Acute myocardial infarction (AMI) is one of the most common diagnosis in hospitalized patients in industrialized countries. Left ventricular diastolic function is recognized as an important contributory factor in the pathophysiology of many common cardiovascular diseases. The aim of this study was to assess the left ventricular diastolic dysfunction by tissue Doppler imaging in acute myocardial infarction and to assess the clinical correlation with the tissue Doppler imaging.

Materials and Methods:

            This was a prospective study done between August 2016 to July 2017 at the department of Cardiology, Government Mohan Kumaramangalam Medical College, Salem. We had enrolled 100 patients who were referred to our department for the management of acute myocardial infarction.

Results:

            The study group consisted of 100 patients with acute myocardial infarction including 82 males (82%) and 18 females (18%) after informed consent for study. Mean age of the patient was 53.09 ± 6.4 (25 to 74) years. Median delay of thrombolysed patients was 8 ± 1.5 hrs (6.5 hrs to 9.5 hrs). All the selected patients underwent standard Doppler and TD echocardiography. Thrombolysed patient showed average E/Ea Value 14.5 and non thrombolysed patients showed average E/Ea17.4.

Conclusion:

            In the present study it showed increased morbidity and mortality in patients with E/Ea value more than15. Tissue Doppler imaging is a simple noninvasive investigation to diagnose  the diastolic dysfunction and prognosticate the patients with acute myocardial infarction.
