Context: Women with a history of pre-eclamptic pregnancy are predisposed to later occlusive vascular diseases.

Objective: We compared the use of cyclic progestins or levonorgestrel-releasing intrauterine device (LNG-IUD) for treatment of menstrual cycle abnormalities between premenopausal women with and without a prior pre-eclamptic pregnancy.

Setting And Participants: Register-based cohort study during 1994-2019 of oral progestin or levonorgestrel-releasing intrauterine device (LNG-IUD) in Finnish women with (n=31 688) and without (n=91 726) prior pre-eclampsia in 1969-1993.

We summarize convincing evidence that future cardiovascular disease (CVD) risk increases one-fold to four-fold for women with a history of pregnancy complicated by hypertensive disorders, gestational diabetes, fetal growth restriction, placental abruption and preterm birth. A concomitant occurrence of two or more complications in the same pregnancy further potentiates the risk. These women should be informed of their future CVD risks during the postpartum check-up taking place after delivery, and also, if needed, treated, for example, for persisting high blood pressure.

Objective: Receptors for estrogen and progesterone are present in the pelvic floor, and therefore, postmenopausal hormone therapy may affect its function. We compared the former use of estradiol-progestogen postmenopausal hormone therapy in nonhysterectomized women with a uterine prolapse surgery (N = 12,072) and control women (N = 33,704).

Methods: The women with a history of uterine prolapse operation were identified from the Finnish National Hospital Discharge Register, and the control women from the Finnish Central Population Register.

Objective: The aim of the study was to evaluate the risk of cardiac and stroke deaths in women who discontinue postmenopausal hormone therapy (HT).

Methods: We analyzed the risk of death due to cardiac (n = 5,204) and cerebrovascular (n = 3,434) causes in Finnish women who discontinued systemic HT during 1994 to 2013 (n = 432,775). The risks were compared with those in the age-matched female background population and with those in age-matched HT users.

Coronary artery disease (CAD) is still the most common killer of western women. Coronary arteries, expressing estrogen receptors, are a target for estrogen action. Prior to the Women's Health Initiative (WHI) study, postmenopausal hormone therapy (HT) was widely advocated for primary prevention of CAD, but such use was criticized after the WHI publication.

Context: The "window of opportunity hypothesis" refers to data indicating that conjugated equine estrogen alone or in combination with medroxyprogesterone acetate, if initiated before 60 years of age, protects the heart but endangers it if initiated later (Women's Health Initiative study). Less is known about the "window of opportunity hypothesis" with natural estradiol alone (ET) or with various progestins in combination with estradiol (EPT).

Objective: We related the death risk from coronary heart disease (CHD) in users of ET or EPT to the age at the initiation of therapy and to the progestin component of EPT.

Objective: Because premenstrual symptoms in fertile age resemble menopausal symptoms, many women with premenstrual symptoms fear that they have an increased risk for developing vasomotor symptoms in menopause. We investigated the impact of premenstrual symptoms on the occurrence and severity of menopausal vasomotor symptoms and quality of life.

Methods: One hundred fifty recently postmenopausal healthy women recorded hot flashes prospectively (23, none; 34, mild; 30, moderate; 63, severe), and their quality of life was assessed using the Women's Health Questionnaire.
