ABSTRACT
The impact of chronic obstructive pulmonary disease (COPD) on heart failure (HF) has yet to be well assessed in the Latin American population. This study aimed to analyze the impact of COPD on HF patients from the Colombian Heart Failure Registry (RECOLFACA). The primary outcome was all-cause mortality. A Cox proportional-hazards regression model was used to assess the impact of COPD on mortality. From the total of 2528 patients in the registry, 2514 patients had information regarding COPD diagnosis. COPD diagnosis was associated with a worse functional class and higher use of diuretics than non-COPD patients (p < 0.001). Patients with this comorbidity had a significantly better ejection fraction (median ejection fraction 35% vs. 32% in non-COPD patients; p = 0.004), with a higher occurrence of HF with preserved ejection fraction (HFpEF) in the COPD group (p = 0.000). Finally, patients with COPD had a significantly higher risk of mortality in the multivariate regression model (HR 1.47; 95% CI 1.02, 2.11). COPD is a prevalent comorbidity among patients with HF in Colombia, showing a different clinical profile and a worse functional class than patients without this condition. Patients with COPD and HFpEF have a high mortality risk according to our results.
ABSTRACT
The effect of the health insurance type on the prognosis of heart failure (HF) patients in Colombia and Latin America is poorly known. We aimed to analyze the characteristics of HF patients that participated in the Colombian Heart Failure Registry (RECOLFACA) as stated by their health insurance type and their relationship with the immediate prognosis of these patients. Patients with HF diagnosis were included in the RECOLFACA registry between 2017-2019. The registry was conducted in 60 centers in Colombia. All-cause mortality was the principal outcome. To evaluate the impact of health insurance on mortality, a Cox proportional hazards regression model was used. The Kaplan-Meier analysis was performed to compare survival probabilities according to insurance type. All statistical analyses were two-tailed and were considered significant with a p value < 0.05. Of the 2,528 participants enrolled in the registry, 99% held details about their health insurance. Of those, 897 patients (35.6%) were covered by public insurance. These patients were significantly younger, with a lower proportion of men, more frequently from rural origin, and lower prevalence of most comorbidities (omitting hypertension, chronic obstructive pulmonary disease (COPD), and Chagas disease) than those with private insurance. Furthermore, patients with public insurance had a worse functional class, as well as a poorer quality of life, and lower frequency of use of implantable devices, while exhibiting similar prescription rates of triple medical therapy for HF. Finally, no differences in short-term mortality were observed between the two groups (HR 1.09; 95% CI 0.79, 1.51). The type of health insurance represents a condition related with relevant differences in the profile of patients with HF in Colombia. Despite this, no significant differences were detected in the short-term prognosis of these patients based on the type of health insurance.
ABSTRACT
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.

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.

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.
