| Abstract | ||||
| Background: ischaemic cardiomyopathy isone of the common causes ofhigh mortality and increasing prevalence of heart failure. Because of the need to treat the cause of ischemic cardiomyopathy, testing of patients and detection of myocardial viability is much important and can help to identify viable segments of myocardium that have great chance of improving after revascularization. Noninvasive imaging are used for detection of viability and 2 dimensional speckle tracking echocardiography is under research for this. Aim of the work: Detection of myocardial viability in ischemic cardiomyopathy using 2D speckle tracking Echocardiography versus myocardial perfusion imaging. Patients and Methods: The ethical approval was obtained from the hospital ethical research committee and each patient entering the study signed an informed consent. Fifty patients included in this study with known ischemic cardiomyopathy. They were recruited from outpatient clinic at Al-Hussien Hospital during the period from October 2017 to July 2018. Myocardial perfusion imaging and 2D speckle tracking echocardiography with segmental longitudinal strain and global longitudinal strain were done to the fifty patients. Results: 2D speckle tracking echocardiography with segmental longitudinal strain and global longitudinal strain when compared with myocardial perfusion imaging predicted cutoff point for viable segment from nonviable with detected sensitivity and specificity. Conclusion: The new echocardiographically-derived myocardial deformation indices, which reflect structural changes assessed by transthoracic echocardiography can be used to detect myocardial viability. | ||||
