Zusammenfassung: | To analyze survival in heart failure (HF) patients treated at a specialized unit.
Prospective cohort-based study of HF patients treated at a specialized unit from 2011 to 2017. Observed 1- and 3-year mortality rates were compared with those predicted by the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) risk score.
We studied 1280 patients, whose median MAGGIC risk score was 19 [interquartile range, 13-24]. Prescription rates of beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, mineralocorticoid receptor antagonists, and sacubitril-valsartan were 93%, 67%, 22%, 73%, and 16%, respectively. The MAGGIC risk score showed good discrimination for mortality at 1 year (c-statistic=0.71) and 3 years (c-statistic=0.76). Observed mortality was significantly lower than predicted mortality, both at 1 year (6.2% vs 10.9%; observed/predicted ratio=0.57; P 40% (19.6% vs 20.7%; observed/predicted ratio=0.95; P=.640).
Mortality in HF patients treated at a specialized clinic was significantly lower than that predicted by the MAGGIC risk score.
Analizar la supervivencia de los pacientes con insuficiencia cardiaca (IC) tratados en una unidad especializada.
Estudio prospectivo de una cohorte de pacientes con IC tratados en una unidad especializada entre 2011 y 2017. Se comparó la mortalidad observada a 1 y 3 años con la mortalidad pronosticada por la puntuación de riesgo del Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC).
Se estudió a 1.280 pacientes, con una mediana de la puntuación MAGGIC de 19 [intervalo intercuartílico, 13-24]. Las tasas de prescripción de bloqueadores beta, inhibidores de la enzima de conversión de la angiotensina, antagonistas del receptor de la angiotensina II, antagonistas del receptor de mineralcorticoides y sacubitrilo-valsartán fueron del 93, el 67, el 22, el 73 y el 16% respectivamente. La puntuación MAGGIC mostró una discriminación adecuada de la mortalidad a 1 año (estadístico c=0,71) y a 3 años (estadístico c=0,76). La mortalidad observada fue significativamente menor que la pronosticada, tanto a 1 año (el 6,2 frente al 10,9%; cociente observada/pronosticada=0,57; p |
