| description | <p><strong>Objective</p></strong>
To investigate the association between postpartum haemorrhage (PPH) and subsequent cardiovascular disease.
<p><strong>
Design</p></strong>
Population-based retrospective cohort study, using record linkage between Aberdeen Maternity and Neonatal Databank (AMND) and Scottish healthcare data sets.
<p><strong>
Setting </p></strong>
Grampian region, Scotland
<p><strong>
Population or Sample</p></strong>
A cohort of 70 904 women who gave birth after 24 weeks of gestation in the period 1986–2016.
<p><strong>
Methods</p></strong>
We used extended Cox regression models to investigate the association between having had one or more occurrences of PPH in any (first or subsequent) births (exposure) and subsequent cardiovascular disease, adjusted for sociodemographic, medical, and pregnancy and birth-related factors.
<p><strong>
Main outcome measures</p></strong>
Cardiovascular disease identified from the prescription of selected cardiovascular medications, hospital discharge records or death from cardiovascular disease.
<p><strong>
Results</p></strong>
In our cohort of 70 904 women (with 124 795 birth records), 25 177 women (36%) had at least one PPH. Compared with not having a PPH, having at least one PPH was associated with an increased risk of developing cardiovascular disease, as defined above, in the first year after birth (adjusted hazard ratio, aHR 1.96; 95% confidence interval, 95% CI 1.51–2.53; p < 0.001). The association was attenuated over time, but strong evidence of increased risk remained at 2–5 years (aHR 1.19, 95% CI 1.11–1.30, P < 0.001) and at 6–15 years after giving birth (aHR 1.17, 95% CI 1.05–1.30, p = 0.005).
<p><strong>
Conclusions</p></strong>
Compared with women who have never had a PPH, women who have had at least one episode of PPH are twice as likely to develop cardiovascular disease in the first year after birth, and some increased risk persists for up to 15 years.
