Antipsychotics are effective in preventing relapses of schizophrenia, but it is generally believed that their long‐term use harmful for patients’ physical well‐being.

Objective: Data on the health benefits and risks of postmenopausal hormone therapy (HT) are derived mainly from use conjugated equine estrogens. Estradiol-based regimens may have a different risk-benefit profile. We evaluated risk death caused by coronary heart disease (CHD), stroke, or any among users estradiol-based HT in nationwide study Finland. Methods: A total 489,105 women who used 1994 to 2009 (3.3 million exposure years), as indicated reimbursement register national Cause Death...

Current guidelines recommend annual discontinuation of postmenopausal hormone therapy (HT) to evaluate whether a woman could manage without the treatment. The impact HT on cardiovascular health has been widely studied, but it is not known how withdrawal affects risk.We evaluated risk cardiac or stroke death after HT. Design, Patients, Interventions, and Main Outcome Measures: Altogether 332 202 Finnish women discontinuing between 1994 2009 (data from National Reimbursement register) were...

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 age, protects the heart but endangers it later (Women's Health Initiative study). Less is known about natural estradiol (ET) various progestins (EPT). We related death risk from coronary disease (CHD) users ET EPT age at initiation therapy and progestin component EPT.

To assess whether coronary heart disease mortality in Finnish hormone therapy (HT) users differed before and after 2002 when the Women's Health Initiative study was published.The risks of death HT relation to age-matched background population were compared between pre- (1995-2001) post- (2002-2009) eras.

Does the use of post-menopausal vaginal estradiol (VE) affect mortality risk for coronary heart disease (CHD) and stroke. The VE reduces cardiovascular mortality. A growing number women genitourinary symptoms. Although this therapy is intended to have only local effects, estrogen absorbed into blood circulation thus may also systemic effects. We studied a nationwide cohort in Finland 1994–2009 during which (n = 195 756) initiated (age [mean ± SD] 65.7 10.9 years). Follow-up data gathered 1.4...
