Resultados a 30 días en los pacientes mayores frágiles con insuficiencia cardiaca aguda dados de alta desde urgencias o sus unidades vinculadas que cumplen los criterios de alto riesgo del estudio DEED FRAIL-AHF / Thirty-day outcomes in frail older patients discharged home from the emergency department with acute heart failure: effects of high-risk criteria identified by the DEED FRAIL-AHF trial

RESUMEN

Objetivos: Estudiar el efecto a 30 días de los criterios de alto riesgo (CAR) en los mayores frágiles con insuficiencia cardiaca aguda (ICA) dados de alta desde urgencias o unidades vinculadas (URG_UV). Método: Análisis secundario del registro OAK-Discharge. Se seleccionaron pacientes frágiles $ 70 años con ICA dados de alta desde URG_UV. Los CAR se clasificaron en modificables (CAR_M) y no modificables (CAR_NM). Las variables de resultado fueron la compuesta cardiovascular (VC_CV) (revisita u hospitalización por ICA o mortalidad cardiovascular) y días vivos fuera del hospital (DVFH) a 30 días del alta. Resultados: Se incluyeron 380 pacientes con una edad media de 86 (DE 5,5) años, 61,2% mujeres. Un 65,1% tuvo CAR_M, 47,8% CAR_NM y 81,6% ambos. Ochenta y tres pacientes (21,8%) presentaron la VC_CV a 30 días. La media de DVFH a 30 días fue de 27,6 (DE 6,1) días. La presencia de CAR modificable, no modificable o ambos, se asoció más frecuentemente a la VC_CV a 30 días (25,0% vs 17,2%, p = 0,092; 27,6% vs 16,7%, p = 0,010; 24,7% vs15,2%, p = 0,098) y a menos DVFH a 30 días [26,9 (7,0) vs 28,4 (4,4), p = 0,011; 27,1 (7,0) vs 28,0 (5,0), p = 0,127; 27,1 (6,7) vs 28,8 (3,4), p = 0,005], respectivamente. Tras el análisis multivariante, los CAR_M se asociaron de forma independiente con menos DVFH a 30 días (diferencia absoluta ajustada –1,3 días; IC 95% –2,7 a –0,1) y los CAR_NM con más eventos en la VC_CV a 30 días (diferencia absoluta ajustada 10,4%; IC 95% 2,1% a 18,7%).

ABSTRACT

Objectives: To study the effect of high-risk criteria on 30-day outcomes in frail older patients with acute heart failure (AHF) discharged from an emergency department (ED) or an ED’s observation and short-stay areas. Methods.Secondary analysis of discharge records in the Older AHF Key Data registry. We selected frail patients (aged > 70 years) discharged with AHF from EDs. Risk factors were categorized as modifiable or nonmodifiable. The outcomes were a composite endpoint for a cardiovascular event (revisits for AHF, hospitalization for AHF, or cardiovascular death) and the number of days alive out-of-hospital (DAOH) within 30 days of discharge. Results: We included 380 patients with a mean (SD) age of 86 (5.5) years (61.2% women). Modifiable risk factors were identified in 65.1%, nonmodifiable ones in 47.8%, and both types in 81.6%. The 30-day cardiovascular composite endpoint occurred in 83 patients (21.8%). The mean 30-day DAOH observed was 27.6 (6.1) days. High-risk factors were present more often in patients who developed the cardiovascular event composite endpoint the rates for patients with modifiable, nonmodifiable, or both types of risk were, respectively, as follows in comparison with patients not at high risk 25.0% vs 17.2%, P = .092; 27.6% vs 16.7%, P = .010; and 24.7% vs 15.2%, P = .098). The 30-day DAOH outcome was also lower for at-risk patients, according to type of risk factor present modifiable, 26.9 (7.0) vs 28.4 (4.4) days, P = .011; nonmodifiable, 27.1 (7.0) vs 28.0 (5.0) days, P = .127; and both, 27.1 (6.7) vs28.8 (3.4) days, P = .005). After multivariate analysis, modifiable risk remained independently associated with fewer days alive (adjusted absolute difference in 30-day DAOH, –1.3 days (95% CI, –2.7 to –0.1 days). Nonmodifiable factors were associated with increased risk for the 30-day cardiovascular composite endpoint (adjusted absolute difference, 10.4%; 95% CI, –2.1% to 18.7%). (AU)
