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.

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
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.
