Aim: To study variants of the course of chronic hypertension in pregnant women and determination of factors predisposing to a persistent rise of arterial pressure (AP) in pregnancy.
Material and methods: A total of 50 pregnant women were examined (heart rhythm variability and psychological testing) who had AP 140/90 mm Hg and higher as shown by measurements at three outpatient check-ups. After delivery the patients were retrospectively devided into two groups. Twenty-seven group 1 women had frequent rises of AP to 140/90 and higher throughout pregnancy; twenty-three women of group 2 had high AP only at early terms of pregnancy, later they became normotensive without use of hypotensive drugs. 24-h AP monitoring was made in 29 patients. By its results, two subgroups were identified: 11 patients with essential hypertension and 18 women with neurocirculatory dystonia by hypertensive type.
Results: In group 1 there was an early fall of cardiac performance, higher values of SMIP test according to scales 2 (pessimism), 3 (emotional lability), 4 (impetuosity) and 7 (anxiety).
Conclusion: The analysis of 24-h AP profiles revealed more persistent and significant rise of AP in patients with essential hypertension than in those with neurocirculatory dystonia. They also demonstrated high AP variability correlating with a risk of cardiovascular diseases.
