Abstract
BACKGROUND: As a hypertensive disorder of pregnancy, preeclampsia is associated with increased cardiovascular morbidity and mortality later in life. Since early signs of myocardial affection could indicate a higher risk of future cardiovascular disease manifestations, we investigated whether women with prior preeclampsia have a higher prevalence of left ventricular hypertrophy compared with women from the general population and to what extent chronic hypertension affects any potential difference.
METHODS: In a cohort study, women aged 40 to 55 years with prior preeclampsia were compared with age- and parity-matched women from the general population. They underwent a research cardiac computed tomography, and the primary outcome was left ventricular hypertrophy, defined as a left ventricular mass index >30 g/m2.7.
RESULTS: In 679 women with prior preeclampsia and 672 controls (median age, 47 years), we found a higher prevalence of left ventricular hypertrophy (14.0% versus 6.4%) in the preeclampsia group with an odds ratio of 1.62, 95% CI (1.07-2.46), P=0.024, median of 15 years (range, 0-28) after pregnancy, after adjustment for cardiovascular risk factors, including chronic hypertension. Left ventricular hypertrophy was more frequent among women with preeclampsia with (26.2% versus 15.6%) and without (5.5% versus 2.4%) chronic hypertension, and a mediation analysis showed that chronic hypertension explained 22% of the association between preeclampsia and left ventricular hypertrophy.
CONCLUSIONS: Women with prior preeclampsia had a 2-fold higher prevalence of left ventricular hypertrophy compared with women from the general population, and preeclampsia was independently associated with left ventricular hypertrophy, regardless of the presence of cardiovascular risk factors, including chronic hypertension.
