Abstract/OtherAbstract:
BACKGROUND: The association between nondipping profile and adverse cardiovascular outcome is still controversial. Tissue Doppler imaging (TDI), a new and useful addition to standard echocardiographic imaging techniques, permits a quantitative assessment of both global and regional function and timing of myocardial velocities. In this study, we aimed to assess whether a reduced nocturnal fall in blood pressure (BP) in orderly treated hypertensive patients with satisfactory BP control is related to more prominent structural and functional alterations of the ventricles. METHOD AND RESULTS: Sixty-nine hypertensive patients with adequate BP control were divided into two groups with respect to ambulatory BP profiles as dippers and nondippers. In addition to conventional echocardiographic parameters, in septal and lateral segments of left ventricle and free wall of right ventricle, peak systolic velocity (Sm), early (Em), and late (Am) diastolic velocities, isovolumic contraction time (ICTm), isovolumic relaxation time (IRTm), and ejection times (ETm) were measured, and modified myocardial performance index (MPIm) was calculated. Left ventricular (LV) and atrial dimensions, ejection fraction, transmitral early to late diastolic flow ratio, LV mass index, and LV hypertrophy ratio did not differ between groups. Both regional and mean LV Sm, Em/Am, MPIm and right ventricular Sm and MPIm were similar in both groups. CONCLUSION: In treated hypertensive patients with satisfactory BP control, there was no significant difference in cardiac structural and functional abnormalities among dipper and nondipper subjects.
