. The primary end point was all-cause mortality and total all-cause readmissions. RESULTS: The mean age was 78±8 years, and the mean glomerular filtration rate was 34.0±8.5mL/min/1.73 m2. The median UNa+ was 90 (65-111) mmol/L. At a median follow-up of 1.73 years [interquartile range, 0.48-2.35], 83 deaths (51.9%) were registered, as well as 263 all-cause readmissions in 110 patients. UNa+ was independently associated with mortality (HR, 0.75; 95%CI, 0.65-0.87; P <.001) and all-cause readmissions (HR, 0.92; 95%CI, 0.88-0.96; P <.001). The prognostic usefulness of the ΔUNa24h varied according to UNa+ at admission (P for interaction <.05). The ΔUNa24h was inversely associated with both end points only in the group with UNa+ ≤ 50 mmol/L. Conversely, no effect was found in the group with UNa+> 50 mmol/L. CONCLUSIONS: In patients with AHF and renal dysfunction, a single early determination of UNa+ ≤ 50 mmol/L identifies patients with a higher risk of all-cause mortality and readmission. The ΔUNa24h adds prognostic information over baseline values only when UNa+ at admission is ≤ 50 mmol/L.

RESUMO

BACKGROUND: Plasma amino-terminal pro-B-type natriuretic peptide and antigen carbohydrate 125 levels are positively associated with a higher risk of adverse clinical outcomes in acute heart failure. As a proxy of congestion, antigen carbohydrate 125 has also been proposed as a right-sided heart failure marker. Thus, we aimed to determine in this population the main factors - including echocardiographic right-sided heart failure parameters - associated with antigen carbohydrate 125 and amino-terminal pro-B-type natriuretic peptide. METHODS AND RESULTS: We prospectively included 2949 patients admitted with acute heart failure. Amino-terminal pro-B-type natriuretic peptide and antigen carbohydrate 125 were used as dependent variables in a multivariable linear regression analysis. The mean age of the sample was 73.9±11.1 years; 48.9% were female, 35.8% showed ischaemic aetiology, and 51.6% exhibited heart failure with preserved ejection fraction. The median (interquartile range) for amino-terminal pro-B-type natriuretic peptide and antigen carbohydrate 125 were 4840 (2111-9204) pg/ml and 58 (26-129) U/ml, respectively. In a multivariable setting, and ranked in order of importance (R2), estimated glomerular filtration rate (43.7%), left ventricle ejection fraction (15.1%), age (12.4%) and high-sensitivity troponin T (10.9%) emerged as the most important factors associated with amino-terminal pro-B-type natriuretic peptide. The five main factors associated with antigen carbohydrate 125 were, in order of importance: the presence of pleural effusion (36.8%), tricuspid regurgitation severity (25.1%), age (11.9%), amino-terminal pro-B-type natriuretic peptide (6.5%) and peripheral oedema (4.3%). CONCLUSION: In patients with acute heart failure the main factors associated with amino-terminal pro-B-type natriuretic peptide were renal dysfunction, left ventricle ejection fraction and age. For antigen carbohydrate 125, clinical parameters of congestion and the severity of tricuspid regurgitation were the most important predictors. These results endorse the value of antigen carbohydrate 125 as a useful marker of right-sided heart failure.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the association between antigen carbohydrate 125 (CA125) and the risk of 1-year clinical outcomes in patients with worsening heart failure (HF). BACKGROUND: CA125 is a widely available biomarker that is up-regulated in patients with acute HF and has been postulated as a useful marker of congestion and risk stratification. METHODS: In a large multicenter cohort of patients with worsening HF, either in-hospital or in the outpatient setting, the independent associations between CA125 and 1-year death and the composite of death/HF readmission (adjusted for outcome-specific prognostic risk score [BIOSTAT risk score]) were determined by using the Royston-Parmar method (N = 2,356). In a sensitivity analysis, the prognostic implications of CA125 were also adjusted for a composite congestion score (CCS). Data were validated in the BIOSTAT-CHF (Biology Study to Tailored Treatment in Chronic Heart Failure validation) cohort (N = 1,630). RESULTS: Surrogates of congestion, such as N-terminal pro-B-type natriuretic peptide and CCS, emerged as independent predictors of CA125. In multivariable survival analyses, higher CA125 was associated with an increased risk of mortality and the composite of death/HF readmission (p < 0.001 for both comparisons), even after adjustment for the CCS (p < 0.010 for both comparisons). The addition of CA125 to the BIOSTAT score led to a significant risk reclassification for both outcomes (category-free net reclassification improvement = 0.137 [p < 0.001] and 0.104 [p = 0.003] respectively). All outcomes were confirmed in an independent validation cohort. CONCLUSIONS: In patients with worsening HF, higher levels of CA125 were positively associated with parameters of congestion. Furthermore, CA125 remained independently associated with a higher risk of clinical outcomes, even beyond a predefined risk model and clinical surrogates of congestion.

RESUMO

Background Intravenous ferric carboxymaltose (FCM) improves symptoms, functional capacity, and quality of life in heart failure and iron deficiency. The mechanisms underlying these effects are not fully understood. The aim of this study was to examine changes in myocardial iron content after FCM administration in patients with heart failure and iron deficiency using cardiac magnetic resonance. Methods and Results Fifty-three stable heart failure and iron deficiency patients were randomly assigned 1:1 to receive intravenous FCM or placebo in a multicenter, double-blind study. T2* and T1 mapping cardiac magnetic resonance sequences, noninvasive surrogates of intramyocardial iron, were evaluated before and 7 and 30 days after randomization using linear mixed regression analysis. Results are presented as least-square means with 95% CI. The primary end point was the change in T2* and T1 mapping at 7 and 30 days. Median age was 73 (65-78) years, with N-terminal pro-B-type natriuretic peptide, ferritin, and transferrin saturation medians of 1690 pg/mL (1010-2828), 63 ng/mL (22-114), and 15.7% (11.0-19.2), respectively. Baseline T2* and T1 mapping values did not significantly differ across treatment arms. On day 7, both T2* and T1 mapping (ms) were significantly lower in the FCM arm (36.6 [34.6-38.7] versus 40 [38-42.1], P=0.025; 1061 [1051-1072] versus 1085 [1074-1095], P=0.001, respectively). A similar reduction was found at 30 days for T2* (36.3 [34.1-38.5] versus 41.1 [38.9-43.4], P=0.003), but not for T1 mapping (1075 [1065-1085] versus 1079 [1069-1089], P=0.577). Conclusions In patients with heart failure and iron deficiency, FCM administration was associated with changes in the T2* and T1 mapping cardiac magnetic resonance sequences, indicative of myocardial iron repletion.

RESUMO

BACKGROUND: In established ischemic heart disease, the relationship between lipoprotein(a) and new cardiovascular events showed contradictory results. Our aim was to assess the relationship between lipoprotein(a) and very long-term recurrent myocardial infarction (MI) after an index episode of ST-segment elevation acute myocardial infarction (STEMI). METHODS: We included 435 consecutive STEMI patients discharged from October 2000 to June 2003 in a single teaching center. The relationship between lipoprotein(a) at discharge and recurrent MI was evaluated through negative binomial regression and Cox regression analysis. RESULTS: The mean age was 65 years (55-74 years), 25.5% were women, 34.7% were diabetic, and 66% had a MI of anterior location. Fibrinolysis, rescue, or primary angioplasty was performed in 215 (49.4%), 19 (4.4%), and 18 (4.1%) patients, respectively. The median lipoprotein(a) was 30.4 mg/dL (12-59.4 mg/dL). After a median follow-up of 9.6 years (4.1-15 years), 180 (41.4%) deaths and 187 MI in 133 (30.6%) patients were recorded. After a multivariate adjustment, the risk gradient of lipoprotein(a) showed a neutral effect along most of the continuum and only extreme higher values identified those at higher risk of recurrent MI (P = 0.020). Those with lipoprotein(a) values >95th percentile (≥135 mg/dL) showed a higher risk of recurrent MI (incidence rate ratio, 2.34; 95% confidence interval, 1.37-4.02; P = 0.002). Lipoprotein(a) was not related to the risk of mortality (P = 0.245). CONCLUSIONS: After an episode of STEMI, only extreme high values of lipoprotein(a) were associated with an increased risk of long-term recurrent MI.

RESUMO

AIMS: Proprotein convertase subtilisin/kexin type 9 (PCSK9) has emerged as a therapeutic target for reducing plasma low-density lipoprotein cholesterol. Beyond lipid control, recent findings suggest a deleterious effect of this protein in the pathogenesis of postmyocardial infarction left ventricle remodelling and heart failure-related complications. The aim of this study was to assess the relationship between circulating PCSK9 and 6 month cardiac magnetic resonance imaging-derived left ventricular ejection fraction (LVEF) after a first ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS: We prospectively evaluated 40 patients with a first STEMI, LVEF < 50% and treated with primary percutaneous coronary intervention in which PCSK9 was measured 24 h postreperfusion. All patients underwent cardiac magnetic resonance imaging 1 week and 6 months after STEMI. Baseline characteristics were compared across median values of PCSK9. The association between PCSK9 levels and LVEF at 6 months was evaluated by analysis of covariance. The mean age of the sample was 60 ± 12 years and 33 (82.5%) were male patients. The infarct location was anterior in 27 patients (67.5%), and 9 patients (22.5%) were Killip class ≥ II. The mean 1 week and 6 month LVEF were 41 ± 7% and 48 ± 10%, respectively. The mean PCSK9 was 1.93 ± 0.38 U/mL. Testing the association between serum PCSK9 and 6 month LVEF with analysis of covariance revealed an inverse relationship (r = -0.35, P = 0.028). After multivariate adjustment, circulating PCSK9 remained significant and inversely associated with 6 month LVEF (P = 0.002). CONCLUSIONS: In patients with a first STEMI with reduced ejection fraction at index admission and treated with primary percutaneous coronary intervention, circulating PCSK9 was associated with lower LVEF at 6 months.

RESUMO

BACKGROUND: The optimal diuretic treatment strategy for patients with acute heart failure and renal dysfunction remains unclear. Plasma carbohydrate antigen 125 (CA125) is a surrogate of fluid overload and a potentially valuable tool for guiding decongestion therapy. The aim of this study was to determine if a CA125-guided diuretic strategy is superior to usual care in terms of short-term renal function in patients with acute heart failure and renal dysfunction at presentation. METHODS: This multicenter, open-label study randomized 160 patients with acute heart failure and renal dysfunction into 2 groups (1:1). Loop diuretics doses were established according to CA125 levels in the CA125-guided group (n = 79) and in clinical evaluation in the usual-care group (n = 81). Changes in estimated glomerular filtration rate (eGFR) at 72 and 24 hours were the co-primary endpoints, respectively. RESULTS: The mean age was 78 ± 8 years, the median amino-terminal pro-brain natriuretic peptide was 7765 pg/mL, and the mean eGFR was 33.7 ± 11.3 mL/min/1.73m2. Over 72 hours, the CA125-guided group received higher furosemide equivalent dose compared to usual care (P = 0.011), which translated into higher urine volume (P = 0.042). Moreover, patients in the active arm with CA125 >35 U/mL received the highest furosemide equivalent dose (P <0.001) and had higher diuresis (P = 0.013). At 72 hours, eGFR (mL/min/1.73m2) significantly improved in the CA125-guided group (37.5 vs 34.8, P = 0.036), with no significant changes at 24 hours (35.8 vs 39.5, P = 0.391). CONCLUSION: A CA125-guided diuretic strategy significantly improved eGFR and other renal function parameters at 72 hours in patients with acute heart failure and renal dysfunction.

RESUMO

AIMS: Iron deficiency (ID) is a frequent finding in patients with chronic and acute heart failure (AHF) along the full spectrum of left ventricular ejection fraction (LVEF). Iron deficiency has been related to ventricular systolic dysfunction, but its role in right ventricular function has not been evaluated. We sought to evaluate whether ID identifies patients with greater right ventricular dysfunction in the setting of AHF. METHODS AND RESULTS: We prospectively included 903 patients admitted with AHF. Right systolic function was evaluated by tricuspid annular plane systolic excursion (TAPSE) and the ratio TAPSE/pulmonary artery systolic pressure (TAPSE/PASP). Iron deficiency was defined, according to European Society of Cardiology criteria, as serum ferritin <100 mg/dL (absolute ID) or ferritin 100-299 mg/dL and transferrin saturation (TSAT) <20% (functional ID). The relationships among the exposures with right ventricular systolic function were evaluated by multivariate linear regression analyses. The mean age of the sample was 74.3 ± 10.6 years, 441 (48.8%) were female, 471 (52.2%) exhibited heart failure with preserved ejection fraction, and 677 (75.0%) showed ID. The mean LVEF, TAPSE, and TAPSE/PASP were 49 ± 15%, 18.6 ± 3.9 mm, and 0.45 ± 0.18, respectively. The median (interquartile range) amino-terminal pro-brain natriuretic peptide was 4015 (1807-8775) pg/mL. In a multivariable setting, lower TSAT and ferritin were independently associated with lower TAPSE (P < 0.05 for both comparisons). Transferrin saturation (P = 0.017), and not ferritin (P = 0.633), was independently associated with TAPSE/PASP. CONCLUSION: In AHF, proxies of ID were associated with right ventricular dysfunction. Further studies should confirm these findings and evaluate the pathophysiological facts behind this association.

RESUMO

Introducción y objetivos: La galectina-3 (Gal-3) y el antígeno carbohidrato 125 (CA125) han mostrado relación con eventos adversos tras el implante percutáneo de válvula aórtica (TAVI). Datos experimentales indican que podrían tener cierta interacción molecular. El objetivo del presente estudio es establecer la asociación de Gal-3 y CA125 con el pronóstico tras el TAVI. Métodos: Se incluyó en total a 439 pacientes. El objetivo primario fue el compuesto de mortalidad por todas las causas o reingreso por insuficiencia cardiaca tras el TAVI. Resultados: El objetivo primario se produjo en el 16,4% de la muestra. Los valores de Gal-3 se dicotomizaron en elevados (≥ 8,71 ng/ml) y no elevados. Los pacientes con Gal-3 elevado (31,9%) presentaron mayor riego de sufrir el objetivo primario (el 25 frente al 12,4%; HR=2,26; p<0,001). Tras el ajuste multivariable, la asociación entre Gal-3 y el pronóstico se situó en el límite de la significación (HR=1,59; p=0,068). En consecuencia, el CA125 se dicotomizó en ≥ 18,4 U/ml. El CA125 estaba elevado en el 51,9% y también se asoció con mayor riesgo del objetivo primario (el 25,4 frente al 6,6%; HR=4,20; p<0,001). Tras el ajuste multivariable, los valores de CA125 elevados (HR=2,83; p=0,001) mantenían la asociación independiente con el riesgo del objetivo primario. Se observó un efecto pronóstico diferencial para Gal-3 según los valores de CA125 (p de interacción=0,048). Así, los valores de Gal-3 elevados se asociaron significativamente con el pronóstico de los pacientes con CA125 elevado (el 38,8 frente al 18,2%; HR=2,02; p=0,015). Por el contrario, el Gal-3 no aportó información pronóstica con valores de CA125 bajos (el 6,6 frente al 6,7%; HR=1,16; p=0,981). Conclusiones: En pacientes sometidos a TAVI, los valores de Gal-3 se asociaron con mayor riesgo de eventos adversos clínicos solamente en presencia de valores de CA125 elevados


Introduction and objectives: Galectin-3 (Gal-3) and carbohydrate antigen 125 (CA125) have been associated with adverse outcomes after transcatheter aortic valve implantation (TAVI). Experimental data have suggested a potential molecular interaction. Therefore, we assessed the association of Gal-3 and CA125 with prognosis after TAVI. Methods: A total of 439 patients were enrolled. The primary endpoint was a composite of all-cause mortality or readmission for worsening heart failure after TAVI. Results: The primary endpoint occurred in 16.4%. Gal-3 was dichotomized at ≥ 8.71 ng/mL into elevated and not elevated. Gal-3 was elevated in 31.9% and was associated with a higher risk of the primary endpoint (25% vs 12.4%, HR, 2.26; P<.001). After multivariable adjustment, the association of elevated Gal-3 with the primary endpoint was borderline significant (HR, 1.59; P=.068). CA125 was dichotomized at ≥ 18.4 U/mL, accordingly. CA125 was elevated in 51.9% and was also associated with a higher risk of the primary endpoint (25.4% vs 6.6%, HR, 4.20; P<.001). After multivariable adjustment, elevated CA125 (HR, 2.83; P=.001) remained independently associated with the primary endpoint. A differential prognostic effect of Gal-3 was found across CA125 status (P for interaction=.048). Elevated Gal-3 was associated with a higher risk of the primary endpoint when CA125 was elevated (38.8% vs 18.2%, HR, 2.02; P=.015) but lacked significance when CA125 was not elevated (6.6% vs 6.7%, HR, 1.16; P=.981). Conclusions: In patients undergoing TAVI, Gal-3 predicted adverse clinical outcomes only when CA125 was elevated

RESUMO

Introducción y objetivos: Los pacientes con insuficiencia cardiaca en tratamiento con antagonistas de la vitamina K (AVK) por fibrilación auricular no valvular (FANV) a menudo presentan valores alterados de la razón internacional normalizada (INR). El objetivo es evaluar la asociación entre la INR al ingreso por insuficiencia cardiaca y el riesgo de mortalidad en el seguimiento. Métodos: Estudio observacional retrospectivo en el que se evaluó la INR al ingreso de 1.137 pacientes consecutivos con insuficiencia cardiaca aguda en tratamiento con AVK por FANV. Esta se categorizó en: INR en rango óptimo (INR = 2-3, n = 210), infraterapéutica (INR < 2, n = 660) o supraterapéutica (INR > 3, n = 267). La asociación independiente entre INR y mortalidad se evaluó mediante cálculo restringido de las diferencias en tiempos de supervivencia media, dado que la INR no cumple la condición de proporcionalidad de riesgos de mortalidad. Resultados: Tras una mediana de 2,15 [0,71-4,29] años, fallecieron 495 pacientes (43,5%). En el análisis multivariable, tanto la INR infraterapéutica como la supraterapéutica se asociaron con un mayor riesgo de mortalidad, con unas diferencias en tiempos de supervivencia media a 5 años de -0,50 años (IC95%,-0,77 a -0,23; p < 0,001) y -0,40 años (IC95%, -0,70 a -0,11; p = 0,007) con respecto a los pacientes con INR 2-3. Conclusiones: La INR fuera de rango óptimo al ingreso de los pacientes con insuficiencia cardiaca aguda en tratamiento con AVK por FANV se asocia de manera independiente con un mayor riesgo de mortalidad en el seguimiento a largo plazo


Introduction and objectives: Heart failure patients with nonvalvular atrial fibrillation (NVAF) on treatment with vitamin K antagonists (VKA) often have suboptimal international normalized ratio (INR) values. Our aim was to evaluate the association between INR values at admission due to acute heart failure and mortality risk during follow-up. Methods: In this observational study, we retrospectively assessed INR on admission in 1137 consecutive patients with acute heart failure and NVAF who were receiving VKA treatment. INR was categorized into optimal values (INR = 2-3, n = 210), subtherapeutic (INR < 2, n = 660), and supratherapeutic (INR > 3, n = 267). Because INR did not meet the proportional hazards assumption for mortality, restricted mean survival time differences were used to evaluate the association among INR categories and the risk of all-cause mortality. Results: During a median [interquartile range] follow-up of 2.15 years [0.71-4.29], 495 (43.5%) patients died. On multivariable analysis, both patients with subtherapeutic and supratherapeutic INR showed higher risks of all-cause mortality, as evidenced by their restricted mean survival time differences at 5 years' follow-up: -0.50; 95%CI, -0.77 to -0.23 years; P < .001; and -0.40; 95%CI, -0.70 to -0.11 years; P = .007, respectively, compared with INR 2-3. Conclusions: In acute heart failure patients on treatment with VKA for NVAF, INR values out of normal range at admission were independently associated with a higher long-term mortality risk

RESUMO

BACKGROUND: Functional tricuspid regurgitation (TR) is a common echocardiographic finding in patients with heart failure (HF), and its role in disease progression and prognosis stratification is becoming increasingly relevant in recent years. However, data regarding its association with the burden of HF-readmission is scarce. In this work, we sought to evaluate the association between TR severity and HF-related readmissions following a hospitalization for acute heart failure (AHF). METHODS: We prospectively included a cohort of 2101 patients admitted with the diagnosis of AHF. TR severity was assessed using a multiparametric integrative approach, and classified as none, mild, moderate, and severe. We used negative binomial regression to identify the association between TR grade and HF-related recurrent admissions. The risk associated to severity of TR was expressed as incidence rate ratio (IRR). RESULTS: At a median follow-up of 2.53 years (IQR: 1.03-4.36), 978 (46.5%) patients died, and 1657 HF-readmissions occurred in 842 patients (40.0%). The proportion of patients with two or more admissions was 18.4%. The proportion of patients with moderate to severe TR was 17.2%. There was a stepwise increase in the incidence of readmissions from none to severe TR. After multivariable adjustment, only patients with severe TR were independently associated with higher risk of recurrent HF admissions (IRR = 1.34, CI 95%: 1.05-1.71; p = .019). CONCLUSIONS: In patients with AHF, severe functional TR is independently associated with an increased risk of long-term recurrent HF hospitalizations.

RESUMO

Introducción y objetivos: No se dispone de tratamientos farmacológicos que demuestren reducir la morbimortalidad asociada en pacientes con insuficiencia cardiaca y función sistólica conservada (IC-FEc). El objetivo del presente estudio fue evaluar si en pacientes con IC-FEc, el entrenamiento de la musculatura inspiratoria (EMI), la electroestimulación muscular funcional (EMF) o la combinación de ambas (EMI + EMF) puede mejorar la capacidad funcional, calidad de vida, parámetros de disfunción diastólica o biomarcadores a las 12 y 24 semanas. Métodos: Un total de 61 pacientes estables con IC-FEc (clase funcional de la New York Heart Association II-III) se aleatorizaron (1:1:1:1) a recibir un programa de 12 semanas de EMI, EMF, o EMI + EMF frente a tratamiento médico estándar (control). El objetivo primario fue evaluar el cambio en el consumo máximo de oxígeno. Los objetivos secundarios fueron los cambios en la calidad de vida, parámetros ecocardiográficos y biomarcadores. Se utilizó un modelo lineal mixto para comparar los cambios entre los diferentes grupos. Resultados: La edad media fue 74 +/- 9 años y la proporción de mujeres fue del 58%. El test de consumo máximo de oxígeno fue de 9,9 +/- 2,5ml/min/kg. A las 12 semanas, con respecto al grupo control, el incremento medio de consumo máximo de oxígeno fue de 2,98, 2,93 y 2,47 para EMI, EMF y EMI + EMF, respectivamente (p < 0,001). Este incremento se mantuvo a las 24 semanas (1,95, 2,08 y 1,56, respectivamente; p < 0,001). Resultados similares se observaron en la puntuación del cuestionario de calidad de vida (p < 0,001). Conclusiones: En los pacientes con IC-FEc e importante reducción de la capacidad funcional, tanto el EMI como la EMF se asocian con una marcada mejoría de la capacidad funcional y la calidad de vida


Introduction and objectives: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. Methods: A total of 61 stable symptomatic patients (New York Heart Association functional class II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care. The primary endpoint of the study was to evaluate change in peak exercise oxygen uptake at 12 and 24 weeks. Secondary endpoints were changes in quality of life, echocardiogram parameters, and prognostic biomarkers. We used a mixed-effects model for repeated-measures to compare endpoints changes. Results: Mean age and peak exercise oxygen uptake were 74 +/- 9 years and 9.9 +/- 2.5mL/min/kg, respectively. The proportion of women was 58%. At 12 weeks, the mean increase in peak exercise oxygen uptake (mL/kg/min) compared with usual care was 2.98, 2.93, and 2.47 for IMT, FES, and IMT + FES, respectively (P < .001) and this beneficial effect persisted after 24 weeks (1.95, 2.08, and 1.56; P < .001). Significant increases in quality of life scores were found at 12 weeks (P < .001). No other changes were found. Conclusions: In HFpEF patients with low aerobic capacity, IMT and FES were associated with a significant improvement in exercise capacity and quality of life

RESUMO

INTRODUCTION AND OBJECTIVES: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. METHODS: A total of 61 stable symptomatic patients (New York Heart Association II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care. The primary endpoint of the study was to evaluate change in peak exercise oxygen uptake at 12 and 24 weeks. Secondary endpoints were changes in quality of life, echocardiogram parameters, and prognostic biomarkers. We used a mixed-effects model for repeated-measures to compare endpoints changes. RESULTS: Mean age and peak exercise oxygen uptake were 74 ± 9 years and 9.9 ± 2.5mL/min/kg, respectively. The proportion of women was 58%. At 12 weeks, the mean increase in peak exercise oxygen uptake (mL/kg/min) compared with usual care was 2.98, 2.93, and 2.47 for IMT, FES, and IMT + FES, respectively (P < .001) and this beneficial effect persisted after 6 months (1.95, 2.08, and 1.56; P < .001). Significant increases in quality of life scores were found at 12 weeks (P < .001). No other changes were found. CONCLUSIONS: In HFpEF patients with low aerobic capacity, IMT and FES were associated with a significant improvement in exercise capacity and quality of life. This trial was registered at ClinicalTrials.gov (Identifier: NCT02638961)..
