RESUMO

Acute heart failure (AHF) is a highly prevalent clinical entity in individuals older than 45years in Spain. AHF is associated with significant morbidity and mortality and is the leading cause of hospitalisation for individuals older than 65years in Spain, a quarter of whom die within 1year of the hospitalisation. In recent years, there has been an upwards trend in hospitalisations for AHF, which increased 76.7% from 2003 to 2013. Readmissions at 30days for AHF have also increased (from 17.6% to 22.1%), at a relative mean rate of 1.36% per year, with the consequent increase in the use of resources and the economic burden for the healthcare system. The aim of this document (developed by the Heart Failure and Atrial Fibrillation Group of the Spanish Society of Internal Medicine) is to guide specialists on the most important aspects of treatment and follow-up for patients with AHF during hospitalisation and the subsequent follow-up. The main recommendations listed in this document are as follows: (1)At admission, perform a comprehensive assessment, considering the patient's standard treatment and comorbidities, given that these determine the disease prognosis to a considerable measure. (2)During the first few hours of hospital care, decongestive treatment is a priority, and a staged diuretic therapeutic approach based on the patient's response is recommended. (3)To manage patients in the stable phase, consider starting and/or adjusting evidence-based drug treatment (e.g., sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensinII receptor blockers, beta blockers and aldosterone antagonists). (4)At hospital discharge, use a checklist to optimise the patient's management and identify the most efficient options for maintaining continuity of care after discharge.

RESUMO

AIMS: The addition of hydrochlorothiazide (HCTZ) to furosemide improved the diuretic response in patients with acute heart failure (AHF) in the CLOROTIC trial. Our aim was to evaluate if there were differences in clinical characteristics and outcomes according to sex. METHODS: This is a post-hoc analysis of the CLOROTIC trial, including 230 patients with AHF randomized to receive HCTZ or placebo in addition to an intravenous furosemide regimen. The primary and secondary outcomes included changes in weight and patient-reported dyspnoea 72 and 96 h after randomization, metrics of diuretic response and mortality/rehospitalizations at 30 and 90 days. The influence of sex on primary, secondary and safety outcomes was evaluated. RESULTS: One hundred and eleven (48%) women were included in the study. Women were older and had higher values of left ventricular ejection fraction. Men had more ischemic cardiomyopathy and chronic obstructive pulmonary disease and higher values of natriuretic peptides. The addition of HCTZ to furosemide was associated to a greatest weight loss at 72/96 h, better metrics of diuretic response and higher 24-h diuresis compared to placebo without significant differences according to sex (all p-values for interaction were not significant). Worsening renal function occurred more frequently in women (OR [95%CI]: 8.68 [3.41-24.63]) than men (OR [95%CI]: 2.5 [0.99-4.87]), p = 0.027. There were no differences in mortality or rehospitalizations at 30/90 days. CONCLUSION: Adding HCTZ to intravenous furosemide is an effective strategy to improve diuretic response in AHF with no difference according to sex, but worsening renal function was more frequent in women. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov: NCT01647932; EudraCT Number: 2013-001852-36.

RESUMO

Acute heart failure (AHF) is associated with significant morbidity and mortality and it stands as the primary cause of hospitalization for individuals over the age of 65 in Spain. This document outlines the main recommendations as follows: (1) Upon admission, it is crucial to conduct a comprehensive assessment, taking into account the patient's standard treatment and comorbidities, as these factors determine the prognosis of the disease. (2) During the initial hours of hospital care, prioritizing decongestive treatment is essential. It is recommended to adopt an early staged diuretic therapeutic approach based on the patient's response. (3) In order to manage patients in the stable phase, it is advisable to consider initiating and/or adjusting evidence-based drug treatments such as sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta blockers, aldosterone antagonists, and SGLT2 inhibitors. (4) Upon hospital discharge, utilizing a checklist is recommended to optimize the patient's management and identify the most efficient options for ensuring continuity of care post-discharge.

RESUMO

BACKGROUND AND AIMS: The prognostic role of pulse pressure (PP) in heart failure (HF) patients with preserved left ventricular ejection fraction (LVEF) is not well understood. Our aim was to evaluate it in acute and stable HF. MATERIAL AND METHODS: This work is a retrospective observational study of patients included in the RICA registry between 2008 and 2021. Blood pressure was collected on admission (decompensation) and 3 months later on an outpatient basis (stability). Patients were categorized according to whether the PP was greater or less than 50mmHg. All-cause mortality was assessed at 1year after admission. RESULTS: A total of 2291 patients were included, with mean age 80.1±7.7 years. 62.9% were women and 16.7% had a history of coronary heart disease. In the acute phase, there was no difference in mortality according to PP values, but in the stable phase PP<50mmHg was independently associated with all-cause mortality at 1-year follow-up (HR 1.57, 95% CI 1.21-2.05, p=0.001), after adjusting for age, sex, New York Heart Association functional class, previous HF, chronic kidney disease, valvular heart disease, cerebrovascular disease, score on the Barthel and Pfeiffer scales, hemoglobin and sodium levels. CONCLUSIONS: Low stable-phase PP was associated with increased all-cause mortality in HF patients with preserved LVEF. However, PP was not useful as a prognostic marker of mortality in acute HF. Further studies are needed to assess the relationship of this variable with mortality in HF patients.

RESUMO

AIMS: Heart failure (HF) and diabetes are 2 strongly associated diseases. The main objective of this work was to analyze changes in the prognosis of patients with diabetes who were admitted for heart failure in 2 time periods. METHODS: This work is a prospective study comparing prognosis at one year of follow-up among patients with diabetes who were hospitalized for HF in either 2008-2011 or 2018. The patients are from the Spanish Society of Internal Medicine's National Heart Failure Registry (RICA, for its initials in Spanish). The primary endpoint was to analyze the composite outcome of total mortality and/or readmission due to HF in 12 months. A multivariate Cox regression model was used to evaluate the strength of association (hazard ratio [HR]) between diabetes and the outcomes between both periods. RESULTS: A total of 936 patients were included in the 2018 cohort, of which 446 (48%) had diabetes. The baseline characteristics of the populations from the 2 periods were similar. In patients with diabetes, the composite outcome was observed in 233 (47.5%) in the 2008-2011 cohort and 162 (36%) in the 2018 cohort [HR 1.48; 95% confidence interval (95%CI) 1.18-1.85; p < .001]. The proportion of readmissions (HR 1.39; 95%CI 1.07-1.80; p = .015) and total mortality (HR 1.60; 95%CI 1.20-2.14; p < .001) were also significantly higher in patients with diabetes from the 2008-2011 cohort compared to the 2018 cohort. CONCLUSIONS: In 2018, an improvement was observed in the prognosis for all-cause mortality and readmissions over one year of follow-up in patients with diabetes hospitalized for HF compared to the 2008-2011 period.

RESUMO

INTRODUCTION AND OBJECTIVES: Given the proven protective effect of the Mediterranean Diet, adherence to it by healthcare personnel and the influence of different factors on dietary compliance were evaluated. METHODS: A cross-sectional study was conducted on healthcare personnel, obtaining the data through anonymous surveys that collected demographic characteristics, professional activity, history of cardiovascular risk factors, alcohol, and tobacco consumption, physical activity, and adherence to the Mediterranean Diet, using the 14-point Mediterranean Diet Adherence Score (MEDAS). Adherence and related factors were measured. RESULTS AND CONCLUSIONS: Of a total of 922 respondents (664 women) mean aged 42.61 years (range 20-69), 61.2% showed a good adherence to the Mediterranean Diet. Adherence was significantly associated with the professional categories of physicians (OR = 1.92; 95% CI: 1.20-3.06; p = 0.01) and nurses (OR = 1.67; 95% CI: 1.08-2.57). Furthermore, it was associated with physical exercise (OR = 1.78; 95% CI: 1.29-2.47; p < 0.001) and cooking at home (OR = 1.35; 95% CI: 1.00-1.80; p = 0.05). However, adherence was not significantly associated with age or sex, comorbidities, working hours, alcohol, or tobacco consumption. Quantifying knowledge of the diet would be useful, as well as increasing educational programs, promoting physical exercise and cooking habits.

RESUMO

BACKGROUND: Infections caused by Candida are an emerging pathology on surgical wards. The aim of the present study was to evaluate the incidence, characteristics, and predictive factors of mortality in patients colonized and/or infected by Candida spp. in this setting. METHODS: A consecutive series of 105 patients hospitalized on a general surgery ward between 2000 and 2004 were included, and 118 positive cultures for Candida were identified. The variables age, sex, previous medical history, current disease, anemia, ICU stay, type and localization of the microorganism, need for parenteral nutrition, and transfusions were recorded. The primary outcome was in-hospital mortality. A univariate analysis was performed to determine which of these variables were associated with mortality. With a logistic regression model, independent prognostic factors of mortality were determined. RESULTS: The prevalence of patients colonized and/or infected by Candida on our surgical ward was 0.98% (CI 95%: 0.79-1.17), and the incidence was 49 cases per 1,000 patient-years. Of the 105 patients in this series, 56 were men (53%) and 49 women (47%); the mean age was 63.8 years (SD +/- 15.7). Twelve patients (11.4%) had candidemia. Crude mortality was 23% (24 patients), whereas the mortality attributable to candidemia was 25% (3/12 cases). Anemia (p = 0.001); transfusions (p = 0.003), and an ICU stay (p = 0.002) were associated with mortality. Candidemia was associated with neoplasms (p = 0.02) and the infection caused by Candida parapsilosis (p = 0.04). The only independent factor related to mortality was the anemia (p = 0.028; Odds Ratio: 6.43; 95% CI: 1.23-33.73). CONCLUSIONS: Colonization and/or infection by Candida spp. in non-ICU hospitalized surgical patients implies a relative high mortality. Anemia is an independent factor for mortality.

RESUMO

INTRODUCTION AND OBJECTIVES: Plasma c-reactive protein (crp) has been tested as a prognostic marker in acute heart failure (ahf). Whether its measurement really provides significant prognostic information when applied to elderly patients with ahf episodes remains unclear. METHODS: We measured the plasma crp values of patients admitted because of any type of ahf to internal medicine services. We evaluated the association of these values with the patients' baseline clinical characteristics and their 3-month posdischarge all-cause mortality or readmission rates. For comparison purposes, we divided the sample in tertiles of low, medium and high crp values (<2,24mg/l, 2,25-11,8mg/l and>11,8mg/l). RESULTS: We included 1443 patients with a median age of 80 years (interquartile range 73-85); 680 (47%) were men, with a moderate comorbid burden. 60.1% had preserved left ventricular ejection fraction (> 50%). Multivariate analysis confirmed an independent association between higher crp values and the presence of respiratory infection, lower systolic blood pressure and deteriorated renal function upon admission. Three months after the index admission, a total of 142 patients (9.8%) had died, and 268 (18.6%) had either been readmitted or died. admission crp values did not correlate with 3-month all-cause mortality (P=0.79), 3-month all-cause readmission (P=0.96) or the combination of both events (P=0.96). However, higher crp values were associated with a longer length of stay (P<0.001). CONCLUSION: Our study does not confirm an association between admission plasma crp values in elderly ahf patients and subsequent higher 3-month mortality or readmission risks.

RESUMO

OBJECTIVE: Several studies have reported that a higher degree of hemoconcentration in patients admitted for the treatment of acute heart failure (HF) constitutes a favorable prognostic factor in the year following the index episode. The objective of this study was to evaluate whether the highest degree of hemoconcentration at 3 months after admission for HF is also a prognostic factor for mortality and/or readmission in the 12 months after admission. PATIENTS AND METHOD: The hemoconcentration group was the upper quartile of the sample distributed according to hemoglobin increase at month 3 after discharge with respect to hemoglobin at the time of admission for HF in a multicenter prospective cohort of 1,659 subjects with HF. RESULTS: The mean follow-up until the first event was 294 days, and a total of 487 deaths and 1,125 readmissions were recorded. The hemoconcentration group had a lower risk of mortality or readmission for any cause (RR=0.75, 95% CI: 0.51-1.09 and RR=0.86, 95% CI: 0.70-1.05), although statistical significance was lost after multivariate analysis, while it was retained for other factors with recognized negative impact on the prognosis of patients with HF, such as age and functional class. CONCLUSIONS: The degree of hemoconcentration at 3 months after admission for HF is not prognostic of readmission or death in the subsequent year.

RESUMO

OBJECTIVES: To describe the predictors of hospital mortality in nonagenarian patients. PATIENTS AND METHOD: We retrospectively studied 421 patients aged 90 years or older hospitalised in a department of internal medicine. Using logistic regression, we analysed the association between demographic, clinical and functional parameters and hospital mortality. RESULTS: The mean age was 92.5 years (SD±2.5), and 265 (62.9%) of the patients were women. The main diagnoses were infectious diseases (257 patients, 61%) and heart failure (183, 43.5%), and the mean stay was 11.9 days (SD±8.6). During the hospitalisation, 96 patients died (22.8%). The predictors of mortality were age (P=.002), functional state (P=.006), comorbidity (P=.018) and diagnoses of pneumonia (P=.001), sepsis (P=.012) and respiratory failure (P<.001). CONCLUSION: The hospital mortality of nonagenarian patients treated in internal medicine exceeds 20% and is associated with pneumonia, comorbidity burden and functional impairment.

RESUMO

BACKGROUND/AIMS: Mesenteric venous thrombosis (MVT) is a rare condition with a challenging diagnosis. The aim of this study was to evaluate its association with systemic diseases and coagulation disorders. METHODOLOGY: Out of 132 patients operated on because of mesenteric ischemia between 1988 and 2002, all patients with a documented MVT were retrospectively recorded. Epidemiological and clinical data, complications and perioperative mortality were analyzed. RESULTS: Twenty-one patients, 10 male and 11 female, had MVT. Mean age was 63.8 years (SD: +/- 20.9). Arterial hypertension (57.1%) was the most prevalent associated condition. Other associated disorders were neoplasms (3 cases), liver cirrhosis (1 case), recurrent pulmonary thromboembolism (1 case), and one or more coagulation disorders (7 cases): lupus anticoagulant (2 cases); factor V Leiden (2 cases); protein S deficiency (3 cases); antithrombin III deficiency (1 case) and disseminated intravascular coagulation (1 case). Perioperative mortality was 33.3% (7 patients). Mean survival at the end of the study was 65.73 months (EE: 13.82). Patients with a coagulation disorder had a higher survival rate than those presenting without it (p = 0.02). CONCLUSIONS: MVT is still a lethal condition with a high morbidity that could be associated to systemic disorders and hypercoagulability syndromes in more than 50% of the cases.

RESUMO

Heart failure (HF) predominantly affects elderly individuals and has a significant impact on the health systems of developed countries. Comorbidities are present in most patients with HF by acting as the cause, the consequence or a mere coincidence. In addition to their high prevalence, they have considerable relevance because they can mask symptoms, impede the diagnosis and treatment, contribute to progression and negatively influence the prognosis of HF. Most of the associated comorbidities result in a greater number of hospitalisations, poorer quality of life and increased mortality. Given that many of these comorbidities are underdiagnosed, their detection could improve the outcome and quality of life of patients with HF. This article reviews the prevalence and prognostic meaning of the most prevalent comorbidities associated with HF.

RESUMO

HISTORY AND OBJECTIVES: To analyze the differential clinical characteristics according to gender of patients with heart failure in terms of etiology, comorbidity, triggers, treatment, hospital stay and overall mortality at one year. PATIENTS AND METHOD: We employed data from the RICA registry, a multicenter prospective cohort of patients hospitalized in internal medicine departments for heart failure, with a follow-up of one year. We analyzed the differences between the gender in terms of the etiology of the heart disease, comorbidity, triggers, left ventricle ejection fraction, functional state, mental condition, treatment, length of stay and mortality at 1 year. RESULTS: A total of 1772 patients (47.2% men) were included. The women were older than the men (p<.001) and had a higher prevalence of hypertension, obesity, chronic kidney disease, atrial fibrillation and preserved left ventricle ejection fraction (p<.001). The men's medical history had a predominance of myocardial infarction, chronic obstructive pulmonary disease, peripheral arteriopathy (p<.001) and anemia (p=.02). In the women, a hypertensive etiology was predominant, followed by valvular. The main triggers were hypertension and atrial fibrillation. Treatment with beta-blockers, ACEIs and/or ARBs did not differ by sex. The women had poorer functional capacity (p<.001), according to the Barthel index. After adjusting for age and other prognostic factors, the mortality at one year was lower among the women (RR: 0.69; 95% CI 0.53-0.89; p=.004). CONCLUSIONS: HF in women occurs at a later age and with different comorbidities. The hypertensive and valvular etiology is predominant, with preserved left ventricle ejection fraction, and the age-adjusted mortality is lower than in men.

RESUMO

The relationships between the number of Ito cells; serum N-terminal type III procollagen and laminin; clinical and biochemical parameters of liver function derangement; histomorphometrically assessed total amount of liver fibrosis; and daily ethanol intake were studied in 43 patients affected by chronic alcoholic liver disease (10 cirrhotics). Significant correlations were found between serum laminin and N-terminal type III procollagen and histological, clinical and biochemical data of liver function derangement, but no correlation was found between the aforementioned parameters and the percentage of Ito cells, which in turn seemed to be related to ethanol ingestion.

RESUMO

Peripheral and autonomic neuropathy has been evaluated, both by clinical and neurophysiological and by clinical methods, respectively, in 33 alcoholics, 20 of them cirrhotics. Nerve dysfunction was compared with liver function parameters, the Child-Pugh score, and parameters derived from ethanol consumption. Few relationships were obtained between the autonomic and peripheral nerve dysfunction, and between these and liver function impairment, although Pugh's score was higher when hyporeflexia and altered heart rate response to orthostatism were present. Thus, in the alcoholic, autonomic and peripheral neuropathy, seem to be dependent on each other, whereas there appears to be a weak correlation between liver function and both autonomic and peripheral neuropathy.

RESUMO

The aim of the present study is to analyse the relative and combined effects of ethanol and protein deficiency on serum testosterone and LH, and on gonadal histology, in ethanol fed rats. The study was performed in 32 animals divided into four groups, fed with the Lieber & DeCarli control, 36% ethanol, 2% protein, and 36% ethanol 2% protein containing diets, respectively. Two months later, rats were anaesthetized with pentobarbital and sacrificed, and the right testes and epididymus were carefully removed. Both ethanol and protein deficiency independently lead to a decrease in serum testosterone levels, and to testicular atrophy, lowest testosterone levels and highest degrees of atrophy being observed in the rats receiving the 36% ethanol, 2% protein containing diet. Both serum testosterone and testicular size and weight significantly correlated with final weight and serum albumin. Hypospermia, atrophy of the seminiferous tubules, and reduced epididymal diameter were also observed in this last group of animals. Thus, protein deficiency may contribute to hypogonadism of alcoholics.

RESUMO

The present study has been performed in order to establish the relative and combined roles of ethanol and malnutrition on liver Fe, Zn, Cu, and Mn alterations in alcoholic male adult Wistar rats, and also the relationships between these alterations and histomorphometrically determined hepatocyte and nuclear areas, perivenular fibrotic rim area, and total amount of fat present in the liver. Four groups of 8 animals each were fed: (1) a nutritionally adequate diet (C); (2) a 36% ethanol-containing (as percent of energy), isocaloric diet (A); (3) a 2% protein-containing, isocaloric diet (PD); and (4) a 36% ethanol, 2% protein-containing, isocaloric diet (A-PD), respectively, following the Lieber-DeCarli model. Ethanol-fed, protein-deficient animals showed the highest liver Fe, and the lowest Zn and Cu values, although differences in liver Zn, Mn, and Cu values were not significantly different between PD and A-PD groups. Statistically significant differences of these parameters were observed between the A and the A-PD groups, and between the A and PD groups, except for liver iron. Except for liver Mn, differences between C and A groups were statistically significant. These alterations correlated with liver fibrosis and steatosis, serum albumin, and weight loss, except for liver Mn, which was not correlated with fibrosis or steatosis. Thus, protein deficiency seems to enhance ethanol-induced liver Fe, Zn, and Cu alterations, whereas protein deficiency, but not ethanol, seems to play a major role on liver Mn alterations.

RESUMO

It is known that protein malnutrition conditions the development of liver steatosis, and may be accompanied by fibrosis. Ito cells intervene in the fibrogenesis, converting to transitional cells and myofibroblasts. Some trace elements, such as copper (Cu), iron (Fe) and manganese (Mn) act as co-factors, and zinc (Zn) acts as an inhibitor of a variety of enzymes involved in the collagen synthesis. This study analyzes the effects on the livers of 12 mate Wistar rats following two months administration of a hypoproteic (6%) isocaloric diet, comparing histomorphometric parameters (hepatocyte and nucleum area, total fat and fibrosis) and the liver content in Fe, Cu, Zn and Mn, with those in 12 control rats of similar age and sex. The experimental group revealed a significant reduction in hepatocyte nucleum area (p < 0.001), an increase in the ratio of hepatocyte cytoplasmatic and nucleum hepatocyte area, pronounced steatosis and slight fibrosis. No differences were found in Ito cell percentages. The experimental group showed a significant increase in liver content of Fe (p = 0.01) and a significant drop in Mn content (p < 0.01), Zn (p = 0.05) and Cu (p < 0.01). Liver iron content correlated significantly with total fat level (p = 0.03).
