The IMAGE Group and the Division of Geriatrics
at the University of Colorado Anschutz Medical Campus is currently recruiting healthy women between 18-40 years, 40-55 years, and 45-70 years of age.
Purpose of the Study:
As women get older and go through menopause, reproductive hormones (e.g., estrogen) decrease to low levels. Also, with aging the arteries that are located around the heart get stiffer. Over time this increase in arterial stiffness can lead to a number of health problems including high blood pressure and heart disease. In this study we want to find out if a short-term drop in estrogen levels can cause arteries to become stiffer, and the reasons why they become stiffer. Additionally, if you are a postmenopausal woman, we want to find out if a short-term increase in estrogen levels causes your arteries to become more flexible (less stiff).
