[Echocardiographic evaluation of left ventricular function in patients with arterial hypertension and normal left ventricular mass index].
Data about disturbances of the diastolic function of the left ventricle (LV) are well known in literature and registered even in the limited form of hypertension i.e. before the occurrence of myocardial hypertrophy. The aim of this work was to check this hypothesis in patients with arterial hypertension and normal LV mass index. The total number of examined patients was 144. The control group consisted of 30 patients, while the number of hypertensive patients in the other group was 114. The following parameters were observed: blood pressure, heart rate, systolic and diastolic dimensions of LV, wall thickness, left ventricular mass index, wall stress, endsystolic and enddiastolic volume index, cardiac index, ejection fraction, shortening fraction, velocity peak of early and late diastolic filling and their mutual relationship, integral of speed-time of early and late diastolic pressure, as well as the index of early and late filling. A significant difference was found in the size of LV mass index, wall stress, velocity peak of early diastolic filling and the relationship of velocity peak of early and late filling. It should be noted that the values of the observed parameters were in normal ranges, but those in the group of hypertensive patients were closer to pathological values.


CONCLUSIONS
Microstructural changes of LV myocard mass can be registered in hypertensive patients before the significant enlargement of LV mass index. Diastolic disfunction of the left ventricle precedes myocardial hypertrophy.
