Abstract:
Background : The present study was undertaken because there is only limited information available regarding the effect of menopause over heart rate recovery and lipid profile.
Aim: Aim of the study was to calculate heart rate recovery and to estimate lipid profile and to compare the parameters between pre and post menopausal women.
Materials and Methods: The present cross-sectional study was conducted in 120 healthy non athletic female volunteers consisted of 60 premenopausal women between the age group of 40-45 years and 60 post-menopausal women between the age group of 45-50 years. All the 120 subjects underwent a modified Bruce exercise protocol testing on a treadmill after taking blood sample for lipid profile. Heart rate was recorded during the exercise at each stage and also during the recovery period (1 minute, 2 minute and 5 minutes after the exercise)
Result: The heart rate recovery was lower in the post-menopausal group when compared to premenopausal women and the difference was statistically significant (P<.0001). The mean of the total cholesterol, LDL, triglycerides and VLDL were comparatively higher in the post-menopausal group than that of the pre-menopausal group and the difference was statistically significant (P<.0001).
Conclusion: Our data suggested that post menopausal women had delayed heart rate recovery and increased total cholesterol, LDL, VLDL, triglycerides and reduced HDL when compared to premenopausal women.
