Rapid left ventricular filling in untreated hypertensive subjects with or without left ventricular hypertrophy.

In this study, independent contribution of age, HR, BMI, casual and ambulatory blood pressure, LVM and LVEF in evaluating diastolic filling have been investigated in 34 never-treated hypertensive patients and in 15 healthy normotensive subjects. All the subjects were free from coronary artery disease, valvular disease, heart failure, renal disease and psychiatric problems. All the hypertensive subjects (never treated) were subgrouped according to presence or absence of LVH. The PFR decreased significantly and tPFR increased significantly in hypertensive patients in comparison with normotensive subjects and they did not change in the presence vs absence of LVH. The PFR was inversely correlated with BMI, age, 24-h mean SBP and with 24-h DBP. In multiple regression analysis, PFR decreased with BMI, age, 24-h mean SBP and DBP but not with LVMI. These results suggest that BMI, age and 24-h mean blood pressure were the major determinants of PFR abnormalities in hypertensive patients.
