Objective — to identify predictors of systolic myocardial dysfunction of the left ventricle in pregnant women with preeclampsia on the background of normal ejection fraction and preserved cardiac pump function according to the speckle tracking echocardiography. Material and methods. 100 pregnant women with preeclampsia with gestational age 29 to 40 weeks are divided into three groups:1st group — 50 patients without arterial hypertension in anamnesis; group 2 — 40 patients with arterial hypertension in anamnesis; 3rd group — 10 women with preeclampsia and daily proteinuria from 3 to 5 g/L. All the patients echocardiography with the evaluation of the function of the cardiomyocytes by the method of speckle-tracking was performed on ultrasound scanners Aplio 500 and Aplio Artida, «Toshiba». Results. Ejection fraction of the left ventricle and the heart’s pumping function in all 3 groups did not differ significantly, while the values of longitudinal, radial and circumferential strain differed within groups and the lowest indices characterized the global longitudinal deformation. Conclusions. It is not enough to focus only on ejection fraction and cardiac output/cardiac index in the assessment of left ventricular function in pregnant women with preeclampsia. The study of myocardial using speckle tracking echocardiography may help to detect subclinical left ventricular dysfunction in patients with preeclampsia.
