Abstract

Objectives: Abnormalities in left ventricular (LV) diastolic filling have been reported in hypertensive patients. This study was designed to compare LV diastolic filling between individuals with high normal blood pressure (HNBP) and optimal blood pressure (OBP). Subjects and Design: From a survey of 219 young male individuals (age 21 ± 0.1 years), two groups were selected according to their BP (group A: systolic BP [SBP] 120 mmHg and diastolic BP [DBP] 80 mmHg, n = 23 and group B: SBP 030 to 139 mmHg and/or DBP 85 to 89 mmHg, n = 21). subjects' habits, anthropometric characteristics, LV structure and systolic and diastolic function were compared. Results: No differences were detected between the two groups in habits, systolic function or early diastole. LV mass index (LVMI) was higher in group B (103.6 ± 4.58 g/m2 versus 90.49 ± 3.27 g/m2 in group A, P <0.05), though the values were not high enough to indicate LV hypertrophy. The pattern of LV late filling was different between the two groups. The peak late diastolic flow velocity (A) was 0.45 ± 0.02 m/s in group B and 0.52 ± 0.03 m/s in group A (P <0.05). The early peak velocity (E): A ratio was 1.82 ± 0.08 in group A and 1.59 ± 0.08 in group B (P <0.05). The early filling fraction also demonstrated a significant shift to more prominent late diastolic filling in group B (0.68 ± 0.01% versus 0.73 ± 0.01% in group A, P <0.05). This pattern in LV filling did not correlate to inheritance, age, sex, heart rate, habits or body mass index. Conclusions: This shift in filling pattern to a late flow in young men with HNBP seemed to be an early indicator of an increased dependence of LV filling on atrial contraction and may reflect an impairment in LV relaxation.
