To investigate maternal cardiovascular function in women with a previous pregnancy complicated by early onset pre-eclampsia.
Retrospective case-control study of non-pregnant women with a previous singleton pregnancy complicated by pre-eclampsia delivered < 34 weeks (n = 15) and women with a previous uncomplicated pregnancy (n = 15). Women with chronic hypertension or other medical complications were excluded. Maternal echocardiography, ambulatory blood pressure monitoring, carotid intima-media thickness (IMT) measurements and radial artery pulse waveform analysis were performed.
The mean interval between delivery and examination was 849 ± 226 days in cases and 895 ± 224 days in controls (p = 0.58). Diastolic blood pressure, but not systolic or mean pressure, was higher in formerly pre-eclamptic women compared to controls (p < 0.05). On bidimensional echocardiography, left atrial diameter was significantly lower in this group (p < 0.05), while other measurements, cardiac output and ejection fraction did not differ. Indices of ventricular diastolic function measured with tissue Doppler imaging such as the Em/Am and E/Em ratios were significantly worse in cases (p < 0.05). Pulse wave velocity did not differ between groups, while IMT was higher in former pre-eclamptics (p < 0.05).
In normotensive non-pregnant women with a previous pregnancy complicated by early onset pre-eclampsia, as compared to controls, there is decreased diastolic maternal cardiac function, a higher diastolic blood pressure, and increased IMT. These findings may represent risk factors for cardiovascular complications in later life.
