The aims of the thesis were to investigate the impact of pregnancy blood pressure, a
current diagnosis of hypertension and blood pressure levels on neurohumoral, cardiovascular
and metabolic status in postmenopausal women and thus to explore possible
contributing mechanisms to the increased cardiovascular risk following hypertensive
pregnancies.
In this follow-up study after hypertensive- and normotensive pregnancies, 105 women
were evaluated with the following methods: microneurography; office-, ambulatory-
and central blood pressure measurements; anthropometric measurements; pulse
wave velocity and augmentation index; carotid intima-media thickness; cardiovascular
response to mental stress test and evaluation of perceived stress; echocardiography
and laboratory analyses regarding metabolic and neurohumoral values. Another 160
women responded to a questionnaire regarding previous and present health.
Women with previous hypertensive pregnancies had an increased prevalence of a diagnosis
of hypertension, increased pulse wave velocity and affected metabolic parameters
compared to women with previous normotensive pregnancies. These findings may partly explain the increased cardiovascular risk following hypertensive pregnancies.
The sympathetic activity was only increased in women with previous hypertensive
pregnancies and present hypertension. High self-reported perceived stress was
associated with increased waist circumference which, in turn is related to an increased
cardiovascular risk. Higher blood pressure levels were related to early signs of left
ventricular diastolic dysfunction, emphasizing the importance of rigorous blood pressure
control.
Our study contributes with unique knowledge regarding women’s health many years
after hypertensive and normotensive pregnancies. A diagnosis of present hypertension
seems to be of major importance for the increased cardiovascular risk after hypertensive
pregnancies, why maintenance of normotension is essential for women with previous hypertension pregnancies in order to retain cardiovascular health after menopause
