Objective: Early detection of diastolic dysfunction in hypertensive patients to reduce complications and improve outcome. Place of Study: East Medical and Cardiology wards of Mayo Hospital Lahore. Study Design: A descriptive cross-sectional study. Patients and Methods: 51 hypertensive patients between 50 - 80 years of either sex enrolled through out patient department of Mayo Hospital Lahore underwent Doppler Echocardigraphy and data was analyzed by using Chi-square and Students `t` tests. Results: The percentage of left ventricular hypertrophy (LVH) was 66.66%. On comparing hypertensive patients with and without LVH, E and A wave velocities, E:A ratio, deceleration time and isovolumic relaxation time were similar. Conclusion: 33.33% of patients had no LVH in the presence of diastolic dysfunction so LVH was not an independent factor associated with abnormal flow patterns in hypertensive patients with normal systolic contractility. Impaired relaxation was the predominant pattern of diastolic dysfunction an d increased further with age.
