In relatively healthy women , combined continuous HT significantly increased the risk of venous thrombo-embolism or coronary event ( after one year 's use ) , stroke ( after three years ) , breast cancer and gallbladder disease .
Long-term oestrogen-only HT significantly increased the risk of venous thrombo-embolism , stroke and gallbladder disease ( after one to two years , three years and seven years ' use respectively ) , but did not significantly increase the risk of breast cancer .
The only statistically significant benefits of HT were a decreased incidence of fractures and ( for combined HT ) colon cancer , with long-term use .
Among women aged over 65 who were relatively healthy ( i.e. generally fit , without overt disease ) and taking continuous combined HT , there was a statistically significant increase in the incidence of dementia .
Among women with cardiovascular disease , long-term use of combined continuous HT significantly increased the risk of venous thrombo-embolism .

Estrogen plus progestin and the risk of coronary heart disease.
BACKGROUND Recent r and omized clinical trials have suggested that estrogen plus progestin does not confer cardiac protection and may increase the risk of coronary heart disease ( CHD ) . In this report , we provide the final results with regard to estrogen plus progestin and CHD from the Women 's Health Initiative ( WHI ) . METHODS The WHI included a r and omized primary -prevention trial of estrogen plus progestin in 16,608 postmenopausal women who were 50 to 79 years of age at base line . Participants were r and omly assigned to receive conjugated equine estrogens ( 0.625 mg per day ) plus medroxyprogesterone acetate ( 2.5 mg per day ) or placebo . The primary efficacy outcome of the trial was CHD ( nonfatal myocardial infa rct ion or death due to CHD ) . RESULTS After a mean follow-up of 5.2 years ( planned duration , 8.5 years ) , the data and safety monitoring board recommended terminating the estrogen-plus-progestin trial because the overall risks exceeded the benefits . Combined hormone therapy was associated with a hazard ratio for CHD of 1.24 ( nominal 95 percent confidence interval , 1.00 to 1.54 ; 95 percent confidence interval after adjustment for sequential monitoring , 0.97 to 1.60 ) . The elevation in risk was most apparent at one year ( hazard ratio , 1.81 [ 95 percent confidence interval , 1.09 to 3.01 ] ) . Although higher base-line levels of low-density lipoprotein cholesterol were associated with an excess risk of CHD among women who received hormone therapy , higher base-line levels of C-reactive protein , other biomarkers , and other clinical characteristics did not significantly modify the treatment-related risk of CHD . CONCLUSIONS Estrogen plus progestin does not confer cardiac protection and may increase the risk of CHD among generally healthy postmenopausal women , especially during the first year after the initiation of hormone use . This treatment should not be prescribed for the prevention of cardiovascular disease
