Until recently, studies have indicated that hormone replacement therapy was successful in protecting a woman against heart disease.
However, a Swedish study which followed 1200 women for over 30 years has found that those who went on to use HRT already had a lower risk of heart disease than those that did not. They suggest that it is a result of individual good health and healthy lifestyle as well as the awareness of those in a higher socio-economic group that are the contributing factors in the reduction of heart disease. It may be tempting to suggest that this healthy user aspect may well account for other successes usually attributed to HRT.
