El estudio recoge los datos de los tres estudios más amplios de tratamiento de la insuficiencia cardíaca con betabloqueantes: el MERIT-HF (con metoprolol CR/XL), el CIBIS-II (bisoporolol) y el COPERNICUS (carvedilol), y concluye que los datos combinados de todos ellos muestran que el incremento de supervivencia es similar al registrado en hombres.
Centrándose en 898 mujeres participantes en el MERIT-HF, los investigadores registraron una reducción media de la mortalidad y la hospitalización del 21% por año en el grupo metoprolol CR/XL comparado con el placebo. Hubo, además, una reducción del 19% en la hospitalización por cualquier causa, del 29% por trastornos cardiovasculares y del 42% por infarto de miocardio.
