The study population consists of premenopausal women who applied to the outpatient clinic with chest pain. ETT is ordered as a routine diagnostic workup. Two ETTs are performed on each participant. The early follicular phase ETT is planned on the 3rd day of menstrual bleeding, while the menstrual bleeding continues. The late follicular phase ETT is planned on the 3rd day after the menstrual bleeding ends. Hormone levels are measured before each ETT to ascertain the phase of the menstrual cycle.
