Doppler echocardiographic evaluation of the spectrum of left ventricular diastolic dysfunction in essential hypertension.
Left ventricular topography and diastolic and systolic functions were studied in 41 patients with essential hypertension (group 1) and 33 age-matched normal adults (group 2) by Doppler echocardiography. In group 1 54% had LV concentric hypertrophy, 19% had combined concentric hypertrophy and eccentric remodeling, and 27% had concentric remodeling. LV systolic function was within the normal range. In concentric LV remodeling, the EDV was significantly decreased (compared with group 2) (84 +/- 15 vs 130 +/- 38 ml, p < 0.05), whereas the NPFR was normal (2.89 +/- 0.65 vs 3.22 +/- 0.83 sec-1, p = NS). In concentric hypertrophy, LV end-diastolic and end-systolic volumes were normal, but the NPFR was decreased (2.04 +/- 0.59 sec-1). Patients with concentric hypertrophy and eccentric remodeling had the largest end-diastolic (140 +/- 48 ml) and end-systolic (62 +/- 32 ml) volumes and the lowest NPFR (1.67 +/- 0.69 sec-1). The LVMI inversely correlated with the NPFR (r = -0.89, p < 0.0001). Thus LV concentric hypertrophy with or without concentric or eccentric remodeling is seen in patients with systemic hypertension. A decrease in peak filling occurs early in the evolution of hypertensive heart disease and is observed even when systolic performance is still normal.
