Question: Does acute administration of conjugated equine oestrogen improve exercise-induced myocardial ischaemia in men with coronary artery disease?
Answer: Acute parenteral oestrogen therapy did not increase total exercise time or time to the onset of electrocardiographic changes of ischaemia in men with chronic stable coronary artery disease. These findings contrast the favourable effects of oestrogen in women in comparable studies and indicate a sex specificity for the acute cardiovascular effects of oestrogen.
A:
no
