This study was performed to determine if diastolic dysfunction  is associated with LVH and inappropriate LVM.METHODS: one hundred  and twenty five uncomplicated hypertension from Isfahan Healthy Heart Program underwent two-dimensional echocardiography. Inappropriate LVM was defined as an LVM index greater than 88 g/m2 of body-surface area in women and greater than 102 g/m2  in men. LVH-defined septal and posterior wall thickness greater than 0/9 cm in women and greater than 1 cm in men, respectively. Echocardiographic parameters,  including early diastolic peak velocity (E)/late diastolic peak velocity (A), deceleration  time (DT), and E/early mitral annulus velocity (E′) were measured.RESULTS: the mean systolic and diastolic blood pressure at the patients’ admission day were 142.87 ± 18.12 and 88.45 ± 9.18 mmHg, respectively. Totally, 21.7% of subjects had inappropriate LV mass that moderate and severe abnormal LV mass was revealed in 5.6% and 5.6%, respectively. The mean of age and BMI was significantly higher in patients with moderate left ventricular hypertrophy (p < 0.05). Adjusted by age, gender, BMI, and systolic and diastolic blood pressures, both E/A ratio and deceleration time were higher in those with the severer ventricular hypertrophy. Subjects with severe showed significantly higher BMI 33. 7 ± 3.7 (p < 0.001). There was a slight difference between the grade of diastolic dysfunction  and the severity of inappropriate LV mass (p = 0.065). But no significant difference was found between E/A, E/E′, and deceleration time and the level of inappropriate LV mass (p > 0.05). Spearman’s Rank test was used to test the correlation between diastolic dysfunction and LV mass (p = 0.025).CONCLUSIONS: LVH is correlated with the severity of diastolic dysfunction manifested by the E/A value and deceleration time, but inappropriate LVM can slightly predict diastolic dysfunction severity in uncomplicated  hypertension.KEYWORDS: Echocardiographic, Left Ventricular Mass, Left Ventricular Hypertrophy, Diastolic Dysfunction
