Hi
dear
HRT is associated with increased risk of cardiac problems
according to researches Your chances of
heart attack go up by 20% if you are 60 or older when you start them or if you became menopausal more than 10 years ago.
as you have not mentioned from how long have you started HRT post
menopause ,and you had history of small strokes
i would suggest you to go for a
ECG
2D echo( to rule out any problem to blood supply of heart),a s many times
angina does not presents as frank
chest pain but it presents as a chest dis comfort
as you say it precedes hot flashes again menopause and hrt withdrawal can be a cause of it ,hot flashes post menopause are very common and thats why HRT is prescribed to the patient
as off now go for ecg and 2d echo if that is normal ,HRT therapy should be discussed with your gynecologist .
