0546: Three dimensional speckle tracking imaging: a promising tool in the assessment of hypertensive heart disease

Introduction 3D speckle tracking imaging (3D-STI) is a new technique in the assessment of several heart diseases. We aim to delineate the effect of arterial hypertension (HTN) on left ventricle (LV) through a STI study. Patients and Methods We studied 31 HTN patients and 30 age-matched healthy volunteers. The main exclusion criteria were atrial fibrillation, coronary artery disease, severe valvular heart diseases and liver or kidney dysfunction. Therefore, each subject underwent an echocardiogram with 3D-STI and serum NTproBNP was determined. Results Among HTN patients, near 55% were women. Systolic and diastolic blood pressure were 149,6±17 and 89±10mmHg (vs. 119,7±7 and 77,6±6mmHg; p 2 which was significantly higher than healthy subjects (75±18g/m 2 ; p Only 6 HTN patients had eccentric LV hypertrophy. NTproBNP was greater in HTN patients (31,3 vs. 13 ng/ml; p=0,01). 3D LV peak longitudinal strain (3D-PSLG) was lower in HTN group (–14±2 vs. –19±2; p Conclusion: 3D-STI is a useful technique in the assessment of hypertensive heart disease. This study highlighted the relation between LV concentric geometry (RWT) and PSLG.
