Clinical presentation and outcomes of acute heart failure in the critically ill patient: A prospective, observational, multicentre study / Presentación clínica y resultados de la insuficiencia cardíaca aguda en el paciente crítico: estudio prospectivo, observacional y multicéntrico

Aims To assess the clinical profile and factors associated with 30-day mortality in patients with acute heart failure (AHF) admitted to the intensive care unit (ICU). Design Prospective, multicentre cohort study. Scope Thirty-two Spanish ICUs. Patients Adult patients admitted to the ICU between April and June 2017. Intervention Patients were classified into three groups according to AHF status: without AHF (no AHF); AHF as the primary reason for ICU admission (primary AHF); and AHF developed during the ICU stay (secondary AHF). Main variables of interest Incidence of AHF and 30-day mortality. Results A total of 4330 patients were included. Of these, 627 patients (14.5%) had primary (n=319; 7.4%) or secondary (n=308; 7.1%) AHF. Among the main precipitating factors, fluid overload was more common in the secondary AHF group than in the primary group (12.9% vs 23.4%, p<0.001). Patients with AHF had a higher risk of 30-day mortality than those without AHF (OR 2.45; 95% CI: 1.93–3.11). APACHE II, cardiogenic shock, left ventricular ejection fraction, early inotropic therapy, and diagnostic delay were independently associated with 30-day mortality in AHF patients. Diagnostic delay was associated with a significant increase in 30-day mortality in the secondary group (OR 6.82; 95% CI 3.31–14.04). Conclusions The incidence of primary and secondary AHF was similar in this cohort of ICU patients. The risk of developing AHF in ICU patients can be reduced by avoiding modifiable precipitating factors, particularly fluid overload. Diagnostic delay was associated with significantly higher mortality rates in patients with secondary AHF (AU)

Objetivos Evaluar el perfil clínico y los factores asociados con la mortalidad a 30 días en pacientes con insuficiencia cardíaca aguda (ICA) ingresados en Unidades de Cuidados Intensivos (UCI). Diseño Prospectivo, multicéntrico. Ámbito 32 UCI españolas. Pacientes Pacientes adultos ingresados en UCI entre abril y junio de 2017. Intervención Los pacientes se clasificaron en tres grupos según el estado de la ICA: sin ICA (no ICA), ICA como motivo principal de ingreso en UCI (ICA-primaria), e ICA desarrollada durante la estancia en UCI (ICA-secundaria). Principales variables de interés Incidencia de ICA y mortalidad a los 30 días. Resultados Se incluyeron 4.330 pacientes, de estos, 627 (14,5%) tenían ICA-primaria (n = 319; 7,4%) o secundaria (n = 308; 7,1%). Entre los principales factores precipitantes, la sobrecarga hídrica fue más común en el grupo ICA-secundaria que el ICA-primaria (12,9 vs. 23,4%, p < 0,001). Los pacientes con ICA tuvieron un mayor riesgo de mortalidad que los que no tenían ICA (OR 2,45; IC 95%: 1,93-3,11). APACHE II, choque cardiogénico, fracción de eyección del ventrículo izquierdo, tratamiento precoz con inotrópicos y el retraso diagnóstico se asociaron de forma independiente con la mortalidad en los pacientes con ICA. El retraso diagnóstico se asoció con un aumento significativo de mortalidad en el grupo secundario (OR 6,82; IC 95%: 3,31-14,04). Conclusiones La incidencia de ICA primaria y secundaria fue similar. El riesgo de desarrollar ICA en pacientes críticos puede reducirse evitando factores precipitantes modificables, en particular la sobrecarga de líquidos. El retraso diagnóstico se asoció con mayor mortalidad en pacientes con ICA-secundaria (AU)
