Evidence from two groups of post-menopausal women who were randomly allocated to be treated with either conjugated equine oestrogens or piperazine oestrone sulphate demonstrates that the two oestrogens produce markedly different effects on blood pressure. The conjugated equine oestrogens appear to produce no significant change in either systolic or diastolic blood pressure whereas piperazine oestrone sulphate produced a significant fall in both systolic and diastolic blood pressure. This finding is discussed in relationship to the known causes for a change in cardiovascular response to oestrogen and several hypotheses are put forward.
