| Abstract | ||
| Background: It is well known that hypertension results in cardiac overload. This overload is more profound on the left ventricle were systolic high pressure is present resulting in stiff LV. Objective:To evaluate the index of myocardial performance and stiffness index in patient with hypertension. Patients and Methods: This study enrolled 105 hypertensive patients and 60 control subjects .Patients with hypertension having an average BP ≥ 140/90 mmHg. From application of pulse wave echocardiography, the followings parameter are measured: Isovolumetric time of relaxation (IVRT), Isovolumetric time of contraction(IVCT) and time of Ejection (ET) to calculate Myocardial Performance Index (MPI). Results: The results showed that in hypertensive patients the isovolumetric contraction and relaxation time were increased while the ejection time was decreased, so increasing the index of myocardial performance (IMP) obtained as an indicator for all age groups. Conclusion: The myocardial performance index increases with increased hardness coefficient of the cardiac ventricular. | ||
