This prospective study was designed to investigate the effects of hormone
replacement therapy (HRT) on systolic and diastolic functions. Twenty-eight
non-smoking, healthy postmenopausal women who had not received any kind of
HRT for at least three years within the onset of menopause were included in
the study. All patients received 0.625 mg conjugated oestrogens and 2.5 mg
medroxyprogesterone acetate as daily HRT regimen. Their basic systolic and
diastolic functions were investigated echocardiographically using standard
positions and windows before and 6 months after initiation of HRT. The
means of age, weight and length of postmenopausal period were 49.3 +/- 5.8
years, 63.5 +/- 8.7 kg and 46.3 +/- 7.1 months, respectively. Heart rate
and systolic and diastolic pressures were similar during the pre- and
post-treatment periods. After 6 months of HRT, the mean left ventricular
end-systolic and end-diastolic volumes were decreased significantly (71.3
+/- 16.4 versus 56.3 +/- 22.8 ml, 144.5 +/- 26.1 versus 111.7 +/- 24.0 ml,
respectively, P < 0.05). Left ventricular ejection fraction was
increased (45.1 +/- 6.2% versus 54.8 +/- 4.1%, P < 0.05). Improvement in
diastolic function was significant compared with the pretreatment period
(E/A 0.90 +/- 0.2 versus 1.10 +/- 0.4, deceleration time 238 +/- 36.8
versus 201 +/- 24.2 ms, respectively, P < 0.05). Based on our
preliminary results, we conclude that besides the known favourable effects
on women's lives, HRT may also improve cardiac performance and age-related
dysfunctions. The present results further suggest that oestrogens exert
many direct effects on the cardiovascular system, other than the metabolic
changes related to lipoproteins.
