Key result
Pregnancy loss shows no association with midlife cardiac structure, function, or carotid thickness.
Why the study?
Cardiovascular disease is more common in women with pregnancy complications such as spontaneous pregnancy loss, but the association with cardiac or vascular remodelling in later life is unclear.
Does self-reported pregnancy loss identify women at risk of adverse cardiac or vascular remodelling in later life?
Population
2,519 women aged 40-69 years from UK Biobank Imaging Enhancement Study without pre-existing cardiovascular disease
Comparison
Women with self-reported spontaneous pregnancy loss vs women with pregnancies but no loss and nulligravid women
Design
Cross-sectional study using cardiac MRI and carotid ultrasound imaging

No remodelling differences seen with self-reported pregnancy loss; leaves open alternative mechanisms or unmeasured loss features for targeted research.

Does self-reported pregnancy loss identify women at risk of adverse cardiac or vascular remodelling in later life?
Self-reported pregnancy loss is not associated with adverse cardiac or carotid structural changes in later life, suggesting that the increased cardiovascular risk in these women operates through other disease mechanisms.
Elmahi et al. (2019) conducted a cross-sectional in Cardiovascular risk (n=2,519). Self-reported pregnancy loss vs. No history of pregnancy loss or nulligravid was evaluated on Cardiac structure, cardiac function, and carotid intima-media thickness. Self-reported pregnancy loss was not associated with significant differences in cardiac structure, cardiac function, or carotid intima-media thickness in later life.
