Abstract
INTRODUCTION : Coronary artery disease remains the leading cause of mortality and morbidity. Earlier thought to be a disease of the modern world, it has been found to be equally or even more prevalent in underdeveloped and developing countries. This disease is, unfortunately, being witnessed in the younger population also. It remains the most common single cause of mortality and morbidity in men below 65 years of age. Diastolic dysfunction is the primary mechanism responsible for dyspnea in patients with heart failure, irrespective of the presence or severity of systolic dysfunction. AIM : The aims of this study were; 1. To assess the left ventricular diastolic dysfunction by tissue doppler imaging in acute myocardial infarction. 2. To assess the clinical correlation with the tissue doppler imaging. CONCLUSIONS : 1. Thrombolysed patients showed average E/Ea value 14.8 and non-thrombolysed patients showed average E/Ea 17.1. 2. This study showed increased morbidity and mortality in patients with E/Ea value more than 15. 3. Tissue doppler imaging is a simple noninvasive investigation to diagnose the diastolic dysfunction and prognosticate the patients with acute myocardial infarction. 4. Pulsed Tissue Doppler imaging for myocardial velocities is far more practical, as the analysis can be performed on-line and does not require sophisticated time-consuming post-processing and which makes the method useful for daily clinical practice. 5. The proposed method is technically simple and can be easily performed using any echo machine equipped with conventional pulsed Doppler myocardial imaging. 6. Pulsed TD derived echocardiographic methods are quantifiable, reproducible, and noninvasive techniques for assessing the presence of diastolic dysfunction in acute myocardial infarction.
