The effects of left ventricular geometry and hypertrophy on the diastolic filling indices in hypertension

الملخص EN

Objectives : the aim of this study is to show the effects of left ventricular hypertrophy and geometric patterns on the left ventricular diastolic function in patients with essential hypertension.

In addition, it’s aimed to identify whether the diastolic dysfunction is associated with systolic dysfunction.

Finally, to determine the occurrence of the diastolic dysfunction in hypertensive patients with normal left ventricular mass.

Patients and Methods : 135 subjects with essential hypertension of either sex attending echo unit were subjected to medical history, clinical examination, physical measurements, ECG, Mmode and Doppler echocardiography.

They were classified as 43 treated hypertensives, and 92 untreated hypertensive patients.

In addition to 32 healthy subjects served as control group.

Results : The results of this study showed that untreated stage II hypertensive patients have more changes in left ventricular mass and geometry and, hence, a higher percentage of diastolic dysfunction.

There was a small percentage of patients having diastolic dysfunction despite they were without LVH.

In addition, Doppler echocardiographic examination showed that hypertensive patients with left ventricular diastolic dysfunction were having a normal left ventricular systolic function.

Conclusion : Left ventricular hypertrophy and geometric changes have an obvious effects on the Left ventricular diastolic function especially in untreated stage II hypertensive patients.
