Abstract              Background: Left ventricular hypertrophy confers an increased mortality independent of other cardiovascular risk factors. Echocardiography offers clinicians a quick assessment of changes in LV function resulting from hypertension. The M-mode and two-dimensional (2D) echocardiographic findings of LV mass are more sensitive and specific. In present study, an attempt has been made to assess left ventricular diastolic dysfunction in hypertensive cardiomyopathies with various echocardiographic parameters. Material and Methods: A total of 50 consecutive hypertensive patients with blood pressure (BP) more than 140/90 mm of Hg (JNC VII Stage I and II) at two or more recordings after an initial screening were included in this cross sectional study. Echocardiographic evaluation was done by 2D, M mode and Doppler echocardiographyon GE (Logiq 3) expert model no. AY-15 CUI. Results: Advancing age proved to be an important risk factor for the development of left ventricular diastolic dysfunction in patients of hypertension. The findings on echocardiography correlated well with the clinical condition of patients. Discussion: Echocardiography allows for rapid, noninvasive assessment of LV function in hypertensive patients. It can evaluate morphological and hemodynamic changes acutely and over time. Parameters obtained with echocardiography mayhelp in management and care for patients.
