Abstract
Objective — to determine and evaluate ultrasonic parameters of the heart in patients with essential hypertension (EH), complicated with hemorrhagic stroke (HS), after an early recovery period. Methods and subjects. There were formed 3 groups of people: the main group included 107 patients (56 women and 51 men, mean age 54.0 ± 9.5 years old) who had undergone HS as a complication of EH 6 months previously; the comparison group comprised 104 persons (54 women and 50 men, mean age 53.7 ± 8.9 years old); the control group consisted of 19 persons (10 women and 9 men, mean age 52.5 ± 5.1 years old). Groups were matched according to key indicators. All the abovementioned people underwent transthoracic echocardiography and doppler sonography of the heart in onedimensional (M) and twodimensional (B) regimens with detection of the main ultrasonic parameters of the heart. Results. The ultrasonic parameters of the heart in the main group were the following ones (М ± s): aortic valve size 1.875 ± 0.154 cm; ascending aorta diameter 3.377 ± 0.395 cm; left atrium (LA) dimension in systole 3.402 ± 0.484 cm; right ventricle dimension in diastole 2.891 ± 0.543 cm; interventricular septum (IVS) thickness 1.132 ± 0.130 cm; left ventricle (LV) posterior wall thickness 1.132 ± 0.139 cm; LV ejection fraction 62.531 ± 2.994 %; LV enddiastolic size 4.668 ± 0.436 cm; LV endsystolic size 2.750 ± 0.402 cm; LV enddiastolic volume 124.323 ± 27.090 ml; LV endsystolic volume 47.161 ± 14.466 ml; LV stroke volume 77.161 ± 15.358 ml; LV diastolic function (E/A ratio) 1.025 ± 0.146. Aortic valve size and LV ejection fraction in the main group were significantly (p < 0.05) smaller in comparison against the control group; LA dimension in systole, LV ejection fraction and IVS thickness were significantly smaller against the comparison w group, and LV endsystolic volume and E/A ratio were significantly greater against the comparison group. The characteristics of the LV geometry in the main group in men and women, respectively: LV volume index was 66.69 ± 10.40 and 64.30 ± 14.24 ml/m2; LV mass index was 111.34 ± 20.16 g/m2 and 96.48 ± 19.63 g/m2; LV relative wall thickness was 0.47 ± 0.06 and 0.51 ± 0.07. Conclusions. In patients with EH, who suffered HS more than 6 months before and recovered up to 50 — 100 points according to Barthel scale, compared with patients with EH stage II, LA dimension in systole, LV ejection fraction and IVS thickness are significantly smaller, the E/A ratio and LV endsystolic volume are significantly greater, that indicates the liability to LV systolic dysfunction in this category of patients compared to the relevant parameters in the patients without occurrence of HS. The mean arithmetical values of LV mass index, LV volume index and relative wall thickness signify the prevalence of concentric remodeling of heart in men and concentric hypertrophy of mild degree in women, although most men (57 %) had the LV mass index value > 115 g/m2, and most women (55 %) ≤ 95 g/m2.
