RESUMO

AIMS: Hypertonic saline solution (HSS) plus intravenous (IV) loop diuretic appears to enhance the diuretic response in patients hospitalized for heart failure (HF). The efficacy and safety of this therapy in the ambulatory setting have not been evaluated. We aimed to describe the design and baseline characteristics of the SALT-HF trial participants. METHODS AND RESULTS: 'Efficacy of Saline Hypertonic Therapy in Ambulatory Patients with HF' (SALT-HF) trial was a multicenter, double-blinded, and randomized study involving ambulatory patients who experienced worsening heart failure (WHF) without criteria for hospitalization. Enrolled patients had to present at least two signs of volume overload, use ≥ 80 mg of oral furosemide daily, and have elevated natriuretic peptides. Patients were randomized 1:1 to treatment with a 1-h infusion of IV furosemide plus HSS (2.6-3.4% NaCl depending on plasmatic sodium levels) versus a 1-h infusion of IV furosemide at the same dose (125-250 mg, depending on basal loop diuretic dose). Clinical, laboratory, and imaging parameters were collected at baseline and after 7 days, and a telephone visit was planned after 30 days. The primary endpoint was 3-h diuresis after treatment started. Secondary endpoints included (a) 7-day changes in congestion data, (b) 7-day changes in kidney function and electrolytes, (c) 30-day clinical events (need of IV diuretic, HF hospitalization, cardiovascular mortality, all-cause mortality or HF-hospitalization). RESULTS: A total of 167 participants [median age, 81 years; interquartile range (IQR), 73-87, 30.5% females] were randomized across 13 sites between December 2020 and March 2023. Half of the participants (n = 82) had an ejection fraction >50%. Most patients showed a high burden of comorbidities, with a median Charlson index of 3 (IQR: 2-4). Common co-morbidities included diabetes mellitus (41%, n = 69), atrial fibrillation (80%, n = 134), and chronic kidney disease (64%, n = 107). Patients exhibited a poor functional NYHA class (69% presenting NYHA III) and several signs of congestion. The mean composite congestion score was 4.3 (standard deviation: 1.7). Ninety per cent of the patients (n = 151) presented oedema and jugular engorgement, and 71% (n = 118) showed lung B lines assessed by ultrasound. Median inferior vena cava diameter was 23 mm, (IQR: 21-25), and plasmatic levels of N-terminal-pro-B-type natriuretic peptide (NTproBNP) and antigen carbohydrate 125 (CA125) were increased (median NT-proBNP 4969 pg/mL, IQR: 2508-9328; median CA125 46 U/L, IQR: 20-114). CONCLUSIONS: SALT-HF trial randomized 167 ambulatory patients with WHF and will determine whether an infusion of hypertonic saline therapy plus furosemide increases diuresis and improves decongestion compared to equivalent furosemide administration alone.

RESUMO

BACKGROUND: There is an urgent need for highly efficacious antiviral therapies in immunosuppressed hosts who develop coronavirus disease (COVID-19), with special concern for those affected by hematological malignancies. CASE PRESENTATION: Here, we report the case of a 75-year-old male with chronic lymphocytic leukemia who was deficient in CD19+CD20+ B-lymphocyte populations due to previous treatment with anti-CD20 monoclonal antibodies. The patient presented with severe COVID-19 pneumonia due to prolonged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and was treated with two courses of the antiviral plitidepsin on a compassionate use basis. The patient subsequently achieved an undetectable viral load, and his pneumonia resolved. CONCLUSIONS: Treatment with plitidepsin was well-tolerated without any further hematological or cardiovascular toxicities. This case further supports plitidepsin as a potential antiviral drug in SARS-CoV-2 patients affected by immune deficiencies and hematological malignancies.

RESUMO

BACKGROUND AND OBJECTIVES: To date, in Spain, there are no studies that have evaluated the prevalence of hypertrophic cardiomyopathy in the general population. The aim of this study was to assess the prevalence of hypertrophic cardiomyopathy in a large sample of the working population of Spain. MATERIALS AND METHODS: The study included 13,179 workers (73% men; mean age: 40 years) from 5 regions of Spain who, between May 2008 and November 2010, had a medical examination with an electrocardiogram. The workers with suggestive abnormalities in the electrocardiogram or a predisposing medical history (exertional syncope or sudden death of a family member younger than 50 years) were referred for an echocardiographic evaluation. We defined hypertrophic cardiomyopathy as a parietal thickness ≥13mm in any segment of the left ventricle. We estimated the prevalence of hypertrophic cardiomyopathy in the entire sample and in the workers without hypertension. RESULTS: A total of 1008 workers were selected for the echocardiogram, although only 496 (49.2% of those selected) of these attended the appointment. After the echocardiogram, we detected 16 cases of hypertrophic cardiomyopathy, estimating a prevalence of 0.24% for the entire sample. In the subgroup of workers with no hypertension, we observed 10 cases of hypertrophic cardiomyopathy, which corresponds to an estimated prevalence of 0.19%. CONCLUSIONS: In our sample of the working population in Spain, the estimated prevalence of hypertrophic cardiomyopathy was 0.24%. In the subgroup of patients with no hypertension, the estimated prevalence was 0.19%.

RESUMO

PURPOSE: The aim of the current survey was to describe the functioning of cardio-oncology (C-O) units in Spain. METHODS: All members of the Spanish Society of Cardiology pertaining to scientific communities related to C-O received questionnaires on the existence of specific programs at their institutions. A second, more extensive questionnaire was sent to the centers which reported C-O organization. RESULTS: We identified 56 centers with C-O programs of which 32 (62.5%) replied to the extended questionnaire. 28% of all centers reported having a multidisciplinary unit involving specialists in several areas. More than 80% of the centers developed surveillance protocols locally adapted which included advanced echocardiographic techniques (68%) or troponin (82%). CONCLUSIONS: The number of institutions with C-O programs is still limited but higher than reported in a survey in 2017. Development of multidisciplinary units of C-O should be promoted to improve the cardiovascular health of cancer patients.

RESUMO

BACKGROUND: Horizontal equity in access to public general practitioner (GP) services by socioeconomic group has been addressed econometrically by testing the statement "equal probability of using public GP services for equal health care needs, regardless of socioeconomic status". Based on survey data, the conventional approach has been to estimate binomial econometric models in which when the respondent reports having visited a public GP, it counts as 1, otherwise it counts as 0. This is what we call a compartmentalised approach. Those respondents who did not visit a public GP but visited instead another doctor (specialist or private GP) would count as 0 (despite having used instead other modes of health care), thus conclusions of the compartmentalised approach might be biased. In such cases, a multinomial econometric model -that we called comprehensive approach- would be more appropriate to analyse horizontal equity in access to public GP services. The objective of this paper is to test for this potential bias by comparing a compartmentalised and a comprehensive approach, when analysing horizontal equity in access to public GP. METHODS: Using data from the 2016/17 Spanish National Health Survey, we estimate the probability of visiting a public GP as determined by socioeconomic status, health care need and demographic characteristics. We use binomial and multinomial logit and probit models in order to highlight the potential differences in the conclusions regarding socioeconomic inequities in access to public GP services. Socioeconomic status is proxied by education level, social class and employment situation. RESULTS: Our results show that conclusions are sensitive to the approach selected. Particularly, the horizontal inequity favouring individuals with lower education that resulted from the compartmentalised approach disappears under a comprehensive approach and only a social class effect remains. CONCLUSION: An analysis of horizontal equity in access to a particular health care service (like public GP services) undertaken following a compartmentalised approach should be compared with a comprehensive approach in order to test that there is no bias as a consequence of considering as zeros the utilisation of other types of health care.

RESUMO

Medical assistance in dying (maid) is a new medical service in Canada. Access to maid for patients with advanced cancer can be daunting during periods of declining health near the end of life. In this report, we describe a collaborative approach between the centralized coordination service and a regional cancer centre as an effective strategy for enabling interdisciplinary care delivery and enhancing patient-centred care at the end of the patient's cancer journey.

RESUMO

INTRODUCTION: The COPD-LUCSS-DLCO score had been validated as a predictive tool capable of identifying patients with chronic obstructive pulmonary disease (COPD) and a high mortality risk associated with lung cancer (LC); however, studies have not been conducted yet on its use in standard clinical practice. The aim of this study was to estimate the COPD-LUCSS-DLCO scores for patients with COPD treated in Pulmonology consultations and to determine the incidence of LC in each of the subgroups. MATERIAL AND METHODS: A retrospective observational study was conducted with a cohort of 159 patients with COPD in Pulmonology outpatient follow-up consultations. We calculated the COPD-LUCSS-DLCO score (0-8) for each patient, with low risk considered at 0-3 points and high risk at ≥3.5 points. We calculated the incidence rate of LC in each of the subgroups. RESULTS: Sixty-two percent of the patients had a high-risk score. We estimated an overall LC rate of 30 per 1000 patients with COPD-year (95% CI: 16-53), 44 per 1000 patients with COPD-year (95% CI: 18-76) among those categorised as high risk and 17 per 1000 patients with COPD-year among those categorised as low risk (95% CI: 4-50). CONCLUSIONS: The use of the COPD-LUCSS-DLCO score in standard clinical practice could help detect patients with a greater risk of developing LC, which could help to better manage cases in an LC screening programme.

RESUMO

Entre enero y junio de 2014 se condujo una investigación en la región central de Venezuela con la finalidad de determinar la prevalencia del enterococcidio Cystoisospora suis en granjas porcinas intensivas. Para la determinación parasitaria se seleccionaron 572 camadas con signos de diarrea, así como 1.712 muestras fecales de cerdos adultos. Todas las muestras se cultivaron en dicromato de potasio al 2,5% y posteriormente se procesaron mediante una técnica coproparasitológica. Los resultados señalan que C. suis se encontró en 55 granjas (82,1%) y 210 camadas (36,7%), con los mayores valores de prevalencia en las dos primeras semanas de vida (P < 0,05). Al referir los resultados en cerdos adultos se encontró correlación significativa (rho = 0,35; P < 0,05) entre excreción de ooquistes en lechones y madres, lo que sugiere que cerdas madres podrían actuar como fuentes de infección. Se encontró correlación entre el número de partos de la cerda y los valores de prevalencia en camadas y cerdas lactantes (P < 0,05) lo que indica que, a mayor número de partos, disminuye la prevalencia. Probablemente estos hallazgos se asocian con mecanismos inmunológicos desconocidos. Se concluye que C. suis se encuentra ampliamente distribuido en Venezuela y que el enterococcidio puede ser controlado mejorando las condiciones higiénicas de las granjas; sin embargo, hay mecanismos inmunológicos aún sin dilucidar que podrían incidir en la cadena de transmisión del protozoario.


It was carried out an investigation at the central region of Venezuela from January to June 2014 with the aim to determine the prevalence of coccidian Cystoisospora suis in intensive swine herds. For parasitic determination 572 litters were selected with signs of diarrhea. Likewise, 1.712 fecal samples were also collected in mature pigs. Stool samples were cultured in a 2.5% potassium dichromate solution and later processed by coprological technique. The results of this investigation indicated that C. suis was observed in 55 herds (82.1%) and 210 litters (36.7%) with the highest prevalence values in first two weeks of age (P < 0.05). Regarding to mature pigs, there was a significant correlation (rho = 0.35; P < 0.05) among oocysts excretion in piglets and sows, suggesting that sows may act as infection sources. Sows parity was statistically correlated with the prevalence values in litters as in lactating sows (P < 0.05). This might indicate that as parity increase, prevalence decreases in these groups. Probably these findings are associated with unknown immunologic mechanisms. It is concluding that C. suis is broadly distributed in Venezuela and it could be controlled by improving conditions sanitary herd, however, non elucidated immunologic mechanisms might be involved in the protozoa transmission cycle.

RESUMO

INTRODUCTION: The aim of this study was to understand the prevalence of comorbidities and the usefulness of the PROFUND index for the prognostic stratification of patients with comorbidities in a hospital cardiology unit. PATIENTS AND METHODS: We consecutively analysed all patients hospitalized in 2012 in the department of cardiology. We recorded the comorbidities, length of stay, hospital mortality, Charlson indices and PROFUND indices. In the patients with comorbidities, we also recorded the readmissions and mortality during a 1-year follow-up. RESULTS: The study included 1,033 patients (mean age, 67±13.1 years; 35% women), 381 (36.9%) of whom had comorbidities, with a mean Charlson index of 6.4±1.7 and a mean PROFUND index of 2.5±2.5. Compared with the other patients, the patients with comorbidities were older (72 vs. 64 years, p<.001), had a higher mortality rate (2.9% vs. 1.1%, p=.046) and longer hospital stays (8±5.5 vs. 6±5.7 days, p<.001) and were more often admitted for heart failure (42.3% vs. 15.8%, p<.001). The PROFUND index was independently associated with overall mortality (hazard ratio [HR], 1.13; 95% CI: 1.01-1.27; p=.034) and with the presence of major adverse events during the 12-month follow-up (HR, 1.09; 95% CI: 1.01-1.18; p=.026). CONCLUSIONS: A high percentage of patients hospitalized in the department of cardiology had comorbidities. These patients had a higher prevalence of cardiovascular risk factors, longer stays and greater hospital mortality. The PROFUND index independently predicted mortality and adverse events during the follow-up.

RESUMO

Iron deficiency in patients with heart failure is a medical problem of recent particular interest. This interest has resulted from the publication of several clinical trials that demonstrated that the administration of intravenous iron to such patients improved their functional capacity and even reduced the number of hospitalisations for heart failure decompensation. However, applying the evidence from these studies in clinical practice is still controversial, both in terms of the diagnostic criteria for iron deficiency (absolute and functional) and the optimal method for iron replenishment. This article is a consensus document that integrates the recommendations of the Spanish Society of Internal Medicine and the Spanish Society of Cardiology. The article reviews the scientific evidence and proposes a diagnostic and therapeutic performance protocol for iron deficiency in heart failure.

RESUMO

The objective of this study was to validate the use of exogenous gonadotropin (PG600) treatment for stimulating estrus in noncyclic gilts and to compare lifetime productivity of gilts recorded as having natural (NAT) versus PG600-induced (PG600) first estrus in a commercial setting. Prepubertal Camborough gilts ( = 4,489) were delivered to a gilt development unit (GDU) with the goal of delivering known cyclic breeding-eligible females to the sow farm (SF). A boar exposure area (BEAR) was designed to facilitate stimulation and detection of puberty by providing fence line and direct contact (15 min daily) with mature boars over an intensive 28-d period, starting at approximately d 160 (d 0). At d 14, nonpubertal gilts were mixed in new pen groups. At d 23, noncyclic "opportunity" gilts with no record of vulval development and required to meet breeding targets, were eligible for treatment with PG600 to induce puberty. Overall, 77.6% ( = 3,475) of gilts exhibited standing estrus (NAT = 2,654; PG600 = 821) and were eligible for shipping to the SF at approximately 35 d, and 76.6% of gilts that were administered PG600 exhibited the standing reflex within 13 d of treatment. Ultimately, 72.0% of gilts entering the GDU were delivered to the SF as breeding-eligible females. Considering the gilts delivered, a greater proportion of NAT than PG600 gilts were successfully bred ( < 0.001) and had better farrowing rates to first service, and overall farrowing rates (including gilts that returned to estrus and were rebred) were greater for NAT compared to PG600 gilts ( < 0.001) . Farrowing rates at second and third parity were similar between NAT and PG600 gilts; however, at fourth parity, a greater proportion of NAT gilts farrowed. In comparison, considering only gilts served, there was no difference ( > 0.05) in the proportion of NAT and PG600 gilts farrowing a third litter, but a greater proportion of NAT than PG600 gilts farrowed their fourth litter ( < 0.001). There was no difference between NAT and PG600 gilts for litter size at parity 1 through 4 or total pigs born over 4 parities ( > 0.05). A negative correlation ( < 0.0001) was detected between age at puberty and lifetime growth rate at puberty, and growth rate classification affected age and weight at puberty. However, retention rates and total sow productivity to parity 4 were not affected by growth rate classification at puberty.

RESUMO

UNLABELLED: Down syndrome is the most frequent aneuploidy in live births, with an overall frequency of 1/600-700 births. The overexpression of cystathionine ß-synthase is thought to participate in the presentation of some phenotypes observed in Down syndrome. OBJECTIVE: The aim of this study was to compare the expression levels of cystathionine ß-synthase and histopathological observations from placentas of infants with Down syndrome and healthy newborns. MATERIALS AND METHODS: Six placentas of fetuses/infants with Down syndrome and sixteen placentas of healthy fetuses were studied. Cystathionine ß-synthase mRNA and protein expression were performed by real-time PCR and immunohistochemistry, respectively. RESULTS: We observed an increase in cystathionine ß-synthase mRNA expression (p = 0.0465) and protein levels (p = 0.009) in placentas of fetus/infants with Down syndrome compared with controls. Significantly more circinate edges (p = 0.0007) and trophoblast inclusions (p = 0.0037) were observed in the group with Down syndrome compared with control group. CONCLUSION: The results demonstrate overexpression of cystathionine ß-synthase mRNA and protein in placentas of fetuses/infants with trisomy 21. Further histological abnormalities were found in placentas of patients with Down syndrome, suggesting an alteration in the development of placenta.

RESUMO

There is scarce information about the impact of antiviral treatment on subsequent progression of liver fibrosis in HIV-infected patients with chronic hepatitis C who experience different outcomes following peginterferon-ribavirin therapy. We conducted a retrospective study of a cohort of HIV/HCV-coinfected patients with longitudinal assessment of liver fibrosis using elastometry. Patients were split out into four groups according to the prior peginterferon-ribavirin response: sustained virological response (SVR), relapse (R), partial response (PR) and null response (NR). A group of untreated, coinfected patients was taken as control. Significant liver fibrosis progression (sLFP) was defined as a shift from baseline Metavir estimates ≤ F2 to F3-F4, or by >30% increase in liver stiffness in patients with baseline F3-F4. Conversely, significant liver fibrosis regression (sLFR) was defined as a shift from baseline Metavir estimates F3-F4 to ≤ F2, or by >30% reduction in liver stiffness in patients that kept on F3-F4. A total of 498 HIV/HCV-coinfected patients were examined. They were classified as follows: 138 (27.7%) SVR, 40 (8%) R, 61 (12.2%) PR, 71 (14.3%) NR and 188 (37.8%) naive. After a mean follow-up of 53.3 months, sLFP occurred less frequently in patients with SVR (7.2%) compared with R (25%; P = 0.002), PR (23%; P = 0.002), NR (29.6%; P < 0.001) and naïve (19.7%; P = 0.002). Conversely, sLFR was 26.1% in SVR compared with 10% in R (P = 0.03), 14.8% in PR (P = 0.06), 16.9% in NR (P = 0.07) and 10.6% in naïve (P < 0.001). Sustained clearance of serum HCV-RNA following a course of antiviral treatment is the major determinant of liver fibrosis regression in HIV/HCV-coinfected patients.

RESUMO

BACKGROUND: To evaluate and compare the ability of two Fourier-domain optical coherence tomography (OCT) devices to detect retinal and retinal nerve fibre layer (RNFL) atrophy in patients with Alzheimer's disease (AD) compared with healthy subjects; to test the intra-session reliability of two OCT devices in AD patients and healthy subjects. METHODS: AD patients (n=75) and age-matched healthy subjects (n=75) underwent three Macular Cube 200 × 200 protocols using the Cirrus and Spectralis OCT devices and three 360° circular scans centred on the optic disc using the Cirrus OCT device, the classic glaucoma application, and the new Nsite Axonal Analytics application of the Spectralis OCT instrument. Differences between healthy and AD eyes were compared, and measurements provided by each OCT protocol were compared. Reliability was measured using intraclass correlation coefficients and coefficients of variation. Correlations between OCT measurements and disease duration and severity were also analysed. RESULTS: Retinal thinning was observed in AD eyes in all areas except the fovea using both OCT devices. RNFL atrophy was detected in AD eyes with all three protocols, but the Nsite Axonal application was the most sensitive. Measurements by the two OCT devices were correlated, but differed significantly. Reliability was good using all protocols, but better with the glaucoma application of Spectralis. Mean RNFL thickness provided by the Nsite Axonal application correlated with disease duration. CONCLUSIONS: Fourier-domain OCT is a valid and reliable technique for detecting subclinical RNFL and retinal atrophy in AD, especially using the Nsite Axonal application. RNFL thickness decreased with disease duration.

RESUMO

BACKGROUND: Diabetic patients undergoing percutaneous coronary intervention (PCI) have a worse prognosis than non-diabetic patients. The anti-oxidized LDL antibodies (anti-LDLox ab) have recently been suggested to be protective against the development of diabetes. The aim of this study was to compare the levels of IgG and IgM anti-oxidized LDL antibodies with reference to the new diagnostic criteria for carbohydrate metabolism disorders after an oral glucose tolerance test (OGTT) in hospitalized patients scheduled to undergo percutaneous coronary intervention. METHODS: We undertook a cross-sectional study of 110 patients undergoing PCI. The patients were classified as being normal (oral glucose test tolerance normal, OGTT-N), or having impaired glucose tolerance (IGT) or type 2 diabetes mellitus (T2DM) according to their glucose levels at baseline and after an OGTT. RESULTS: An inverse slope was found in the levels of IgG anti-oxidized LDL antibodies between the OGTT-N patients (optical density (OD) = 0.109) and the patients with IGT (OD = 0.099) or T2DM (OD = 0.084) (p = 0.019). An inverse correlation was also detected between the levels of IgG anti-oxidized LDL antibodies and baseline glycemia (r = -0.23, p = 0.018). CONCLUSIONS: Patients with coronary disease and carbohydrate metabolism disorders have much lower levels of IgG anti-oxidized LDL antibodies than normoglycemic patients.

RESUMO

Coronary Artery Diseases (CAD) is the first mortality cause in industrialized countries. The possibility of regenerating myocardium injured tissue using the cell therapy is a promising option to regenerate cardiac tissue. Currently, a variety of adult stem/ progenitor cells are undergoing clinical evaluation, but it is very important to study and characterize the bone marrow-derived progenitor/ stem cells, the main source of cells used for human cardiac repair, before their clinical use. Bone marrow-derived endothelial progenitor cells (EPC) home sites of ischemia and differentiate into endothelial cells, increase the neovascularization of ischemic tissue. Moreover recently, it has been observed that EPC can be able to differentiate or transdifferentiate to like-adult cells resident in cardiac tissues. The characterization of phenotype EPC is complex, because express hematopoietic stem cells (CD133 and/or CD34) and endothelial markers such as vascular endothelial growth factor receptor 2 (KDR). Several studies described subpopulation of EPC expressing CD34+D133+KDR+ phenotype in literature, but some other authors suggest other phenotype. The EPC capacity of mobilization or recruitment/ homing to ischemic tissue areas by cytokines are reviewed. Finally are described clinical studies in CAD using bone marrow-derived progenitor cells permitting human cardiac tissue repair.

RESUMO

OBJECTIVE: To study the prevalence of Mycobacterium tuberculosis infection (MTBI) and past/current tuberculosis (TB) among human immunodeficiency virus (HIV) infected persons in Spain. DESIGN: Longitudinal study conducted between 2000 and 2003 at 10 HIV hospital-based clinics. Data were drawn from clinical records. Associations were measured using odds ratios (ORs) and their 95% confidence intervals (95%CI). RESULTS: Of the 1242 persons who met the eligibility criteria, most were male (75%), aged <40 years (75%) and unemployed (40%). HIV infection occurred through intravenous drug use (53%), heterosexual sex (29%) and sex between men (16%). In the initial evaluation, 315 subjects had evidence of MTBI: 84 (6.8%) had a history of TB, 23 (1.8%) current TB and 208 (16.8%) latent tuberculosis infection (LTBI). MTBI was associated with male sex, age 30-49 years, contact with a TB case, homelessness, poor education, and negatively with CD4 <100 cells/mm(3). Among subjects with MTBI, past/current TB was associated with retirement/disability (OR 6, 95%CI 1.6-22.5), CD4 <200 cells/mm(3) (OR 9.7, 95%CI 3.8-24.6), viral load >55,000 copies (OR 5.3, 95%CI 1.4-20.0), and negatively, with skilled work (OR 0.4, 95%CI 0.1-1.0) or administrative/managerial/professional work (OR 0.05, 95%CI 0.01-0.4). CONCLUSION: Social context has an impact on the effectiveness of HIV and TB control programmes even in industrialised countries with free access to health care.

RESUMO

BACKGROUND AND OBJECTIVES: The cost of hospitalization represents the greatest proportion of total expenditure due to heart failure. Our objective was to analyze the trends of morbidity of chronic heart failure in Andalusia between 1990-2000. MATERIAL AND METHODS: The data on hospitalizations in Andalusia (title 428 of the ninth revision of the International Disease Classification) were obtained from the National Survey of Hospital Morbidity of the National Institute of Statistics. The rates, standardized by age and gender, of admission due to heart failure were calculated by the direct standardization method. RESULTS: The absolute number of hospitalizations due to hear failure in people over 45 years was 4,345 in 1990 and 10,153 in 2000 (a relative increase of 230%) and it represents 14.2% hospitalizations in Spain. The increase was focused on those over 65 years and the standardized rates were slightly greater in women than in men. CONCLUSIONS: Hospitalization discharge rates increased mostly in the population older than 65 and women showed hospitalization rates slightly greater than men.
