RESUMO

INTRODUCTION: Heart failure (HF) is one of the leading causes of morbidity and mortality worldwide. This study aimed to assess the impact of sex on sociodemographic, clinical, and laboratory parameters in patients with HF who were included in the Colombian Heart Failure Registry (RECOLFACA). METHODS: This was a cross-sectional analytical research. All 2528 patients included in RECOLFACA were analysed. The Mann-Whitney U test was used to compare median values as well as first and third quartiles (Q1-Q3). The age-related trend of NT-proBNP levels for both men and women groups was statistically evaluated. RESULTS: The study included 2528 patients with HF (1072 women and 1456 men). The echocardiographic evidence showed that men presented reduced left ventricular ejection fraction (LVEF) (79.63 vs. 69.75%, respectively; p < 0.001) more often than women, which had a significantly higher proportion of preserved LVEF (20.46 vs.11.24%, respectively; p < 0.001). Women displayed a higher value of systolic blood pressure (p < 0.001) and heart rate (p = 0.014) compared to men. Haemoglobin, creatinine, and sodium levels were significantly higher in men. Men had a considerably lower glomerular filtration rate value, with the median reaching a G3a value for chronic renal failure. According to age, the levels of NT-proBNP in each sex increased equivalently with age. CONCLUSION: Sex differences presented in this study are comparable to those discovered in other nations. However, certain variations show that these sex differences may differ by geographical area, which should encourage further investigations to describe them.

RESUMO

Background: The value of Sodium-glucose cotransporter-2 inhibitors (SGLT-2 inhibitor) therapy in individuals with heart failure with preserved EF (HFpEF) was unknown until the EMPEROR-Preserved trial. We aimed to assess the proportion of patients with HFpEF that are eligible for empagliflozin therapy within the Colombian Heart Failure Registry (RECOLFACA). Methods: RECOLFACA enrolled adult patients with a HF diagnosis during 2017-2019 from 60 medical centers in Colombia. Criteria of the EMPEROR-Preserved Trial were used to recruit participants. The main outcome was individual eligibility with N-terminal pro-B-type natriuretic peptide (NT-proBNP) criteria, while the secondary outcome was eligibility without NT-proBNP data. Results: RECOLFACA had 799 patients with HFpEF (mean age70.7 ± 13.5; 50.7 % males). According to the major selection criteria of the EMPEROR Preserved Trial, 73.7 % patients would be eligible for empagliflozin therapy initiation when considering the NT-proBNP threshold. The NT-proBNP threshold represented the main determinant of ineligibility in patients with this biomarker measure (13.6 %; n = 16). In patients without NT-proBNP data, the main reasons for exclusion were the diagnosis of symptomatic hypotension or a systolic blood pressure below 100 mmHg (7.5 %), having an eGFR < 20 ml/min/1.73 m2 (4.3 %), and haemoglobin < 9 g/dl (3.1 %). Excluding NT-proBNP criteria increased empagliflozin eligibility to 80.6 %. Conclusion: Most patients with HFpEF from RECOLFACA are potential candidates for empagliflozin therapy initiation according to the EMPEROR-Preserved trial criteria. These findings favor the utilization of SGLT-2 inhibitor medications in daily medical practice, which may further decrease morbidity and mortality in HF patients, regardless of their EF classification.

RESUMO

INTRODUCTION: Heart failure and type 2 diabetes mellitus are critical public health issues. OBJECTIVE: To characterize the risk factors for mortality in patients with heart failure and type 2 diabetes mellitus from a large registry in Colombia and to evaluate the potential effect modifications by type 2 diabetes mellitus over other risk factors. MATERIALS AND METHODS: Heart failure patients with and without type 2 diabetes mellitus enrolled in the Registro Colombiano de Falla Cardíaca (RECOLFACA) were included. RECOLFACA enrolled adult patients with heart failure diagnosis from 60 medical centers in Colombia during 2017-2019. The primary outcome was all-cause mortality. Survival analysis was performed using adjusted Cox proportional hazard models. RESULTS: A total of 2514 patients were included, and the prevalence of type 2 diabetes mellitus was 24.7% (n = 620). We found seven independent predictors of short-term mortality for the general cohort, chronic obstructive pulmonary disease, sinus rhythm, triple therapy, nitrates use, statins use, anemia, and hyperkalemia. In the type 2 diabetes mellitus group, only the left ventricle diastolic diameter was an independent mortality predictor (HR = 0.96; 95% CI: 0.93-0.98). There was no evidence of effect modification by type 2 diabetes mellitus on the relationship between any independent predictors and all-cause mortality. However, a significant effect modification by type 2 diabetes mellitus between smoking and mortality was observed. CONCLUSIONS: Patients with type 2 diabetes mellitus had higher mortality risk. Our results also suggest that type 2 diabetes mellitus diagnosis does not modify the effect of the independent risk factors for mortality in heart failure evaluated. However, type 2 diabetes mellitus significantly modify the risk relation between mortality and smoking in patients with heart failure.

Introducción. La insuficiencia cardíaca y la diabetes mellitus de tipo 2 son problemas críticos de salud pública. Objetivo. Caracterizar los factores de riesgo de mortalidad en pacientes con insuficiencia cardíaca y la diabetes mellitus de tipo 2 de un registro grande en Colombia y evaluar las posibles modificaciones del efecto de la diabetes mellitus de tipo 2 sobre otros factores de riesgo. Materiales y métodos. Se incluyeron pacientes con insuficiencia cardíaca con y sin diabetes mellitus de tipo 2, inscritos en el Registro Colombiano de Insuficiencia Cardíaca (RECOLFACA). RECOLFACA incorporó pacientes adultos con diagnóstico de insuficiencia cardíaca de 60 centros médicos de Colombia durante 2017-2019. El resultado primario fue la mortalidad por todas las causas. El análisis de supervivencia se realizó utilizando modelos ajustados de riesgos proporcionales de Cox. Resultados. Se incluyeron 2.514 pacientes, la prevalencia de diabetes mellitus de tipo 2 fue del 24,7 % (n = 620). Encontramos siete predictores independientes de mortalidad a corto plazo para la enfermedad pulmonar obstructiva crónica del grupo sin diabetes mellitus de tipo 2, el ritmo sinusal, la terapia triple, el uso de nitratos, el uso de estatinas, la anemia y la hiperpotasemia. En el grupo de diabetes mellitus de tipo 2, solo el diámetro diastólico del ventrículo izquierdo fue un predictor de mortalidad independiente (HR = 0,96; IC95 %: 0,93 - 0,98). No hubo evidencia de modificación del efecto de la diabetes mellitus de tipo 2 sobre la relación entre ningún predictor independiente y la mortalidad por todas las causas. Sin embargo, se observó una modificación significativa del efecto de la diabetes mellitus de tipo 2 entre el tabaquismo y la mortalidad. Conclusiones. Los pacientes con diabetes mellitus de tipo 2 tuvieron mayor riesgo de mortalidad. Los resultados también sugieren que el diagnóstico de diabetes mellitus de tipo 2 no modifica el efecto de los factores de riesgo independientes de mortalidad en IC evaluados. Sin embargo, la diabetes mellitus de tipo 2 modifica significativamente la relación de riesgo entre mortalidad y tabaquismo en pacientes con insuficiencia cardíaca, posiblemente debido a un efecto sinérgico negativo que resulta en lesión vascular.

RESUMO

OBJECTIVES: This post hoc analysis of SODIUM-HF (Study of Dietary Intervention under 100 mmol in Heart Failure) assessed the association between baseline dietary sodium intake and change at 6 months with a composite of cardiovascular (CV) hospitalizations, emergency department visits and all-cause death at 12 and 24 months. BACKGROUND: Dietary sodium restriction is common advice for patients with heart failure (HF). Randomized clinical trials have not shown a beneficial effect of dietary sodium restriction on clinical outcomes. METHODS: A multivariable Cox proportional hazard regression model was used to assess the association of dietary sodium intake measured at randomization with primary and secondary endpoints. RESULTS: The study included 792 participants. Baseline sodium intake was ≤ 1500 mg/day in 19.9% (n = 158), 1501-3000 mg/day in 56.5% (n = 448) and > 3000 mg/day in 23.4% (n = 186) of participants. The factors associated with higher baseline sodium intake were higher calorie consumption, higher body mass index and recruitment from Canada. Multivariable analyses showed no association between baseline sodium intake nor magnitude of 6-month change or 12- or 24-month outcomes. In a responder analysis, participants achieving a sodium intake < 1500 mg at 6 months showed an association with a decreased risk for the composite outcome (adjusted HR 0.52 [95% CI 0.25, 1.07] P = 0.08) and CV hospitalization (adjusted HR 0.51 [95% CI 0.24, 1.09] P = 0.08) at 12 months. CONCLUSION: There was no association between dietary sodium intake and clinical outcomes over 24 months in patients with HF. Responder analyses suggest the need for further investigation of the effects of sodium reduction in those who achieve the targeted dietary sodium-reduction level.

RESUMO

Background: Heart failure (HF) and atrial fibrillation (AF) represent conditions that commonly coexist. The impact of AF in HF has yet to be well studied in Latin America. This study aimed to characterize the sociodemographic and clinical features, along with patients' outcomes with AF and HF from the Colombian Heart Failure Registry (RECOLFACA). Methods: Patients with ambulatory HF and AF were included in RECOLFACA, mainly with persistent or permanent AF. A 6-month follow-up was performed. Primary outcome was all-cause mortality. To assess the impact of AF on mortality, we used a logistic regression model. A P value of < 0.05 was considered significant. All statistical tests were two-tailed. Results: Of 2,528 patients with HF in the registry, 2,514 records included information regarding AF diagnosis. Five hundred sixty (22.3%) were in AF (mean age 73 ± 11, 56% men), while 1,954 had no AF (mean age 66 ± 14 years, 58% men). Patients with AF were significantly older and had a different profile of comorbidities and implanted devices compared to non-AF patients. Moreover, AF diagnosis was associated with lower quality of life score (EuroQol-5D), mainly in mobility, personal care, and daily activity. AF was prevalent in patients with preserved ejection fraction (EF), while no significant differences in N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels were observed. Although higher mortality was observed in the AF group compared to individuals without AF (8.9% vs. 6.1%, respectively; P = 0.016), this association lost statistical significance after adjusting by age in a multivariate regression model (odds ratio (OR): 1.35; 95% confidence interval (CI): 0.95 - 1.92). Conclusions: AF is more prevalent in HF patients with higher EF, lower quality of life and different clinical profiles. Similar HF severity and non-independent association with mortality were observed in our cohort. These results emphasize the need for an improved understanding of the AF and HF coexistence phenomenon.

RESUMO

INTRODUCTION: Although several guidelines recommend that patients with heart failure with reduced ejection fraction (HFrEF) be treated with angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEIs/ARBs) or angiotensin receptor-neprilysin inhibitors (ARNIs), beta-blockers, mineralocorticoid receptor antagonists (MRAs), and sodium-glucose cotransporter-2 inhibitor (SGLT2i), there are still several gaps in their prescription and dosage in Colombia. This study aimed to describe the use patterns of HFrEF treatments in the Colombian Heart Failure Registry (RECOLFACA). METHODS: Patients with HFrEF enrolled in RECOLFACA during 2017-2019 were included. Heart failure (HF) medication prescription and daily dose were assessed using absolute numbers and proportions. Therapeutic schemes of patients treated by internal medicine specialists were compared with those treated by cardiologists. RESULTS: Out of 2,528 patients in the registry, 1,384 (54.7%) had HFrEF. Among those individuals, 88.9% were prescribed beta-blockers, 72.3% with ACEI/ARBs, 67.9% with MRAs, and 13.1% with ARNIs. Moreover, less than a third of the total patients reached the target doses recommended by the European HF guidelines. No significant differences in the therapeutic schemes or target doses were observed between patients treated by internal medicine specialists or cardiologists. CONCLUSION: Prescription rates and target dose achievement are suboptimal in Colombia. Nevertheless, RECOLFACA had one of the highest prescription rates of beta-blockers and MRAs compared to some of the most recent HF registries. However, ARNIs remain underprescribed. Continuous registry updates can improve the identification of patients suitable for ARNI and SGLT2i therapy to promote their use in clinical practice.

RESUMO

INTRODUCTION: Arterial hypertension represents one of the main comorbidities observed in patients with heart failure (HF) and one of the main risk factors for its development. Despite this, studies assessing this hypertensive etiology are scarce in Latin America. Our objective was to analyze the prevalence of HF of hypertensive etiology and evaluate its prognosis in patients enrolled in the Colombian Heart Failure Registry (RECOLFACA by its Spanish acronym). METHODS: RECOLFACA recruited adult patients diagnosed with HF in 60 centers in Colombia between 2017 and 2019. The primary outcome was all-cause mortality. A Cox proportional hazards regression model was used to assess factors associated with primary outcomes in patients with hypertensive HF. A p value <0.05 was considered significant. All statistical tests were two-tailed. RESULTS: Out of the total number of patients evaluated in RECOLFACA (n = 2,514), 804 had a diagnosis of HF with hypertensive etiology (31.9%). These patients were less frequently males and had a significantly older age and lower prevalence of comorbidities than those with HF of other etiologies. Additionally, patients with hypertensive HF had a higher prevalence of HF with preserved ejection fraction (HFpEF) (34.1% vs. 28.3%; p = 0.004). Finally, type 2 diabetes mellitus, chronic obstructive pulmonary disease diagnosis, and NYHA class IV were classified as independent mortality risk factors. CONCLUSIONS: Hypertensive HF represents about one-third of the total number of patients with HF in RECOLFACA. Compared with HF of other etiologies, it presents a differential clinical profile - older age and a higher prevalence of HFpEF. RECOLFACA has become a useful tool to characterize patients with HF in Colombia, with which it has been possible to carry out a more specific search and reach the diagnosis of this pathology in our population, and it has served as an example to stimulate registries of patients with HF in other countries in the region.

RESUMO

The field of heart failure has evolved in terms of the therapies that are available including pharmaceutical and device therapies. There is now substantial randomized trial data to indicate that dietary sodium restriction does not provide the reduction in clinical events with accepted heterogeneity in the clinical trial results. Dietary sodium restriction should be considered for some but not all patients and with different objectives than clinical outcomes but instead for potential quality of life benefit. In addition, fluid restriction, once the mainstay of clinical practice, has not shown to be of any additional benefit for patients in hospital or in the ambulatory care setting and therefore should be considered to be used cautiously (if at all) in clinical practice. Further developments and clinical trials are needed in this area to better identify patients who may benefit or have harm from these lower cost interventions and future research should focus on large scale, high quality, clinical trials rather than observational data to drive clinical practice.

RESUMO

Acute aortic syndromes (AAS) include a variety of overlapping anatomical and clinical conditions. Intramural hematoma (IMH), penetrating aortic ulcer, and aortic dissection occur in isolation or may coexist in the same patient. IMH represents 5-30% of all AAS and 60-70% of cases are located in the descending aorta. The diagnosis relies on a high index of clinical suspicion and on the use of complementary images. Management is conservative, but patients with some high-risk characteristics have a higher risk of mortality in the acute phase, so initial endovascular management should be considered. We present the case of a 69-year-old patient, in whom IMH was diagnosed in the course of a hypertensive emergency and who required hybrid management due to high-risk anatomical characteristics for endovascular management only.

RESUMO

Chronic Chagas cardiomyopathy (CCM) represents a relevant origin of Heart Failure (HF) in countries where the disease is endemic. CCM exhibits distinct myocardial involvement and is associated with a poorer prognosis compared to different HF etiologies. The aim is to explain the features and prognosis of individuals with HF resultant to CCM registered in the Colombian Registry of Heart Failure (RECOLFACA). RECOLFACA registry enrolled 2528 adult patients with HF. A comparison was made between patients diagnosed with CCM and those diagnosed with other etiologies of HF. Eighty-eight patients (3.5%) present CCM diagnosis. The individuals diagnosed with both HF and CCM were notably younger in age, had less comorbidities, poorer functional class, and significantly inferior ejection fraction. Finally, the presence of CCM diagnosis was linked to a substantially elevated mortality risk throughout the follow-up period (HR 2.01; 95% CI, 1.01-4.00) according to a multivariate model adjusted. CCM represents an important etiology of HF in Colombia, drawing attention to a distinct clinical profile and a higher risk of mortality compared to other HF etiologies.

RESUMO

INTRODUCTION: Chronic kidney disease (CKD) represents one of the most frequent comorbidities observed in heart failure (HF) patients and has been observed to increase this population's risk of adverse outcomes. Nevertheless, evidence analyzing kidney dysfunction in HF is scarce in Latin American populations. We aimed to analyze the prevalence of kidney dysfunction and assess its association with mortality in patients diagnosed with HF enrolled in the Colombian Heart Failure Registry (RECOLFACA). METHODS: RECOLFACA enrolled adult patients with HF diagnosis from 60 centers in Colombia during the period 2017-2019. The primary outcome was all-cause mortality. A Cox proportional-hazards regression model was used to assess the impact of the different categories of eGFR in mortality risk. A p value of <0.05 was considered significant. All statistical tests were two-tailed. RESULTS: From the total 2,514 evaluated patients, 1,501 (59.7%) patients had moderate kidney dysfunction (eGFR <60 mL/min/1.73 m2), while 221 (8.8%) patients were classified as having a severe kidney dysfunction (eGFR <30 mL/min/1.73 m2). Patients with lower kidney function were most commonly males, had higher median age, and reported a higher prevalence of cardiovascular comorbidities. Moreover, different patterns of medications prescription were observed when comparing CKD versus non-CKD patients. Finally, eGFR <30 mL/min/1.73 m2 was significantly associated with a higher mortality risk compared to eGFR >90 mL/min/1.73 m2 status (HR: 1.87; 95% CI, 1.10-3.18), even after an extensive adjustment by relevant covariates. CONCLUSION: CKD represents a prevalent condition in the setting of HF. Patients with CKD and HF present with multiple sociodemographic, clinical, and laboratory differences compared with those only diagnosed with HF and present a significantly higher risk of mortality. A timely diagnosis and optimal treatment and follow-up of CKD in the setting of HF may improve the prognosis of these patients and prevent adverse outcomes.

RESUMO

BACKGROUND: Heart failure (HF) is usually accompanied by cardiovascular and non-cardiovascular comorbidities, which may significantly impact its prognosis. In this study we aimed to characterize the comorbidity profile and its impact in mortality in patients with HF diagnosis from the Colombian Heart Failure Registry (RECOLFACA). METHODS: RECOLFACA enrolled adult patients with HF diagnosis from 60 centers in Colombia during the period 2017-2019. The primary outcome was all-cause mortality. A Cox proportional hazards regression model was used to assess the impact of the comorbidities in mortality. A p-value of <0.05 was considered significant. RESULTS: From the total 2528 patients included in the registry, 2514 patients (58% males, mean age 68 years) had information regarding comorbidity diagnoses. 2321 patients (92.3%) reported at least one comorbidity. Arterial hypertension was the most frequent individual diagnosis (72%; n = 1811), followed by anemia (30.1%, n = 726). The most frequently observed coexisting comorbidities were coronary disease (CHD) with dyslipidemia, and chronic kidney disease (CKD) with type 2 Diabetes Mellitus (T2DM). Different patterns of comorbidity coexistence were observed when comparing HF patients by sex and left-ventricular ejection fraction (LVEF) classification. The only comorbidities that were significantly associated with mortality after multivariate adjustment were T2DM (HR 1.45. 95% CI 1.01-2.12), anemia (HR 1.48. 95% CI 1.02-2.16), and CHD (HR 1.59. 95% CI 1.09-2.33). CONCLUSION: Multiple comorbidities were frequently observed in the patients from the RECOLFACA. T2DM, anemia and CHD were significantly associated with a higher risk of mortality, highlighting the importance of promoting an optimal follow-up and control of these conditions.

RESUMO

The prevalence of Heart Failure is growing alarmingly; its treatment consumes health resources and affects the quality of life of patients. To describe the changes in NYHA functional Class, ejection fraction, hospitalizations, and mortality after 8 years of follow up in a multidisciplinary heart failure program in Colombia as a model for lower and middle income countries. An observational study was performed with the retrospective analysis of the information. 1757 patients were included, The NYHA functional class at the beginning of the program was: NYHA I 23.5%, NYHA II 50.3%, NYHA class Improvement was observed at the end of the follow-up with an increase in the percentage of patients in Functional Class NYHA I and II. The reduction in hospitalizations were 35% less (mean: 0.68 ± 0.95, P < 0.0001), a reduction in the length of stay in the hospital was 13.2% (before: 4.46 ± 7.16, after 3.87 ± 8.1 days, P < 0.001). The total mortality after eight years of follow-up was 6.6 % (n = 116). Multidisciplinary follow-up in Heart Failure (HF) programs improves Functional Class and EF, decreases hospital admissions as well as hospitalization and the length of stay. This is a very simple and successful model of care for this disease that can be implemented for countries of lower- and middle-income countries.

RESUMO

Cysticercosis is a parasitic tissue infection caused by larval cysts of the tapeworm Taenia solium. These larval cysts infect brain, muscle, or other tissue, and are a major cause of adult-onset seizures in most low-income countries with tropical climate. Prevalence it's around 50 million people. Although cardiovascular system is not the most affected, this disease can also be associated with multiple and randomly distributed cysts in the subpericardium, subendocardium and myocardium in up to 25% of infected patients. Most cardiac cysticercosis' cases are asymptomatic, but it can manifest with ventricular arrhythmias and conduction disorders. Area Covered: The "Neglected Tropical Diseases and other Infectious Diseases affecting the Heart" (NET-Heart project) is an initiative by the Emerging Leaders group of the Interamerican Society of Cardiology to systematically review all these endemic conditions affecting the heart. A systematic review was conducted following preferred reporting items for systematic review and meta-analysis guidelines and including articles published in MEDLINE, ScienceDirect, PubMed and LILACS databases. A total of 41 papers were included in this review. Expert Opinion: In the areas of greatest prevalence, unhealthiness and poverty favor the development of this disease, which highlights the need to establish global health policies that reduce morbidity and mortality, economic losses of the affected population, and health costs related to hospitalizations for cardiovascular involvement. Authors provide an algorithm to evaluate the possibility of Cysticercosis' cardiovascular complications.

RESUMO

Introducción. En los pacientes con falla cardíaca, el sodio urinario se ha propuesto como marcador de gravedad y resistencia a los diuréticos, pero los resultados de los estudios reportados son heterogéneos. Objetivo. Evaluar el sodio en orina ocasional como factor pronóstico de mortalidad en pacientes con falla cardiaca descompensada. Materiales y métodos. Se realizó un análisis anidado de casos y controles de una cohorte prospectiva de falla cardíaca descompensada. El desenlace primario fue mortalidad a los 180 días. Se hizo un análisis bivariado para evaluar las variables que se asocian con la mortalidad. Se analizaron las diferencias de las variables clínicas entre los grupos con sodio urinario mayor o menor de 70 mEq/L. Resultados. Se incluyeron 79 pacientes de los cuales 15 fallecieron a los 180 días. La edad promedio fue de 68,9 años (DE: ±13,8), 30 eran mujeres (38 %). Quince pacientes (18,9 %) tuvieron un sodio en orina inferior a 70 mEq/L. En el análisis bivariado se encontró una asociación significativa de la mortalidad con las hospitalizaciones, la presión arterial sistólica inferior a 90 mm Hg, el uso de inotrópicos y el sodio urinario inferior a 70 mEq/L. Los pacientes con sodio urinario bajo habían estado hospitalizados con mayor frecuencia en el último año, tenían menores valores de sodio sérico y presión arterial al ingreso. Conclusión. Los pacientes con sodio urinario inferior a 70 mEq/L tienen características de mayor gravedad. En el análisis bivariado, el sodio urinario se asoció con mortalidad a los 180 días.

Introduction. Urinary sodium has been proposed as a prognostic marker and indicator of the diuretic response in patients with heart failure. However, study results are heterogeneous. Objective. To evaluate the spot urinary sodium level as a risk factor for mortality in patients with decompensated heart failure. Materials and methods. We conducted a case-control study nested in a prospective cohort of patients with decompensated heart failure. The primary outcome was mortality at 180 days. The risk factors associated with mortality were evaluated through a bivariate analysis. Differences in clinical variables between groups with urinary sodium greater than or lesser than 70 mEq/L were analyzed. Results. The study included 79 patients; 15 died at 180 days. Their mean age was 68.9 years (SD=± 13.8); 30 were women (38%), and 15 (18.9%) had urinary sodium <70 mEq/L. In the bivariate analysis, a significant association was found between mortality and past medical history of hospitalizations, SBP<90 mm Hg, the use of inotropes, and urinary sodium <70 mEq/L. Regarding clinical characteristics, patients with low urinary sodium level in the last year were hospitalized more frequently with hyponatremia and hypotension at admission. Conclusion. Patients with urinary sodium <70 mEq/L had more severe signs. In a bivariate analysis, urinary sodium was associated with mortality at 180 days.

En los pacientes con falla cardíaca, el sodio urinario se ha propuesto como marcador de gravedad y resistencia a los diuréticos, pero los resultados de los estudios reportados son heterogéneos. Objetivo. Evaluar el sodio en orina ocasional como factor pronóstico de mortalidad en pacientes con falla cardiaca descompensada. Materiales y métodos. Se realizó un análisis anidado de casos y controles de una cohorte prospectiva de falla cardíaca descompensada. El desenlace primario fue mortalidad a los 180 días. Se hizo un análisis bivariado para evaluar las variables que se asocian con la mortalidad. Se analizaron las diferencias de las variables clínicas entre los grupos con sodio urinario mayor o menor de 70 mEq/L. Resultados. Se incluyeron 79 pacientes de los cuales 15 fallecieron a los 180 días. La edad promedio fue de 68,9 años (DE: ±13,8), 30 eran mujeres (38 %). Quince pacientes (18,9 %) tuvieron un sodio en orina inferior a 70 mEq/L. En el análisis bivariado se encontró una asociación significativa de la mortalidad con las hospitalizaciones, la presión arterial sistólica inferior a 90 mm Hg, el uso de inotrópicos y el sodio urinario inferior a 70 mEq/L. Los pacientes con sodio urinario bajo habían estado hospitalizados con mayor frecuencia en el último año, tenían menores valores de sodio sérico y presión arterial al ingreso. Conclusión. Los pacientes con sodio urinario inferior a 70 mEq/L tienen características de mayor gravedad. En el análisis bivariado, el sodio urinario se asoció con mortalidad a los 180 días.
