patients

We examined 62 masculine patients. Middle age was 52,3 yearrs ranging from 27 do
64.On the basis of the anamnesis medical treatment length of hypertension was
from 1,2 to 8 years,middale value has been 4,2 years.
We used the following non invasive methods: electrocardiogram,x-ray of
heart,phonocardiogram,carotidogram,apexcardiogram and one and two dimensional
echo and radionuclide equilibrium ventriculography.Hemodynamic tests were done
in 21 patients.Out of these testings we have used ejection fraction (RF) and
left ventricular enddiastolic pressure (LVEDP).
The patients were divided in three groups.Loading was done in 3o patients.The
division of the patients into three groups is practical due to the folloqing
reasons:
The first group, consists of patients with normal electrocardiogram,X-ray of
heart is normal as well,EF and VcF,as well as PEP and LVET ration (Weissler’s
index) are normal too.The early conformation of the arterialhypertension is easy
enlargement of left ventricular mass.
The second group had normal X-ray of the heart,ECG have shown the hypertrophy of
the left ventricle.Weissler,s index,EF and VcF were in the normal limits.The
function of the heart as a pump is good,but echo have shown significant
enlargement of the left ventricular mass.At this stage there exist changes in
the diastolic complex of the left ventricle and the consecutive left ventricular
pressure increase.The diastolic changes have been reflected with regard to waves
enalargement and the heights (H) in apexcardiogram.There exists a good
correlation between a/H and LVEDP relations
In the third group of patients there existe significant enlargement of the left
ventricular massThe role of the heart as the pump is reduced and pathological
values such as:EF,VcF,PEP/LVET relation in the carotidogram and a/H in the
apexcatdiogram have been suggested to this.
