Hormonal

Conjugated equine estrogen (CEE) alone does not reduce the incidence of coronary heart disease in postmenopausal women with prior hysterectomy.

If you have had a hysterectomy and are considering hormone therapy for heart disease prevention, current evidence shows it does not work for that purpose. While it may help with bone density (hip fractures), it increases stroke risk. Do not use CEE solely to protect your heart.

The use of CEE increases the risk of stroke, decreases the risk of hip fracture, and does not affect CHD incidence in postmenopausal women with prior hysterectomy over an average of 6.8 years.
