Trial Name: Kronos Early Estrogen Prevention Study (KEEPS)

Type of Study: Menopause/Hormone

Dr. Marcelle I. Cedars from the UCSF Department of Obstetrics and Gynecology, Division of Reproductive Endocrinology, along with 7 other investigators at prominent medical centers around the country, will be conducting a study called the Kronos Early Estrogen Prevention Study (KEEPS). KEEPS is a 5 year study in which the investigators hope to learn whether estrogen treatment slows hardening of the arteries (atherosclerosis) in women if started soon after menopause. Atherosclerosis (hardening of the arteries) is the disease process that causes most heart attacks. KEEPS will also test for other possible good and bad effects of estrogen relative to heart disease. This is an Investigator-Initiated study meaning that the investigators have initiated and designed the study without any other influences. KEEPS is funded by the Aurora Foundation (a private foundation with no pharmaceutical affiliations), and is Sponsored by the Kronos Longevity Research Institute (KLRI) in Phoenix, Arizona who will be functioning as the Coordinating Center throughout the study.
