RESUMO
Objetivo: Estimar la incidencia de diagnóstico de insuficiencia cardiaca aguda (ICA) en pacientes mayores en los servicios de urgencias (SU), la confirmación diagnóstica de la ICA en pacientes hospitalizados y los eventos adversos a corto plazo. Método: Se incluyeron a todos los pacientes de ≥65 años atendidos en 52 SU españoles durante una semana y se seleccionaron los diagnosticados de ICA. En los hospitalizados se recogieron los diagnosticados de ICA al alta. Como eventos adversos, se recogió la mortalidad intrahospitalaria y a 30 días, y evento adverso combinado (muerte u hospitalización) a 30 días posalta. Se calcularon las odds ratio (OR) ajustadas de las características demográficas, de estado basal y a la llegada al SU asociadas con mortalidad y evento adverso posalta a 30 días. Resultados: Se incluyeron 1.155 pacientes con ICA (incidencia anual: 26,5 por 1.000 habitantes ≥65 años, IC95%: 25,0-28,1). En el 86%, el diagnóstico de ICA constaba al alta. La mortalidad global a 30 días fue del 10,7%, la intrahospitalaria del 7,9% y el evento combinado posalta del 15,6%. La mortalidad intrahospitalaria y a 30 días se asoció con hipotensión arterial (OR ajustada: 74,0, IC95%: 5,39-1.015.; y 42,6, 3,74-485, respectivamente) e hipoxemia (2,14, 1,27-3,61; y 1,87, 1,19-2,93) a la llegada a urgencias y con precisar ayuda en la deambulación (2,24, 1,04-4,83; y 2,48, 1,27-4,86) y la edad (por cada incremento de 10 años; 1,54, 1,04-2,29, y 1,60, 1,13-2,28). Conclusiones: La ICA es un diagnóstico frecuente en los pacientes mayores que consultan en los SU. El deterioro funcional, la edad, la hipotensión e hipoxemia son los factores que más se asocian a mortalidad.(AU)
Objective: To estimate the incidence of acute heart failure (AHF) diagnosis in elderly patients in emergency departments (ED), diagnostic confirmation in hospitalized patients, and short-term adverse events. Methods: All patients aged ≥65 years attended in 52 Spanish EDs during 1 week were included and those diagnosed with AHF were selected. In hospitalized patients, those diagnosed with AHF at discharge were collected. As adverse events, in-hospital and 30-day mortality, and combined adverse event (death or hospitalization) at 30 days post-discharge were collected. Adjusted odds ratios (OR) for association of demographic variables, baseline status and constants at ED arrival with mortality and 30-day post-discharge adverse event were calculated. Results: We included 1,155 patients with AHF (annual incidence: 26.5 per 1000 inhabitants ≥65 years, 95%CI: 25.0-28.1). In 86% the diagnosis of AHF was known at discharge. Overall 30-day mortality was 10.7% and in-hospital mortality was 7.9%, and the combined event in 15.6%. In-hospital and 30-day mortality was associated with arterial hypotension (adjusted OR: 74.0, 95%CI: 5.39-1015. and 42.6, 3.74-485, respectively and hypoxemia (2.14, 1.27-3.61; and 1.87, 1.19-2.93) on arrival at the ED and requiring assistance with ambulation (2.24, 1.04-4.83; and 2.48, 1.27-4.86) and age (per 10-year increment; 1.54, 1.04-2.29; and 1.60, 1.13-2.28). The combined post-discharge adverse event was not associated with any characteristic. Conclusions: AHF is a frequent diagnosis in elderly patients consulting in the ED. The functional impairment, age, hypotension and hypoxemia are the factors most associated with mortality.(AU)
