Los resultados de un estudio norteamericano indican que la insuficiencia cardíaca es una de las principales causas de muerte y discapacidad en el país.
Los resultados, publicados en el "American Journal of Medicine" por investigadores de la Universidad de Massachusetts, muestran el número de pacientes hospitalizados por insuficiencia cardíaca recién diagnosticada en un condado estadounidense desde el año 2000, así como las tasas de muerte y la evaluación de los factores pronósticos.
Se diagnosticaron 2.604 pacientes durante el período de estudio, lo que representa una tasa de 219 nuevos casos de insuficiencia cardíaca por cada 100.000 habitantes de la zona.
Los factores de riesgo fueron la edad avanzada y el sexo femenino. Específicamente, las tasas de insuficiencia cardíaca en mujeres fue de 250 casos por 100.000 habitantes y en varones de 194 por 100.000.
Alrededor del 5% de las personas que fueron hospitalizadas por insuficiencia cardíaca fallecieron, señala el artículo. Los factores de riesgo de desenlace mortal fueron la edad avanzada, la no presencia de sobrepeso, la historia de anemia o ictus, así como algunas anomalías detectadas en análisis clínicos.
