Asimismo, indican que la presencia de disfunción eréctil puede ser un predictor de gravedad y mal pronóstico en pacientes cardíacos.
Uno de los artículos muestra que tras la comercialización de nuevos fármacos para este trastorno en 1998, se produjo un incremento del 50% en las visitas al médico por este motivo.
Los autores analizaron datos de 2.126 varones mayores de 20 años, participantes en una encuesta de ámbito nacional entre 2001 y 2002. Los resultados muestran que la prevalencia global de la disfunción eréctil es del 18,4% y que está relacionada claramente con la edad, de modo que afecta sólo al 6,5% de los varones de 20 a 29 años, pero al 77,5% de los mayores de 75.
