- W2333218106 abstract "To study the significance of left ventricular (LV) diastolic filling in elder patients with hypertension (HT), cardiac blood pool imagings with Tc-99m were obtained at rest in 17 normal subjects and 28 patients with systemic hypertension. The patients with hypertension did not show any evidence of coronary heart disease, renal insufficiency or other disease. Moreover, they showed normal LV ejection fraction (LVEF) and normal LV wall motion. They were divided into 4 groups: 1) normal-young (less than 60 years old, n = 10), 2) normal-old (greater than or equal to 65 years old, n = 7), 3) HT-young (less than 60 years old, n = 15), 4) HT-old (greater than or equal to 65 years old, n = 13). From the LV volume curve and its first differentiation curve, LVEF, mean first third ejection rate (ERm) and peak ejection rate (PER) were obtained as indices of the LV systolic function, and LV diastolic filling rate during the first third of diastole (FRm) and peak filling rate (PFR) were obtained as indices of LV diastolic function. All indices of LV systolic function were similar in all groups. In contrast, LV diastolic indices (FRm and PFR) of older groups were significantly lower than those of young groups both in HT and normal. Also, LV diastolic indices in HT groups decreased significantly in comparison with normal groups of the same age group. Among diastolic indices, FRm could distinguish patients with HT from normal subjects of the same age group more accurately than PFR.(ABSTRACT TRUNCATED AT 250 WORDS)" @default.
