[Comparison of dysrhythmias in women with hypertension in the period of premenopause and in late fertile period with altered hormonal background in dependence on the variant of left ventricular modeling].

We carried out 24 hour Holter ECG monitoring in 106 women with hypertension in the period of premenopause and in late fertile period with altered hormonal background. Comparative analysis of character and structure of dysrhythmias showed that supraventricular premature beats including rapid and allorhythmic extrasystoles were more often registered among premenopausal women than among patients in fertile period. Same tendencies took place concerning frequency of ventricular rhythm disturbances (in most cases I grade II-IV ventricular extrasystoles). Comparative analysis of dysrhythmias in premenopausal and fertile hypertensive women with normal left ventricular geometry and with hypertrophic type of remodeling showed that both supraventricular and ventricular rhythm disturbances were significantly more often registered in hypertrophic variants of left ventricular remodeling, especially in premenopausal women.

[The process of remodeling of left chambers of the heart and dysfunction of endothelium of peripheral vessels in hypertensive premenopausal women].

Results of ultrasound study of 230 premenopausal women with I-II stage essential hypertension (EH) in relation to functional state of endothelium of peripheral arteries are presented. Endothelial dysfunction in hypertensive premenopausal women can be one of factors contributing to remodeling of left cardiac chamber. Women with EH and endothelial dysfunction compared with those with conserved vascular endothelial function more often had hypertrophic variants of left ventricular myocardial remodeling (mostly of concentric type). Premenopausal women with EH had diastolic dysfunction of the left ventricle with impairment of both its rigidity and active relaxation, more pronounced in the presence of dysfunction of endothelium of peripheral vessels.
