Factores determinantes del déficit cognitivo en la insuficiencia cardiaca congestiva Deciding factors of cognitive deficit in congestive heart failure

Abstract

La insuficiencia cardiaca congestiva constituye una de las principales causas de hospitalización, morbilidad y mortalidad en los países occidentales. Aunque en Colombia no se conocen con exactitud su incidencia y prevalencia, recientemente se ha planteado que está adquiriendo proporciones epidémicas. Diversos estudios demuestran que los pacientes con esta condición presentan alteraciones cognitivas tales como pérdida de la memoria y déficit de atención, las cuales se relacionan con un peor pronóstico clínico. Los síntomas cognitivos no sólo indican una enfermedad cardiaca más avanzada, sino que también se asocian con pobre adherencia al tratamiento y menor calidad de vida. A pesar de su importancia, los mecanismos fisiopatológicos de esta relación no son claros. Se sugiere que las alteraciones hemodinámicas cerebrales derivadas de la disminución en el gasto cardiaco, así como de la presencia de múltiples microinfartos cerebrales secundarios a microembolismos, podrían relacionarse con alteraciones cognitivas en dichos pacientes. Sin embargo, hasta el momento no existen suficientes datos que permitan confirmar esta hipótesis.Congestive heart failure is a leading cause of hospitalization, morbidity and mortality in the Western countries. Although its incidence and prevalence in Colombia is not fully established, it seems to be acquiring epidemic proportions. Several studies have shown that patients with congestive heart failure present cognitive impairments such as memory loss and attention deficit, which are associated with a worse clinical prognosis. The cognitive symptoms are not only indicative of a more advanced heart disease but are also associated with poor adherence to treatment and lower quality of life. Despite their importance, the pathophysiological mechanisms of this relationship have not been clearly defined. It has been suggested that the cerebral hemodynamic changes resulting from a decrease in cardiac output and from the presence of multiple brain microinfarctions secondary to microembolisms could be related to cognitive impairment in patients with congestive heart failure. However, until now no sufficient data are available to confirm this hypothesis.
