No obstante, los autores subrayan que este hallazgo no debería ser motivo de alarma, sino más bien que los ciclos irregulares son indicativos de otras anomalías metabólicas que pueden predisponer a un mayor riesgo cardíaco.
El estudio se basa en cuestionarios contestados por más de 82.000 enfermeras cuando tenían entre 20 y 35 años de edad participantes en el Nurses' Health Study, que han sido seguidas durante más de 14 años.
Un total de 1.417 desarrollaron enfermedad cardíaca y 838 experimentaron un ictus. Si bien un ciclo menstrual irregular no parece asociarse al accidente cerebrovascular, sí está relacionado con el riesgo cardíaco.
Asimismo, señalan que muchas de las mujeres con ciclos irregulares presentaban síndrome de ovario poliquístico, que se ha relacionado con resistencia a la insulina, la cual, a su vez, incrementa el riesgo cardíaco.
