Abstract：
BACKGROUND AND OBJECTIVE:Although impaired diastolic function is frequently found in systemic hypertension, the diagnosis of hypertensive heart disease (HHD) is based on the demonstration of left ventricular (LV) growth. The aim of the current work was to investigate the potential interactions between diastolic function and LV growth in patients with arterial hypertension. PATIENTS AND METHOD:One hundred and sixteen never-treated asymptomatic hypertensives underwent an echocardiographic evaluation. Classification of diastolic dysfunction (DD) was based on alterations in parameters assessing transmitral inflow, Doppler tissue imaging of mitral annular motion, and color M-mode propagation velocity. Classification of LV growth was based on alterations in left ventricular mass index and/or relative will thickness. RESULTS:Ninety-four patients (81%) exhibited DD and 22 (19%) exhibited normal diastolic function. Amongst patients with DD, 79 (84%) exhibited a pattern of impaired relaxation and 15 (16%) a pseudonormal pattern. The presence of LV growth was documented in 41% of patients without DD and 75% of patients with DD (p < 0.05). None of the studied patients exhibited echocardiographic signs of systolic dysfunction. CONCLUSIONS:These findings indicate that DD is an early and highly frequent cardiac alteration in arterial hypertension. In addition, our data show that one fifth of hypertensive patients have DD in the absence of LV growth. It is thus suggested that the diagnosis of HHD can not be further based exclusively on morphologic criteria and should include also the evaluation of alterations in LV filling.
