RESUMO

OBJECTIVE: Cardiovascular disease (CVD) is the number one cause of death in women and defining its risk factors is necessary to reduce its prevalence. A history of preeclampsia is shown to be associated with hypertension and alterations in left ventricular (LV) diastolic function parameters. Because of overlapping mechanisms between preeclampsia and spontaneous preterm birth (SPTB), our most recent study investigated the association between SPTB and hypertension, and found an almost 2 times higher prevalence of hypertension after SPTB. No previous studies have focused on the association between SPTB and LV diastolic function. The aim of this study is to investigate LV diastolic function as potential early parameter of CVD in women with a history of SPTB. STUDY DESIGN: We included cases with a history of SPTB between 22 and 37 weeks and controls who had a term birth. Women with hypertensive disorders or gestational diabetes in any of their pregnancies, were excluded. Both groups underwent cardiovascular risk assessment and transthoracic echocardiography 9 to 16 years after pregnancy. Echocardiographic measures were adjusted using a linear regression analysis accounting for hypertension and other risk factors known to be associated with CVD. A subgroup analysis was performed based on hypertension at follow-up. RESULTS: A total of 94 cases and 94 controls were included, on average 13 years after pregnancy. There were no significant differences in LV diastolic function parameters. Women with a history of SPTB and diagnosed hypertension at follow-up, showed significant higher late diastolic mitral flow velocity, lower e'septal velocity and higher E/e'ratio, compared to women with a history of SPTB without hypertension, although within normal ranges. CONCLUSIONS: When a history of SPTB is accompanied by hypertension at follow-up, significant changes in LV diastolic function were seen. Therefore, hypertension is the central factor in preventive screening methods, and transthoracic echocardiography has no additional value at this follow-up duration.

RESUMO

OBJECTIVE: To investigate whether a history of spontaneous preterm birth (SPTB) predisposes to maternal hypertension. DESIGN: Retrospective case-control study. SETTING: Two affiliated university medical hospitals in Amsterdam, the Netherlands. POPULATION: We included 350 women with a history of SPTB between 22 and 36+6  weeks and 166 women with a history of a term birth. Women with pregnancy complications that are known to be associated with cardiovascular disease were excluded. METHODS: Both groups underwent cardiovascular risk assessment 9-16 years after pregnancy. We performed a subgroup analysis based upon the severity of SPTB. MAIN OUTCOME MEASURES: Hypertension. Secondary outcomes - metabolic syndrome, mean blood pressure, anthropometrics, blood and urine sampling, Framingham Risk Score and Systematic Coronary Risk Evaluation. RESULTS: A history of SPTB was significantly associated with hypertension; adjusted odds ratio 1.60 (95% confidence interval 1.04-2.46, p = 0.033). Abdominal obesity was more often diagnosed after SPTB (n = 163, 46.6% versus n = 54, 32.5%, p = 0.003) and was more pronounced with more severe preterm birth (p = 0.002). CONCLUSIONS: The presence of hypertension 9-16 years after pregnancy was statistically significantly higher among women with a history of SPTB than among women with a history of uncomplicated term birth. Women with a history of SPTB were more often diagnosed with abdominal obesity, especially those with a history of extreme preterm birth.
