Autonomic regulation of blood pressure in premature and early menopausal women


The goal of this study is to learn more about the effects of menopause on women's blood pressure and heart health. We are looking for women between the ages of 35 and 70 years to participate in the study. Participants may be pre- or postmenopausal; we are specifically interested in evaluating the influence of premature (< age 40 years) and early (< age 46 years) menopause.
