Objective:
To evaluate the association between estrogen (E) exposure and deficiency and cardiovascular disease (CVD) risk among women with primary ovarian insufficiency (POI).
Design:
Cross-sectional study conducted between 1996 and 2016.
Setting:
Tertiary referral centers.
Patient(S):
A total of 385 women with POI, defined by amenorrhea and FSH levels ≥40 IU/L before 40 years of age, were recruited.
Intervention(S):
None.
Main Outcome Measure(S):
Women underwent a standardized intake questionnaire including data on menstrual cyclicity. Lifetime E exposure and E-free period were assessed. Serum was analyzed for endocrine and CVD profiles. The Framingham 30-year risk of CVD was calculated.
Result(S):
Lifetime E exposure (mean ± SD) was 19.3 ± 7.0 years, E-free period was 3.1 ± 4.1 years, and age at screening was 34.8 ± 7.4 years. In multivariate models E-free interval associated positively with estimated risk of hard and general CVD events (β 0.18 [95% confidence interval 0.08, 0.29]; 0.20 [0.05, 0.35], respectively), and lifetime E exposure associated negatively with estimated risk of hard and general CVD events (-0.15 [-0.24, -0.05]; -0.16 [-0.29, -0.03], respectively), as well as low density lipoprotein cholesterol (-0.03 [-0.06, 0.00]) and non-high density lipoprotein cholesterol (-0.04 [-0.07, 0.00]).
Conclusion(S):
Prolonged E deprivation is associated with an increased estimated risk of CVD, whereas prolonged E exposure is associated with a reduced estimated risk. These results support the policy of early and continued use of E replacement therapy in women with POI.

Overview of the Cardiovascular System
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
