La doctora Bettina A. Hamelin y sus colegas, de la Universidad Laval (Quebec), examinaron a 28 mujeres que habían sufrido un infarto o una angina de pecho. "Un número significativamente mayor de mujeres sufrió el accidente coronario en los 5 días posteriores al inicio de la menstruación", señala el equipo de Hamelin.
El 43 por ciento de las mujeres tenía un nivel elevado de colesterol, un 42 por ciento padecía hipertensión y un 36 por ciento fumaba regularmente. Además el 24 por ciento había fumado anteriormente y el 7 por ciento padecía diabetes.
Los investigadores creen que las fluctuaciones en el nivel de estrógenos que tienen lugar durante el ciclo menstrual podrían afectar al riesgo de infarto.
"Las mujeres jóvenes deben recibir consejo sobre sus factores de riesgo cardiovascular, y las mujeres mayores deben seguir recibiendo consejo sobre los beneficios de una terapia de estrógenos sustitutiva", concluye la doctora Hamelin.
