Echocardiographic findings in essential hypertensive patients influence of period on left ventricular hypertrophy development

الملخص EN

Aim of study: This work was done to assess the effect of the duration of arterial hypertension (AHT) on the progression of left ventricular hypertrophy (LVH).

An echocardiographic study on left ventricular dysfunctions in a group of hypertensive patients in 22 May Hospital in Aden Governorate.

Method:Echocardiographic study for sixty-one hypertensive patients was done in a cross sectional manner which included 61 hypertensive patients.

left ventricular structure and function were studied with B - mode, M- mode and Doppler echocardiography.

Results :47.6% of the study group were with history of AHT of more than 5 years’ duration, while 39.3% were having AHT of 1-4 years’ duration.

however only 13.1 of them were hypertensive for less than 1-year duration.

Mild (grade I) left ventricular impaired relaxation occurred in more half of the cases (57.4).

However only 2 (3.3) had sever (grade III) left ventricular impaired relaxation.

There was statistically significant correlation between duration of AHT and left ventricular dimension in diastole (LVEDD) (-0.22/0.049), and less significant with left ventricular posterior wall (PLVWD), (P value 0.17/0.09) while there were no statistically significant correlations with inter ventricular septum in diastole (IVSD), (P value 0.048/0.36) as well as left ventricular ejection fraction (EF), (P value 0.18/0.08) and short fraction (SF), (P value 0.114/ 0.193).

conclusion: Duration of AHT alone has no significant role in progression of left ventricular hypertrophy.

Other factor like: age, sex, severity of AHT and adherence to treatment should be take into consideration of further studied need to follow these parameters and another consistent echo cardiac – evaluation of LVH like left ventricular mass indexed to body surface area is mandatory.
