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: 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.

Resumen Introducción: la estimación temprana del riesgo en falla cardiaca aguda puede ayudar en la toma de decisiones clínicas. Objetivo: identificar los factores de riesgo asociados a mortalidad intrahospitalaria en pacientes con falla cardiaca aguda. Métodos: análisis de una cohorte retrospectiva de pacientes mayores de 18 años ingresados a hospitalización por falla cardiaca aguda en un hospital de tercer nivel, entre los años 2012 y 2016. Resultados: se incluyeron 247 pacientes, con edad promedio de 62,8 años; predominó el sexo masculino con un 60%. El 84% de los pacientes tenía falla cardiaca con fracción de expulsión disminuida (mediana de 25%). La mortalidad intrahospitalaria fue de 9,3% y la acumulada a 30 días y 6 meses posterior al egreso hospitalario fue de 10,9 y 14,1%, respectivamente. Los dos predictores asociados a muerte intrahospitalaria fueron el nitrógeno ureico en sangre (BUN)> 37 mg/dl (OR: 10,8; 95% IC: 4,10-28,8) y la presión arterial sistólica (PAS) ≤ 125 mm Hg (OR: 3,42; 95% IC:1,15-10,0). El modelo de árbol de regresión y clasificación (CART) identificó como el mejor predictor de mortalidad los niveles elevados de BUN (≥ 32,5 mg/dl), seguido por la presión sistólica disminuida (< 97 mm Hg) y finalmente por los niveles elevados de creatinina (≥ 1,75 mg/dl). Conclusión: el análisis mediante el CART permite clasificar en forma temprana la probabilidad de muerte por un árbol de riesgo que incluye el BUN ≥ 32,5 mg/dl, la presión sistólica < 97 mm Hg y los niveles de creatinina ≥ 1,75 mg/dl.
Abstract Introduction: The early estimation of risk in acute heart failure may help in the taking of clinical decisions. Objective: To identify the risk factors associated with in-hospital mortality in patients with acute heart failure. Methods: An analysis was performed on a retrospective cohort of patients greater than 18 years admitted to a tertiary hospital due acute heart failure between the years 2010 and 2016. Results: A total of 247 patients were included, with a mean age of 62.8 years, and of which 60% were male. The large majority (84%) of the patients had heart failure with a reduced ejection fraction (median 25%). The in-hospital mortality was 9.3%, and the accumulated rate at 30 days and 6 months after hospital discharge was 10.9% and 14.1%, respectively. The two predictors associated with in-hospital death was a blood urea nitrogen (BUN) > 37 mg/dL (OR: 10.8; 95% CI: 4.10-28.8) and a systolic blood pressure (SBP) ≤ 125 mmHg (OR: 3.42; 95% CI: 1.15-10.0). The classification and regression tree (CART) model identified elevated levels of as the best predictor of mortality, followed by a decreased systolic pressure (< 97 mmHg), and finally due to elevated creatinine levels (≥ 1,75 mg/dL). Conclusion: The analysis using the classification and regression tree (CART) model can provide an early classification of the probability of death by a risk tree that includes BUN ≥ 32.5 mg/dL, systolic pressure <97 mm Hg, and creatinine levels ≥ 1.75 mg/dL.

Triatoma dimidiata (Latreille) is considered to be one of the primary vectors of Chagas disease in Southern Mexico and Central America. The objective of the present study was to obtain ecological information on T. dimidiata in two rural communities of Campeche, Mexico, where the vector is poorly studied. Our work consisted of monthly samplings carried out during one-year time at three levels: sylvatic, peridomestic and intradomestic, in order to estimate the population abundance of this species and its rate of infection with Trypanosoma cruzi. Triatoma dimidiata was the unique vector of this disease collected in San Juan Bautista Sakcabchen (SJBS) and Crucero San Luis (CSL). The total of 145 individuals were captured in SJBS; from these, 26.9 percent, 20 percent and 53.1 percent were collected in the sylvatic, peridomestic and intradomestic area, respectively. In CSL captures yielded 108 individuals: 40.7 percent in the sylvatic area, 20.4 percent peridomestic and 38.9 percent intradomestic. We found no correlation between climatic variables and population abundance of T. dimidiata. Dataset obtained suggests that individuals from the sylvatic area exhibit a high rate of natural infection by T. cruzi, with monthly percentages up to 61.5 percent for SJBS and 50 percent for CSL. At the peri and intradomestic level, the reservoirs apparently play an important role in the transmission, as the seroprevalence in dogs was 61.5 percent y 65.4 percent, for SJBS y CSL, respectively. Based on these findings, it was concluded that inhabitants of both communities are at a high risk of Chagas disease infection.
