Explican que la neumonía ocupa en Estados Unidos el séptimo lugar entre las causas de muerte y constituye la primera causa de infección. La enfermedad mata cada año a 40.000 estadounidenses.
Los autores midieron el riesgo de muerte por neumonía en pacientes ingresados a causa de esta enfermedad que habían sido tratados con estatinas anteriormente. Comprobaron el riesgo con pacientes no usuarios de estos fármacos y utilizaron en Índice de Gravedad de la Neumonía para determinar el riesgo de muerte a los 30 días de la admisión en el hospital. Los resultados muestran que aquellos pacientes que recibían estatinas tienen 2,8 veces menos riesgo de morir que aquellos que no tomaban estos hipolipemiantes.
Advierten que es necesario investigar más para explicar este aparente efecto protector de las estatinas.
