RESUMO

BACKGROUND: Congestion is an essential issue in patients with heart failure (HF). Standard treatments do not usually achieve decongestion, and various strategies have been proposed to guide treatment, such as determination of natriuresis. After starting treatment with loop diuretics, we postulate that initial natriuresis might help treatment titration, decongestion, and improve prognosis. METHODS: It was a prospective and observational study. Patients admitted with the diagnosis of HF decompensation were eligible. An assessment of congestion was performed during the first 48 h. RESULTS: A total of 113 patients were included. A poor diuretic response was observed in 39.8%. After the first 48 h, patients with a greater diuretic response on admission (NaU > 80 mmol/L) showed fewer pulmonary b lines (12 vs. 15; p = 0.084), a lower IVC diameter (18 mm vs. 22 mm; p = 0.009), and lower IAP figures (11 mmHg vs. 13 mmHg; p = 0.041). Survival analysis tests demonstrated significant differences showing a higher proportion of all-cause mortality (ACM) and HF rehospitalization in the poor-diuretic-response group (log-rank test = 0.020). CONCLUSIONS: Up to 40% of the patients presented a poorer diuretic response at baseline, translating into worse outcomes. Patients with an optimal diuretic response showed significantly higher abdominal decongestion at 48 h and a better prognosis regarding ACM and/or HF rehospitalizations.

RESUMO

BACKGROUND: We aimed to characterise and compare the clinical profile of heart failure (HF) with mid-range (HFmrEF), reduced (HFrEF) and preserved (HFpEF) left-ventricular ejection fraction. METHODS: We conducted a descriptive, observational study in 267 HF patients admitted to the Internal Medicine department of a tertiary hospital during 2010-2016. The study population was divided into three groups according to the ejection fraction rate: HFrEF (<40%), HFmrEF (40-49%), and HFpEF (≥50%). We analysed and compared their demographic, clinical, and analytical characteristics. RESULTS: The mean age of the study population was 79.5 (standard deviation, 8.14) years; 56.6% were males. The most common phenotype was HFpEF (58.1%), followed by HFrEF (21.7%) and HFmrEF (20.2%). Ischaemic cardiopathy was the primary aetiology in the HFmrEF and HFrEF groups, and arterial hypertension in the HFpEF group. The most common comorbidities among HFmrEF patients were diabetes (43.4%), chronic obstructive pulmonary disease (35.8%), and anaemia (35.8%); 49.1% had impairment of segmental myocardial contractility, and 35.8% ventricular dilatation. No differences in HF outcomes were observed among the three phenotypes. CONCLUSION: HFmrEF shows characteristics similar to both HFpEF and HFrEF. Further large-scale studies with longer follow-up are needed to ascertain if it is worth distinguishing this phenotype in clinical practice in terms of management and prognosis.

RESUMO

BACKGROUND: Risk stratification of COVID-19 patients is fundamental to improving prognosis and selecting the right treatment. We hypothesized that a combination of lung ultrasound (LUZ-score), biomarkers (sST2), and clinical models (PANDEMYC score) could be useful to improve risk stratification. METHODS: This was a prospective cohort study designed to analyze the prognostic value of lung ultrasound, sST2, and PANDEMYC score in COVID-19 patients. The primary endpoint was in-hospital death and/or admission to the intensive care unit. The total length of hospital stay, increase of oxygen flow, or escalated medical treatment during the first 72 h were secondary endpoints. RESULTS: a total of 144 patients were included; the mean age was 57.5 ± 12.78 years. The median PANDEMYC score was 243 (52), the median LUZ-score was 21 (10), and the median sST2 was 53.1 ng/mL (30.9). Soluble ST2 showed the best predictive capacity for the primary endpoint (AUC = 0.764 (0.658-0.871); p = 0.001), towards the PANDEMYC score (AUC = 0.762 (0.655-0.870); p = 0.001) and LUZ-score (AUC = 0.749 (0.596-0.901); p = 0.002). Taken together, these three tools significantly improved the risk capacity (AUC = 0.840 (0.727-0.953); p ≤ 0.001). CONCLUSIONS: The PANDEMYC score, lung ultrasound, and sST2 concentrations upon admission for COVID-19 are independent predictors of intra-hospital death and/or the need for admission to the ICU for mechanical ventilation. The combination of these predictive tools improves the predictive power compared to each one separately. The use of decision trees, based on multivariate models, could be useful in clinical practice.

RESUMO

BACKGROUND: Lung ultrasound is feasible for assessing lung injury caused by coronavirus disease 2019 (COVID-19). However, the prognostic meaning and time-line changes of lung injury assessed by lung ultrasound in COVID-19 hospitalised patients are unknown. METHODS: Prospective cohort study designed to analyse prognostic value of lung ultrasound in COVID-19 patients by using a quantitative scale (lung ultrasound Zaragoza (LUZ)-score) during the first 72 h after admission. The primary end-point was in-hospital death and/or admission to the intensive care unit. Total length of hospital stay, increase of oxygen flow and escalation of medical treatment during the first 72 h were secondary end-points. RESULTS: 130 patients were included in the final analysis; mean±sd age was 56.7±13.5 years. Median (interquartile range) time from the beginning of symptoms to admission was 6 (4-9) days. Lung injury assessed by LUZ-score did not differ during the first 72 h (21 (16-26) points at admission versus 20 (16-27) points at 72 h; p=0.183). In univariable logistic regression analysis, estimated arterial oxygen tension/inspiratory oxygen fraction ratio (PAFI) (hazard ratio 0.99, 95% CI 0.98-0.99; p=0.027) and LUZ-score >22 points (5.45, 1.42-20.90; p=0.013) were predictors for the primary end-point. CONCLUSIONS: LUZ-score is an easy, simple and fast point-of-care ultrasound tool to identify patients with severe lung injury due to COVID-19, upon admission. Baseline score is predictive of severity along the whole period of hospitalisation. The score facilitates early implementation or intensification of treatment for COVID-19 infection. LUZ-score may be combined with clinical variables (as estimated by PAFI) to further refine risk stratification.

RESUMO

Heart failure (HF) is becoming increasingly prevalent and affects both men and women. However, women have traditionally been underrepresented in HF clinical trials. In this study, we aimed to analyze sex differences in the comorbidity, therapy, and health services' use of HF patients. We conducted a cross-sectional study in Aragón (Spain) and described the characteristics of 17,516 patients with HF. Women were more frequent (57.4 vs. 42.6%, p < 0.001) and older (83 vs. 80 years, p < 0.001) than men, and presented a 33% lower risk of 1-year mortality (p < 0.001). Both sexes showed similar disease burdens, and 80% suffered six or more diseases. Some comorbidities were clearly sex-specific, such as arthritis, depression, and hypothyroidism in women, and arrhythmias, ischemic heart disease, and COPD in men. Men were more frequently anti-aggregated and anti-coagulated and received more angiotensin-converting-enzyme (ACE) inhibitors and beta-blockers, whereas women had more angiotensin II antagonists, antiinflammatories, antidepressants, and thyroid hormones dispensed. Men were admitted to specialists (79.0 vs. 70.6%, p < 0.001), hospital (47.0 vs. 38.1%, p < 0.001), and emergency services (57.6 vs. 52.7%, p < 0.001) more frequently than women. Our results highlight the need to conduct future studies to confirm the existence of these differences and of developing separate HF management guidelines for men and women that take into account their sex-specific comorbidity.

RESUMO

OBJECTIVES: To characterise the comorbidities of heart failure (HF) in men and women, to explore their clustering into multimorbidity patterns, and to measure the impact of such patterns on the risk of hospitalisation and mortality. DESIGN: Observational retrospective population study based on electronic health records. SETTING: EpiChron Cohort (Aragón, Spain). PARTICIPANTS: All the primary and hospital care patients of the EpiChron Cohort with a diagnosis of HF on 1 January 2011 (ie, 8488 women and 6182 men). We analysed all the chronic diseases registered in patients' electronic health records until 31 December 2011. PRIMARY OUTCOME: We performed an exploratory factor analysis to identify the multimorbidity patterns in men and women, and logistic and Cox proportional-hazards regressions to investigate the association between the patterns and the risk of hospitalisation in 2012, and of 3-year mortality. RESULTS: Almost all HF patients (98%) had multimorbidity, with an average of 7.8 chronic diseases per patient. We identified six different multimorbidity patterns, named cardiovascular, neurovascular, coronary, metabolic, degenerative and respiratory. The most prevalent were the degenerative (64.0%) and cardiovascular (29.9%) patterns in women, and the metabolic (49.3%) and cardiovascular (43.2%) patterns in men. Every pattern was associated with higher hospitalisation risks; and the cardiovascular, neurovascular and respiratory patterns significantly increased the likelihood of 3-year mortality. CONCLUSIONS: Multimorbidity is the norm rather than the exception in patients with heart failure, whose comorbidities tend to cluster together beyond simple chance in the form of multimorbidity patterns that have different impact on health outcomes. This knowledge could be useful to better understand common pathophysiological pathways underlying this condition and its comorbidities, and the factors influencing the prognosis of men and women with HF. Further large scale longitudinal studies are encouraged to confirm the existence of these patterns as well as their differential impact on health outcomes.

RESUMO

Acute heart failure (HF) is a prevalent disease with important socio-economic repercussions. Due to the aging of population, these values will increase in the coming years, so it may be useful to the implementation of intervention programs in these patients to decrease morbidity and mortality. A quasi-experimental prospective study (n = 262) of patients admitted at the Internal Medicine Department of the Hospital Clínico Universitario Lozano Blesa, in Zaragoza, Spain, diagnosed of HF between November 2013 and October 2014 (both dates inclusive) (n = 108) followed up for 1 year was performed. Within this group, a subgroup with an intensive intervention (n = 30) was performed. The data were compared with a historical cohort of patients admitted to the same department during the same time in the previous year (from November 2012 to October 2013) (n = 154). Statistically significant differences between groups attending to the therapeutical adherence to clinical guidelines (p < 0.011) were observed. Considering the intensive intervention subgroup, statistically significant differences were observed in the rate of exitus (p < 0.032) and survival (log rank <0.030) compared to the control group. The close monitoring of patients with HF improves adherence, reduces mortality and improves survival. This May result in a decline in the use of health resources, which entails significant socio-economic benefits.

RESUMO

Fundamento y objetivo: Existe una relación inversa entre las cifras de presión arterial en las descompensaciones y el pronóstico de la insuficiencia cardiaca (IC). Las características de esta relación no son bien conocidas. El objetivo del estudio fue analizar si esta relación se mantiene en una cohorte no seleccionada de pacientes con IC y si el tratamiento la modifica. Material y métodos: Estudio prospectivo de cohortes de pacientes ingresados por IC descompensada en un servicio de Medicina Interna y seguidos ambulatoriamente en una consulta monográfica. Los pacientes fueron agrupados en función de la presión arterial sistólica (PAS) y diastólica (PAD); se analizaron las características clínicas, la mortalidad global y los reingresos al primer, tercer y sexto mes de seguimiento. Resultados: Se incluyeron 221 pacientes tras un ingreso índice por IC. Media de edad: 79,5 años (DE 8,09); varones: 115. No hubo diferencias significativas en las características basales de los pacientes en función de los cuartiles de PAS. Los pacientes con menor PAS (Q1) tenían mayor mortalidad (20%, p<0,05). No se encontraron diferencias para la PAD. Sin embargo, el análisis de Kaplan-Meier mostró una mayor mortalidad global en los pacientes con menor PAS y PAD (log-rank=0,011 y 0,041, respectivamente). Las características del tratamiento farmacológico no diferían entre los grupos del estudio. Conclusión: En pacientes con IC no seleccionados, las cifras elevadas de PAS al ingreso se asocian con una menor mortalidad durante el seguimiento. El tratamiento farmacológico de la IC no parece influir en la relación inversa entre la PAS al ingreso y la mortalidad (AU)


Background and objective: An inverse relationship has been described between blood pressure and the prognosis in heart failure (HF). The characteristics of this relationship are not well unknown. The objective of this study was to determine if this relationship is maintained in a non-selected cohort of patients with HF and if it can be modified by treatment. Material and methods: Prospective study of cohorts including patients hospitalized for decompensated HF in Internal Medicine departments and followed as outpatients in a monographic consultation. Patients were classified according to their levels of systolic (SBP) and diastolic blood pressure (DBP). Clinical characteristics, all-cause mortality and readmissions after the first, third and sixth month of follow-up were analysed. Results: Two hundred and twenty-one patients were included after their admission to the hospital for acute HF. Mean patient age was 79.5 years(SD 8.09); 115 patients were male. No significant differences between SBP quartiles and basal characteristics were found. Patients with lower SBP (Q1) had higher mortality rates (20%, P<.05). No significant differences between mortality/readmissions and DBP were found. However, the Kaplan-Meier analysis showed higher all-cause mortality rates for the group of patients with lower SBP and DBP (log-rank=0.011 and 0.041, respectively). The pharmacological treatment did not differ significantly between both study groups. Conclusion: For non-selected patients suffering HF, higher SBP upon the admission is associated with significantly lower all-cause mortality rates during follow-up. Pharmacological treatment of HF does not seem to influence this inverse relationship between SBP at admission and patient mortality (AU)

RESUMO

AIM: To evaluate precipitating factors (PF) of exacerbation in heart failure (HF) and their relationship with age, preserved vs. reduced left ventricular ejection fraction (LVEF) and short-term prognosis. METHODS: We included and followed 2962 patients admitted with acute HF to Internal Medicine Units. Several PF were identified. Differences in PF according to preserved vs. reduced LVEF and age (patients≥80years vs. younger) were analyzed. Primary endpoints were readmission due to worsening HF and all-cause mortality at 3months follow-up. Multivariable Cox models were conducted to identify the independent predictors of 3-months mortality and readmission. RESULTS: More than half of the patients were 80years and over, 47% were women and 61% had preserved LVEF. Atrial fibrillation (AF) and myocardial ischemia were the more common cause of decompensation among octogenarians. It was more frequent to find myocardial ischemia or non-adherence to treatment as precipitants in patients with systolic dysfunction. However, respiratory infections, AF and poor control of blood pressure were more usual in patients with preserved LVEF compared to those with LVEF <50%. Patients admitted for HF precipitated by myocardial ischemia had a higher risk of readmission at 3months (HR 1.49; CI 95%: 1.12-1.99, p=0.006) and the longest hospital stay (12days). PF showed no predictive value for mortality. CONCLUSION: Myocardial ischemia as a PF was an independent marker for HF readmissions at 3-months follow-up. Precipitants are different depending on the age and LVEF of patients. Their identification could improve risk stratification and prevention strategies.

RESUMO

Los fármacos vasoactivos en inotrópicos proporcionan un eficaz alivio sintomático y hemodinámico a corto plazo, aunque a largo plazo su uso puede aumentar la mortalidad, por lo que su utilización debe estar restringida a las indicaciones que de ellos hacen las guías de práctica clínica. En este capítulo se revisan los principales fármacos y las evidencias que de ellos disponemos (AU)


Vasoactive and inotropic drugs provide effective symptomatic and hemodynamic relief in the short term but can increase mortality in the long-term. Consequently, their use should be restricted to the indications described in clinical practice guidelines. The present article reviews the main drugs and the available evidence on their use (AU)

RESUMO

BACKGROUND: Many elderly heart failure (HF) patients show some degree of functional impairment. The study aim was to evaluate the functional status of oldest-old cohort of patients hospitalized with a diagnosis of decompensated (HF), and to analyze whether preadmission functional status predicts risk of 3-month mortality. METHODS: We analyzed 1431 elderly (≥ 75 years) patients prospectively included in the Spanish National Registry on HF (RICA). We added Barthel Index (BI) to the usual HF patient assessment to measure patients' functional status, and we evaluated the relationship between preadmission BI values and 3-month mortality. RESULTS: The mean age of patients was 82.3 (4.6) years. Patients' mean preadmission BI score was 81.3 (21.5); 802 patients (55.9%) had BI scores <61. Multivariate analysis confirmed an independent association between poor preadmission BI and older age, female sex, higher comorbidity, cognitive impairment, previous institutionalization, worse New York Heart Association (NYHA) functional class and lack of beta-blocker use. A total of 210 patients died (14.7%) after 3 months of follow-up. Cox multivariate analyses found that higher preadmission BI is correlated with reduced all-cause, 3-month postdischarge mortality [hazard ratio (HR) 0.981; CI95% 0.975-0.986, p<0.001]. Other variables independently associated with 3-month mortality were male sex, lower body mass index, lower systolic blood pressure, a diagnosis of diabetes and chronic kidney disease, worse NYHA class and not receiving treatment with beta-blockers. CONCLUSIONS: Severe functional disability is present among more than half of older patients admitted because of a HF decompensation. For this population, preadmission BI is a strong predictor of short-term mortality.

RESUMO

Fundamentos y objetivo: Los péptidos natriuréticos (PN) han demostrado su utilidad en la insuficiencia cardiaca (IC) y algunos trastornos de la circulación pulmonar. El presente trabajo tiene por objeto conocer la utilidad de la fracción aminoterminal del péptido natriurético cerebral (NT-proBNP) como marcador pronóstico en pacientes con enfermedad pulmonar crónica reagudizada, sin semiología clínica de IC. Pacientes y método: Estudio prospectivo y observacional. Se incluyeron de forma consecutiva 192 pacientes con enfermedad pulmonar crónica ingresados por descompensación de su enfermedad respiratoria. Se determinó la concentración sanguínea de NT-proBNP en todos ellos y se realizó posteriormente un seguimiento durante los 6 meses posteriores al ingreso para detectar reingresos, prescripción de diuréticos, oxigenoterapia o muerte.Resultados: El 6,3% de los pacientes fallecieron, en un 22,9% se prescribió oxigenoterapia, en un 18,2% diuréticos y el 21,9% reingresó al menos en una ocasión durante el período de seguimiento de 6 meses. La concentración media de NT-proBNP fue de 1180pg/ml. Concentraciones de NT-proBNP superiores a 500pg/ml (odds ratio [OR] 11,0, intervalo de confianza del 95% [IC 95%] 1,39–86,99) y de 350pg/ml fueron predictoras de mortalidad y prescripción de diurético (OR 2,83; IC 95% 1,16–6,86), respectivamente. Conclusiones: El NT-proBNP podría ser un marcador pronóstico en pacientes con enfermedad pulmonar crónica, identificando a aquellos con especial riesgo de fallecer o más probabilidad de desarrollar una disfunción ventricular sintomática (AU)


Background and objective: Brain natriuretic peptide (BNP) is produced and released mainly from ventricles. BNP has been shown to be useful in diagnosis and prognosis in heart failure and some pulmonary conditions. The aim of this study is to analyse whether NT-proBNP has a prognostic value in chronic pulmonary patients without overt heart failure. Patient and method: We conducted an observational and prospective study. We included 192 patients admitted to the Internal Medicine Departments of Hospital Clinico “Lozano Blesa” (Zaragoza, Spain) and “Virgen de la Luz” (Cuenca, Spain) with acute exacerbation of pulmonary disease. Blood samples were taken to determine NT-proBNP concentrations. All patients were followed for 6 months after admission.Results: 6,3% of patients died, 22,9% were prescribed with home oxygen-therapy, 18,2% received a diuretic prescription and 21,9% were re-admitted at least once during the follow-up period. Mean NT-proBNP was 1180pg/ml. A concentration above 500pg/ml and 350pg/ml of NT-proBNP was useful to predict mortality and diuretic prescription respectively.Conclusions: Among patients with acute exacerbations of chronic pulmonary disease, NT-proBNP could be a prognostic factor to identify those at risk of death or worst clinical development (AU)

RESULTS: 6,3% of patients died, 22,9% were prescribed with home oxygen-therapy, 18,2% received a diuretic prescription and 21,9% were re-admitted at least once during the follow-up period. Mean NT-proBNP was 1180pg/ml. A concentration above 500pg/ml and 350pg/ml of NT-proBNP was useful to predict mortality and diuretic prescription respectively. CONCLUSIONS: Among patients with acute exacerbations of chronic pulmonary disease, NT-proBNP could be a prognostic factor to identify those at risk of death or worst clinical development.

RESUMO

BACKGROUND: Changes in extracellular matrix are recognized as a contributing factor in the cardiac remodeling process. Several studies have addressed the value of turnover markers of collagen as predictors of death or new heart failure episodes. The aim of the present study was to evaluate the relationship between peripheral serum concentration of propeptide of procollagen type I (PIP) and outcomes in patients with decompensated heart failure. METHODS: A total of 111 patients admitted to our Unit between September 2000 and May 2003 for decompensated heart failure were analyzed. Death from any cause or due to heart failure and readmission were considered primary endpoints. RESULTS: The mean PIP concentration was 80.84+/-36.40 ng/mL. The PIP serum level was significantly higher among those patients who suffered some endpoint during follow-up (88.12+/-37.31 ng/mL vs 73.13+/-34.06 ng/mL; p=0.029). Twenty-five (22.52%) of the 111 patients died during the 21 months of follow-up, and 54 (48.6%) were readmitted with new bouts of heart failure. Using Cox proportional hazards regression analyses, serum PIP levels, systolic dysfunction, and diabetes mellitus were identified as independent predictors of death. Serum PIP levels, age, and sex were independent predictors of new heart failure episodes and readmission. CONCLUSION: A single serum measurement of PIP seems to have prognostic value in patients with decompensated heart failure. Accordingly, patients with higher values of PIP at decompensation are at a higher risk of death or readmission during follow-up.
