Dobutamine Induced ST- Segment Changes in patients with Acute MyocardialInfarction and its role in detection of MyocardialIschemia, Viability and Ventricular Dysynergy
Doha Mahmoud Fahmy Haggag;
Abstract
Dobutamine stress echocardiography has been proposed as a s:1tand well tolerated. non in\'aSi\'e stress testing for detection of coronary artery disease.
The aun of the present work was the detection of ST chang.:s during dobutam ine stress test. with assessment of myocardial viabi I ity. and lett
\'entricular dyssynergy.
This study included 15 patients: all of them were males. 11•ith a m.:an age of 53.9 years ± 9.5 suffering from recent acute myocardial inE1rction (within 2 weeks). Two of them had previous attacks: six had receiv.:d thrombolytic therapy. Eight patients had inferior myocardial infarction and seven had anteroseptal infarction.
All patients had no contraindications to dobutamine stress ec hocardiography.
Every patient was subjected to history - -ng clinical exa,m. ination. resting ECG. resting echocardiography, stress electrocardiography, and dobutamine stress echocardiography (DSE).
Determination of heart rate and blood pressure at each stage of the dobutamine infusion allowed quantification of the level of stress.
