The Effect of Menstrual Cycle on the Results of Treadmill Exercise Test With High Sensitive Cardiac Troponin Levels After Exercise in Women
Study Overview
Status
Intervention / Treatment
Detailed Description
Estrogen is known to have direct vasodilatory effects on coronary arteries. Early and late follicular phases of the menstrual cycle in premenopausal women are characterized by low and high estrogen levels, respectively. The Early Follicular Phase starts on the first day of the menstrual cycle and ends when oestradiol begins to increase. It is characterised by increasing LH and FSH and constant low levels of oestradiol. The late follicular phase starts with the increase in oestradiol and ends at its preovulatory peak. Premenopausal women (between the ages of 18-40), who apply to the cardiology outpatient clinics of Göztepe City Hospital with typical/atypical chest pain, and an indication for exercise treadmill test (ETT) will be included in the study. ETT will be performed in the early and late follicular phases of the menstrual cycle, separately.
Forty (40) patients who meet these conditions will be included in the study.
The menstrual cycle of the patient will be questioned in the screening interview. Premenopausal female patients between the ages of 18-40 who still have a regular menstrual cycles will be included in the study. Hormone levels including Estradiol III, follicle stimulating hormone (FSH), luteinizing hormone (LH), progesterone (Elecsys) will be measured to confirm the menstrual cycle before each ETT. ETT will be performed in the early and late follicular phases of the menstrual cycle, separately. Cardiac high sensitive troponin I (hs cTnI) (Roche) will be measured before and after ETT.
Primary end point will the ST/HR (heart rate) index (μV/bpm) in ETT. The ST/HR index (μV/bpm) is automatically generated by the General Electronic GE Healthcare T2100-ST Treadmill & CASE 6.73 Stress Test System.
The secondary endpoints will be the change in hs cTnI between the before and after ETT, maximal exercise capacity (METs score), ST/HR slope (μV/bpm), maximal horizontal or down slope ST segment depression (mm) with exercise. Secondary end points other than cTnI are automatically generated by the General Electronic GE Healthcare T2100-ST Treadmill & CASE 6.73 Stress Test System.
The null hypothesis is that there is no difference between in the ST/HR index (μV/bpm) between the menstrual phases. The power is calculated to prove the alternative hypothesis in which there is a 50 % difference between the ETT ST/HR index (μV/bpm). In a paired study sample, with type I error of 5 % and type II error of 20 %, the sample size is calculated as 34 patients.

Design Details
Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Exercise test results will be grouped based on the menstrual cycle.
Positive exercise treadmill tests will be repeated at a different phase of menstrual cycle in premenopausal women (early versus late follicular phase).
|
Routinely ordered exercise treadmill test results will be reviewed in premenopausal women.
ETT results and change in hs cTnI levels will be compared between the early and late follicular phases of menstrual cycle.
