There remains enormous controversy concerning the treatment of depression in women, particularly the depression that is premenstrual and postnatal and in the menopausal transition which, in the view of many, should be treated with transdermal estrogens. The role of estrogens is, however, less clear in the postmenopausal woman.
We know that depression is associated with considerable pathology, apart from the risk of suicide, such as more heart attacks, more strokes, more osteoporosis, more hypertension, more obesity, more Alzheimer’s disease and more non-suicide deaths.
In a recent paper, Jordan Smoller and colleagues have focused entirely upon the Women’s Health Initiative (WHI) study . The cohort was based on the three WHI clinical trials and the WHI observational study.
Professor Smoller examined the postmenopausal women who were not taking antidepressants at baseline ([i]n[/i] = 136,293), of whom 4% ([i]n[/i] =5496) reported on the use of some antidepressant at one of the next follow-up visits; 55.3% ([i]n[/i] = 3040) were taking only selective serotonin reuptake inhibitors (SSRIs), 27.1% ([i]n[/i] = 1490) used tricyclics only, and 17.6% ([i]n[/i] = 966) another antidepressant or multiple antidepressants.
The mean follow-up after the first follow-up visit was 5.9 years. Among the analytic cohort, there were 6262 deaths, 2357 strokes, and 2983 coronary heart disease events during follow-up. Those subsequently taking antidepressants were compared with those patients who did not use antidepressants. There was found to be a 45% increase in stroke, but no significant increase in the risk for ischemic stroke. However, a 210% increase in fatal stroke and a 212% increase in hemorrhagic stroke were recorded. The all-cause mortality was increased by 32%. There was no increase in coronary heart disease with the use of antidepressants and there were no significant differences in risk between SSRIs and tricyclic antidepressants.
