Women taking HT had a significantly decreased incidence of fracture with long-term use .
Research ers found no strong evidence that HT has a clinical ly meaningful impact on the incidence of colorectal cancer .
AUTHORS ' CONCLUSIONS : Women with intolerable menopausal symptoms may wish to weigh the benefits of symptom relief against the small absolute risk of harm arising from short-term use of low-dose HT , provided they do not have specific contraindications .
HT may be unsuitable for some women , including those at increased risk of cardiovascular disease , increased risk of thromboembolic disease ( such as those with obesity or a history of venous thrombosis ) or increased risk of some types of cancer ( such as breast cancer , in women with a uterus ) .
The risk of endometrial cancer among women with a uterus taking oestrogen-only HT is well documented .
HT is not indicated for primary or secondary prevention of cardiovascular disease or dementia , nor for prevention of deterioration of cognitive function in postmenopausal women .
Although HT is considered effective for the prevention of postmenopausal osteoporosis , it is generally recommended as an option only for women at significant risk for whom non-oestrogen therapies are unsuitable .
BACKGROUND : Hormone therapy ( HT ) is widely provided for control of menopausal symptoms and has been used for the management and prevention of cardiovascular disease , osteoporosis and  dementia in older women .

Oestrogen therapy for prevention of reinfarction in postmenopausal women: a randomised placebo controlled trial.
BACKGROUND Results of observational studies suggest that hormone replacement therapy ( HRT ) could reduce the risk of coronary heart disease ( CHD ) , but those of r and omised trials do not indicate a lower risk in women who use oestrogen plus progestagen .  The aim of this study was to ascertain whether or not unopposed oestrogen reduces the risk of further cardiac events in postmenopausal women who survive a first myocardial infa rct ion . METHODS The study was a r and omised , blinded , placebo controlled , secondary prevention trial of postmenopausal women , age 50 - 69 years ( n=1017 ) who had survived a first myocardial infa rct ion . Individuals were recruited from 35 hospitals in Engl and and Wales . Women received either one tablet of oestradiol valerate ( 2 mg ; n=513 ) or placebo ( n=504 ) , daily for 2 years . Primary outcomes were reinfa rct ion or cardiac death , and all-cause mortality . Analyses were by intention-to-treat . Secondary outcomes were uterine bleeding , endometrial cancer , stroke or other embolic events , and fractures . FINDINGS Frequency of reinfa rct ion or cardiac death did not differ between treatment groups at 24 months ( rate ratio 0.99 , 95 % CI 0.70 - 1.41 , p=0.97 ) . Similarly , the reduction in all-cause mortality between those who took oestrogen and those on placebo was not significant ( 0.79 , 0.50 - 1.27 , p=0.34 ) . The relative risk of any death ( 0.56 , 0.23 - 1.33 ) and cardiac death ( 0.33 , 0.11 - 1.01 ) was lowest at 3 months post-recruitment . INTERPRETATION Oestradiol valerate does not reduce the overall risk of further cardiac events in postmenopausal women who have survived a myocardial infa rct ion
